Zenoss Notes

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:

Port	Protocol	Description
8080	HTTP	Zenoss Web Interface
514	UDP	Inbound syslog
162	UDP	Inbound SNMP Traps

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
```
zopeurl      http://servername.tld:9090
```
