The simplest way to install Zenoss Core 4.2 on a newly-deployed RHEL/CentOS 64-bit 5/6 system is to use our auto-deploy script, which downloads all required files for you.
Register and download
# wget –no-check-certificate https://github.com/zenoss/core-autodeploy/tarball/4.2.4 -O auto.tar.gz
# tar xvf auto.tar.gz
# cd zenoss-core-autodeploy-*
Now, you have the option of editing zenpack_actions.txt, which defines all ZenPacks that will be installed by default (all Core ZenPacks). If you would like to avoid installing certain ZenPacks, then remove the corresponding lines from this file and save it.
As part of the install process, your Zenoss installation will be secured, and you will be asked if you would like to set a secure root password for MySQL. It is strongly recommended that you do so.
The auto-deploy script will automatically download and install all required dependencies, as well as Zenoss Core 4.2. After the script completes successfully, use your favorite Web browser and head to port 8080 of your new server (for example, http://127.0.0.1:8080), and then set the Zenoss administrator password and create your initial user account using the Web interface.
The Installation Guide will guide you through the process of installing Zenoss Core 4.2 on a 64-bit version of Red Hat Enterprise Linux 5.x or 6.x, using RPMs that you download from SourceForge
