Red Hat / CentOS
You can install Jenkins through yum on Red Hat Enterprise Linux, CentOS, and other Red Hat based distributions. You need to choose either the Jenkins Long Term Support release or the Jenkins weekly release.
Long Term Support release
A LTS (Long-Term Support) release is chosen every 12 weeks from the stream of regular releases as the stable release for that time period. It can be installed from the redhat-stable yum repository.
sudo sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key yum install epel-release # repository that provides 'daemonize' yum install java-11-openjdk-devel yum install jenkins
Start Jenkins
You can start the Jenkins service with the command:
sudo systemctl start jenkins
You can check the status of the Jenkins service using the command:
sudo systemctl status jenkins
If everything has been set up correctly, you should see an output like this:
Loaded: loaded (/etc/rc.d/init.d/jenkins; generated) Active: active (running) since Tue 2018-11-13 16:19:01 +03; 4min 57s ago ...
Post-installation setup wizard
After downloading, installing and running Jenkins using one of the procedures above, the post-installation setup wizard begins.
This setup wizard takes you through a few quick "one-off" steps to unlock Jenkins, customize it with plugins and create the first administrator user through which you can continue accessing Jenkins.
Unlocking Jenkins
When you first access a new Jenkins instance, you are asked to unlock it using an automatically-generated password.
Browse to
http://localhost:8080(or whichever port you configured for Jenkins when installing it) and wait until the Unlock Jenkins page appears.
From the Jenkins console log output, copy the automatically-generated alphanumeric password (between the 2 sets of asterisks).
Note:The command:
sudo cat /var/lib/jenkins/secrets/initialAdminPasswordwill print the password at console.If you are running Jenkins in Docker using the official
jenkins/jenkinsimage you can usesudo docker exec ${CONTAINER_ID or CONTAINER_NAME} cat /var/jenkins_home/secrets/initialAdminPasswordto print the password in the console without having to exec into the container.On the Unlock Jenkins page, paste this password into the Administrator password field and click Continue.
Notes:You can always access the Jenkins console log from the Docker logs (above).
The Jenkins console log indicates the location (in the Jenkins home directory) where this password can also be obtained. This password must be entered in the setup wizard on new Jenkins installations before you can access Jenkins’s main UI. This password also serves as the default admininstrator account’s password (with username "admin") if you happen to skip the subsequent user-creation step in the setup wizard.
Customizing Jenkins with plugins
After unlocking Jenkins, the Customize Jenkins page appears. Here you can install any number of useful plugins as part of your initial setup.
Click one of the two options shown:
Install suggested plugins - to install the recommended set of plugins, which are based on most common use cases.
Select plugins to install - to choose which set of plugins to initially install. When you first access the plugin selection page, the suggested plugins are selected by default.
