2.4. Remove Outdated Packages
Zenoss Core requires at least MySQL 5.5.25, and supports later versions through 5.5.35. If you have older versions of
MySQL installed, you must first remove those installations. Current data will be lost.
1. Stop the MySQL service:
service mysqld stop
2. List the MySQL packages currently installed:
rpm -qa | grep -i mysql
3. Remove all listed packages:
yum erase Package1 Package2 ...
4. If your version of MySQL is earlier than 5.5.25, delete the MySQL directory:
rm -rf /var/lib/mysql
If your version of MySQL is 5.5.25 or a more recent version, DO NOT delete the MySQL directory.
2.5. Remove Conflicting Messaging Systems
Zenoss Core relies on the RabbitMQ messaging system. Newer versions of CentOS include alternative messaging
systems (Matahari and Qpid). You must remove these messaging systems to run Zenoss Core.
1. Use the following commands to determine if Matahari or Qpid packages are installed on your system:
rpm -qa | egrep -i "matahari|qpid"
2. Remove all listed packages:
yum erase Package1 Package2 ...
2.6. Install Oracle Java
Install Oracle Java 1.6. (Java 1.7 is not supported.)
