Så här fixar du error vid upprättande av en anslutning till en database i WordPress

Ser du notisen ”Error establishing a database connection” i WordPress?

Detta är ett fatal error som gör din site otillgänglig för användare. Det inträffar när WordPress inte kan upprätta en anslutning till databasen. Eftersom flera faktorer kan påverka denna anslutning kan error vara lite svårt att troubleshoota för Beginner.

I den här artikeln kommer vi att visa dig hur du enkelt fixar ”Error establishing a database connection” på din WordPress site, steg för steg.

Fix the Error Establishing a Database Connection in WordPress

Vad orsakar error vid upprättande av en anslutning till en database i WordPress?

En database är en programvara som gör det enkelt att lagra, organisera och hämta data från andra program.

Som ett system för hantering av innehåll använder WordPress en database för att lagra all your content och andra data på din website. Den ansluter sedan till databasen varje gång någon besöker din website.

WordPress behöver följande information för att ansluta till databasen:

  • Namnet på din database
  • Database användarnamn och password
  • Server för databaser

Den här informationen lagras i din WordPress-konfigurationsfil, som heter wp-config.php.

Om någon av dessa uppgifter är felaktiga kommer WordPress att misslyckas med att ansluta till din server för databasen och du kommer att se felet ”Error establishing a database connection”.

Database connection error in WordPress

Det är ett av de vanligaste WordPress error. Förutom felaktiga credentials kan detta error också dyka upp om databasens server är nere eller databasfilerna är korrupta.

Med detta sagt, låt oss ta en titt på hur man fixar ”Error establishing database connection” issue i WordPress med steg-för-steg troubleshoot.

1. Kontrollera din WordPress Database Credentials

Den vanligaste orsaken till error i anslutningen till databasen är felaktiga credentials. Om du senaste har flyttat din WordPress site till en new server, så är det troligen detta som är problemet.

Credentials för din WordPress-databas lagras i filen wp-config.php. Det är konfigurationsfilen för WordPress som innehåller viktiga settings, inklusive information om databasen.

Om du ej har redigerat filen wp-config.php tidigare kan du ta en titt på vår guide för nybörjare om hur du redigerar filen wp-config.php för mer instruktioner.

Du kommer att leta efter följande rader i filen wp-config.php:

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define( 'DB_NAME', 'database_name_here' );
/** MySQL database username */
define( 'DB_USER', 'username_here' );
/** MySQL database password */
define( 'DB_PASSWORD', 'password_here' );
/** MySQL hostname */
define( 'DB_HOST', 'localhost' );

Här måste du se till att informationen om databasnamn, användarnamn, password och server är korrekt.

Du kan bekräfta denna information från instrumentpanelen för ditt WordPress dashboard. För denna tutorial kommer vi att använda Bluehost, men processen kommer att vara liknande för andra webbhotell paneler också.

När du har loggat in klickar du på fliken ”Website” i den vänstra kolumnen och växlar sedan till fliken ”Advanced”. Rulla sedan ner till sektionen ”Database” och klicka på knappen ”Manage” bredvid den.

Click the Manage button next to the Database section

Detta kommer att öppna sidan MySQL Databases i cPanel i ett new fönster.

Här kan du hitta ditt databasnamn och användarnamn i sektionen ”Current Database”. Tänk på att copy and paste dessa details till ett anteckningsblock så att du kan add to dem till wp-config-filen.

Find your database name and username in the Current Databases section

Därefter rullar du ner till sektionen ”Current Users”, där du kan clicka på länken ”Change Password” bredvid namnet på din database.

Du kommer då till en new vy där du kan ändra lösenordet för databasen så som du gillar det.

Change your database password

När du har bekräftat all din database details kan du ändra den informationen i din wp-config.php-fil om det behövs.

Efter det kan du försöka besöka din website igen för att se om error i anslutningen till databasen har försvunnit.

Om du fortfarande kan se error betyder det att något annat är fel.

2. Kontrollera informationen om servern för din Database

Om du är säker på att uppgifterna om databasens namn, användarnamn och password är korrekta, är det bra att kontrollera att du använder korrekt information om databasens server.

De flesta webbhotell för WordPress använder localhost som server för din database. Vissa hanterade WordPress-värdföretag använder dock separata servrar för att servera databaser. I så fall kommer din databas serverinformation inte att vara localhost.

Detta innebär att du måste kontakta ditt webbhotell för WordPress för att bekräfta dessa detaljer.

3. Reparera WordPress Database

Nu kanske du får ett annat error i wp-admin adminpanelen som gillar ”One or more database tables are unavailable” eller ”The database may need to be repaired”. I så fall måste du reparera din database.

Du kan göra detta genom att lägga till följande rad i din wp-config.php-fil. Se till att add to den precis före ”That’s all, stop editing! Trevlig blogg”:

define('WP_ALLOW_REPAIR', true);

När du har gjort det kan du se inställningarna genom att besöka den här page: http://www.yoursite.com/wp-admin/maint/repair.php. Se bara till att ersätta yoursite.com med ditt eget domain name.

Här måste du klicka på knappen ”Repair Database” för att starta processen.

Repair WordPress database

Note: Användaren behöver ej vara inloggad för att komma åt reparationssidan för databasen. När du är klar med att reparera och optimera din database, se till att ta bort den här kodraden från din wp-config.php.

Men om du inte vill add to någon kod till din site, kan du också reparera din database från ditt webbhotell kontos cPanel.

Gå vidare och besök ditt webbhotell konto, där du måste öppna sidan ”Websites” från den vänstra kolumnen. Gå sedan till tabben ”Advanced” och klicka på knappen ”Manage” i sectionen ”Database”.

Click the Manage button next to the Database section

Detta kommer att öppna cPanel i en new tab. Här rullar du ner till ”Modify Databases” section och väljer namnet på din database från ”Repair Database” dropdown menu.

När du har gjort det klickar du bara på knappen ”Reparera databas” för att starta processen.

Click the Repair database button

Webbhotellets panel kommer nu automatiskt att reparera din database åt you.

När processen är completed kommer du också att se ett success message.

Database repair success message

You can now visit your WordPress site to see whether the error has been resolved or ej.

4. Kontrollera om din server i databasen är nere

Om allt verkar vara korrekt och WordPress fortfarande inte kan anslutas till databasen, kan din databasserver (MySQL server) vara nere.

Detta kan hända på grund av tung trafik på en server. Din server kan helt enkelt inte hantera hämtar (särskilt när du har delade webbhotell).

På grund av detta kommer din webbplats att bli långsam och kan till och med mata ut error för vissa användare. I det här fallet bör du ta ett telefonsamtal eller chattsupport med din hosting provider och fråga dem om din MySQL server är responsiv.

Om du dessutom har andra webbplatser som körs på samma server kan du kontrollera dessa webbplatser för att bekräfta att din SQL-server är nere.

Om du ej har någon annan site på samma webbhotell account, så går du bara till din dashboard och byter till tabben ”Advanced”.

Därefter klickar du på knappen ”Hantera” bredvid phpMyAdmin section.

Click the Manage button next to the PHPMyAdmin option

Detta öppnar phpMyAdmin i ett nytt fönster, där du måste klicka på alternativet ”Database” högst upp.

Därefter klickar du på namnet på din database för att komma åt dess Settings. Om du kan göra det, är det dags för dig att kontrollera om din databas användare har tillräckliga behörigheter.

Connect PHPMyAdmin with your database

För att göra detta måste du skapa en new fil som heter testconnection.php och klistra in följande kod i den:

<?php
$link = mysqli_connect('localhost', 'username', 'password');
if (!$link) {
die('Could not connect: ' . mysqli_error());
}
echo 'Connected successfully';
mysqli_close($link);
?>

När du klistrar in koden, se till att ersätta användarnamn och password med dina egna. Du kan nu uploada filen till din website och komma åt den via en web browser.

Om skriptet ansluts utan problem betyder det att din användare har tillräcklig behörighet och att det är något annat som orsakar error.

Nu måste du gå tillbaka till din wp-config-fil och skanna den för att se till att alla detaljer är korrekta och utan några stavfel.

Ytterligare lösningar som har fungerat för användare

Om de ovan nämnda felsökningstipsen inte lyckas fixa felet i anslutningen till databasen på din webbplats kan du prova dessa ytterligare steg.

Som våra användare har rapporterat har dessa steg hjälpt några av dem att lösa error i anslutning till databasen på sina webbplatser.

1. Update URL:en för WordPress site

Du kan försöka updating URL:en för WordPress site med hjälp av phpMyAdmin i cPanel.

Gå bara in på phpMyAdmin från din dashboard på webbhotellet och välj din WordPress database från listan.

Följ detta genom att gå till SQL-menyn högst upp och enter följande MySQL sökning:

UPDATE wp_options SET option_value='YOUR_SITE_URL' WHERE option_name='siteurl'

Det ska se ut så här:

Change site URL

Glöm inte att ange din egen site URL och ändra wp_options till ditt eget tabellnamn, eftersom du kan ha ändrat WordPress tabellprefix.

2. Starta om web server

Användare på dedikerade servrar, språkversioner och virtuella privata servrar (VPS) kan försöka starta om sina servrar.

Detta kommer att starta om din web server och database server, vilket kan fixa några tillfälliga problem som orsakar error.

3. Be om hjälp

Om allt annat Misslyckas, då kan du behöva kontakta ditt webbhotell. Alla bra webbhotell för WordPress kommer att hjälpa dig att troubleshoota problemet, peka dig i rätt riktning eller till och med fixa det åt dig.

    Either ’127.0.0.1:8889’ or ’localhost:8889’ works for me. Just using ’localhost’ with no port specified does not work. I am using MAMP

  3. Joe

    The frontend of my site is connecting but the wp-admin section is showing the error establishing a database connection.

    What do I do?

  4. ALEX

    Thank you, it worked!!! :)

  5. Gill

    Thanks! Life saver. Completely borked my site changing passwords. Could have sworn I’d done everything right but managed to fix it in config.

  6. Praveen

    My problem was due to a google analytics plugin, the day i installed it, my site was down saying ”Error database connection!” Even I was unable to login into my admin panel. So, I manually removed that plugin from cpanel, and everything worked.

    • Andreja

      Hi Praveen,

      thank you for your info. Can you please explain how to find particular plugin in cpanel to remove it? I received this error message right after I’ve installed ”All in one SEO pack” plug-in in my Worpress site so I guess it could be the same problem as your problem was…?

      Thank you in advance!

  7. Matt

    I was on a Digital Ocean 512MB droplet and was getting this error every couple of weeks. Inspecting the logs showed that a process called update-apt-xapi was consuming all of my memory and causing the mysql service to crash resulting in the error. You can try setting up a swap file but, really, 512MB just isn’t enough memory to run a WordPress install. Upgrade your droplet to 1GB and that should take care of the issue.

    • Joween Flores

      We have the same issue here friend. How’s your website going since? I was trying to cheap on server expenses now.

  8. Ob

    I just checked MySQL server with ”service mysql status”. Apparently, MySQL server was not running.
    So, I started it with: ”service mysql start”. And Voila! my website was up.

  9. Kishan SHarma

    What i found is it was faulty plugin which was causing trouble , try deactivate plugins and check if problem persist. changing localhost to 127.0.0.1 also solved some issues

  10. Jim Zimmer

    I did a search through your post and didn’t find anything about SELinux being the culprit, which ultimately was my problem. I have segregated my web server from my database and disabled SELinux on both VMs. I tried your testconnection.php, which was successful from within the /var/www/html directory before disabling SELinux, so I really have no idea if it is the database or the web server that has the issue. I will try and update this comment with SELinux settings that work when I have tested it.

  11. Andrea

    I have this problem right after having changed the password for my admin access. Can you super kindly provide a solution written in a language understandable for someone who has close to 0 programming or web-developer knowledge?? I have the error for both front-end and back-end. I have NO IDEA how to ”check the wp-config.php” file (never heard of it until now). How do I proceed?

    Thank you so much,
    Best,
    Andrea

  12. Binyam

    What did work for me was this: In cPanel, go to Advanced Zone Editor select the domain copy the recorded IP and as wpbeginner suggested I replacing localhost with the IP and it works! Thanks!

  13. Avinash

    I was having the connection problem. The problem was my previously installed MySQL, was running. So I stopped it and then ran MySQL of Xampp. It worked. Hope it helps.

  14. Avinash

    My previously installed mySQL was running. I stopped it and then ran mySQL that came with Xampp. it worked. Hope it helps.

    We had our wordpress installed on AWS EC2 and we got the ”Error establishing database connection” for all our sites when the database was installed on the same server as the web server. When the database was moved to Amazon RDS for each of our sites, that error did not recur.

  16. Luis Daniel

    Hi!
    This helped me a lot with a WP installation going bad. Thanks!

  17. Scott

    Greetings.

    I have recently experienced the same issue when moving my multi-site from a subdirectory to root. Even after going through all the steps outlined in various tutorials, I encountered this dreaded message and nothing I did seemed to work.

    What did work for me was this: In cPanel, go to your softaculous script installer, select the edit icon for your WordPress installation, change the paths that point to your install.

    Once I did this and saved, then navigated to my site URL, it was back up and running smoothly.

    Just wanted to leave this here in case it helps someone else along the way.

  18. John Henry Gaspay

    Thanks man, it work on ngnix server due to error establishing.

  19. Sysy

    I have an issue with database connection. I wanted to create a new database for a new website #2 connected in multisite in OVH, and when wordpress asked me to enter login, password etc I entered those of website #1 as I had to do BUT without changing ”wp_” for ”wp_2″… And now both of these two sites have the message ”Error establishing a database connection”. I deleted all FTP WP for website #2 and deconnected from multisite, but impossible to get back and to enter in website #1!! Do you know how to resolve this problem?

  20. Taurai

    I’m having an issue with my website, my WordPress database just seams to disappear. logged into MySQL and nothing exist there anymore. has anyone ever experienced this? anyone with a solution?

  21. Gail Gardner

    The cause of this issue when I had it was so many people running hacking programs against my login page that they were impacting the server. It happened every Friday evening through Sunday evening.

    We eliminated the issue by protecting that page with a pop-up so they couldn’t run their automated hacking programs against the login page.

  22. Rita

    Thank you for posting this–it saved a bit of a panic when the company’s WP blog disappeared behind this error. After verifying that the database was still there and undamaged, I called our host.

    Turns out they’ve been migrating customers’ web sites to new and improved servers, and they somehow lost the connection info. Hopefully it will be repaired today.

    But a very informative article, and a quick reminder (for me) of how to check in on mySQL to make sure everything is still good. Thanks!

  23. adams

    i cant create pages, new post, or edit my themes or even upload pictures i constantly get the following error…

    This page isn’t working.
    didn’t send any data.
    ERR_EMPTY_RESPONSE
    the website setup is new but am faced with this problem

  24. Wayne

    Thanks. Helped me debug a DB backend issue.

  25. jitesh

    How can i find my wordpress database username and password?

    By Mistake, i have deleted wp-config.php file and now i have uploaded new files.

    I am Using Godaddy’s windows server…

    I am getting below error:

    This either means that the username and password information in your wp-config.php file is incorrect or we can’t contact the database server at . This could mean your host’s database server is down.

    Are you sure you have the correct username and password? Are you sure that you have typed the correct hostname? Are you sure that the database server is running? If you’re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

    Please help me as I have wasted by complete week…

    Thank you..

    • WPBeginner Support

      Hey Jitesh,

      You can login to your hosting control panel and locate the MySQL database section. Most likely, you will be able to find the database name, username, and password information there. Alternately, you can contact support to help you locate that information.

    Thanks so much, all, for maintaining such a great website! You guys continue to bail me out with problems, issues & fixes for those of us who just enjoy writing & posting and not dealing with all of the WordPress programming stuff. Great work!
    Cheers!!!!

  27. Joette

    Thanks for all the great articles. I am having such a problem tho just getting WP installed. I’ve followed your instructions regarding doing it with MAMP and keep getting the ”can’t connect to localhost:8888” msg. After much searching I found a terminal code to test apache. It returned with httpd not running, trying to start. I did it again and it didn’t return anything so perhaps worked.

    I tried connecting to local host again and this time I got Error connecting to database. At least this seems like progress! I tried some of your suggestions above and this time, it seemed to be trying to connect for quite a while, but finally gave me the Error connecting to database again.

    I have yet to get the happy WP page. Does anyone at all have any ideas as to what is going on? I have spent hours searching, contacting, trying this and that and I don’t know what else to do at this point. I am an absolute WP beginner.

    Thanks to anyone/everyone in advance.

    • Ashley Knox

      Hey! Were you able to figure it out? I’ve tried all of their solutions and I’m still stomped.

      • Joette

        Hi Ashley, No, unfortunately nothing is working for me either! I’ve yet to find someone who knows the answer & have been asking many places. For me, I think I’m going to use different software and leave WP for another time. Too strange, too much hassle.

        • Kalico

          This isn’t a WordPress problem, it’s a MAMP problem. If you have to run this on a local server, try a different XAMP package. Better yet, get a shared hosting account and set it up there. Local XAMP can be frustrating.

  28. J M Landers

    I missed that when you add the repair line to your WP config file you have to add it right at the end of the declarations before the first ”if” statement when I first read it. Took me a while to realize what I was doing wrong. Still didn’t fix my problem but at least I was able to strike one possible issue off my list.

  29. Muhammad Qamar40391

    Thank you for a great helpful post.
    Solved by resetting DB password but this process repeated several times. issue solved but page speed is too much slow now.

  30. John Malto

    Also had the same problem and tried everything. TestConnection was failing. What I just had to do was manually edit the user password through MySQL Cpanel and it suddenly worked!

  31. Leslie limardo

    I am so confused. First time on wordpress. No tech experience whatsoever. I didn’t receive any error. message. My website is up. The problem I had is when I set the page to update some updates would take effect and others didn’t. I called WordPress and they told me I didn’t set up the database correctly. Is this the same issue as this article or something totally different? Thanks in advance.

  32. Fran

    Hi, i had this problem when I formatted my laptop and reinstalled XAMPP.

    Problem was, I forgot to create a new Mysql user with the same data (host, name and password) from my BD user stored on wp-config.php, just like we do when we configure one new WP site for the first time. That solved it :)

    So, maybe the problem is not that the user has not enough permissions… perhaps the problem is, user simply doesn´t exist yn mysql.user table! (as I said, it can be possible after formatting your computer).

  33. Ahmed

    thank you for the great help, i got mine up by replacing localhost with 127.0.0.1

  34. Kate

    I just had the same problem, which I managed to solve by simply changing the DB password and correcting that in the config.php file.

    I have no idea why the password suddenly became an issue, though.

  35. Sheriph

    Changing the localhost in my wp-config.php to the ip on my host account in godaddy cpanel did the magic for me. Even godaddy support were talking rubbish. Imagine telling to upgrade with about $200, that my hosting plan is low on resources. I almost believed until I found this article. Thanks a lot.

    • Steve

      I still have the problem. GoDaddy tried but unable to help. They have a service that, for $80.00, will have a WordPress expert investigate. However, there are no guarantees she / he can fix the problem but you still have to pay the $80.00.

  36. Destiny Alabi

    This review was very helpful,

    I had a similar issue with installation on windows server, I kept getting database error, and what I did was to replace localhost which was internal server to IP Address and Port which was external server and it worked perfectly.

  37. Sam

    Mine just happened like 20 minutes ago, I am hosting at Ipage and WHAT A SCARE!!! It happened all over sudden and I could not access both the admin site and the website itself with my laptop but I could access the site with my phone.
    Then before I could complete reading this guide the site got back by itself lol. I want to know if there is a way to avoid this from happening in future.

    • Robin Robin

      The same happened with my site. Very strange!

    I have no WordPress account, but have been having this happen to me a lot recently on several sites. How can I fix this? (Note: I don’t own these other sites and I don’t think I can access their databases directly)

  41. imparthi

    Thanks much for the article. I ran into the same issue.
    1. Wp-Config file was correct
    2. phpMyadmin connection was success
    3. testconnection.php approach too was success
    4. I tried to update the site URL I couldn’t get it as naming conventions of the table names of the WP changed

    THIS IS WHAT HELPED ME FINALLY.
    I selected wp_Options” table in the phpMyAdmin window to browse the content, there was an informative Error message that, the table has to be repaired. (wp-config auto-repair didn’t work out)

    I was able to repair using the options available in phpMyAdmin and got my site back. :) Thanks all.

  43. Tanya

    Hi there,

    Thank you for this article. My website was hacked recently and after I got no support from the hosting provider, I was told I was going to need to reinstall WordPress and upload the backup. I didn’t use a backup plugins (I am all the way in South Africa) as it is to expensive for the paid plugins. So I did a cpanel backup through Softaculous and downloaded the Zip of 1.03Gig. Two weeks later my site was hacked (Twice in one week). With the second hack my wordpress installation was comprimised – and backup deleted from server. So I had to delete the original installation and reinstall. Now I followed all the steps to upload the zip to file manager and now I am stuck with this: Error Establishing a Database Connection. I have tried all the suggested solutions from this post, but still no progress. Please help me! I am quite new to wordpress and this is my biggest client’s website.
    Kind regards,
    Tanya

    • WPBeginner Support

      Hi Tanya,

      The most common reason for this error is incorrect Database information in your wp-config.php file. Confirm that you have restored your WordPress database correctly, then enter the mysql host, database name, database username and password carefully. If you are unsure, ask your hosting provider and they will let you know your mysql host and other information.

      Hope this helps

      Administratör

  44. Mannu

    Some folks suggested that they fixed their problem by replacing localhost with the IP.

    It worked for me….
    Any logical explanation for this…?

    • Nick

      Think about it. ’Localhost’ is the name of a location. If changing that to the IP works, then ’localhost’ was not pointing where you need it to be.

  45. Andrew

    Thank you for your article, it was very informative and helpful in getting my issue resolved.

  46. Ravi

    I have MAMP installation on my Macbook. i.e I am running MySQL also on my local machine. My problem was that in wp-config.php, the database server ’localhost’ is not working. Once I changed it to 127.0.0.1, it started working.

  47. Amanda

    What does it mean if testconnection.php is just a blank white page?

  48. Mike Crisp

    Repair database command worked for me.
    Front end or site was fine but couldn’t access admin panel – Repair found a damaged database file (wp-options) – repair worked

  49. JP Hoey

    What i did was, in the cPalen i went into MySQL databases and scrolled down to current user and changed the password. I used the very same password that was in my wp-config.php file but for some reason the password was corrupt. Everything works fine now.

    • Chuck Moran

      I got this error on a client’s site. After a bum steer chatting with a Bluehost tech, I called back and the phone tech support person I got did this same @JP Hoey trick (changing the DB pass and updating it in wp-config.php). Took 5 minutes and worked like a charm.

  50. Adam Coalbow

    An obscure one for me…

    Don’t use #’s in your password.

    I had two hash tags in my password that was throwing something off in the PHP–since hash tags create comments I guess. I removed the hash tags and BOOM, I’m in.

  51. Ted Richards

    First thank you for a well-documented article on ”We were able to connect to the database server (which means your username and password is okay) but not able to select the XXXXXX database.”

    I tried almost everything outlined in the article but can’t fix my problem. Here is an outline and history.

    Local machine installation:
    I have installed MySQL 5.7.17 and MySQL WorkBench 6.3.8. And WordPress 4.7.2. The MySQL was installed after removing both an earlier version of MySQL and WorkBench. The previous version was displaying the same database error. The previous WordPress/MySQL worked about 2 years ago, but recently I contracted a project to develop a WordPress Web site, and I encountered this problem when I began setting up the new WordPress framework for this new site. The old WordPress site was deleted so I couldn’t test if that worked.

    So, I reasoned, why not try a fresh start and also upgrade to the latest versions, etc.

    But, this new version also had the same problem with not being able to connect to the database. I have narrowed down the problem to ”permissions” and I haven’t been able to crack the code.

    The MySQL Server logs verify this is this case:
    Timestamp, Thread, Type, Details
    2017-01-28T02:46:24, 134, Note, Access denied for user ’root’@’localhost’ (using password: YES)

    I have created a new WP directory and installed a fresh WP version etc.
    I deleted and created new databases in WorkBench and properly assigned them users and passwords.

    I have checked the Users and Privileges, Client Connections and can find nothing that would block access to the database.

    I have checked my Windows 7 permissions for the MySQL Directory and the sub directories. I have unchecked the “Read Only” to the master MySQL Directory and all directories and files are read/write.

    I have progressed through each attempt to connect to the database each time I change something.

    I am exhausted and very disappointed there isn’t a good response by the WP Support Team to this issue of “not able to select the database.” It is a “popular” issue that many developers are experiencing with no resolution–many more experienced than me, are having.

    You are my last hope!

    Thank you!
