How to start Jenkins on a different port rather than 8080

Question

I am facing an error every time I start Jenkins on the 8080 port. Is there a way to run the same Jenkins instance on another port?

Answer 1

This is simple, use the following command:

java -jar jenkins.war --httpPort='xyz'

For https,

java -jar jenkins.war --httpsPort='xyz'

Finally, restart the service, this should change the port permanently.

Answer 2

In case you want to change the default jenkins port on Linux,

• You can go to /etc/default/jenkins  

• add --httpPort=9999 or whatever port to JENKINS_ARGS.

• Then you should restart Jenkins with sudo service jenkins restart.

Jenkins is installed on Linux server still it is not showing the path ..... like /etc/default/????

Hi@Nishant,

It depends on the version to version. In the newer version of Jenkins, you can find the configuration file in the /etc/sysconfig/jenkins file.
