I need to install php as cgi like in the first picture under ubuntu, but i've tried many different things to no avail.

I have system 1 (pic 1) which is working perfectly and need to configure system 2 (pic 2) to be exactly the same.

The system configurations are attached as images.

I'm guessing, you wish to use FastCGI. First, you need to select your FCGI handler. Either mod_fastcgi or mod_fcgid. Then, create a wrapper script for the php-cgi process to set some nice parameters like the php.ini location. If you want to use suexec, you need to let the user own the wrapper script you want it to run as. You should see the Apache suexec documentation for this. Next, configure your webserver to use the FastCGI version for PHP. Depending on which module you chose, this might look different.

Yes I think this is what I want, and suexec as well as I need users to be able to run under their users.
Thing is however, I have no idea how to do this.

Fcgid is already enabled via a2enmod fcgid.

But don't know how to do the rest.

Well, you're going to have to read the docs. There are plenty of tutorials out there, just google for "mod_fcgid tutorial" and find sites like this one.

Ok i followed this tutorial.

I followed most of it exactly but my document roots are in /home/[username]/public_html

Everything worked fine until i try to go to phpmyadmin via domain.com/phpmyadmin, which then shows whats in pic1.png. If i do domain.com/phpmyadmin/index.php it works fine.

the vhosts file looks like so:

<VirtualHost 192.168.0.60:80>
ServerName domain.com
ServerAlias www.domain.com
ServerAdmin admin@domain.com
DocumentRoot /home/adhocrac/public_html/

<IfModule mod_fcgid.c>
SuexecUserGroup adhocrac adhocrac
PHP_Fix_Pathinfo_Enable 1
<Directory /home/adhocrac/public_html/>
Options +ExecCGI
AllowOverride All
AddHandler fcgid-script .php
FCGIWrapper /var/www/fcgi/adhocrac/fcgi-starter .php
Order allow,deny
Allow from all
</Directory>
</IfModule>

# ErrorLog /var/log/apache2/error.log
# CustomLog /var/log/apache2/access.log combined
ServerSignature Off

Alias /explorer /home/adhocrac/explorer
<IfModule mod_fcgid.c>
SuexecUserGroup adhocrac adhocrac
PHP_Fix_Pathinfo_Enable 1
<Directory /home/adhocrac/explorer>
Options +ExecCGI

AddHandler fcgid-script .php
FCGIWrapper /var/www/fcgi/adhocrac/fcgi-starter .php
Order allow,deny
Allow from all
</Directory>
</IfModule>
</VirtualHost>

The hostname of the server is host.foo.com and if i go to host.foo.com/phpmyadmin, it works fine. The vhosts file for host.foo.com looks like:

<VirtualHost 192.168.0.60:80>
ServerName host.foo.com
ServerAdmin admin@foo.com
DocumentRoot /home/rackelas/public_html/

<IfModule mod_fcgid.c>
SuexecUserGroup rackelas rackelas
PHP_Fix_Pathinfo_Enable 1
<Directory /home/rackelas/public_html/>
Options +ExecCGI
AllowOverride All
AddHandler fcgid-script .php
FCGIWrapper /var/www/fcgi/rackelas/fcgi-starter .php
Order allow,deny
Allow from all
</Directory>
</IfModule>

# ErrorLog /var/log/apache2/error.log
# CustomLog /var/log/apache2/access.log combined
ServerSignature Off

</VirtualHost>

I can't figure out why this is happening, any help is appreciated.

SOLVED, i restarted the server and now it works.
