I was wondering how one could change Jenkins’ default port 8080. Using linux or windows, this is simply done with the configuration file. But the Mac config file of Jenkins looks completely different from the other ones.

Of course one could pass the –httpPort parameter when starting the server, but I want to do this within a config file.

Is there an option for that?

PS: Passing the Jenkins instance through apache would kinda solve the problem, but I want to change the Jenkins port.

Thanks!

    I’ll walk you through it:

    cd /Applications/Jenkins
    sudo vi winstone.properties
    Add httpPort=9999 to the file. To see all the options you can put in there type java -jar jenkins.war --help

    run java -jar jenkins.war from /Applications/Jenkins. Your port will be changed. jenkins.war picks up config options from ./winstone.properties by default.
