==== Zenoss ====

Our scratch server has been our Zenoss server since the beginning. Ran RHEL 5.5 and is now decommissioned. A new server has been deployed to only do the Zenoss service.  It will run CentOS 6.10 (Final) and Zenoss 4.2.5, specifically the Community Edition last v4 version because I like to keep it simple. All we want is basic monitoring, alerts when nodes go down, and historical data.

<code>

# never understood why
rpm -e --nodeps mysql mysql-server mysql-libs mysql-devel postfix

# autodeploy
mkdir zenoss-deploy
cd zenoss-deploy/
wget https://github.com/zenoss/core-autodeploy/tarball/4.2.5 -O auto.tar.gz
tar zxvf auto.tar.gz
cd zenoss-core-autodeploy-aeb5289/
ls
./core-autodeploy.sh

# boink

</code>

At this point the script fails to find the core rpm file for my distro. Luckily, there are some folks maintaining the script for 4.2.5 and pointing to the new location. Shout out to Jane, much appreciated!

Download the zip file from github.com [[https://github.com/jcurry/Zenoss_4.2.5_core-autodeploy|Zenoss_4.2.5_core-autodeploy]]

<code>

# Stage the maintained autodeploy script

cp /root/Zenoss_4.2.5_core-autodeploy-master.zip .
unzip Zenoss_4.2.5_core-autodeploy-master.zip
ls
cp Zenoss_4.2.5_core-autodeploy-master/core-autodeploy.sh_update_20190110_zenup .
./core-autodeploy.sh_update_20190110_zenup

</code>

Then test out the installation.

You may want to copy the secure_zenoss.sh script and edit it to only keep the Mysql admin password code block to secure your MySQL installation.
