Installing GitBucket on CentOS 8

GitBucket is an open-source, web-based Git platform written in Scala. It provides a GitHub-like user interface and functionality, allowing developers to create, manage, and collaborate on Git repositories. GitBucket is designed to be easy to use and deploy, making it a popular choice for individuals and small teams.

Prerequisites

Before you can install GitBucket on CentOS 8, there are a few prerequisites that need to be met:

• A CentOS 8 server with root access
• Java Development Kit (JDK) 8 or above

Step 1: Install Java Development Kit (JDK)

First, update the package index on your CentOS 8 server:

sudo dnf update

Then, install the OpenJDK package using the following command:

sudo dnf install java-11-openjdk-devel

Step 2: Download and Configure GitBucket

Go to the GitBucket releases page on GitHub and look for the latest release. Copy the download link for the WAR file (ending with ".war"):

wget https://github.com/gitbucket/gitbucket/releases/download/[version]/gitbucket.war

Replace "[version]" with the actual version number of GitBucket.

Next, create a directory to store the GitBucket WAR file:

sudo mkdir /var/gitbucket

Move the downloaded WAR file to the newly created directory:

sudo mv gitbucket.war /var/gitbucket

Now, create a systemd service file to manage the GitBucket service:

sudo nano /etc/systemd/system/gitbucket.service

Paste the following configuration into the file:

[Unit]
Description=GitBucket
After=syslog.target

[Service]
ExecStart=/usr/bin/java -jar /var/gitbucket/gitbucket.war
User=git
Type=simple
Restart=always

[Install]
WantedBy=multi-user.target

Save and close the file when you are finished.

Step 3: Create a GitBucket User

To enhance security, it is recommended to run GitBucket under a dedicated user. Create a new user called "git" using the following command:

sudo useradd -r -d /var/gitbucket -M -s /sbin/nologin git

Step 4: Start and Enable GitBucket

Start the GitBucket service using the following command:

sudo systemctl start gitbucket

Enable the GitBucket service to start automatically at boot:

sudo systemctl enable gitbucket

Step 5: Configure Firewall

If you have the firewall enabled on your CentOS server, you need to allow connections to the GitBucket port. By default, the GitBucket port is set to 8080. Run the following command to open the port:

sudo firewall-cmd --permanent --add-port=8080/tcp

Reload the firewall configuration for the changes to take effect:

sudo firewall-cmd --reload

Step 6: Access GitBucket Web Interface

You can now access the GitBucket web interface by opening your web browser and navigating to http://:8080/.

Remember to replace "" with the actual IP address or domain name of your server.

On the first visit, you will be prompted to set up an initial administrator account. Follow the on-screen instructions to complete the setup process.

Congratulations! You have successfully installed GitBucket on CentOS 8. You can now start creating and managing Git repositories using the GitBucket web interface.
