Zenoss Notes Revision as of Friday, 4 June 2021 at 03:52 UTC

Pre-Flight

• SNMP uses UDP on port 161
• Zenoss provides a lot of useful
  documentation.
• The following ports need to be allowed to the server:

Installation

Zenoss Server

Note: Zenoss does not like special characters in the MySQL root
password.

# Install necessary packages; MySQL and net-snmp are required  
yum -y install mysql-server net-snmp net-snmp-utils gmp libgomp libgcj liberation-fonts  
  
# Configure MySQL  
  
# Install Zenoss  
mkdir zenoss.temp; cd zenoss.temp  
wget http://downloads.sourceforge.net/zenoss/zenoss-3.2.0.el5.i386.rpm
rpm -ivh zenoss-3.2.0.el5.i386.rpm  
service zenoss start

This sets up everything. Go get some tea; this shall take a
while. Then navigate to http://<FQDN>:8080 to finish setup. This
book
is your friend, friend.

Uninstallation

Navigate to the directory where Zenoss was installed.

[root@zenoss zenoss]# ./uninstall

Miscellaneous

• Edit /opt/zenoss/etc/zope.conf and edit the address under <http-server>.

• Don’t change the default directory (/usr/local/zenoss)

• Changed zSnmpVer to v2c under “Configuration Properties” for Device Class

• Reinstalled Zenoss for HDD monitoring

• A most excellent overview of SNMP.
  This is probably all you need to get started.

• Change admin password like so:

  su - zenoss  
  /usr/local/zenoss/zenoss/bin/zenpass
  

• If you have a non-default port, your email alerts will still use the
  default (8080). To change this, edit $ZENHOME/etc/zenactions.conf,
  add a line like so, and restart Zenoss
