This chapter provides information about some useful extra steps or adjustments you might want to perform before you start installing or upgrading Panel.
Install Panel with Packages from Alternative Repositories (CentOS Only)
In Panel 10.2 and earlier versions, Parallels Installer fetched the packages required for Panel installation or upgrade from the Parallels Updates server. This server also contained upgrades to these packages. Hence, there was no way to use custom package versions when installing or upgrading Panel. In 10.3 you do have this option if you tune the Installer configuration.
The tuned Installer works this way: It checks that you have the
yum package manager and that it is configured to use alternative repositories. If these check-ups succeed, the Installer uses the latest versions of packages it finds in all available repositories when installing or upgrading Panel. For example, if Parallels Updates contains MySQL v.5.0.84, and the other repository (say, IUS) contains MySQL v.5.0.93, the most current version (5.0.93) will be installed.
To turn this feature on, edit the
/root/.autoinstallerrc file by adding the USE_YUM='yes' line to it.
