O WordPress 3.0 é o momento em que ocorre a grande fusão. O núcleo do WPMU é incorporado ao WordPress, o que significa que agora é possível executar vários blogs em uma única instalação do WordPress. Esse novo recurso está sendo chamado de opção de rede ou de vários sites. Por padrão, esse recurso está desativado. Se quiser usar essa opção em seu WordPress, será necessário ativá-la.
Para ativar esse recurso, basta abrir o arquivo wp-config.php localizado na pasta raiz do WordPress. Em seguida, adicione a seguinte linha em qualquer lugar do arquivo:
define('WP_ALLOW_MULTISITE', true);
Depois de fazer isso, você poderá acessar a página de rede em Ferramentas ” Rede
Agora, você não precisa mais instalar várias cópias do WordPress porque pode executar vários blogs em uma única instalação. Por padrão, você só tem permissão para executar outros blogs como um subdomínio. Para usar outros domínios para blogs, você pode usar um plugin de mapeamento de domínio.

Hi. Here is a link for those wanting to know more on the capabilities for Wordpress MS. A really good video explaining how Multisites work. http://wordpress.tv/2010/05/31/boone-gorges-wordpress-3-multisite/

Thanks for this tutorial as I was wondering how to install WP MS and your article greatly assisted me in doing so. Much appreciated.

I love the guide but I have run into a problem. I used your code and see the network option but I get the following message. <blockquote>”Error: Your WordPress address must match your Site address before creating a Network. See General Settings.”</blockquote>
Is this because my wordpress folder is in a folder?

good afternoon,
I am setting up a wpms and am attempting to set up a subdirectory with Geo sites. When I attempt certain names – I get the rejected saying is an invalid name or path. Is there a limit on the number of characters in the secondary name?
thanks

Thanks for a useful post – I take it we still have to edit the wp-config file to activate the MU features for WordPress 3.1 as well?
Do all plugins that work on single WP installations also work for multisite?
Editorial Staff
Yes, you would still have to edit the wp-config file to enable Multi-site. All well-coded plugins will work.

Hi everyone. First time in this site.
I’m really interested in WP MS function but I’m not pretty sure if this is what I (we) need.
I’m the webmaster of a university’s website and I wanted to install multiple WP in different sub-domains (like medios.uagricultura.com, biologia.uagricultura.com, escolar.uagricultura.com). Now, thanks to you, I find it may be possible to make a single WP installation and part from there but I need to have the main account of the installs plus one more guy/girl to administrate each sub-domain on its own and separate from the others ones. I mean, I need to administrate everything on demand but each section must have it’s own administrator/theme/active-widgets.
Would you recommend me to make a single WP MS installation or to keep one WP per sub-domain?
I’m a little old in WP knowledge but brand new in the administration side of it. Thank you in advance.
Editorial Staff
The Multi-Site option is what you need. You can be the network admin, and you can have one guy or girl managing each specific subdomain. Each section will have it’s own admin panel.
Administrador
César Pérez
Thank you so much for the quick reply. I’ll be working on this all the week. By the way. Love your site. I’ll be here for a long, long time.

Greetings – please excuse my basic question but does multisite work using different themes and entire domains? eg a http://www.xx.tv and a http://www.xx.com.au, accessed through the one administration section, where I can have a different look / theme for each domain?
I’ve always used godaddy so far for 1-click wordpress setup and hosting but am at a point where I need to setup 3 sites that each have a different theme and domain but ideally share content amongst them.
Would multi-site facilitate this or will I be recreating content / blog posts / pages in each ‘instance’ ? Thank you kindly for the information. I <3 WP
Editorial Staff
Yes Multi-Site allow you to use Domain Mapping (which lets you have two separate domains, two separate themes, two separate plugins etc). Godaddy is not the best host for this. Try using HostGator (coupon: wpbeginner).
Administrador
Rick Nielsen
Philip,
The staff here is right on. I have completed 3 Multisite installs on my HostGator hosting and it works great. GoDaddy is not the best place to host, in my opinion, much of anything. Have fun with Multisite!

Oh Thanks for information.

Drupal is worth a look too, maybe not a intuitive as Wordpress, and not so well supported, but good all the same. Wordpress does subdomains well though, if you can set up wildcards on your server (I think). I set up a WPMU once on a cpanel hosted site with no problems.
Jon
Edward, if you are running Wordpress on your own domain you are always in control. If you invest in Wordpress, then the worse case scenario is that the Wordpress community stop supporting it and you software stop being updated.
But if it works for you now, it will work in the future. Ok, there may be potential security threats raised in the future, but all you need is a sound backup plan and maybe a php developer to work on Wordpress for you. You site is independent of any core files on wordpress.org.
But in all honesty, Wordpress is probably one of the most durable CMS’ out there. So many people use it, it will always be supported.
Edward
Thank you Jon, now i can assure you i will have good sleep today. Iam really wondering why i never discoverred wordpress before. php code has eaten almost all my brain cells for the last one year! and never never came 10% near what wordpress has done for me in three days! you guys out there keep up the good work.
Edward
Thank again. one more thing. how would you rate the security and reliability of running hundreds of subdomains on wordpress platform. since it seems wordpress has quite control on the programme. could wordpress one day decide to call it a day and ground all networks including my personal domain running hundreds of subdomains? in other words how independent is my network from wordpress?
sam
Thanks for Sharing this very important article for create Wordpress Multisite.I followed all steps for Wordpress Multisite and i created on my own domain name.
Once again Thanks.
Edward
Am thankful for this blog. is it legal to create say 1000 blogs using wp with this technology and charge a little for maintenace and administrative work? is it possible to run ads from the main installation and they appear in all the blogs? or post announcements that appear in all blogs on my network? for instance can i place adsence ads that run on all blogs from one installation
Editorial Staff
Yes it is legal.

thanks so much for this …. really great tutorial.
i do have one question – is it possible to set up the sites so they have different languages? It would be great if the user could login once and blog across sites in multiple languages. i’ve previously been using multiple wordpress installs to do this which is not ideal.
Glenn
I did this to one of my new websites, and it worked wonderfully. However, I want to do this to my blog, and I want the (sub-directory) feature. But it says this when I try:
“Because your install is not new, the sites in your WordPress network must use sub-domains. The main site in a sub-directory install will need to use a modified permalink structure, potentially breaking existing links.”
Do you know how I would be able to do a “sub-directory” rather than a sub-domain?
neil
Thank you, man. Worked like a charm.
I have one question. If I have MS working, do I need BuddyPress, too?
Editorial Staff
You don’t have to get BuddyPress in order to use MS.
Administrador
JJ
Hi,
Many thanks for the tips. These proved very valuable.
I had 3 websites and Worpress installed in each of the 3 folders. I have now enabled the multi-site and made 2 of the domains “hang under” the main domain.
My question: what happens to the WP installation in those 2 subfolders?
Will their version number hang at say 3.0 whilst the main folder gets updated to 3.1, 3.2 etc.
Is there not a security risk and unnecessary use of webspace ?
Many thanks for clarifying.
Editorial Staff
No, once you upgrade the major install, all others will get upgraded as well.

It may be soud a little bit crazy but with Wp MS it is possible to show below an post comments from same post published on a different website? I want a mobile site but with only one category of it to be the normal site.

Hi! I got WP3 and multi user installed. Everything seems to be in working order. I’m a WP beginner and my objective for this new site is to have 3 blogs to go along with my Home, Shop, About and Contact pages. Blog #1 will be main blog, Blog #2 will be a wine diary, Blog #3 will be ideas on ideas to recycle wine bottles. I will have a menu to go to all 7 of these pages (all on the same website). I’m building the theme for this site in Artisteer. I’m trying to figure out how to actually use this Multi Site feature in order to make this happen. Will it even work for what I’m trying to do? If you have any links or tips on how to use it (multi-sites) once it’s installed that would be great too!! I appreciate your time and effort! Thank you!
Editorial Staff
Multi Site will surely work. WordPress Codex has an article on how to deal WPMU.

Anyone know how to enable the search across sites functionality? I need the subsites to be indexed in the search tool.
Aaron
You need a plugin to do sitewide search. Here is one such plugin: http://premium.wpmudev.org/project/global-site-search
Whatever plugin you choose, make sure it works for the Wordpress/MU version you are using.
Valerie
Thought I was crazy because I couldn’t get it working and realized it was just my impatience… the sub-domain just needed to propagate.
Warren Scott
I’m having the same problem as Rick Nieslen. I can create new sites but when I click on the link to activate it in the email I get page can’t be found.
My host said they set my server up for wildcard domains but I’m not sure how to check that it actually is.
Could you do a tutorial on how to enabel a network using sub-domains. Especially on step 2 setting up wildcard subdomains for apache servers.
While searching for answers I did find a plugin that will perform steps 3 through 5 of http://codex.wordpress.org/Create_A_Network
The plugin can be downloaded from http://wordpress.org/extend/plugins/wordpress-multi-site-enabler-plugin-v10/

I have just upgraded to 3.0 and was looking forward to playing with the multi-blog options. A little bit surprised that a manual modification of wp-config.php is required – why did Wordpress not put an option in the admin panel to turn it on?
Editorial Staff
Because not everybody needs it, and by putting an option there can confuse beginners.

Please help me understand what is wrong.
– firstly I create a subdomain using my CP hosting.
– I create a website using the dashboard and it’s there under ‘my sites’. When check the subdomain folder with my ftp client, its empty.
– I check /wp-content/blogs.dir/ and that’s also empty (I have 777 the folder)
Are there files uploaded to the subdomain automatically or what happens?
Editorial Staff
You do not need to create each subdomains in the cPanel. WordPress does that automatically.
Administrador
wizz
Thanks for the quick reply.
This is the problem. It doesn’t.
Is it because of the server blocking this action or because of something I missed installing the programme?
Thanks for your help.
Michael
Thank you for this posting.
I wonder why this information should be that hard to find.
should the multisite function be possible to just activate / de-activate from within the user interface?
I think so
Thank you once again; I got the information I was looking for
Michael
Mike
Hi,
I have followed all of the instructions as detailed above.
I have inserted the code in the wp-config.php, where you recommend.
I have also set up wild card subdomains in my DNS.
( I am running my sites on a Linux server through SEO hosting, which is part of Hostgator )
I do not get the NETWORK menu option coming up in tools.
Could this be because I have set up addon domains onto my primary ( account ) domain?
I have enabled wildcard subdomains for all of the addons as well and they are all upgraded to WP 3.
Any hints, tips or tricks are extremely welcome.
Thanks in advance,
Mike

I know (and have) installed wp in a aub-directory and run a site from there without interfering with the root domain site. But what if the people running the root domain decide to have the sub-directory wp site manage them in the future – how would that work?
Editorial Staff
For top level domains, you would need to use a Domain Mapping plugin. I think this is what you are asking for. If not then please email us.

As you all know that wordpress 3.0 is out there and have to upgrade them. You can run multiple websites in wordpress 3.0 and this tutorial will clearly indicated that how you do it.
My question is that could i need a new installation of wordpress will upgrading to wordpress 3.0 directly through dashboard will do the work or not and for integrating the other blogs on itcould mess up all the things or not. Need your opinion on this?
It would be a pleasure if you guys come up with a tutorial on “how to merge your blogs into one blog” badly needed at this time.
Rick Nieslen
Great website guys! You really know your WP stuff!
Here is an issue I’m have with the new WP 3.0 and the multi-blog feature: I think I did everything as stated in all the instructions I have read when I set it up. But when I create a new site using the sub-domain setting, I get a page can’t be found. I can get to the wp-admin on the sites I create, but cant see the public side of the site. I’m using HostGator for my host. Now I remember seeing some requirements that the hosting company may need to configure to make the multi user worked, but I cant remember..du.
Any insight with this issue would be greatly appreciated!
Thanks again for all you do.

i have 2 blogs, one is main & another one is sub domain, how can i combine both? mean: how to use single installation.
Editorial Staff
If you were using WPMU before, simply click upgrade and it will happen. If you have them on a separate database, then you need to export the backup file for your subdomain blog. Install WordPress 3.0 and enable multi site. Then you need to create a subdomain account in your network. Then import the posts and images using the export file that you had.

Will the new wordpress 3.0 allow for us to create a network of blogs like wordpress.com??? Meaning can I have other people create free wordpress sites from my 3.0 installation??? Or is the 3.0 installation for personal use???

You can give out usernames if you want with WPMU and you could do it with this one. Although extra customization will be necessary.

Great news! Finally, I used Movable Type 4 for a while, it was great because you could create as many blogs as you liked with only one installation, the downside was the lack of current plugins, themes, and overall support.
The downside to WPMU is the limited administration options in every blog except the original, and the very very very limited kitchen sink, do you know if by enabling this option there other blogs you create will be limited like in MU?
Editorial Staff
This will be just like MU, so if you considered MU to be limited, then yes.

I’m currently working with both MU and WP3.
My view on MU is that it is clunky and a swine to configure.
I’m seriously considering changing my MU install back to WP3 because it’s such a pain to work with.
Downside 2: Wishlist member does not work with MU
Apart from that though there are some gorgeous templates etc
Cheers,

if you want to use sub domains make sure your home url & site url is set to http//domain rather than http//:www before you enable multisite it will try and configure your sub domains like this http//subdomain.www.domain.tld
