Jenkins may be installed on either Windows or Unix platforms, but we will focus on Windows installation only. Prerequisites: Before you proceed to install Jenkins in your windows system, there are some prerequisites for Jenkins to install Jenkins in your computer. In this lesson, take a look at installing Jenkins as a service on the Mac operating system. And the latest version of Java installed, open a browser to jenkins.io/download. Scroll down the. Download the jx binary. On a Mac you can use brew: brew install jenkins-x/jx/jx Alternatively. To install Jenkins X on Linux, download the.tar file. Generally it should suffice to install Java 8 and download the jenkins.war and run it as a standalone process or under an application server such as Apache Tomcat. Download hasn't started?

I wanted to blog about how to get Jenkins running on a Mac using its installer.
Jenkins is a great product, but its frenetic and crazed (but cheerful and enthusiastic) development process often shows through.
Case in point: the default Mac installer, which you can download from the jenkins-ci.org website, sets up Jenkins to run as a Mac LaunchDaemon running as user daemon.
Now, there's nothing inherently wrong with this–indeed, it can be quite nice.?? You'll only have one instance of Jenkins running, and no user needs to be logged on for it to do its thing, and if Jenkins ever got hacked you're running as a low-privilege user rather than as some kind of full-fledged user with the ability to ruin your day.
However, this caused some weird problems, nullifying the entire intent of a one-click installer.?? These problems manifest themselves the moment you try to run a Maven build, which suggests to me that this (simple) smoke test is simply not run before new versions of the installer are released.?? Oh well, time to roll up our sleeves and turn the one-click installation process into an exercise in Mac system administration.?? ?
What's wrong with daemon?
The first thing to know about user daemon is that his home directory is /var/root.?? That should start to give you a funny feeling.
The reason that should give you a funny feeling is that Maven looks for its settings.xml file in $HOME/.m2.?? Which of course does not exist in /var/root.
So when Jenkins launches, it appears to come up fine.?? But if you try to run a Maven build, you'll get a lovely stack trace about how the file /var/root/.m2 couldn't be created.
When I first encountered this error, I just wanted to get the stupid thing working, so I did:
sudo chmod a+rwx /var/root/.m2
So this gets Jenkins-running-as-daemon past this problem, but now it wants to create temporary files in /Users/Shared/Jenkins/Home, which it doesn't own, and can't write to.
At any rate, I now realized that I didn't want this thing running as user daemon anyway, because I didn't want him doing anything to /var/root.?? And even if I could somehow tell him to use a different user directory so that $HOME/.m2/settings.xml would be resolved somewhere else, it was clear that I was going to have to edit .plist files.?? So, so much for the installer.?? And as long as the installer wasn't going to work, I decided that I wanted to make Jenkins run as a different kind of daemon user anyway.
This turned out (for this rookie Mac system administrator) to be quite difficult.
The steps involved are: Download quickbooks plus edition 2016 mac.
- Create a daemon user (I called mine _jenkins)
- Create a daemon group (I called mine???surprise!???_jenkins)
- Put the daemon user in the newly-created daemon group
- Create the home directory for the new daemon user (/Users/_jenkins in my case)
- chown the /Users/Shared/Jenkins directory so that its hierarchy is owned by your new user.
- edit /Library/LaunchDaemons/org.jenkins-ci.plist so that it reflects all this information.
Creating the user is a task that should not be accomplished through the usual Mac GUI methods.?? You need to use dscl instead.?? This is because you want to create a daemon user.?? I snooped around for a bit and came up with this lovely tutorial: http://www.minecraftwiki.net/wiki/Tutorials/Create_a_Mac_OS_X_startup_daemon#The_hard_.28and_correct.29_way.?? It walked me through steps 1-4 above.
Then I did:
sudo chown -R _jenkins:_jenkins /Users/Shared/Jenkins
Finally, my /Library/LaunchDaemons/org.jenkins-ci.plist looks like this:
<?xml version='1.0' encoding='UTF-8'?>

I added the _JAVA_OPTIONS environment variable to force UTF-8 encoding.?? This is because no matter what kind of encoding you might specify in your Java code, Java-on-the-Mac's character encoding for what gets put out to the terminal is MacRoman by default (?!).?? You have to get the file.encoding property passed into the JVM early enough so that it is picked up by the rest of the JVM internals, and the only way to do that is to use the special _JAVA_OPTIONS environment variable picked up by all the Java tools in $JAVA_HOME/bin.?? The only unfortunate side effect of all this is that you get a warning printed to the screen on every JVM startup that says, effectively and incomprehensibly, I am using the environment variable you told me to.
Once you've done all this, you can simply stop the launch daemon and it will automatically restart with the new values:
I hope that helps other Jenkins Mac users out.
Jenkins is Continuous Integration automation control software that allows developers to automate repetitive parts of the software development process. While Jenkins can be installed on many operating systems, this guide will focus on the macOS install process.
This guide assumes you have a fresh install of the latest macOS along with Xcode, and that you don’t already have a Jenkins master server. In a future guide, we will add Jenkins slave servers to the setup.
There are a few ways to install Jenkins on macOS – we’re going to install it using a package manager for macOS called Homebrew. If Homebrew is already installed then skip the next step (check by running “brew -v” in Terminal).
Let’s install Homebrew by opening Terminal and entering the following command (this command is all one line): https://sixname.weebly.com/free-download-football-manager-2018-mac.html.
The installer will give you a list of things it’s going to do, just press enter and Homebrew will be installed.
Now that you have Homebrew installed, you can type check to see if there are any recommendations for your setup:
For example, you may have an outdated version of Xcode, in which case you may want to upgrade that:
Before installing Jenkins, we need to install a specific version of Java required by Jenkins – it may ask you for your password to set permissions properly:
Now we can install Jenkins – we’re going to install the LTS (long-term support version, which is typically more stable):
We want the Jenkins web interface to be accessible from anywhere (not just on the local machine), so we’re going to open up the config file:
Find this line:
And change it to:
(to exit out of nano after making the change, hit Ctrl+X, hit Y to save the changes, and hit Enter)
How To Download Jenkins On Mac Os
Let’s start Jenkins and set it to run automatically when the system is rebooted:
The rest of the configuration will mostly be done in a browser on the local machine. https://sixname.weebly.com/can-you-download-java-for-mac.html. Open up Safari and visit http://localhost:8080 , where we will see a screen like this:
Grab the red highlighted text and in Terminal use the ‘cat’ command to display the initial password:
Copy that password and paste it into the Unlock Jenkins page. We’re done with Terminal, feel free to close it.
We can now Customize Jenkins and install some plugins. For now we’re going to choose Install suggested plugins.
The installer now downloads and installs the plugins:
Create an admin user and Save and Continue:
Set the URL that users will be using to log in to Jenkins. If users will be connecting to the server remotely, it’s best to set up an A record (like jenkins.yourdomain.com) and set the Jenkins URL to http://jenkins.yourdomain.com:8080. Click Save and Finish:
Setup is complete – click Start using Jenkins.
The rest of the configuration will be done within the Jenkins web interface. You can now create jobs, manage Jenkins and install new plugins, and add new users.
How to Start / Restart Jenkins on macOS

To restart the Jenkins service and make sure it runs after a reboot:
Note: If you didn’t install the LTS version of Jenkins, don’t include the “-lts” portion of the above commands.
