Installing PHP

Install PHP using yum.

yum install lighttpd-fastcgi php-fpm

Configure PHP-FPM user settings.

vi /etc/php-fpm.d/www.conf

We must add the following lines to the either the top or bottom of the configuration:

user = lighttpd

group = lighttpd

Make PHP-FPM start on boot.

php-fpm on

Start PHP-FPM.

service php-fpm start

Configure php.ini.

vi /etc/php.ini

Remove the commenting on the following line.

cgi.fix_pathinfo=1

Tell Lighttpd that PHP exists on this server.

vi /etc/lighttpd/modules.conf

Add the following line.

include “conf.d/fastcgi.conf”

Now we must tell PHP to listen on port 9000 (Lighttpd will send PHP requests there). Using your favorite text editor, edit the fastcgi configuration.

vi /etc/lighttpd/conf.d/fastcgi.conf

At the top of the configuration, add the following lines of code.

fastcgi.server += ( “.php” =>

((

“host” => “127.0.0.1″,

“port” => “9000″,

“broken-scriptfilename” => “enable”

))

)

Restart PHP-FPM and Lighttpd for our changes to take effect.

service php-fpm restart

service lighttpd restart
