How to fix SCRIPT_NAME with PHP-FPM and Apache’s mod_fastcgi

apache-2.2php-fpm

I have the following in my Apache conf to get PHP-FPM working:

FastCgiExternalServer /srv/www/fast-cgi-fake-handler -host 127.0.0.1:9000
AddHandler php-fastcgi .php
AddType text/html .php
Action php-fastcgi /var/www/cgi-bin
Alias /var/www/cgi-bin /srv/www/fast-cgi-fake-handler
DirectoryIndex index.php

This works fine except that SCRIPT_NAME is always /var/www/cgi-bin and some scripts use SCRIPT_NAME to work out the location of the current script (vBulletin).

Google has plenty of solutions for Nginx but not a word for Apache.

If you use RewriteRule in place of "Action" method, it will work out just fine

Given below is an example I used to in Apache to connect to FCGI::Daemon external fastcgi daemon process. This daemon can be considered as a perl's version of php-fpm.

<VirtualHost 127.0.0.1:80>
    ServerAdmin info@example.com
    DocumentRoot "/var/www/example"
    ServerName www.example.com

    <IfModule mod_fastcgi.c>
    FastCGIExternalServer /var/www/fcgi-daemon/perl.fcgi -socket /var/run/fcgi-daemon.sock
    ScriptAlias /perl.fcgi /var/www/fcgi-daemon/perl.fcgi
    </IfModule>
</VirtualHost>

<Directory /var/www/example/cgi-bin>
    Options ExecCGI
    RewriteRule ^(.*)$ /perl.fcgi [L]
</Directory>

Note: "/var/www/fcgi-daemon/" has to exist! as blank directory. Actual the method you used for php does not work out of box for perl daemon. SCRIPT_FILENAME was always /var/www/fcgi-daemon/perl.fcgi which never existed, leading to error. Using RewriteRule kept all the required environment variables in place and passed them along to perl fastcgi daemon.

By default the Nginx source does not define SCRIPT_FILENAME in the fastcgi_params file, so unless the repo you installed Nginx from does that you need to do it yourself.

Check if the following line is in your fastcgi_params file:

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

and if not then add it.

Php – How to set the httpd.conf when using php-fpm with php(5.3.8) and apache2

The secret here is that php-cgi is nto a real file, it's a wrong file name use internally in Apache. You could call it as well : false-php-cgi-catcher-which-do-not-exists.

I wrote a complete php-fpm+apache2.2+chroot install guide a few days ago here. You may have a look. But try to get it working without the chroot first. Note that starting with apache 2.3 the best tool for php-fpm will be mod_proxy_fcgi

Here's an extract of the complete install guide. I use php5.external where you want to use php-cgi.

# phpfpm/fastcgi
# Here we catch the 'false' Location used to inexistent php5.external
# and push it to the external FastCgi process via a socket
# note: socket path is relative to FastCgiIpcDir
# which is set in Main configuration /etc/apache2/mods-available/fastcgi.conf
<IfModule mod_fastcgi.c>
    # all .php files will be pushed to a php5-fcgi handler
    AddHandler php5-fcgi .php

    #action module will let us run a cgi script based on handler php5-fcgi
    Action php5-fcgi /fcgi-bin/php5.external

    # and we add an Alias to the fcgi location
    Alias /fcgi-bin/php5.external /php5.external

    # now we catch this cgi script which in fact does not exists on filesystem
    # we catch it on the url (Location)
    <Location /fcgi-bin/php5.external>
        # here we prevent direct access to this Location url,
        # env=REDIRECT_STATUS will let us use this fcgi-bin url
        # only after an internal redirect (by Action upper)
        Order Deny,Allow
        Deny from All
        Allow from env=REDIRECT_STATUS
    </Location>
</IfModule>
FastCgiExternalServer /php5.external -socket myapplication.sock -appConnTimeout 30 -idle-timeout 60
