Proper way to install jenkins in macOS

In this post, we will see how we can effectively install and setup jenkins on MacOS, we will use brew command to perform the jenkins installation which reduces the installation time and also avoids permission issues in Mac.

so let’s get started

Note – make sure you have Homebrew installed.

If brew not installed, then open terminal and type [follow the steps]

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Install jenkins

brew install jenkins-lts

Note – lts – long term support version

Homebrew may updated automatically and then you will get the output as

==> Downloading http://mirrors.jenkins.io/war-stable/2.164.3/jenkins.war
==> Downloading from http://ftp-nyc.osuosl.org/pub/jenkins/war-stable/2.164.3/je
######################################################################## 100.0%
==> jar xvf jenkins.war
==> Caveats
Note: When using launchctl the port will be 8080.
To have launchd start jenkins-lts now and restart at login:
  brew services start jenkins-lts
Or, if you don't want/need a background service you can just run:
  jenkins-lts
==> Summary
  /usr/local/Cellar/jenkins-lts/2.164.3: 7 files, 77.3MB, built in 52 seconds

Install a specific LTS version: brew install jenkins-lts@YOUR_VERSION

Start the Jenkins service: brew services start jenkins-lts

Restart the Jenkins service: brew services restart jenkins-lts

Update the Jenkins version: brew upgrade jenkins-lts

Update the jenkins-lts.plist file

Now navigate to this path and open /usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist file

find below line

<string>--httpListenAddress=127.0.0.1</string>

and change to

<string>--httpListenAddress=0.0.0.0</string>

Start the jenkins server

If you want to keep the jenkins running all the time [jenkins will start automatically if you turn on your system], then run command

brew services start jenkins-lts

else, just run command

jenkins-lts

You will get below result

==> Successfully started `jenkins-lts` (label: homebrew.mxcl.jenkins-lts)

Open jenkins

Now navigate to the browser and type localhost:8080

Unlock jenkins

Browser will indicate you to navigate to a hidden folder

/Users/MacUser/.jenkins/secrets/initialAdminPassword

To make the hidden folder visible in mac, navigate to your user folder and type key press combination Command + Shift + >

under the .jenkins | secerts folder, open the InitialAdminPassword file and copy the password and paste into browser, click Continue

Install recommended plugins

Create a user

and you are done

Note – To restart the jenkins server

brew services restart jenkins-lts
