Here is getting Zenoss 4 up and running on CentOS 6 server. This guide was originally tested on a freshly patched CentOS 6.3 on August 12, 2012. Zenoss 4.2 was the current version of Zenoss.
two types of installation.
1.Auto Deploy
There is a nice auto install script available now - it is recommended you use this method on a new install. Example is for Zenoss 4.2.4 - always check the Zenoss site for new versions before starting.

# 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-*
# ./core-autodeploy.sh Navigate to your server using a web browser: http://server-ip:8080
2.Manual Way
Install EPEL repos.
Disable iptables (or configure it - see Firewall Ports)
rpm -ivh http://fedora.mirror.nexicom.net/epel/6/i386/epel-release-6-8.noarch.rpmDisable SELinux (or configure it properly)
yum check-update
Disable iptables (or configure it - see Firewall Ports)
Procedure
1. Setup /home/zenoss directory.
Oracle Java → 1.6 Update 31 or later. 1.7 is NOT supported. The one in yum is 1.5.x. DO NOT use this version. Get 1.6.
Download the following:
Add the following to /etc/my.cnf (create if not already existing)
A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER ! You will find that password in '/root/.mysql_secret'.
Then you will need to check the /root/.mysql_secret file for the current password. This appears to be fairly new behaviour (MySQL-server.x86_64 0:5.6.11-1.el6 )
Configure blank root password for the Zenoss installer (add the -p option to be prompted for password if you find that a password was generated for you during first mysql start):
6. Download the latest version of ZenOSS to your server. Current in example is 4.2.
10. Install Zenpacks:
useradd -m -d /home/zenoss -c "Zenoss User" zenoss2. Remove conflicting packages

rpm -qa | grep -i matahari3. Remove Old Mysql - if any:
rpm -qa | grep -i qpid
rpm -e --nodeps <package>
service mysql stop4. Install / Update prerequisites:
rpm -qa | grep -i mysql
rpm -e --nodeps <package>

chkconfig --add mysql
chkconfig --level 2345 mysql on
A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER ! You will find that password in '/root/.mysql_secret'.
Then you will need to check the /root/.mysql_secret file for the current password. This appears to be fairly new behaviour (MySQL-server.x86_64 0:5.6.11-1.el6 )
Configure blank root password for the Zenoss installer (add the -p option to be prompted for password if you find that a password was generated for you during first mysql start):
mysqladmin -u root password ''RabbitMQ → 2.8.4 or later.
mysqladmin -u root -h localhost password ''
wget http://www.rabbitmq.com/releases/rabbitmq-server/v2.8.4/rabbitmq-server-2.8.4-1.noarch.rpmNagios Plugins → 1.4.15 or later.

6. Download the latest version of ZenOSS to your server. Current in example is 4.2.
wget http://sourceforge.net/projects/zenoss/files/zenoss-4.2/zenoss-4.2.0/zenoss-4.2.0.el6.x86_64.rpm/download7. Fire up the last few services:
yum -y --enablerepo=epel --nogpgcheck localinstall zenoss-4.2.0.el6.x86_64.rpm
service memcached start8. Start up Zenoss - watch for errors or complaints.
chkconfig memcached on

chkconfig snmpd on
service zenoss start9. Hit the Zenoss WebGUI at <serverip>:8080 and finish walking through the wizard to complete the install.
10. Install Zenpacks:
wget http://sourceforge.net/projects/zenoss/files/zenpacks-4.2/zenpacks-4.2.0/zenoss-core-zenpacks-4.2.0.el6.x86_64.rpm11. Next fine tune your Zenoss installation. See Performance Tuning section.
yum -y --nogpgcheck localinstall zenoss-core-zenpacks-4.2.0.el6.x86_64.rpm
Errors
Symlinking /usr to /local/usr or something of that nature breaks zenoss startup script.
service zenoss start
env: /etc/init.d/zenoss: No such file or directory
No skip to dashboard button off install.
Rebooted server. Fixed it - there were no errors during install when this happened.
