How to set up a PHP4 / MySQL4 environment on Ubuntu

Install Dapper Drake (6.06.2 LTS) server NOT the LAMP.  This is the last release supporting the 4.x environment unless you compile all the source yourself on Feisty or Hardy.

Enable the universe repository in /etc/apt/sources.list by uncommenting

deb http://us.archive.ubuntu.com/ubuntu/ dapper universe
deb-src http://us.archive.ubuntu.com/ubuntu/ dapper universe

Comment out the cdrom repository if you want to avoid prompts about getting packages from it.

#deb cdrom:[Ubuntu-Server 6.06.2 _Dapper Drake_ - Release i386 (20080110.1)]/ dapper main restricted

Install php4

apt-get install php4

Install MySql 4.1

apt-get install mysql-server-4.1

Install the php4 support for mysql

apt-get install php4-mysql

Note: It shows the Client API version as 5.0.22  but it seems to work OK.
