Hi , i am new to start use pacemaker , i wanna make a simple demo to start a
apache in a node
follow the doc i succeed to setup a pacemaker-openais env.
there are four nodes . test1 ,test2 ,ubuntu ,bak1
ubuntu is the one i wanna to start a apache app, and if it shutdown ,bak1
gets its work.
so i setup apache both on ubuntu and bak1 ,path localed at
/usr/local/apache.
and i dont know LSB and OCF script at all. so i found apache script at
ha.f/resource.d/ and use it
and finally found IPaddr start no problem and apache is not installed.
is there any example for me to follow to writer a LSB script to start my
apache at /usr/local/apache
or something LVS demo concluded ,thanks.
here is my configure
node bak1
node test1 \
attributes standby="off"
node test2 \
attributes standby="on"
node ubuntu \
attributes standby="off"
primitive failover-apache ocf:heartbeat:apache \
op monitor interval="15" \
params configfile="/usr/local/apache/
conf/httpd.conf"
primitive failover-ip ocf:heartbeat:IPaddr \
params ip="192.168.1.200" \
op monitor interval="10s"
