down掉node1伺服器的apache服務，node1首先會自動重啟apache服務，
但如何才能VIP和apache服務會自動轉換到node2伺服器上？

read documents:
if you are using redhat cluster suite, you will need
a) power fencing device (must have)
b) chkconfig --leve 35 cman on
service cman start
c) chkconfig --level 35 rgmanager on
service rgmanager on
d) chkconfig --del httpd on node1 and node2
add httpd to the resource and service using conga
