wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz

make top_dir=/usr/lib/httpd/

make top_dir=/usr/lib/httpd/ install



Download and build FastCGI for Apache:

  wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz
  tar -zxf mod_fastcgi-current.tar.gz
  cd mod_fastcgi-2.4.6
  cp Makefile.AP2 Makefile
  make top_dir=/usr/lib64/httpd
Install FastCGI as root:

  make top_dir=/usr/lib64/httpd install
Edit /etc/httpd/conf/httpd.conf and comment out any existing references to PHP you might previously have added for testing:

# LoadModule php5_module        modules/libphp5.so
# AddType application/x-httpd-php .php
Add the php-fpm configuration to httpd.conf:

  LoadModule fastcgi_module modules/mod_fastcgi.so

  <IfModule mod_fastcgi.c>  
    FastCGIExternalServer /usr/sbin/php-fpm -host 127.0.0.1:9000
    AddHandler php-fastcgi .php  

    #<LocationMatch "/status">
    #  SetHandler php-fastcgi-virt
    #  Action php-fastcgi-virt /usr/sbin/php-fpm.fcgi virtual
    #</LocationMatch>

    Action php-fastcgi /usr/sbin/php-fpm.fcgi  
    ScriptAlias /usr/sbin/php-fpm.fcgi /usr/sbin/php-fpm  

    <Directory /usr/sbin>  
      Options ExecCGI FollowSymLinks  
      SetHandler fastcgi-script  
      Order allow,deny  
      Allow from all  
    </Directory>  
  </IfModule> 
Start php-fpm and Apache:

  service php-fpm start
  service httpd start
Test it out with your favorite script or create a file pi.php:

  <?php
    phpinfo();
  ?>
Save it in /var/www/html/pi.php or in $HOME/public_html/pi.php, if you have configured UserDir in httpd.conf.

In a browser load http://localhost/pi.php or http://localhost/~yourname/pi.php.

This will show the PHP configuration values.

To test php-fpm's built-in statistics, edit httpd.conf and uncomment the four lines of the LocationMatch section:

  <LocationMatch "/status">
    SetHandler php-fastcgi-virt
    Action php-fastcgi-virt /usr/sbin/php-fpm.fcgi virtual
  </LocationMatch>
Edit /etc/php-fpm.conf and uncomment the line:

  pm.status_path = /status
Restart php-fpm and Apache:

  service php-fpm restart
  service httpd restart
Run some load on the system:

  ab -c 10 -t 60 http://localhost/pi.php  
Now http://localhost/status gives you the status of the server:

  pool:                 www
  process manager:      dynamic
  start time:           13/Mar/2012:14:25:53 -0700
  start since:          26
  accepted conn:        50001
  listen queue:         0
  max listen queue:     6
  listen queue len:     128
  idle processes:       2
  active processes:     1
  total processes:      3
  max active processes: 5
  max children reached: 1
The php-fpm.conf file documents other output formats for the statistics. It also shows the extensive functionality available with php-fpm.
