Check out our guide to learn how to install Java on Ubuntu<\/a>.<\/p>\n <\/div>\n \n\n\n\n<\/p>2. Install Jenkins<\/h3> Now, we will install Jenkins itself. Issue the following four commands in sequence to initiate the installation from the Jenkins repository:<\/p>
curl -fsSL https:\/\/pkg.jenkins.io\/debian-stable\/jenkins.io.key | sudo tee \\\n \/usr\/share\/keyrings\/jenkins-keyring.asc > \/dev\/null\n\necho deb [signed-by=\/usr\/share\/keyrings\/jenkins-keyring.asc] \\\n https:\/\/pkg.jenkins.io\/debian-stable binary\/ | sudo tee \\\n \/etc\/apt\/sources.list.d\/jenkins.list > \/dev\/null\n\nsudo apt-get update\n\nsudo apt-get install jenkins<\/pre>Once that’s done, start the Jenkins service with the following command:<\/p>
sudo systemctl start jenkins.service<\/pre>To confirm its status, use:<\/p>
sudo systemctl status jenkins<\/pre>If it’s working correctly, the terminal window will look like this:<\/p>
\n
3. Adjust Firewall and Configuring Jenkins<\/h3> With Jenkins installed, we can proceed with adjusting the firewall settings. By default, Jenkins will run on port 8080<\/strong>.<\/p>In order to ensure that this port is accessible, we will need to configure the built-in Ubuntu firewall<\/a> (ufw). To open the 8080 port and enable the firewall, use the following commands:<\/p>sudo ufw allow 8080<\/pre>sudo ufw enable<\/pre>Once done, test whether the firewall is active using this command:<\/p>
sudo ufw status<\/pre>\n
\n\n
\n
\n
\n \n <\/svg>\n \n Pro Tip <\/p>\n <\/div>\n
If an error about the ufw command not being available appears, install it using the sudo apt install ufw<\/strong> command and proceed with the steps as shown above.<\/p>\n <\/div>\n \n\n\n\n<\/p>As an alternative, you can also set up a firewall via hPanel. Select your VPS and click on the Firewall<\/strong> button:<\/p>\n
\n\t\t\t\n\t\t\t\t<\/path>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n<\/div>Then, create a new firewall configuration and give it a name. Once done, you will be able to edit the configuration and add any preferred firewall rules:<\/p>
\n
Once finished, remember to click the toggle<\/strong> on your new firewall configuration to activate it. <\/p>With the firewall configured, it’s time to set up Jenkins itself. Type in the IP of your VPS along with the port number. The Jenkins setup wizard will be similar to the example below:<\/p>
\n
Just make sure to replace 185.185.185.185<\/strong> with an actual IP. An administrator password will be needed to proceed with the configuration. It can be easily found inside the \/var\/lib\/jenkins\/secrets\/initialAdminPassword<\/strong> file. To check the initial password, use the cat<\/strong> command<\/a> as indicated below:<\/p>sudo cat \/var\/lib\/jenkins\/secrets\/initialAdminPassword<\/pre>Copy the password, go back to the setup wizard, paste it and click Continue<\/strong>.<\/p>\n
Next, the Customize<\/strong> Jenkins<\/strong> window will appear. We recommend simply selecting the Install suggested plugins <\/strong>option for this step.<\/p>\n
Give it a couple of minutes for the installation process to complete. Once it’s done, specify your username, password, full name, and email address, and click on Save and Continue<\/strong> to create an admin user.<\/p>\n
Then specify the preferred Jenkins<\/strong> URL <\/strong>and finish the configuration process.<\/p>\n
After configuration, the Jenkins dashboard will appear, meaning the Jenkins server installation and initial setup were successful.<\/p>

Conclusion<\/h2> Jenkins is a popular tool for automating software development. With its intuitive interface and flexible framework, users can deploy their applications to production environments much more quickly.<\/p>

Typically, software development presents its own set of challenges. One of them is ensuring that software is built, tested, and deployed in a timely manner and that any errors are fixed prior to the production phase. Jenkins is an open-source automation server for continuous integration (CI) and continuous delivery (CD) models. In other words, it […]<\/p>\n
