Re: [Linux-cluster] Need simple RHEL4.0 clarification



Hello

1 - ccs_tool lsnode gives you the Cluster name and node names

2 - this as already been posted here a few weeks ago (title: ccs_test tool on 2006-11-15) Basically you need to create a script to parse the contents of the cluster.conf file.

Anyway here a simple script we came up with to do this:


filename:get_service_ip.py
--- CUT HERE ---

#!/usr/bin/python

# GET IP FROM SERVICE CONFIG
import xml.dom.minidom, sys
doc = xml.dom.minidom.parse('/etc/cluster/cluster.conf')
services=doc.getElementsByTagName('service')
for service in services:
       name=service.getAttribute('name')
       try:
               if (name==sys.argv[1]):
                       ips=service.getElementsByTagName('ip')
                       for ip in ips:
                               ref=ip.getAttribute('ref')
                               print ref
       except:
               pass

-- CUT HERE ---

You can get the ip like this:

get_service_ip.py <service name>

Example:
#  get_service_ip.py mysql
192.168.0.2

Hope this helps

Marcos David

Dear friends,

I am working on a project on RHEL 4.0 cluster platform.
I appreciate if you could help/give me pointer me for below queries as I couldn't find it.

1. What is the command to find cluster name/how to extract cluser name?
( RHEL 3.0 we can extrsact cluster name either by clustat or redhat-config-cluster-cmd --cluster)

2. What is the command to see service(virtual) IP address for given service/group. ( RHEL 3.0 redhat-config-cluster-cmd --service=<service name> --service_ipaddresses would work )

Thanks in advance
- Krishna
