Installing Lighttpd With PHP5 And MySQL Support On Ubuntu 10.10 - Page 2

5 Configuring Lighttpd And PHP5

To enable PHP5 in Lighttpd, we must modify /etc/php5/cgi/php.ini and uncomment the line cgi.fix_pathinfo = 1:

vi /etc/php5/cgi/php.ini
[...]
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; http://php.net/cgi.fix-pathinfo
cgi.fix_pathinfo=1
[...]

To enable the fastcgi configuration, run the following commands:

lighttpd-enable-mod fastcgi
lighttpd-enable-mod fastcgi-php

This creates the symlinks /etc/lighttpd/conf-enabled/10-fastcgi.conf which points to /etc/lighttpd/conf-available/10-fastcgi.conf and /etc/lighttpd/conf-enabled/15-fastcgi-php.conf which points to /etc/lighttpd/conf-available/15-fastcgi-php.conf:

ls -l /etc/lighttpd/conf-enabled
root@server1:/etc/lighttpd/conf-available# ls -l /etc/lighttpd/conf-enabled
total 0
lrwxrwxrwx 1 root root 44 2010-10-28 13:45 10-fastcgi.conf -> /etc/lighttpd/conf-available/10-fastcgi.conf
lrwxrwxrwx 1 root root 48 2010-10-28 16:00 15-fastcgi-php.conf -> /etc/lighttpd/conf-available/15-fastcgi-php.conf
root@server1:/etc/lighttpd/conf-available#

Then we reload Lighttpd:

/etc/init.d/lighttpd force-reload

 

6 Testing PHP5 / Getting Details About Your PHP5 Installation

The document root of the default web site is /var/www. 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.

vi /var/www/info.php
<?php
phpinfo();
?>

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 php5-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:

aptitude search php5

Pick the ones you need and install them like this:

aptitude install php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-json

Now restart Lighttpd:

/etc/init.d/lighttpd restart

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:
