Jenkins Installation and Setup


With the release of 2.0, the installation of Jenkins remains largely the same but the initial setup is different. After you have chosen your preferred OS or container for installation the first time you run Jenkins you will be presented with a setup wizard to properly configure Jenkins. Jenkins will not be accessible via the web interface or CLI until the initial setup is complete.

INFO: This is a new Jenkins instance. The Plugin Install Wizard will be launched.

System Requirements

Jenkins requires Java7 or above and Servlet 3.1 to function. Java8 is recommended. Jenkins requires a fair amount of memory to operate well. Smaller installations should start around 256MB-1GB.


Unix/Linux Installation

Jenkins has native integrations with the following OSes. See respective sections for how to make Jenkins run in the background automatically:

Alternatively, if you have a servlet container that supports Servlet 3.1/JSP 2.0, then you can run them as services, and deploy jenkins.war as you would any other war file. Container specific documentation is available if you choose this route.

Windows Installation

If you're running on Windows it is good to run Jenkins as a service so it starts up automatically without requiring a user to log in. The easiest way is to run the Windows installer, linked from Jenkins' homepage. This also has the advantage of being easier to automate.

The manual way is to follow Installing Jenkins as a Windows service. Alternatively, you can install a servlet container like GlassFish and Tomcat, which can run as a service by itself, and then deploy Jenkins to it.

Since Jenkins was written to work on unix-like platforms, some parts assume the presence of unix-utilities. It is advised to install these as well on Windows. Install UnxUtils (this includes a shell that seems to work with forward and backwards slashes and does globbing correctly)(UnxUtils does not download), put it in the Windows PATH , and copy sh.exe to C:\bin\sh.exe (or whichever drive you use) to make shebang lines work. This should get you going. If UnxUtils gives you trouble (Fork Failed Errors), try Win-Bash.

Setup Wizard

Jenkins 2.0 is no longer installed completely open and accessible to the world. Instead Jenkins is initially configured to be more secure. Jenkins can no longer be accessed without a username and password and open ports are limited. During the initial run of Jenkins a security token is generated and printed in the console log:

Jenkins initial setup is required. A security token is required to proceed.
Please use the following security token to proceed to installation:

This token must be input in the Setup Wizard the first time you open the Jenkins UI. This token will also serve as the default password for the user 'admin' if you skip the user-creation step in the Setup Wizard.

In addition to configuring the initial security for Jenkins the Setup Wizard will also install the initial plugins in your installation. Previously,Jenkins included several bundled plugins based on a set of assumed use cases. However, as technology and tools have changed the list of bundled plugins included with Jenkins has not kept up to date. Rather than continuously updating a list of bundled plugins, Jenkins 2.0 begins with a setup wizard asking the user to choose the initial plugins to be installed. The recommended set of plugins available are based on the most common use cases but users are free to customize their own installion.
