Change Jenkins port on macOS

Question

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

Answer 1

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.
