RHEL  6: Configuring a cman-based cluster to use a specific network interface
1)Define all nodes in /etc/hosts.
If these nodes do not have any pre-existing hostname on that network, then names can be assigned to them in this file,
 as long as those names don't conflict with others hosts on the network.

192.168.143.61 node1.google.com node1
192.168.143.62 node2.google.com node2
Note: configure above ip's manullay on both nodes for private communication.
2)RPM need to install on both nodes.
Note: - Configure YUM on web

3)Starting Cluster Software
type the following commands in this order:
1)service cman start
2)service clvmd start -----> if CLVM has been used to create clustered volumes
3)service gfs2 start---------> if you are using Red Hat GFS2
4)service rgmanager start--------> if you using high-availability (HA) services (rgmanager).
--------
To stop the cluster software on a node,
type the following commands in this order:
1)service rgmanager stop
2)service gfs2 stop
3)umount -at gfs2
4)service clvmd stop
5)service cman stop
4) Staring Cluster GUI .
# yum install luci
# service luci start
Starting luci: generating https SSL certificates...  done
                                                           [  OK  ]
/etc/sysconfig/luci is configuration file.
https://10.25.12.20:8084/

By using gui we need to configure
1) Clster name
2) cluster members
3) fencing
4) quorum devices
5)resources,& service groups.

5) then it generates cluster.conf file
6. After completing configuration of the rest of the necessary components and starting the cman service, check cman_tool status to see what addresses the nodes are communicating over:
Raw
[root@node1 ~]# cman_tool status | grep "Node addresses"
Node addresses: 192.168.143.61
Raw
[root@node2 ~]# cman_tool status | grep "Node addresses"
Node addresses: 192.168.143.62

after install cluster tools then only configure pvs,vgs,lvs other wise it does not recognize.

===================
RHEL 7: Configuring a corosync-based cluster to use a specific network interface.
1. Define all nodes in /etc/hosts.
 If these nodes do not have any pre-existing hostname on that network, then names can be assigned to them in this file,
 as long as those names don't conflict with others hosts on the network.

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.143.61 node1.example.com node1
192.168.143.62 node2.example.com node2
2. Set up the cluster with pcs,
the pcsd web interface, or directly in /etc/corosync/corosync.conf, specifying names matching those that were added in /etc/hosts. For example:

# pcs cluster setup --name myCluster node1.example.com node2.example.com
Which would produce a nodelist definition in /etc/corosync/corosync.conf with those names as the "ring0_addr" for each node:
Raw
nodelist {
  node {
        ring0_addr: node1.example.com
        nodeid: 1
       }
  node {
        ring0_addr: node2.example.com
        nodeid: 2
       }
}














NOTE: RHEL 7 corosync supports the usage of Redundant Ring Protocol in which multiple redundant interfaces can be used to communicate in the cluster.
In such configurations, the "ring1_addr" should be defined in /etc/hosts the same way the primary name was.
3. Upon starting the cluster with pcs cluster start [--all], check the output of corosync-cfgtool on each node to see what addresses are being used for node communication:
[root@node1 ~]# corosync-cfgtool -s
Printing ring status.
Local node ID 1
RING ID 0
    id  = 192.168.143.61
    status  = ring 0 active with no faults
[root@node1 ~]# corosync-cfgtool -s
Printing ring status.
Local node ID 1
RING ID 0
    id  = 192.168.143.62
    status  = ring 0 active with no faults

Kernel upgradation in RHEL

Kernal Software :-
kernel debuginfo is required for vmcore analysis
debug kernel is compiled to troubleshoot issue
kernel - devel and headers is for compiling new kernel
kerne - doc is documentation
For kernel upgradation below two RPM's are mandatory.
kernel-2.6.32-431.el6.x86_64
kernel-firmware-2.6.32-431.el6.noarch
#rpm -ivh kernel-2.6.32-431.el6.x86_64
#rpm -ivh kernel-firmware-2.6.32-431.el6.noarch
#reboot
