Installing Lighttpd With PHP5 (PHP-FPM) And MySQL Support On Scientific Linux 6.3 - Page 2
5 Configuring Lighttpd And PHP5
To enable PHP5 in Lighttpd, we must modify two files, /etc/php.ini and /etc/lighttpd/lighttpd.conf. First we open /etc/php.ini and uncomment the line cgi.fix_pathinfo=1:
Then we open /etc/lighttpd/modules.conf and uncomment the line include "conf.d/fastcgi.conf":
Next open /etc/lighttpd/conf.d/fastcgi.conf:
There's a fastcgi.server stanza - leave it commented and add your own fastcgi.server stanza as follows:
Then we restart Lighttpd:
6 Testing PHP5 / Getting Details About Your PHP5 Installation
The document root of the default web site is /var/www/lighttpd/. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.
Now we call that file in a browser (e.g. http://192.168.0.100/info.php):
As you see, PHP5 is working, and it's working through FPM/FastCGI, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don't have MySQL support in PHP5 yet.
7 Getting MySQL Support In PHP5
To get MySQL support in PHP, we can install the php-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:
yum search php
Pick the ones you need and install them like this:
yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It's similar to other PHP opcode cachers, such as eAccelerator and Xcache. It is strongly recommended to have one of these installed to speed up your PHP page.
APC can be installed as follows:
yum install php-pecl-apc
Now reload PHP-FPM:
Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules there, including the MySQL module:
8 Making PHP-FPM Use A Unix Socket
By default PHP-FPM is listening on port 9000 on 127.0.0.1. It is also possible to make PHP-FPM use a Unix socket which avoids the TCP overhead. To do this, open /etc/php-fpm.d/www.conf...
... and make the listen line look as follows:
Then reload PHP-FPM:
Next open Lighttpd's PHP configuration file /etc/lighttpd/conf.d/fastcgi.conf and replace the host and port lines with "socket" => "/tmp/php5-fpm.sock":
Finally restart Lighttpd:
