Hello, I reinstalled a new VM, with CentOS this time. Made sure the firewall is off, and selinux is disabled. Checked the requirements and made sure they where met. Got up to the point of the installation failing to receive a heartbeat. Error found in the logs: ERROR Heartbeating to 127.0.0.1:7182 failed. Traceback (most recent call last): File "/usr/lib64/cmf/agent/src/cmf/agent.py", line 815, in send_heartbeat self.master_port) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/avro-1.6.3-py2.6.egg/avro/ipc.py", line 464, in __init__ self.conn.connect() File "/usr/lib64/python2.6/httplib.py", line 720, in connect self.timeout) File "/usr/lib64/python2.6/socket.py", line 567, in create_connection raise error, msg error: [Errno 111] Connection refused Apparently the hostname and hostname -f returned a diferent name. So I had to align them. Updated both /etc/hosts and /etc/sysconfig/network files to have the same hostname (without capitals.) Restart network, and reboot the VM Retried the adding of the host, this time with success. Hope this helps some other troubled users installing ! Regards, Ken.
