Hi all,

I have just installed and configured Apache on our new Linode which runs CentOS 6.
I also configured virtual hosts and it is working fine.
I have also installed and configured MySQL and PHP.
However, I have uploaded some applications like mysql to the default apache document root:
/var/www/html

but navigating via our server's IP this way: http://123.123.123.123/phpmyadmin

brings up:
"Not Found

The requested URL /phpmyadmin was not found on this server."

almost as if it is not calling up the default apache document root.

Could I have been doing something wrong?

To my undersanding, virtual hosts should not affect the default document root. Is this thinking right?

Thanks in advance for your help.

Do you have a VirtualHost block with 123.123.123.123 as either ServerName or ServerAlias? If not, then Apache will route requests for 123.123.123.123 to the first VirtualHost block it finds, which might not be the one you think.

Thanks @hoopycat.

Here's what the VirtualHost section of my Apache configuration file looks like:
<VirtualHost *:80>
ServerAdmin webmaster@mysite1.com
DocumentRoot /var/www/vhosts/mysite1.com/httpdocs/
ServerName mysite1.com
ServerAlias www.mysite1.com
<Directory /var/www/vhosts/mysite1.com/httpdocs/>
AllowOverride all
</Directory>
ErrorLog logs/mysite1.com-error_log
CustomLog logs/mysite1.com-access_log common
</VirtualHost>


<VirtualHost *:80>
ServerAdmin webmaster@mysite2.com
DocumentRoot /var/www/vhosts/mysite2.com/httpdocs/
ServerName mysite2.com
ServerAlias www.mysite2.com
<Directory /var/www/vhosts/mysite2.com/httpdocs/>
AllowOverride all
</Directory>
</VirtualHost>

Thanks.

It sounds like it is most likely treating "unknown" destinations as being part of mysite1.com, the first VirtualHost listed. A fix for this is to create a 'default' vhost, with perhaps ServerName localhost or some other generic thing, and put what you want for unknown destinations in there. Make sure it loads first: if you're using the sites-enabled directory structure, make the file come first in alphabetical order when you do an 'ls'.

Thanks @hoopycat.
It seems to be working fine now...

Here's what the virtual host section of my httpd.conf file now looks like:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html/
ServerName localhost
ServerAlias http://localhost/
<Directory /var/www/html/>
AllowOverride all
</Directory>
ErrorLog logs/localhost-error_log
CustomLog logs/localhost-access_log common
</VirtualHost>

<VirtualHost *:80>
ServerAdmin webmaster@mysite1.com
DocumentRoot /var/www/vhosts/mysite1.com/httpdocs/
ServerName mysite1.com
ServerAlias www.mysite1.com
<Directory /var/www/vhosts/mysite1.com/httpdocs/>
AllowOverride all
</Directory>
ErrorLog logs/mysite1.com-error_log
CustomLog logs/mysite1.com-access_log common
</VirtualHost>

<VirtualHost *:80>
ServerAdmin webmaster@mysite2.com
DocumentRoot /var/www/vhosts/mysite2.com/httpdocs/
ServerName mysite2.com
ServerAlias www.mysite2.com
<Directory /var/www/vhosts/mysite2.com/httpdocs/>
AllowOverride all
</Directory>
</VirtualHost>


However, what did you mean by "if you're using the sites-enabled directory structure, make the file come first in alphabetical order when you do an 'ls'."?

How does that work (i.e a site enabled directory structure)?

Thanks a lot for your help.

Regards,

I don't believe CentOS uses it, so it doesn't apply in this case. Basically, each virtual host would get its own file in a directory called /etc/apache2/sites-available/, and then symlinks are created from /etc/apache2/sites-enabled/ to each of those files. But don't sweat it.
