HowTo Install WordPress MultiUser Edition

What is WordPress MU?

    WordPress MU is multi-user version of the famous WordPress blogging application. It is ideal for people wanting to offer a hosted version of WordPress, but due to its complexity installation and maintainance is not supported in the same manner WordPress is. (You cannot get support on the WordPress support forums.)”

WordPress Multi-User Edition has a pretty active forum but I couldn’t find any installation guide. This is how I installed WordPress MU and I’m presenting a step-by-step installation procedure with screenshots.

The installation was done in CentOS and should be pretty much same in most of the *nix flavors. I’ve used the domain name mu.nirlog.com which was setup internally to capture screenshots for this tutorial. You won’t be able to access it from outside.

1. Create a wildcard entry in your DNS record for *.yourdomain.com to resolve to your server’s IP address.

In Bind DNS Server following two lines should be inserted in the zone file of nirlog.com. The domain for Multi-User Blog would be mu.nirlog.com where users can register their own blog e.g. test.mu.nirlog.com


    mu         IN    A    192.168.1.1
    *.mu    IN    A    192.168.1.1

2. Add a ServerAlias in Apache configuration file for *.yourdomain.com.

In Apache 2.x, configuration add the following line in virtual domain setting:

    ServerAlias *.mu.nirlog.com

3. Get the WordPress Multi-User Edition from the WordPressMu download site

    wpmu-unstable.tar.gz

4. Make sure you fulfill the requirements (according to WP MU site)
Apart from WordPress Requirements
Apache mod_rewrite – if you had WP installed already with fancy URLs then you should be fine.
Apache FollowSymlinks must be switched on. This will disappear in later releases.

5. Start Installation
Untar wpmu-unstable.tar.gz into your web directory. It’ll create a wpmu-… directory, change that name to wpmu. After this you can basically follow the instructions in your browser.

So, the real steps should go as following:

    tar xvfz wpmu-unstable.tar.gz

Which creates

    wpmu-2006-02-01

Rename it:

    mv wpmu-2006-02-01 wpmu

6. Fix the permissions (not very secure, but won’t work without it)

    chmod 777 wpmu
    chmod 777 wpmu/wp-inst/
    chmod 777 wpmu/wp-inst/wp-content/


You won’t be able to go further without fixing the permission

7. Enable Virtual Server Support by choosing Virtual Server Support: Yes. This will enable the registering users to have a sub domain of their choice.

8. Enter the MySQL Database information and press Submit.

    How can i On the feature of MOD_rewrite
    in my webhost .

  6. Gourav,
    if you have root access to your server, you should uncomment (remove the ‘#’ pound sign) the following line in you apache configuration file “httpd.conf” to load the mod_rewrite module. If you don’t have the root access, you should ask your web hosting company to do so:

    LoadModule rewrite_module modules/mod_rewrite.so

    That’s loading the module and it’s turned on by the wordpress(mu) in “.htaccess” file with following line:

    RewriteEngine On

  8. Rahul,

    recently WebFaction had been in the news for their excellent home grown web control panel and support for one click installation of applications such as Rails, Django, TurboGears and Zope. The price is also quite cheap.

    I don’t use their service but I was impressed by their control panel demo. You can give it a try.

  10. GOURAV,

    how does the link look like? In my case it looked as following:
    http://newblog.yourdomain.com/wp-login.php

    You have to make sure to create a wildcard entry in your DNS record for *.yourdomain.com to resolve to your server’s IP address, which is the first step mentioned in installation process.

  11. gourav says:

    SO plz help me.

  14. There seems to be an extra slash (//) after “wpmu” in the link.
    The link is like this:
    http://amit.mindsolinc.com/gourav/wpmu//wp-activate.php?key=6b8c891cf5914913
    If you remove one slash like this:
    http://amit.mindsolinc.com/gourav/wpmu/wp-activate.php?key=6b8c891cf5914913
    It should work.

  15. Rick says:

    Niranjan,
    Would you install WordPressMU on my GoDaddy.com account for a fee. I’m not very savy on editing code on the server, but would love to give MU a whirl to see what it does.
    Thanks

  16. Rick,
    I would be happy to help you. I’ve sent you an email with details. Let me know if you have any queries. The most important thing is that your hosting provider should fulfill the system requirements of wordpress mu.

  19. Hi Gourav,

    Login to wordpress –> “Write” –> “Write Post” there should be a “Trackback” box at the bottom. You can include the URLs you want to trackback there.

    As for the image upload, I also had a problem during my installation. Maybe this discussion thread can help you.

  20. gourav says:

    Hi

    I know that where the option of trackback.
    But i dont know that wht URL i should use there. And whts the meaning of Trackback. Can u give me a example.

  21. Gourav,

    check if this helps you.

  22. Pazman says:

    Niranjan, are you assisting with installation with the MU?

    Can you install into a subdomain?

    Are the pic uploading issues mentioned within the posts here fixed?

    Can you limit what is seen within the admin section? If so what can be elimated?

    Can you add plugins/themes?

    Can we talk?

  23. Hi Pazman,

    I’ve outlined the basic installation steps in the post and if you have any specific questions, either other readers or I’ll try to help. wp mu forum is other good place to go for help.

    Yes, you can install wpmu in subdomain. I didn’t follow up with the pic uploading issues but I think it’s fixed because I’ve seen other sites using the feature. I’m not sure about the admin section limitation but the plugins/themes should be ok.

    Sure, we can talk. You can send me email via contact me

  24. Tabrej says:

    I was trying to install it on my internal IP but it gave me some error.

    Not sure how to fix it.

    Can I install WPMU on shared hosting account?

  25. nanangms says:

    Install WPMU with Controlpanel 11 is easy. Try this …

    If your hosting work with subdomain unlimited and Control Panel 11 your hosting is ready and no need anything again to install WPMU.

    Try this:
    from Controlpanel 11 create subdomain * (This is asterix, your subdomain like *.yourdomain.com)
    Install WPMU and create database.
    Chmod public_html and wpcontent and .htaccess to 777
    continue install WPMU.
    Finish.

    WPMU work 100%. Try my test page (only for test) at http://iklani.co.cc
