I installed Jenkins yesterday (together with apache2). Jenkins started fine and everything was ok. Then I decided to stop jenkins and apache because I planned to configure them today. Now when I start Jenkins i get this error:
Jenkins startup error
I have tried some other Ports like 8081 or 4xxxx, nothing helped.
How can i fix this? Please help.
System:
- Debian 6.0
- Installation of Jenkins through the offical repo.
- Apache has no vhosts except the 000-default
- netstat shows nothing on 8080 or the 4xxxx Port
The problem is quite easy to pin:
This means that for the given address:port there is already a process which is binding to it. Please, use the operating system tools to find this process and, eventually, kill it. Then start Jenkins again.
Additionally, I can add, that it almost certainly Jenkins, which was not stopped correctly or, due to some error, did not stopped entirely.
