Php – Apache 2.4 + PHP-FPM + mod_fastcgi (Problems setting up PHP-FPM)

apache-2.4fastcgimod-fastcgiPHPphp-fpm

I have been trying to get PHP-FPM to work with Apache 2.4, but mod_fastcgi does not work with 2.4. Is there any solution to this problem? I want to run it using an UNIX socket, but I cannot find any tutorial on this, they all use 127.0.0.1:9000

I installed Apache 2.2 with mod_fastcgi and it works using UNIX sockets.

Snippet of configuration from my httpd.conf is:

<IfDefine FASTCGI>
    <IfModule mod_fastcgi.c>
        Alias                   /php5.fastcgi /var/www/example.com/cgi-bin/php5.fastcgi
        FastCGIExternalServer   /var/www/example.com/cgi-bin/php5.fastcgi -flush -socket /var/www/example.com/php-fpm.sock -idle-timeout 30
        AddType                 application/x-httpd-fastphp5    .php
        Action                  application/x-httpd-fastphp5    /php5.fastcgi

        DirectoryIndex index.php index.html
    </IfModule>
</IfDefine>

PHP-FPM is listening on socket /var/www/example.com/php-fpm.sock.

PHP-FPM's configuration (inside a pool):

listen          = /var/www/$pool/php-fpm.sock
listen.owner    = apache
listen.group    = apache
listen.mode     = 0660

I did not succeed with mod_fcgi. Apache 2.4 now has mod_proxy_fcgi which I didn't tested. You need something with that can work with external FastCGI servers and don't manage the processes itself.

Apache PHP-FPM – Managing Multiple PHP-FPM Pools

The trick is that you need to rename the action and alias too so they are not 'redefinitions', so for my 'www' pool, my vhost config looks like this:

<IfModule mod_fastcgi.c>
    <FilesMatch \.php$>
        SetHandler php-script
    </FilesMatch>
    Action php-script /php5-www.fcgi virtual
    Alias /php5-www.fcgi /var/fastcgi/php5-www.fcgi
    FastCGIExternalServer /var/fastcgi/php5-www.fcgi -socket /var/run/php5-fpm-www.sock
    <Directory "/var/fastcgi">
        Order allow,deny
        <Files "php5-www.fcgi">
            Order deny,allow
            Deny from all
            Allow from env=REDIRECT_STATUS
        </Files>
    </Directory>
</IfModule>

And for SSL on the same pool:

<IfModule mod_fastcgi.c>
    <FilesMatch \.php$>
        SetHandler php-script
    </FilesMatch>
    Action php-script /php5-www-ssl.fcgi virtual
    Alias /php5-www-ssl.fcgi /var/fastcgi/php5-www-ssl.fcgi
    FastCGIExternalServer /var/fastcgi/php5-www-ssl.fcgi -socket /var/run/php5-fpm-www.sock
    <Directory "/var/fastcgi">
        Order allow,deny
        <Files "php5-www-ssl.fcgi">
            Order deny,allow
            Deny from all
            Allow from env=REDIRECT_STATUS
        </Files>
    </Directory>
</IfModule>

So they're using different names, but pointing at the same socket.

Apache PHP-FPM – Configure Apache 2.4 with PHP-FPM and ProxyPassMatch

After hours of searching and reading Apache documentation I've come up with a solution that allows to use the pool, and also allow the Rewrite directive in .htaccess to work even when the url contains .php files.

<VirtualHost ...>

 ...

 # This is to forward all PHP to php-fpm.
 <FilesMatch \.php$>
   SetHandler "proxy:unix:/path/to/socket.sock|fcgi://unique-domain-name-string/"
 </FilesMatch>

 # Set some proxy properties (the string "unique-domain-name-string" should match
 # the one set in the FilesMatch directive.
 <Proxy fcgi://unique-domain-name-string>
   ProxySet connectiontimeout=5 timeout=240
 </Proxy>

 # If the php file doesn't exist, disable the proxy handler.
 # This will allow .htaccess rewrite rules to work and 
 # the client will see the default 404 page of Apache
 RewriteCond %{REQUEST_FILENAME} \.php$
 RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_URI} !-f
 RewriteRule (.*) - [H=text/html]

</VirtualHost>

As per Apache documentation, the SetHandler proxy parameter requires Apache HTTP Server 2.4.10.

I hope that this solution will help you too.
