How to configure repos to not overwrite base packages?

CentOS, How to, Linux
The greatest fear with adding additional and especially third party repos such as EPEL (we did a blog post on how to install EPEL earlier) is that it MAY overwrite base packages and bring the system to an unstable state. We can fix this issue by installing Yum Priorities plugin on CentOS 5: [code]yum install yum-priorities[/code] on CentOS 4 or CentOS 6: [code]yum install yum-plugin-priorities[/code] Then make sure that the plugin is enabled [code]nano /etc/yum/pluginconf.d/priorities.conf[/code] Now there are two ways to do it, either set HIGHEST priority to CentOS repos OR set lowest priority to other repos.

Good bye CentOS! Hello Ubuntu

CentOS, Linux, PHP, Reviews, Tips and Tricks, Ubuntu

I tried EPEL repo and it updated PHP to 5.3.1 but still there were conflicts with stuff and many core packages.
