This section contains notes and hints specific to installing PHP on » Debian GNU/Linux.
Unofficial builds from third-parties are not supported here. Any bugs should be reported to the Debian team unless they can be reproduced using the latest builds from our » download area.
While the instructions for building PHP on Unix apply to Debian as well,
this manual page contains specific information for other options, such as
using either the
commands. This manual page uses these two commands interchangeably.
First, note that other related packages may be desired like
libapache2-mod-php5 to integrate with Apache 2, and
php-pear for PEAR.
Second, before installing a package, it's wise to ensure the package list is up to date. Typically, this is done by running the command apt-get update.
Example #1 Debian Install Example with Apache 2
# apt-get install php5-common libapache2-mod-php5 php5-cli
APT will automatically install the PHP 5 module for Apache 2 and all of its dependencies, and then activate it. Apache should be restarted in order for the changes take place. For example:
Example #2 Stopping and starting Apache once PHP is installed
# /etc/init.d/apache2 stop # /etc/init.d/apache2 start
In the last section, PHP was installed with only core modules. It's
very likely that additional modules will be desired, such as
etc. These may also be installed via the
Example #3 Methods for listing additional PHP 5 packages
# apt-cache search php5 # aptitude search php5 # aptitude search php5 |grep -i mysql
The examples will show a lot of packages including several PHP specific ones
like php5-cgi, php5-cli and php5-dev. Determine which are needed
and install them like any other with either
aptitude. And because Debian performs
dependency checks, it'll prompt for those so for example to install
MySQL and cURL:
Example #4 Install PHP with MySQL, cURL
# apt-get install php5-mysql php5-curl
APT will automatically add the appropriate lines to the
different php.ini related files like
/etc/php5/conf.d/pdo.ini, etc. and depending on
the extension will add entries similar to
However, restarting the web server (like Apache) is required before these
changes take affect.
aptitude. However, explaining the subtle differences between these commands goes beyond the scope of this manual.
