How to Install Jenkins on OpenBSD

Jenkins is an open-source, Java-based automation tool that enables the continuous build, test, and deployment of software. This tutorial will take you through the steps for installing Jenkins on OpenBSD.

Prerequisites

Before getting started, ensure that you have the following:

• OpenBSD installed on your machine
• A user account with sudo privileges
• Java Virtual Machine (JVM) installed

Steps

1. First, update the package repository and install the wget package:

$ sudo pkg_add wget

2. Next, download the latest version of Jenkins by visiting their official website at https://jenkins-ci.org/. Copy the URL of the latest stable release.

3. Use wget to download the Jenkins installation file:

$ wget <Jenkins_URL>

4. Extract the downloaded file:

$ tar xzf jenkins-*.war

5. Move the jenkins.war file to the /usr/local/share/jenkins/ directory:

$ sudo mkdir /usr/local/share/jenkins/
$ sudo mv jenkins.war /usr/local/share/jenkins/

6. Create a new user account for Jenkins and grant it permission to access the Jenkins directory:

$ sudo useradd -d /var/jenkins -m -s /bin/sh jenkins
$ sudo chown -R jenkins /usr/local/share/jenkins/

7. Create a new file /etc/rc.d/jenkins with the following content:

#!/bin/sh
#
# start and stop the Jenkins server
#

daemon="/usr/bin/daemon"
daemon_flags="-r -P /var/run/jenkins.pid -f /usr/local/bin/java -- -jar /usr/local/share/jenkins/jenkins.war"
name="jenkins"

rcvar=${name}_enable
start_cmd="${daemon} ${daemon_flags}"
stop_cmd="pkill -15 -f ${daemon_flags}"

. /etc/rc.d/rc.subr

8. Make the script executable:

$ sudo chmod 755 /etc/rc.d/jenkins

9. Enable the Jenkins service at system boot and start it:

$ sudo rcctl enable jenkins
$ sudo rcctl start jenkins

10. Verify that Jenkins is running:

$ sudo rcctl check jenkins

If Jenkins is running, you should receive the following output:

jk_status: jenkins(ok)

11. Access the Jenkins web interface by opening a web browser and navigating to http://localhost:8080.

12. Complete the setup wizard by following the prompts.

Congratulations! You have successfully installed Jenkins on OpenBSD.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
