Installing Lighttpd With PHP5 And MySQL Support On CentOS 6.0 - 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 add the line cgi.fix_pathinfo = 1 right at the end of the file:
Then we open /etc/lighttpd/modules.conf and uncomment the line include "conf.d/fastcgi.conf":
Next open /etc/lighttpd/conf.d/fastcgi.conf...
... and uncomment the fastcgi.server stanza - make sure you change the socket lines to /tmp/php-fastcgi-1.socket and /tmp/php-fastcgi-2.socket, and both bin-path lines must have the value /usr/bin/php-cgi:
Then we restart Lighttpd:
6 Testing PHP5 / Getting Details About Your PHP5 Installation
The document root of the default web site is /srv/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 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
Now restart Lighttpd:
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:
