When I list the LibPython module under /usr/lib64/libpython* , It only has the 2.4 modue. So we need to install the 2.6 Module required by the opscenter.

1, first, Check my OS, it ‘s Centos 5

go to http://download.fedora.redhat.com/pub/epel/5/x86_64/, download the epel-release-5-4.noarch.rpm 

2. Update the rpm, “rpm -Uvh epel-release*rpm”

3. yum install python26-libs

Once done, you can see the 2.6 modules under the lib folder,

Now we can run the opscenter now.
