Change Jenkins port on macOS

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!

it looks like the default way is:

#add the default parameters - this will edit /Library/Preferences/org.jenkins-ci.plist

> sudo defaults write /Library/Preferences/org.jenkins-ci httpPort 7070

#stop

> sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist

#start

> sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist

Before modify the Jenkins port on macOS,you must pay attention to the way of installation of Jenkins.

Here I recommend you install Jenkins by 'Homebrew' if you want to deal with iOS project building,because you may meet some errors that the way of using .pkg to install,it's really hard to solve the problems.

I have installed Jenkins LTS by brew command:

brew install jenkins-lts

So my Jenkins plist file is here:

/usr/local/Cellar/jenkins-lts/2.121.2/homebrew.mxcl.jenkins-lts.plist

You can modify the httpPort value from default 8080 to the other value,and then save the file.

sudo launchctl unload command will not work for you.You must try these commands to restart your Jenkins and make the port modification works.

brew services stop jenkins-lts
brew services start jenkins-lts

ifeegoo:~ ifeegoo$ brew services stop jenkins-lts
Stopping `jenkins-lts`... (might take a while)
==> Successfully stopped `jenkins-lts` (label: homebrew.mxcl.jenkins-lts)
ifeegoo:~ ifeegoo$ brew services start jenkins-lts
==> Successfully started `jenkins-lts` (label: homebrew.mxcl.jenkins-lts)

Note:If you installed Jenkins LTS,you must pay attention that your command must be jenkins-lts,not jenkins.

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.

This worked for me for changing port to 7070 or other.

sudo defaults write /Library/Preferences/org.jenkins-ci httpPort 7070

sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist

sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist

More info about this

I have installed Jenkins on my Mac OS High Sierra using Brew.

Please follow below steps:

1. You have to change the port to below file: > /usr/local/Cellar/jenkins/2.x.x/homebrew.mxcl.jenkins.plist

2. Assign any free port like 7070 or any number you want.[If you have static IP then you can give port 80(HTTP)]

   --httpPort=7070

3. You also need to restart the Jenkins Server. using below brew service commands:

$ brew services stop jenkins

$ brew services start jenkins

That's all.!

Just write the following command in the terminal:

sudo defaults write /Library/Preferences/org.jenkins-ci.plist httpPort 9999

sudo launchctl unload /Library/LaunchDaemons/org.jenkins-ci.plist

sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist

That should resolve it.
