How to Install Gerrit on Fedora CoreOS Latest

Gerrit is a web-based code review tool that facilitates team collaboration on code changes. It is widely used in many development teams to improve code quality and accelerate development cycles. If you are using Fedora CoreOS Latest and want to install Gerrit, this tutorial will guide you through the process step by step.

Prerequisites

Before you start, make sure you have the following prerequisites:

  • Fedora CoreOS Latest installed on your system
  • A terminal emulator application (e.g., gnome-terminal, xterm, konsole, etc.)
  • Root or sudo privileges

Also, make sure your system is up to date by running the following command:

sudo dnf update

Step 1: Install Java

Gerrit requires Java to run. To install Java on your system, run the following command:

sudo dnf install java-11-openjdk-devel

This command will install the OpenJDK 11 development package, which includes both the JRE and the JDK.

Step 2: Install Git

Gerrit uses Git to manage code repositories. If Git is not installed on your system, run the following command to install it:

sudo dnf install git

Step 3: Download Gerrit

Go to the official Gerrit website (https://www.gerritcodereview.com/) and download the latest stable version of Gerrit. Once you have downloaded the file, extract it to your preferred location. For example, if you want to extract it to the /opt directory, run the following command:

sudo tar -xvf gerrit-3.*.tar.gz -C /opt/

Make sure to replace the * with the specific version of Gerrit you downloaded.

Step 4: Configure Gerrit

To configure Gerrit, navigate to the Gerrit installation directory and run the following command:

java -jar bin/gerrit.war init --batch --install-all-plugins

This command will initialize Gerrit and install all necessary plugins. During the initialization process, you will be prompted to answer several questions about the Gerrit configuration. You can use the default values for most of the questions by pressing Enter. However, you should pay attention to the following questions:

  • Site URL: Enter the URL that users will use to access Gerrit (e.g., http://192.168.0.1:8080).
  • SSHD port: Enter the port number for the SSH daemon (e.g., 29418).
  • SMTP server hostname: Enter the hostname or IP address of your SMTP server.
  • SMTP server port: Enter the port number for your SMTP server (e.g., 587).
  • SMTP username: Enter the username for your SMTP server (if required).
  • SMTP password: Enter the password for your SMTP server (if required).
  • SMTP encryption: Enter the encryption method for your SMTP server (e.g., TLS).

After answering all questions, Gerrit will be configured and ready to start.

Step 5: Start Gerrit

To start Gerrit, navigate to the Gerrit installation directory and run the following command:

java -jar bin/gerrit.war daemon

This command will start the Gerrit daemon, which listens on the configured port and waits for incoming requests.

Step 6: Access Gerrit

Once Gerrit is started, you can access it by navigating to the Site URL you configured earlier (e.g., http://192.168.0.1:8080) in your web browser. You will be prompted to create a new user account or log in with an existing one.

Congratulations! You have successfully installed Gerrit on Fedora CoreOS Latest. Now you can use it to manage code repositories and collaborate with your team on code changes.
