Using Apache with PHP4 and PHP5 at the same time
This is an example showing how you can run apache with php4 and php5 at the same time, on the same machine.
People ask me how to run apache with php4 and php5 at the same time. Well, it generally can't be done because the mod_php[45] modules will conflict internally (symbol clashes). The trick is to run apache in a second instance on a different port or using dedicated ip addresses for each apache instance. To do this you need to get root and do some manual tasks outlined below:
# urpmi apache-mod_php4 # mv /etc/httpd/modules.d/70_mod_php4.conf /etc/httpd/conf/ # ln -s /usr/sbin/httpd /usr/sbin/httpd-php4 # cp -p /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd-php4.conf
Apply these changes to the new httpd-php4.conf file:
--- httpd.conf 2005-08-30 06:25:31.000000000 +0200
+++ httpd-php4.conf 2005-09-22 12:58:04.000000000 +0200
