Teamcity build agent in disconnected state

Question

I am running teamcity on Linux server, and it was working completely fine. Once I reboot the server machine and it stopped working. I managed to start the teamcity server using runAll.sh command, but the build agent stays in "disconnected" state. The inactivity reason is being shown as 'server shutdown'. I tried to start the agent using 'agent.sh stop' and 'agent.sh start' but it does not seem to work. Could not get anything meaningful from the logs.

Kindly help.

Thanks

Answer 1

Just found this while looking thru my unanswered questions, It was actually a permission issue. I wasn't running the commands as root user. Once I ran 'agent.sh stop' and 'agent.sh start' as a root user, it worked okay.

On the machine that restarted, make sure the firewall didn't come back up in a state that blocks access to/from the agent. When you restart the agent, the teamcity-agent.log file should have a line saying something like, "buildServer.AGENT.registration - Registering on server". If it succeeds, it should say something like "buildServer.AGENT.registration - Registered: id:.., authorizationToken:..".

Incase, if you modified the teamcity port then you'll need to change the build agent configuration files to reflect the new serverUrl value. You can find this setting in the C:\TeamCity\buildAgent\conf\buildAgent.properties file.
