Auto installation of Zenoss on CentOS 6

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. To use the script, first set up a new server running one of our supported operating systems. Then, as root, run the following commands:

# wget https://github.com/zenoss/core-autodeploy/tarball/4.2.5 -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.

Now you are ready to install Zenoss Core 4.2.5:

# ./core-autodeploy.sh #do not use ''tee'' or similar, /opt/zenoss/log/install.log will be created by the script.
