Python – Ambari 2.0 installation in centOS 5

I plan to set up Ambari 2.0 with a node in CentOS 5. I successfully set up an Ambari server in one box and tried to automatically install the Ambari agent in another box via the Ambari Management Server UI. I have a passwordless SSH with my other server and it works fine, but I get the following error when trying to register with another node. Can anyone help with this?

IOError: [Errno 2] No such file or directory: '/var/lib/ambari-agent/data/version'

It looks like the ambari-agent

you installed on that host doesn’t work because of the error: No such file or directory: '/var/lib/ambari-agent/data/version' I'll uninstall and reinstall it:

sudo yum erase ambari-agent
sudo yum install ambari-agent

Then try the installation again.
