PHP 7.0.6 Released

    Debian GNU/Linux installation notes

    This section contains notes and hints specific to installing PHP on » Debian GNU/Linux.

    Warning

    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 apt-get or aptitude commands. This manual page uses these two commands interchangeably.

    Using APT

    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

    Better control of configuration

    In the last section, PHP was installed with only core modules. It's very likely that additional modules will be desired, such as MySQL, cURL, GD, etc. These may also be installed via the apt-get command.

    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 apt-get or 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/apache2/php.ini, /etc/php5/conf.d/pdo.ini, etc. and depending on the extension will add entries similar to extension=foo.so. However, restarting the web server (like Apache) is required before these changes take affect.

    Common Problems

    • If the PHP scripts are not parsing via the web server, then it's likely that PHP was not added to the web server's configuration file, which on Debian may be /etc/apache2/apache2.conf or similar. See the Debian manual for further details.
    • If an extension was seemingly installed yet the functions are undefined, be sure that the appropriate ini file is being loaded and/or the web server was restarted after installation.
    • There are two basic commands for installing packages on Debian (and other linux variants): apt-get and aptitude. However, explaining the subtle differences between these commands goes beyond the scope of this manual.

    To refresh this document, perhaps it would be worth mentioning more modern methods to serve php content under apache httpd.

    Specifically, the preferred method is now fastcgi, using either of those recipes:

    (mod_fastcgi, httpd 2.2)
    http://wiki.apache.org/httpd/php-fastcgi

    (mod_fcgid, httpd 2.2)
    http://wiki.apache.org/httpd/php-fcgid

    (mod_proxy_fcgi, httpd 2.4)
    http://wiki.apache.org/httpd/PHP-FPM

    While the legacy mod_php approach is still applicable for some older installations, the fastcgi method is much faster, and require much less RAM to operate, based on similar traffic patterns.

    Thank you!

    To install LAMP stack on Ubuntu (+Server) from 10.04 you need first install taskel and then lamp-server for example:

    Install taskel, follow terminal guides:
    sudo apt-get install tasksel

    Install LAMP stack package from Ubuntu repository:
    sudo tasksel install lamp-server

    sudo tasksel install lamp-server

    With Apache2 and Php4 under Debian Sarge there is an extra configuration file :  /etc/apache2/sites-available/default
    This file is not clearly documented, at least not for noobs, in Apache docs.

    It overrides the conf file in the way you expect the /etc/apache2/conf.d/apache2-doc  to do according to the README.

    Add ExecCGI to it to get rid of "Options ExecCGI is off in this directory"  errors.

    then restart the computer/start mysql manually
