WordPress 3.0 has just been released and it features a ton of really awesome features. In the video below, I walk through how setup WordPress 3 and enable the multisite mode, which allows you to have multiple WordPress websites powered by one installation. The setup is easy but can be tricky until you see it done. Enjoy!
Here’s the code you’ll need to copy/paste into your wp-config.php file:
define('WP_ALLOW_MULTISITE', true);

Great tutorial – any idea how to have domain mapping for WP3 multisite?
I believe you would use the domain mapping plugin but I haven’t tested it to see if it’s compatible with WP3. That is what was used with WP mu. I’ll do a test over the weekend see how it pans out.
I assume we are talking about having the same WP 3.0 installation run more than one domain name, right?
My question is: If we do go ahead and run more than one site on a WP 3.0 installation, and then choose to sell one site, then, how would that go? The buyer would only expect to set up a single site WP 3.0 installation.
That is in fact what London was talking about. On how to separate sites once it’s on the same install, that is something that I would need to dig a little more on. I would say use a different install if you intend on selling it so that it’s really clean cut.
Excellent tutorial. Exactly what I was looking for! Now to go build more sites, lol!
Glad you liked it Michael. Good luck with your new websites.
Thanks! Just setting up a multi-site Wordpress project. perfect timing with 3.0 coming out!
I installed older ver of Word Press through cpanel how can I put that code in now.
Utilize the Auto Upgrade feature (Tools > Upgrade > Automatically Upgrade) and then follow the instructions in the above video.
this kinda worked, but all my new sites i create are 404 not found, the main site still works fine though
I wonder if it’s an issue with the .htaccess file. Try going to Settings > Permalink and then hit save over there.
Try editing your Apache configuration and on the line inside your config change:
AllowOverride None
with:
AllowOverride FileInfo
Restart apache config to make effective the change.
ya i tried that, i tried changing the permissions on .htaccess as well.
it’s my first wordpress installation so i might of missed something somewhere
if i change a setting in permalinks, and then save it, then going to posts on my main blog doesnt work anymore either, it’s as if .htaccess isnt being updated either
ya i tried that, im not sure it’s actually updating .htaccess
if i change a setting in permalinks, then all of my original posts are no longer found either
but if i change it back to default it works again

Sorry for the brief message, because I gotta go now.

link is what I found relevant to your problem.
Yeah it is a .htaccess update issue. Just turn Allow Override All in your web server httpd.conf file.
I try this multisite configuration on my localhost ubuntu, there no option for sub-domains or sub-directories. is it okay?
after I click install, the configuration set to directories.
Great tutorial. Clear, well explained, one of the best. Thanks!
Very nice tutorial.
Unfortunately, my multisite configuration failed at step 1, and the tools menu failed to present the “Network” configuration option. Wordpress reports that my install is current.
Would you please suggest a next step in the diagnosis?
Thanks,
Mark
Great tutorial.
I guess it does take care of maintaining only one set of plugins? They are not replicated in any way, right?
Great vid, sooo much easier this way than the MU way
Superb tutorial! I did it in no time, although I must admit I was really nervous about it in the beginning.
Thank you for this!
Hi Melvin, great tutorial there. Makes it looks so easy. I messed up the first installation of the multisite by choosing subdomain, instead of subdirectories. Now everytime i try installing again, WP jumps this part thus blocking me from being able to choose subdomain or subdirectories. Is there anyway of clearing the cache so that I can make a clean installation? I’m using WP 3.0.3.
Thanks for any feedback!

That is fantastic wordpress multisite tutorial – it helped me, i have just got my new blog and wanted install wordpress multisite, thank you for that tutorial.
I followed your tutorial, thank you. I am experiencing one problem though, when creating a new website, and viewing it online, all the CSS is broken from the TwentyTen theme that was there by default. I installed wordpress into a directory off the root named /wp/.
