A node agent is created using the create-node-agent command. The following example creates node agent named mynodeagent. The administration server host is myhost, the administration server port is 1234, and the administrative username is admin. The command normally prompts for the administrative passwords; however, if the --savemasterpassword option is not specified or false, the command does not prompt for the administrative passwords.
$ asadmin create-node-agent --host myhost --port 1234 --user admin mynodeagent
For the full syntax, type asadmin help create-node-agent.
