O aviso “Erro ao estabelecer uma conexão com o banco de dados” no WordPress é um erro fatal que torna seu site inacessível aos usuários. Isso acontece quando o WordPress não consegue se conectar ao banco de dados.
Como vários fatores podem afetar essa conexão, o erro pode ser um pouco difícil de solucionar para iniciantes.
Há 16 anos, administramos nosso blog no WordPress e encontramos vários erros e avisos, inclusive o “Erro ao estabelecer uma conexão com o banco de dados”. Com nossa experiência e muita tentativa e erro, aprendemos a solucionar esses problemas sem interromper nosso site.
Neste artigo, mostraremos como corrigir facilmente o “Erro ao estabelecer uma conexão com o banco de dados” em seu site WordPress, passo a passo.
Qual é a causa do erro ao estabelecer uma conexão com o banco de dados no WordPress?
Um banco de dados é um software que facilita o armazenamento, a organização e a recuperação de dados de outro software.
Como um sistema de gerenciamento de conteúdo, o WordPress usa um banco de dados para armazenar todo o seu conteúdo e outros dados do site. Em seguida, ele se conecta ao banco de dados sempre que alguém visita seu site.
O WordPress precisa das seguintes informações para se conectar ao banco de dados:
- Seu nome de banco de dados
- Nome de usuário e senha do banco de dados
- Servidor de banco de dados
Essas informações são armazenadas em seu arquivo de configuração do WordPress, chamado wp-config.php.
Se alguma dessas informações estiver incorreta, o WordPress não conseguirá se conectar ao seu servidor de banco de dados e você verá o erro “Error establishing a database connection” (Erro ao estabelecer uma conexão com o banco de dados).
Esse é um dos erros mais comuns do WordPress. Além das credenciais incorretas, esse erro também pode aparecer se o servidor do banco de dados estiver inativo ou se os arquivos do banco de dados estiverem corrompidos.
Dito isso, vamos dar uma olhada em como corrigir o problema “Erro ao estabelecer conexão com o banco de dados” no WordPress com uma solução de problemas passo a passo.
1. Verifique as credenciais do banco de dados do WordPress
Credenciais incorretas são a causa mais comum do erro de conexão com o banco de dados. Se você mudou recentemente seu site do WordPress para um novo host, provavelmente esse é o problema.
Suas credenciais de banco de dados do WordPress são armazenadas no arquivo wp-config.php. Esse é o arquivo de configuração do WordPress que contém configurações importantes, inclusive informações sobre o banco de dados.
Se você nunca editou um arquivo wp-config.php antes, dê uma olhada no nosso guia para iniciantes sobre como editar o arquivo wp-config.php para obter mais instruções.
Você procurará as seguintes linhas no arquivo 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' );
Aqui, você deve se certificar de que as informações sobre o nome do banco de dados, o nome de usuário, a senha e o host do banco de dados estejam corretas.
Você pode confirmar essas informações no painel da sua conta de hospedagem do WordPress. Para este tutorial, usaremos o Bluehost, mas o processo também será semelhante para outros painéis de hospedagem.
Ao fazer login, clique na guia “Website” na coluna da esquerda e, em seguida, mude para a guia “Advanced” (Avançado). Em seguida, role para baixo até a seção “Database” (Banco de dados) e clique no botão “Manage” (Gerenciar) ao lado dela.
Isso abrirá a página Bancos de dados MySQL no cPanel em uma nova janela.
Aqui, você pode encontrar o nome do banco de dados e o nome de usuário na seção “Current Database” (Banco de dados atual). Não se esqueça de copiar e colar esses detalhes em um bloco de notas para poder adicioná-los ao arquivo wp-config.
Em seguida, role para baixo até a seção “Current Users” (Usuários atuais), onde você pode clicar no link “Change Password” (Alterar senha) ao lado do nome do seu banco de dados.
Isso o levará a uma nova tela, na qual você poderá alterar a senha do banco de dados de acordo com sua preferência.
Depois de confirmar todos os detalhes do banco de dados, você poderá alterar essas informações no arquivo wp-config.php, se necessário.
Depois disso, tente visitar seu site novamente para ver se o erro de conexão com o banco de dados desapareceu.
Se você ainda puder ver o erro, isso significa que algo mais está errado.
2. Verifique as informações do host do banco de dados
Se tiver certeza de que as informações de nome do banco de dados, nome de usuário e senha estão corretas, certifique-se de que está usando as informações corretas do host do banco de dados.
A maioria das empresas de hospedagem WordPress usa o localhost como seu host de banco de dados. No entanto, algumas empresas de hospedagem gerenciada do WordPress usam servidores separados para hospedar bancos de dados. Nesse caso, as informações do host do banco de dados não serão localhost.
Isso significa que você precisará entrar em contato com a empresa de hospedagem do WordPress para confirmar esses detalhes.
3. Reparar o banco de dados do WordPress
Agora, você pode estar recebendo um erro diferente no painel wp-admin, como “Uma ou mais tabelas de banco de dados não estão disponíveis” ou “O banco de dados pode precisar ser reparado”. Nesse caso, você precisa reparar seu banco de dados.
Você pode fazer isso adicionando a seguinte linha no arquivo wp-config.php. Certifique-se de adicioná-la logo antes da linha “That’s all, stop editing! Happy blogging”:
define('WP_ALLOW_REPAIR', true);
Depois de fazer isso, você poderá ver as configurações visitando esta página: http://www.yoursite.com/wp-admin/maint/repair.php. Apenas certifique-se de substituir yoursite.com por seu próprio nome de domínio.
Aqui, você deve clicar no botão “Repair Database” (Reparar banco de dados) para iniciar o processo.
Observação: o usuário não precisa estar conectado para acessar a página de reparo do banco de dados. Quando terminar de reparar e otimizar o banco de dados, remova essa linha de código do wp-config.php.
No entanto, se não quiser adicionar nenhum código ao site, você também poderá reparar o banco de dados usando o cPanel da sua conta de hospedagem.
Vá em frente e visite sua conta de hospedagem, onde você deve abrir a página “Websites” na coluna da esquerda. Em seguida, vá para a guia “Advanced” (Avançado) e clique no botão “Manage” (Gerenciar) na seção Database (Banco de dados).
Isso abrirá o cPanel em uma nova guia. Aqui, role para baixo até a seção “Modify Databases” (Modificar bancos de dados) e escolha o nome do seu banco de dados no menu suspenso “Repair Database” (Reparar banco de dados).
Depois de fazer isso, basta clicar no botão “Repair Database” (Reparar banco de dados) para iniciar o processo.
O painel de hospedagem agora reparará automaticamente o banco de dados para você.
Quando o processo for concluído, você também verá uma mensagem de sucesso.
Agora você pode visitar seu site do WordPress para ver se o erro foi resolvido ou não.
4. Verificar se o servidor de banco de dados está inativo
Se tudo parecer estar correto e o WordPress ainda não conseguir se conectar ao banco de dados, o servidor do banco de dados(servidor MySQL) pode estar inativo.
Isso pode ocorrer devido ao tráfego intenso em um servidor. Seu servidor host simplesmente não consegue lidar com a carga (especialmente quando você está em uma hospedagem compartilhada).
Devido a isso, seu site ficará lento e poderá até mesmo gerar um erro para alguns usuários. Nesse caso, você deve entrar em contato com o provedor de hospedagem por telefone ou chat ao vivo e perguntar se o servidor MySQL é responsivo.
Além disso, se você tiver outros sites em execução no mesmo servidor, poderá verificar esses sites para confirmar se o servidor SQL está inativo.
Se você não tiver nenhum outro site na mesma conta de hospedagem, basta acessar o painel de controle de hospedagem e alternar para a guia “Avançado”.
Depois disso, clique no botão “Manage” (Gerenciar) ao lado da seção phpMyAdmin.
Isso abrirá o phpMyAdmin em uma nova janela, na qual você deverá clicar na opção “Database” (Banco de dados) na parte superior.
Depois disso, clique no nome do banco de dados para acessar suas configurações. Se conseguir fazer isso, então é hora de verificar se o usuário do banco de dados tem permissões suficientes.
Para fazer isso, você precisa criar um novo arquivo chamado testconnection.php e colar o seguinte código nele:
<?php
$link = mysqli_connect('localhost', 'username', 'password');
if (!$link) {
die('Could not connect: ' . mysqli_error());
}
echo 'Connected successfully';
mysqli_close($link);
?>
Ao colar o código, certifique-se de substituir o nome de usuário e a senha pelos seus próprios. Agora você pode carregar esse arquivo no seu site e acessá-lo por meio de um navegador da Web.
Se o script for conectado com êxito, isso significa que o usuário tem permissões suficientes e que outra coisa está causando o erro.
Agora, você deve voltar ao seu arquivo wp-config e verificá-lo para garantir que todos os detalhes estejam corretos e sem erros de digitação.
Soluções adicionais que funcionaram para os usuários
Se as dicas de solução de problemas mencionadas acima não conseguirem corrigir o erro de conexão com o banco de dados em seu site, você poderá tentar estas etapas adicionais.
Conforme relatado por nossos usuários, essas etapas ajudaram alguns deles a resolver o erro de conexão com o banco de dados em seus sites.
1. Atualize o URL do site WordPress
Você pode tentar atualizar o URL do site do WordPress usando o phpMyAdmin no cPanel.
Basta acessar o phpMyAdmin no painel da sua conta de hospedagem e selecionar o banco de dados do WordPress na lista.
Depois disso, mude para o menu SQL na parte superior e digite a seguinte consulta MySQL:
UPDATE wp_options SET option_value='YOUR_SITE_URL' WHERE option_name='siteurl'
Ele deve ter a seguinte aparência:
Não se esqueça de fornecer o URL do seu próprio site e alterar wp_options para o nome da sua própria tabela, pois você pode ter alterado o prefixo da tabela do WordPress.
2. Reinicialização do servidor da Web
Os usuários de servidores dedicados, servidores locais e servidores virtuais privados (VPS) podem tentar reiniciar seus servidores.
Isso reiniciará seu servidor da Web e de banco de dados, o que pode corrigir algumas falhas temporárias que estão causando o erro.
3. Pedir ajuda
Se tudo o mais falhar, talvez seja necessário entrar em contato com a empresa de hospedagem na Web. Todas as boas empresas de hospedagem WordPress o ajudarão a solucionar o problema, indicarão a direção certa ou até mesmo o resolverão para você.

Thank God I found this article. Replacing wordpress database password and username with my cpanel login credentials got me through it.
Adrian Ramos
Thank you!
i solved the problem by changing my new username and password in the wp-config file.
Regards
Paul
Thank you very much!
Giorgos
Another solution that worked. Delete the current MySql user and add a new one. It’s a solution for this specific error:
Access denied for user ‘foo’@’%’ (using password: YES)

Hi, Im a long way in to my blog with txt and pictures however, I am new to this and now finding my uploading of media is freezing 4/5 in and goes to error. Looking on the web found many others have had this problem, however, the common stream is increase image memory I’ve only used 115 MB what’s going on does anyone know? I’m very frustrated as I can try and try for HOURS sometimes to upload
Thank you

Had this error pop up yesterday on my ten year old Wordpress installation that is hosted @ GoDaddy.
Turns out GoDaddy changed the Hostname for the SQL server. updated the DB_Host value and all is working fine.
Thanks for the detailed post about this issue.
Bhavesh
I do have same issue with GoDaddy, tried everything out from this post and others.
but not get any result.
After heading everything I just tried to change the user name as it was same as database name before.
and the issue solved.
so thought the issue is having database and username is same for the DB.
Kaustav Banerjee
Super effective article. It has just happened with me. The most common mistake of all is the difference between password set for database user from backend and the one mentioned in wp-config .How could I forget this…
Thanks a lot!!
alex.s
One thing that needs to be mentioned that if you are using MAMP the password for the database is root as a default. This little thing took me hrs to figure out.
Dlee
Thanks for this guide, it really saved me! I changed my database password not realizing what would happen, I managed to fix it thanks to this guide though
Dev
If it helps, I would like to add that my particular problem occurred when I updated the password to my database through godaddy, and the wp-config file did NOT update the password, I had to go in manually to change it.
/** MySQL database password */
define(‘DB_PASSWORD’, ‘PasswordGoesHere);
Jesse Josserand
I pretty much had to do everything above including changing the password in wp-config. After all that… and editing my sql backup I was restoring so that it used the correct db_name and username and password, as well, everything started work except for errors caused by problems with the super cache plugin. I’m still fighting that issue, but hallelujah to God and all y’all above for getting me this far!
David Kley
This is why we use Joomla more than Wordpress.
Easier to move, easier to set up quickly, easier to troubleshoot. Wordpress makes it a huge pain if you want to move your site to another server or change domains. To each their own though. Each has it’s own set of weaknesses.
Bev
I have the problem intermittently and randomly. It doesn’t stop the site from working entirely, the ‘error establishing a database connection’ message shows up randomly (both backend and frontend). My host says the problem is a plugin conflict. I’d be happy to test that but because the problem is random, I can’t tell immediately if deactivating a plugin will help. Arrggh!
Steph
We started having this issue recently as well. We contacted our host and they said it sounds like our database is either maxing its connections or our tables are locked during a call (which would most likely happen from a plugin).
WPBeginner Support
You could deactivate all plugins and try to reproduce the error.

Hi, in my case it was been problem in bad domain values in table wp_blogs. There must be valid domains.
Good Luck!

Thanks you bro.. very very much..it workd..
I am very happy..luv you so much..I am on GoDaddy and i just placed the testfile.php and it workd..Thank you very much <3 <3 <3 <3
Joel Donfak
I had the same issue with a new website and I finally found that the MySQL username in the CPANEL was not linked to the database. After doing it, it work properly!
So make sure the problem doesn’t come from there.
Ed
I changed my MySQL password for security reasons and updated it right away in wp-config but now I get the “Error Establishing a Database Connection” on both front and back end. I know my login credentials work as I can connect fine to phpMyAdmin.
– I tried a fresh re-install of Wordpress via FTP (without overwriting wp-config or wp-content folder) and that didn’t help.
– I am trying to do the database repair method mentioned above but I can’t even access that page as it won’t let me get past the database connection error.
– I tried the test connection method and get the following error:
Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /srv/users/serverpilot/apps/xxxxxx/public/testconnection.php on line 2
Warning: mysql_connect(): Access denied for user ‘root’@’localhost’ (using password: YES) in /srv/users/serverpilot/apps/xxxxxxxx/public/testconnection.php on line 2
Error: Access denied for user ‘root’@’localhost’ (using password: YES)
None of these solutions work! Please help someone! I haven’t touched my wordpress site or made any changes prior to the mySQL password update so I know it’s not a wordpress code or plugin issue. Would nginx or cache effect this?
dev
Go to wp-config file and find this:
/** MySQL database password */
define(‘DB_PASSWORD’, ‘PasswordGoesHere’);
Make sure the password matches what you use to log in to your database.
Kyle Coombs
So, I have always accessed WordPress via the internet and never downloaded the client onto my computer. I’ve always wondered why someone would want to do that and now I think I understand why after receiving this same error message.
I’m curious, can I do any if I cannot access my WordPress account to make these changes listed? Or do I need to contact my host or hope that problem resolves itself?
Just checking if there’s anything I can do on the front end.
Dave_Whittle
I had this error yesterday, and to make a long story short, the solution was as simple as restarting MySQL, i.e. issuing the following commands from the command line:
sudo mysql stop
sudo mysql start
Shoaib
Thanks this one helped me

I was trying to load my website (from backups) to a new hosting company today. It was tricky figuring out how to make it work. Ended up installing and uninstalling a bunch of times due to some mistakes. I first tried loading my wordpress files via FTP and creating a new Mysql database manually in my hosting control panel, but I could not get the two to see eachother and could not import my backed up SQL file to the new database, finally figured out (after some trial and error), i needed to install a fresh wordpress from my hosting control panel which installs wordpress for me and creates a database. Once there is a linked database you can drop all the tables, and import the backed up database. I would then upload my wordpress backup via FTP on top of the fresh install and choose ‘Overwrite’. When it finished, I had the front page of my website showing up like it was working, but all the pages were “object not found, no database, or page outdated, please notify the author, etc.”…. I tried repairing/optimizing the database, which did not help…. I updated my wp-config file with the right database info, which did not fix it….So I uninstalled everything and started over many times (uninstalling reinstalling with the same results — FINALLY WHAT WORKED. fresh wordpress install via my control panel, I used the same username password for the admin that I previously had used on my old site (this helped my new wordpress “see the mysql backup” better once I imported it), then FTP the wordpress backup files on top of the fresh install with overwrite option. change the wp-config code to the new database info (mine was a new database name/pw everytime i reinstalled wordpress). After I did all of this I was getting the front page but still getting “object not found” pages for everything else. BUT now I could login to my admin…. once I was at this point, I realized that wordpress or the server wass checking itself (updating itself) after all of the major changes I had made via FTP and MySQL…. basically just wait, I think I waited a half hour to an hour and I started seeing my other pages (without graphics), took a nap, and then all the pages were there. I only had a few pages and posts but after such major changes, the server had to catch up and verify itself, I think…
Jhood
Just wanted to share my experience – I received this error when I created my account in cPanel with a user name that was more than 8 characters long. Apparently it confused the Wordpress installer, and it couldn’t create the database.
So I just deleted the entire Cpanel account and started over with a cPanel user name of 8 characters – worked like a charm!
Sarah Baker
I tried just about all these things and nothing worked – just about but not all. I’m not an expert but not a beginner. Finally, I decided to delete the account from the server (new site with no data yet), start over, and install Wordpress manually. I use Rochen which uses cPanel and Fantastico and it’s only been recently that I’ve been having this problem.
Installing manually worked fine and I had no problems. Will be submitting a support ticket to Rochen for sure.

I built my site on an Amazon ec2 instance and frequently get the Error establishing database connection on both the frontend and backend. what I do that always solves the problem is telnet into the server and restart mysqld. But I was wondering what the underlying issue was that is always causing this error to recur. any ideas??
shaun2k
You’re running out of RAM and memory management is killing your mysqld process. You will need to upgrade to an instance that has at least 2GB RAM. I’m tipping you’re on free tier and you have 1GB of RAM.
KyleM
For me what worked was changing localhost entry in wpconfig.php to 127.0.0.1; they may work with out doing all of the above so its a quick. I must say all this data above was a good start for me to understand the problem and root cause.
Christina Torres
Totally random, and maybe this is dumb, but I realized my problem on Mac was that it kept changing a regular ‘ into a stylized one in text edit every time I added in my username, password, database name, etc, even as a text file. weird. anyway, thanks for the help!
Colin Murphy
Just incase other people have had the same issue you get this error also on a multisite installation if the URL’s in the wp_blogs are not set correctly . I had this issue this morning when moving the site from my dev version to staging.
Jack Bobeck
I just experienced it on our site, first time. So I did as you recommended, called Bluehost, our host provider to find out WTH? They said that our database is limited to 15 connections at once, and that because of activity, when you hit that ceiling, you get that error. So they suggested we run a test on all of our plugins and see if there are some that are hogging connections, then run a program that converts our pages to HTML pages as a backup, in case people want to access the site as a backup and do so in a quicker manner. I hope this makes sense, not an expert web guy, but just repeating best I can. But best thing to do first is contact your host provider for answers.

I just had the same problem for my site. Went through the article and didn’t see anything out of the ordinary. messing around in wordpress I reset my ‘WP Super Cache’ plugin to the defaults and cleared it out and my site started working again.

Daniel DeNewasha
Intermittently I get the following error visiting the site. There’s absolutely nothing on major search engines with this error number alone. I can get to wp-admin, which is the sites login page with theme loaded, etc. and login. In Admin, I can do anything with no issues. Sometimes I can visit the site, other times not, even in different browsers, e.g., on refresh may or may not appear. Have done the repair and settings show no errors. I am on Godaddy shared hosting. Just finished building site so very little content, DB incredibly small 2mb on export.
“ERROR 677-402iqz. We’re sorry, error reading database, missing or
corrupt. This website is no longer unavailable.”
Any ideas anyone?
Thanks
Daniel
WPBeginner Staff
WordPress stores all your site’s information in a database, which is managed by a database server. If for some reason WordPress is unable to connect to the database server then you will get this error. Please contact your web hosting provider for support.
terry
I was trying to fix non appearance of widgets on my site when I got
“Could not connect to the DB Server!”
. Even when I just enter the site in the address box or include wp-admin.
I have no idea now. Just assume I am a 5 year old idiot if you reply.

If you’re getting on a welcome screen, then it means that you replaced your database credentials.

Hi my site has been off since this morning telling me Error establishing a database connection in french since it is a french website http://c2cteaching.com
I called my host who told me to modify my wp-config.php, and since we did I land on a welcome setting page of wordpress ! I’m getting crazy, what can i do ? help me please !
Vijay
Hi, I had this error show up on our primary domain, add-on domains and a sub-domain.
I use GoDaddy for hosting.
Long story short: We found that because for some reason the MySQL databases table inside hosting > databases didn’t have any users attached to the databases that the sites were showing this particular error.
Just below that table on the right hand side, there is a ‘Add User to Database’ section. I assigned each user to a database. So, i388299_wp1 was selected as user and i388299_wp1 was selected as the database and all the sites started working fine again.
So, there is a bug in GoDaddy that causes users to be deleted from that list for some strange reason.
karelles
I was trying to clean up and tossed some mysql servers (they’re all one anyway) that I thought I wasn’t using and one of my site alarms went off. Sure enough that site was using the server that I tossed. Changed to a different server (as I said they’re all one) in the wp-config file and all was again well. Thanks!!!
Vonnie Hudson
I had this problem today on my VPS. Error establishing connection to Database. Checked disk space and confirmed it was fine but memory usage was almost depleted. I ran sudo free -m and top to find the biggest offenders but couldn’t really figure it out. I had something like 5MB of RAM left. I even rebooted the server but that didn’t fix it. So I just waited and eventually it came back – my only guess at this point is that my server was inundated with too much traffic. But it’s a VPS so I don’t know what’s going on. I hope this doesn’t happen again tomorrow –
random guy
You need to get a fully managed cpanel VPS so that someone that knows what they are doing can assist you.
When you have 5mb of ram left, you are stuffed. The server would be slowing down immensely. From here, upgrading the ram, or installing cpnigix, or having someone fine tune the VPS, can all reduce your ram usage and improve performance.

WPBeginner Staff
Jacob, it seems like your database server is frequently down. Contact your web host or switch to a better WordPress Hosting provider.
As for the facebook issue we will recommend you to use WordPress SEO by Yoast. Once it is activated go to SEO -> Social and check the box next to Add Open Graph meta data.
Aaron Winters
I’m having same issue as Jacob had, but on my local install. In the time it takes to make an edit of any sort, I sporadically get sent to the “Error establishing a database connection” page. (Only on Admin side) 1 in 5 times it actually forwards past it on its own and completes the update, otherwise I have to copy the entire post, paste over the old, submit over and over until it finally accepts. Also happens on image uploads. No problem on the remote host that I know of.
Jacob Wall
I get the error sporadically – only when I’m signed into my admin account. Although one blog reader did inform me that once it took her 4 attempts to load the main page. It never lasts long, but happens often (4 or 5 times a day?).
Also, while I am writing blogs, I will often get a “Connection to server lost” error, and then I have to wait for it to reconnect before I can save. As I said, it never lasts more than about 15 minutes, but often enough so it makes writing blog posts a very time consuming process.
Finally, when I try to share on FB, the preview doesn’t show up – only a link. I have know idea if these three errors are related, but they seem to show up around the same time, and all three are too frequent.
