Dear all,
i have read the clusterbook, but i have not understand how can i
configure example three services so that if one service failed, all
three services switch to another node.
Example:
primitive ServiceAmavis lsb:amavis op monitor interval="10" timeout="20s"
primitive ServiceApache lsb:apache2 op monitor interval="10"
primitive ServiceCyrus lsb:cyrus2.2 op monitor interval="10" timeout="20s"
what must i configure if i kill example apache process, that switch all
three to another node?
You need to configure groups so that all resources run together or not
at all
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/ch-advanced-resources.html#group-resources
But also take a look at ordering
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-resource-ordering.html#id2003768
and colocation
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Explained/s-resource-colocation.html#id1993383
And also check whether the init scripts are LSB compliant
http://refspecs.linux-foundation.org/LSB_3.2.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html
And for apache please use the ocf:heartbeat:apache resource agent

HTH,

Thanks
Thomas
