WordPress MU

Hello,

I have WordPress installed locally and want to install WordPress MU in another directory. Whenever I go to "localhost/wpmu/index.php" in my browser to run the install I get the following error:

Warning: constant() [function.constant]: Couldn't find constant VHOST in /var/www/wpmu/wp-settings.php on line 100

Warning: constant() [function.constant]: Couldn't find constant VHOST in /var/www/wpmu/wpmu-settings.php on line 33
No WPMU site defined on this host. If you are the owner of this site, please check Debugging WPMU for further assistance.

I realize this error has been reported a million times but I'm having a lot of trouble making sense of everything.

OS: Ubuntu Hardy Heron
Regular WordPress Directory: /var/www/
WordPress MU: /var/www/wpmu

I followed the instructions in the readme and did to following:

1. Created a new database called wordpressmu and a user by the same name with rights to the database.

2. to "/etc/apache2/apache2.conf" I added:
LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so

3. to "/etc/apache2/apache2.conf" I changed "AllowOverride None" to "AllowOverride FileInfo Options"

4. The next step I did not do because I could not find the <VirtualHost> section in Apache2.conf. I'm sure that the problem has something to do with this but I'm at a total loss as to what to do.

Any help would be tremendously appreciated. Thank you.

You're missing the config file created during the install process. Do a search on the error around the forum, there's tons of topics on it.

You're also using localhost as a domain. You need to use a correctly formed domain for the install. ie: localhost.tld

MrBrian, tdjcbe,

Thank you for your help. I realize questions from somebody who doesn't know what they are talking about can be frustrating. I appreciate your patience. I forgot to mention: I'm running Ubuntu Hardy Heron Desktop Edition (not server).

1. I've looked around the forums for help with the config file. I'm having trouble making sense of it. I think the config file is missing because no installation process took place at all, I just go the above errors.

2. I'm unsure how localhost.tld works. tdjcbe, when you say "Use a correctly formed domain for the install. ie: localhost.tld" are you referring to the url I type in to get to the WPMU install screen? Or are you referring to something I would fill in AT the WP install screen (which I can't get to)?

3. The ReadMe says to set up the <VirtualHost> stuff and the DNS setup for subdomains before running the installation. I have not done these steps because I really don't understand what I'm supposed to do.

4. I would like to run the multiple blogs with subdomains as opposed to subdirectories, though, I'm not sure if thats possible given the fact that WPMU is currently in a subdirectory of my /var/www/ folder. Not sure if I'm missing anything required to do this.

You have to set up your box so localhost is localhost.tld (or whatever, as long as there's an extension). Set it up to show /var/www/wpmu as its own local domain.

the vhost stuff *has* to be done if you want subdomains.

But, ike you said, gotta get to the install screen first. ;)

andrea_r,

Thanks for responding.

-How do I set up my box so localhost is localhost.tld? Do I need the install screen do to that?

-Is the process of setting up localhost.tld any different since i'm attmeping to install WPMU alongside regulard WP in a sub directory?
Wordpress is installed in "/var/www/"
WPMU is currently in: "/var/www/wpmu/"

Thanks for your help.

Frank

Andrea wasn't exactly correct.

You need to set up your apache vhost to answer for "domain.tld", then modify /etc/hosts to add the following: 127.0.0.1 domain.tld

Now, "domain.tld" could be whatever you want it to be. It could be test.loc, site.home, etc. The main point is that there is a name and extension format. Since it's all local, for testing I'm assuming, it doesn't matter what it is.

If you're playing with subdomains, you'll have to add them to /etc/hosts as well. So your line might look like:

127.0.0.1 domain.tld text.domain.tld test2.domain.tld

Under live server circumstances, you wouldn't be editing your hosts file since there would be live DNS covering it.

Oh, and make sure the vhost (in apache) for MU is set with a path to the wpmu directory.

lunabyte,

Thanks for the help. So let me make sure I get what your saying. I need to do the following:

1. Set apache to answer to domain.tld. To do this would I edit the apache2.conf file and add in:
<VirtualHost *>
ServerName domain.tld
DocumentRoot /var/www/wpmu
</VirtualHost>
NOTE: I do not see any <virtualhost> area in the apache2.conf at the moment.

2. Then add "127.0.0.1 domain.tld" to /etc/hosts

3. QUESTION: For using subdomains, where does adding a "*" hostname record that points to the webserver come in?

4. QUESTION: Instruction #3 in the ReadMe says to add: "ServerAlias *.domain.tld" to the config file to make it work with subdomains. Is this config file created after the installation is run?

Thanks!

Dear FGazerro,

I'm having the same problem exactly like yours.. Have you found the solution..?

Look in the httpd.conf file guys, you need to add that stuff in there.

sorry, i wish to ask a novice question as i not really know much about server setting.

if i'm using a shared hosting service, when i add a subdomain for wpmu.domain.com, will the setting added to httpd.conf automatically?

or i need to ask my service provider to do that for me?

Send the readme file to your webhost.

Andrea_r,

Thanks for your patience.

So,

1. All the <virtualhost> stuff goes in httpd.conf? My httpd.conf is empty and seems to use Apache2.conf isntead. Does it matter which I use?

2. Then I update etc/hosts like we discussed earlier?

3. Where exactly does adding a " * " to the hostname record for subdomains come in?

4. lunabyte said "...make sure the vhost (in apache) for MU is set with a path to the wpmu directory." Is the "vhost" lunabyte referred to the <virtualhost> section of httpd.conf/apache2.conf?

I apologize for all the questions. I'm very new to working with servers. Ya'll have the patience of saints. Thank you!

Frank

my webhost is not helpful...

can i ensure something... is this application not supported for share hosting?

@siteblob Nope, not really.

well, i think i should change to a better hosting company instead..

Thanks for your help andrea_r...

Hey guys,

It still won't work. I'm running Ubuntu Desktop with Apache2. I keep getting the same errors:

Warning: constant() [function.constant]: Couldn't find constant VHOST in /var/www/wpmu/wp-settings.php on line 100
Warning: constant() [function.constant]: Couldn't find constant VHOST in /var/www/wpmu/wpmu-settings.php on line 33
No WPMU site defined on this host. If you are the owner of this site, please check Debugging WPMU for further assistance.

I have done the following:

1. Added the following to "/etc/apache2/apache.conf"
"LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so"
And added "AllowOverride FileInfo Options" to the <Director> section.

2. Created a new file in "etc/apache2/sites-available" called "wpmu.loc". In that file, I copy and pasted the contents of the default file in the sites-available directory and modified it accordingly. (I'll copy and paste the contents at the bottom of this message.

3. I added wpmu.loc to "/etc/hosts". The line looks like this:
127.0.0.1 localhost wpmu.loc

4. Restarted Apache.

Still won't work.

Please help me.

Frank

Contents of the "sites-available" file i made:

I know i'm stupidly late to this topic but with Ubuntu all you need to do to access a locally installed WPMU is to find out your pc's hostname. This is as simple as opening a terminal and typing "hostname". It will then tell you your hostname.

michael@michael-nouto:~$ hostname
michael-nouto

All I had to do after that is type http://michael-nouto/ and it took me straight to my local site.

That'll bring you to your site but that will still cause issues with wpmu. The software needs a two tld domain to work with.

Oh right i'll file that away. Thanks tdjcbe.

Not a problem.

As an aside, is this setup check no longer working? We've had threads recently on this and the use of IP addreses.

I'm just concerned.
