Running Apache2 With PHP5 And PHP4 At The Same Time - Page 2

2 Setup For Ubuntu 5.10 (Breezy Badger)

This setup does not differ much from the one for Debian Sarge.

First, you must at least have a working basic Ubuntu 5.10 installation, as described on the first two pages of the "Perfect Setup" tutorial for Ubuntu 5.10 "Breezy Badger" here on HowtoForge: and

The official Ubuntu repositories contain packages for both PHP5 and PHP4 so we don't have to use third-party repositories. However, make sure /etc/apt/sources.list looks like this:

deb breezy main restricted
deb-src breezy main restricted

deb breezy-updates main restricted
deb-src breezy-updates main restricted

deb breezy universe
deb-src breezy universe

deb breezy-security main restricted
deb-src breezy-security main restricted

deb breezy-security universe
deb-src breezy-security universe


apt-get update

after you've changed /etc/apt/sources.list.

Now we can install Apache2 as well as the Apache2-PHP5 module and the PHP4-CGI:

apt-get install apache2 apache2-common apache2-doc apache2-mpm-prefork apache2-utils libapr0 libexpat1 ssl-cert
apt-get install libapache2-mod-php5 php4-cgi

Next, we can install all the PHP5 and PHP4 modules we need on our server, like this:

apt-get install php5-imap php5-syck php-pear php5-curl php5-dev php5-gd php5-ldap php5-mhash php5-mysql php5-odbc php5-recode php5-snmp php5-sqlite php5-xmlrpc php5-xsl php4-auth-pam php4-imagick php4-mcrypt php4-rrdtool php4-sqlite php4-curl php4-domxml php4-gd php4-imap php4-ldap php4-mcal php4-mhash php4-mysql php4-odbc php4-pear php4-xslt (1 line!)

Edit /etc/apache2/apache2.conf. Change

DirectoryIndex index.html index.cgi index.php index.xhtml


DirectoryIndex index.html index.htm index.shtml index.cgi index.php index.php4 index.xhtml

and add these two lines as well (in the section where you can find AddType and AddHandler directives):

AddHandler php-script .php4
Action php-script /cgi-bin/php4

This will make sure that PHP files with the extension .php4 are executed as CGI. PHP files with the extension .php will be run by the Apache2-PHP5 module.

Next, we have to enable a few Apache modules, like for example the actions module (otherwise we cannot run PHP4 as CGI):

a2enmod actions
a2enmod ssl
a2enmod rewrite
a2enmod suexec
a2enmod include

Restart Apache, and you're done!

/etc/init.d/apache2 restart

Now we can test our installation: Put two files, info.php and info.php4, with the same content:


into /var/www (this is the default document root of Ubuntu's Apache2) and try to access them in a browser (if the server's IP address is, for example, you would type and You should see two different PHP versions, one run as Apache module (PHP5), the other one (PHP4) called as CGI:
