[OSR-users] Relocate a service
|
From: Stefano E. <ste...@so...> - 2009-06-03 12:49:06

Hi Mark,
I changed two lines of the script /usr/share/cluster/ip.sh,
I have attached the script and the lines that I have changed are
immediately below the written CHANGED.
Now the service httpd start on the new ip address (10.43.100.204), and
if the nodo_1 goes down,
the service is relocated on nodo_2.
when I start the service, in the log messages I have:
Jun 3 13:56:58 clu01 clurgmgrd[14899]: <notice> Starting disabled
service service:RHTTPD
Jun 3 13:56:59 clu01 in.rdiscd[15391]: setsockopt
(IP_ADD_MEMBERSHIP): Address already in use
Jun 3 13:56:59 clu01 in.rdiscd[15391]: Failed joining addresses
Jun 3 13:57:00 clu01 clurgmgrd[14899]: <notice> Service
service:RHTTPD started
but despite this, the service httpd works.
I hope that the information that I am writing you, you are useful.
Bye.
