Hey Guys,
The OS am running is CentOS 6.4 (64bit) and I have disabled IPtables and
SeLinux.
My goal is to make Apache Tomcat as HA. As a first step thought of testing
with Apache.
My network setup is like this,
Node1 is connected to switch
Note2 is connected to switch.
My cluster.conf file is as follows,
[root@test01 ~]# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="1" name="mycluster1">
<logging debug="off"/>
<clusternodes>
<clusternode name="test01" nodeid="1">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="test01"/>
</method>
</fence>
</clusternode>
<clusternode name="test02" nodeid="2">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="test02"/>
</method>
</fence>
</clusternode>
</clusternodes>
<fencedevices>
<fencedevice name="pcmk" agent="fence_pcmk"/>
</fencedevices>
</cluster>
And @some point of time am able to see both nodes are registered,
[root@test01 ~]# cman_tool nodes
Node Sts Inc Joined Name
1 M 104 2013-09-17 02:01:11 test01
2 M 108 2013-09-17 02:15:07 test02
And @sometimes with crm_mon -1, I get the following
[root@test01 ~]# crm_mon -1
