After run agent, waiting for download
Hi
after run agent on slave machine freeze in this step:
[machine@slave ~]$ /opt/rhq-agent/bin/rhq-agent.sh start
Unused option: start
RHQ 4.12.0.JON330GA Update 12 [e80b551] (Sat Jun 22 07:06:55 IRDT 2019)
The agent is waiting for plugins to be downloaded...
>
Workaround:
- ping master and slave with ip and name successful
- add ip and name in hosts file
- no proxy
- no firewall! No iptable on slave and master
- Permission of /opt = 777
- Jboss ON version 3.3 update 12
