Section 7.1:Configuring Services on the LVS Routers
7 Initial Configuration
After installing Red Hat Enterprise Linux AS, you must take some basic steps to set up both the LVS
routers and the real servers in the LVS cluster. This chapter reviews these basic steps.
The LVS router node that will become the active node once the cluster is
started is also referred to as the primary node. When configuring an LVS
cluster, use the Piranha Configuration Tool on the primary node.
7.1 Configuring Services on the LVS Routers
The Red Hat Enterprise Linux AS installation program installs all of the components needed to set
up an LVS cluster, but the appropriate services must be activated before configuring the cluster. For
both of the LVS routers, set the appropriate services to start at boot time. There are three primary
tools for setting services to activate at boot time under Red Hat Linux: the command line program
chkconfig, the ncurses-based program ntsysv, or the graphical application serviceconf. All of
these tools require root access.
To attain root access, open a shell prompt and type the following command
followed by the machine's root password:
su -
On the LVS routers, there are at least three services which need to be set to activate at boot time. They
are:
•
The piranha-gui service (primary node only).
•
The pulse service.
•
The sshd service.
If you are clustering multi-port services or using firewall marks, you must also enable either the
ipchains or iptables service, but not both.
