hanging the port of Jenkins a little bit tricky and sometimes it becomes a bottleneck of the using Jenkins. Some we installed Jenkins on its default port 8080. But after that, we realized that some of the other processes are being used on port 8080 ( currently that process was stopped and 8080 is free). So we need to change the port of Jenkins. So in this tutorial, we'll see how we can change the port of Jenkins. We'll change the port 8080 to 7070.
So let's get started.

Change the port of Jenkins:

Change the port of Jenkins from 8080 to 7070. To change the port, follow the instruction below:
In your machine, Goto the location:

                                cd /
                                cd usr/local/Cellar/jenkins/2.x.x

Now run command ls and see the below file (it should be there):

homebrew.mxcl.jenkins.plist

Now open the file homebrew.mxcl.jenkins.plist using open command as:

open homebrew.mxcl.jenkins-lts.plist

The above command will open this file in your default editor:

Now you need to change the port in string --httpPort=7070.
Now restart the Jenkins using below command:

brew services restart jenkins-lts

Note: if you have Jenkins.war file then run the command java -jar Jenkins.war –httpPort=7070. You need not do anything to change the port. You can just give the port using command line.
Now open you Jenkins on port 7070 ( I'll use port 7070 in a further post):
Now, you've successfully changed your Jenkins port. Now open URL "localhost:7070" and you can see the Jenkins is running on port 7070.
