OK, I am trying to set up a heartbeat cluster with SUSE Linux here. I have 3 machines:
- heartbeat-1, 192.168.0.21 (virtual)
- heartbeat-2, 192.168.0.22 (virtual)
- tweedleburg, 192.168.0.5 (physical)
On heartbeat-*, I install SLES 10 as per default, but I disable ZMD and the firewall. On tweedleburg, I install an iscsi storage. I want to install a highly available web server to gain some experience with clustering. We use heartbeat as cluster manager.
- establish passwordless login between heartbeat-1 and -2.
- adapt /etc/hosts on both nodes so that it contains
192.168.0.21 heartbeat-1.site heartbeat-1 192.168.0.22 heartbeat-2.site heartbeat-2
- configure the cluster on node 1
heartbeat-1:~ # yast2 heartbeat
Choose MD5 as auth method and myauth as password.
- install heartbeat on node 2
heartbeat-1:~ # yast -i heartbeat
- propagate the heartbeat configuration
heartbeat-1:~ # scp /etc/ha.d/ha.cf root@heartbeat-2:/etc/ha.d heartbeat-1:~ # scp /etc/ha.d/authkeys root@heartbeat-2:/etc/ha.d
- start the cluster
heartbeat-1:~ # /etc/init.d/heartbeat start heartbeat-2:~ # /etc/init.d/heartbeat start
- set a password for the hacluster admin
heartbeat-1:~ # passwd hacluster
- configure the cluster
heartbeat-1:~ # hb_gui
Log in as hacluster user to heartbeat-1
- build sfex from http://www.linux-ha.org/sfex on both nodes
- set up an iscsi initiator on both nodes, we assume it makes the device /dev/sdb.
