Step-by-Step Guide to Install and Configure Jenkins with Supervisord on Linux

Jenkins Installation and Configuration Guide

Today we share a free open‑source CI/CD tool, Jenkins, written in Java, and show how to install and deploy it.

1. Download Jenkins

Official download page: https://www.jenkins.io/download/

2. Install JDK 1.8

Install JDK 1.8 first (the detailed one‑click method is omitted here). The result is shown in the following screenshot:

3. Install and Configure Supervisord

We recommend using Supervisord to manage the Jenkins process.

Install Supervisord (first enable the EPEL repository):

yum install epel-release
yum -y install supervisor

Start and check Supervisord:

systemctl start supervisord
supervisorctl status
supervisorctl update

If no errors appear, Supervisord is installed successfully.

4. Create Jenkins Directory

mkdir -p /root/Jenkins
mv /root/jenkins.war /root/Jenkins/

5. Configure supervisord for Jenkins

Edit /etc/supervisord.d/jenkins.ini (example content omitted).

supervisorctl update
supervisorctl status

6. Retrieve Initial Admin Password

Check the Jenkins log to find the generated password:

less /root/jenkins/logs/Jenkins.log

7. Complete Web UI Setup

Open the Jenkins web interface, enter the retrieved password, and click the default "Next" button to finish the setup. Screenshots of the process are shown below:

8. Install SSH Publish Plugin

Download and install the SSH plugin "Publish over SSH" from the Jenkins plugin manager (screenshot omitted).

Jenkins is now ready and connected successfully. Good luck!
