Installation
[ALL] installation pacemaker
sudo apt-get install pacemaker
edit /etc/default/corosync and enable corosync (START=yes)
[ONE] generate corosync authkey
sudo corosync-keygen
(this can take a while if there's no enough entropy; download ubuntu iso image on the same machine while generating to speed it up or use keyboard to generate entropy)
copy /etc/corosync/authkey to all servers that will form this cluster (make sure it is owned by root:root and has 400 permissions).
[ALL] configure corosync
In /etc/corosync/corosync.conf, replace bindnetaddr (by default it is 127.0.0.1), with the network address
of your server, replacing the last number by 0 to get the network address. For example, if your IP is
192.168.1.101, then you would put 192.168.1.0.
