The Ultimate Guide to Set Up Your Git Server on Ubuntu and Increase Your Productivity
Greetings to all developers and tech enthusiasts! We all know that Git is one of the most popular version control systems out there. And if you are here, it’s because you want to learn how to configure Git server in Ubuntu. Well, you are in the right place! In this comprehensive guide, we will explain everything you need to know about how to configure Git server Ubuntu. From the basics to the advanced topics, we have it all covered. So, sit back, relax, and let’s dive in.
Introduction
Before we begin, let’s clarify what Git is. Git is a free and open-source distributed version control system that allows you to track changes in your code. It was created by Linus Torvalds in 2005 to manage the Linux kernel development. Since then, it has become the de-facto standard for version control in software development. Git allows you to work collaboratively with other developers on the same codebase, keeping track of changes made by each one of them.
In this guide, we will show you how to configure Git server on Ubuntu, so you can host your code repository locally. This will allow you to have full control over your code and collaborate with your team without relying on third-party services.
1. Prerequisites
Before we begin, make sure you have the following:
Software |
Version |
|---|---|
Ubuntu |
18.04 or later |
Git |
2.17.1 or later |
SSH |
Installed and configured |
You also need a user with sudo privileges, as we will install some packages and make system changes.
2. Setting Up the Git User
The first step is to create a user that will manage your Git repositories. This user should not have shell access, as it will only manage the Git service. To create the user, run the following command:
sudo adduser --system --shell /bin/bash --gecos 'Git Version Control' --group --disabled-password --home /home/git git
This command will create a system user called “git” with the necessary permissions to manage Git repositories. The home directory will be set to /home/git, and the shell will be set to /bin/bash.
3. Creating a Git Repository
The next step is to create a Git repository where you will store your code. We recommend creating a dedicated directory for your repositories, such as /home/git/repositories. To create the directory, run the following command:
sudo mkdir /home/git/repositories
Now, let’s create a repository inside this directory. For this example, we will create a repository called “myapp”:
sudo git init --bare /home/git/repositories/myapp.git
This command will create a bare Git repository at /home/git/repositories/myapp.git, which means it will not have a working directory. This is the standard way of setting up a Git server, as it only stores the Git objects and refs.
4. Configuring SSH Access
Now that we have a Git repository, we need to configure the SSH access so we can push and pull changes. For this, we will use the authorized_keys file, which stores the public keys of the users authorized to access the Git server.
First, we need to generate a key pair for the user that will access the server. To do this, run the following command:
ssh-keygen -t rsa -b 4096 -C "user@myapp.com"
This command will generate a new RSA key pair with a size of 4096 bits. Make sure to replace “user@myapp.com” with your email address.
Once the key pair is generated, we need to add the public key to the authorized_keys file. For this, run the following command:
sudo mkdir /home/git/.ssh
sudo touch /home/git/.ssh/authorized_keys
sudo chmod 700 /home/git/.ssh
sudo chmod 600 /home/git/.ssh/authorized_keys
sudo chown -R git:git /home/git/.ssh
These commands will create the .ssh directory and authorized_keys file inside the git user’s home directory. Then, it will set the correct permissions and ownership.
Now, open the authorized_keys file and add your public key. You can get your public key by running the following command:
cat ~/.ssh/id_rsa.pub
This will print your public key to the screen. Copy the entire key and paste it into the authorized_keys file:
nano /home/git/.ssh/authorized_keys
Save the file and exit the editor.
5. Testing the Connection
Now that everything is set up, let’s test the connection. From your local machine, run the following command:
ssh git@myapp.com
Replace “myapp.com” with your server IP or hostname. You should see a welcome message from Git.
6. Pushing and Pulling Changes
Now, let’s test pushing and pulling changes to the Git repository. First, let’s clone the repository:
git clone git@myapp.com:/home/git/repositories/myapp.git
This will create a working directory called “myapp” in your current directory.
Now, let’s create a new file and commit it:
cd myapp
touch newfile.txt
git add newfile.txt
git commit -m "Added newfile.txt"
Finally, let’s push the changes:
git push origin master
You should see the changes reflected in the Git server.
Advantages and Disadvantages of Setting Up a Git Server
