Installing Zenoss:

1.1. Prerequisite Tasks

Note

Run all commands as root, from the machine where you want to install Zenoss.

Before you install:

1. Run the Yellowdog Updater, Modified (YUM), which you will use to install Zenoss. To run YUM, enter this

command:

# yum -y install mysql-server net-snmp net-snmp-utils gmp libgomp libgcj liberation-fonts

2. Download the Zenoss installation files.

3. If you have just installed MySQL, then use the following commands to adjust the permissions:

# /etc/init.d/mysqld restart

# /usr/bin/mysqladmin -u root password ''

# /usr/bin/mysqladmin -u root -h YOUR_SERVER_NAME password ''

Note

Initially, the MySQL password must be blank so that Zenoss can correctly create the database. After you

have installed and started Zenoss, you can change this password.

If MySQL is running on a different server, or has a different root user password, edit the /opt/zenoss/

bin/zenoss_init_pre file and adjust the MYSQLHOST, MYSQLROOTUSER, and MYSQLROOTPASSWD

values.

3. Enter this command to start Zenoss.

# service zenoss start
