After installing the necessary mod_cluster components in httpd, we will configure them properly in this section.
Before we start to configure mod_cluster, we need to do some preparations in httpd.conf
. The first thing to do is to change the Listen
directive from Listen 80
to the following:
Listen 10.0.1.33:80 Listen 10.0.1.33:6666 Listen 172.16.123.1:80
As we know, lb has two IP addresses: one is the public address 172.16.123.1, and the other is 10.0.1.33, which is the internal IP address of the load balancer used to communicate with the two EAP6 servers. Now let's learn the purpose of the configuration:
10.0.1.33:80
will be used for a mod_cluster management console. We don't want public access of this management console, so we just bind it to the local IP address.10.0.1.33:6666
will be used by mod_manager to communicate with the EAP6 servers, and the message encapsulated in the MCPM protocol will be transferred through this channel.172.16.123...
