Hi,

When registering host go with Manual Installation.

and edit /etc/ambari-agent/conf/ambari-agent.ini

change hostname=ambari server name

Then Retry Failed.

@Aymen Rahal

if you are doing manual installation, you need to install ambari-agent first on each of your servers. use repos to install and edit the /etc/ambari-agent/conf/ambari-agent.ini to use the ambari server hostname and start ambari-agent.

when you are adding your hosts, use manual installation .. you dont need ssh key in this case.

@Aymen Rahal

The issue is due to 'Connection refused on the default ssh port'. Verify the following:

1. Check the ssh port under file /etc/ssh/sshd_config, if not set try setting to 22.

2. Try running ssh to the host from terminal.
