I have this error on Debian Wheezy, I don't understand what am I missing. Logs from php5-fpm are OK.

Error from apache2 log:

in pool.d/www.conf, take note of

listen = /var/run/www.sock

in php5-fpm.conf, on this line:

FastCGIExternalServer /var/lib/apache2/fastcgi/php5.fastcgi -socket /var/run/php5-fpm.sock -idle-timeout 610

/var/run/php5-fpm.sock must be the same as the listen option in pool.d/www.conf

In VHost www :

FastCgiExternalServer /home/web/xxxx/www/cgi-bin/php5.external -idle-timeout 310 -flush -socket /var/run/www.sock

This line is useless without

Alias /php5.external /home/web/xxxx/www/cgi-bin/php5.external
Action php-script /php5.external virtual

Hope this help.

You can read about this here: http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html#FastCgiExternalServer

I'm assuming that you want to run each vhost as a different user/group. Otherwise you need only of them practically anywhere in your conf files (Could be in fastcgi.conf). For that, check out this url:

http://www.versatilewebsolutions.com/blog/2012/11/installing-apache-2-with-php-fastcgi-on-ubuntu-12-10.html

For the run as user thing, I'll try to explain how this works:

I don't think you have to touch php-fpm.conf, just leave it be like it is when you installed php5-fpm Without comments mine looks like this:

php-fpm.conf

[global]

pid = /var/run/php5-fpm.pid
error_log = /var/log/php5-fpm.log
include=/etc/php5/fpm/pool.d/*.conf

You seem to have one virtual host, so I don't know what you would do with 2 fastcgiexternalservers anyway.

The steps the php is squeezed through are the following:

  1. AddHandler php-script .php
  2. Action php-script /php5.fastcgi
  3. Alias /php5.fastcgi /var/lib/apache2/fastcgi/php5.fastcgi
  4. FastCgiExternalServer /var/lib/apache2/fastcgi/php5.fastcgi -socket php5-fpm.sock

Here at #4, the alias given at #3 will be resolved by the fastcgiexternalserver (the path does not have to exist), and the socket parameter is a filename relative to the FastCgiIpcDir you defined earlier. I'm using currently the following directory for that: 

FastCgiIpcDir  /var/run/

Which will mean that your journey continues at /etc/php5/fpm/pool.d/www.conf

The important row is:

listen = /var/run/php5-fpm.sock

The path has to be the same as fastcgiipcdir plus the relative socketname, so the flow will be picked up here. Without comments:

www.conf

[www]
user = www-data
group = www-data

listen = /var/run/php5-fpm.sock

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

chdir = /

For each socket (for each site if each socket is different) you want to listen to, you have to create new conf files (like www.conf). The four steps I described earlier should be in each virtual host that you want to run as other user/group. I believe it should look like this:

Vhost www

<VirtualHost *:80>
  ServerName xxxx.com

  ServerAdmin [email protected]
  DocumentRoot /home/web/xxxx/www/prod
  Options None

  AddHandler php-script .php
  Action php-script /php5.fastcgi
  Alias /php5.fastcgi /var/lib/apache2/fastcgi/php5.fastcgi
  FastCgiExternalServer /var/lib/apache2/fastcgi/php5.fastcgi -socket php5-fpm.sock


 <Directory /home/web/xxxx/www/prod/>
    Options Indexes FollowSymLinks Includes
    AllowOverride None
    Order allow,deny
    Allow from all
  </Directory>

  ErrorLog /var/log/apache2/error.www_prod.log
  LogLevel debug
  CustomLog /var/log/apache2/access.www_prod combined
</VirtualHost>

After this, always make sure to give write access where the sockets will be created. That would be the fastcgiipcdir /var/run for me on ubuntu, which points to /run, so I just chmodded that:

chmod 777 /run

(Of course that's not very nice to do, but for demonstration and local testing it's fine)

Enable your site:

a2ensite site  //site: just whatever your www vhost conf file name is

And when you want to try it out, always restart both php-fpm and apache :

service php5-fpm restart
service apache2 restart

Try to understand these first, then making it work will be a piece of cake. I had my share of trying lots of different combinations but when I understood it, it made sense.
