How to set up a Git server in CentOS 6.5 system

Git is an open source distributed version control system that is widely used in various software development projects. Building a Git server in the CentOS 6.5 system allows the team to better collaborate on development. Below I will introduce in detail how to set up a Git server in CentOS 6.5 system.

Step 1: Install Git

Installing Git in CentOS 6.5 system is very simple and can be installed directly through the yum command. Run the following command:

yum -y install git

After the installation is complete, run the following command to check whether Git is installed successfully:

git --version

If the version information of Git can be output, it means that Git has been successfully installed.

Step 2: Create a Git user

For security reasons, we can create a user specifically for running Git. Run the following command to create a user named git:

useradd git

Then set a password:

passwd git

Step 3: Create a Git repository

On the Git server, each project All require a Git repository to store code. We can create a Git repository on the server so that team members can share code.

First, create an empty directory in the directory where the code needs to be stored, for example:

mkdir -p /data/git/project.git

Then enter the directory and execute the following command:

cd /data/git/project.git
git init --bare

Among them, the --bare parameter It means that a bare warehouse is created, that is, there is no working directory, only the version information of the Git warehouse. This avoids problems such as synchronization difficulties.

Step 4: Set the permissions of the Git warehouse

In order to ensure the security of the Git warehouse, we need to set the correct permissions for it.

Run the following command to grant the git user read and write permissions on the project.git:

chown -R git:git /data/git/project.git

Then, run the following command to set the permissions of the warehouse:

chmod -R 755 /data/git/project.git

Step 5: Create Git user's SSH key

On the Git server, team members connect to the server through the SSH protocol, so an SSH key needs to be created for each member. Next we create an SSH key for the git user.

Execute the following command on the local terminal of the team member:

ssh-keygen -t rsa

Enter the name and password of the key as prompted. Then, copy the generated public key to the authorized_keys file on the Git server:

mkdir -p /home/git/.ssh
chmod 700 /home/git/.ssh
touch /home/git/.ssh/authorized_keys
chmod 600 /home/git/.ssh/authorized_keys
cat id_rsa.pub >> /home/git/.ssh/authorized_keys

In this way, we have successfully copied the public key to the Git server so that team members can connect to the server through the SSH protocol.

Step 6: Team collaboration

After creating the Git warehouse on the Git server, team members can connect to the server through the SSH protocol for code version control.

For example, team member Alice can clone the project .git on the Git server through the following command:

git clone git@yourdomain.com:/data/git/project.git

Then modify and submit the code:

git add *
git commit -m "Your commit message."
git push origin master

Other team members can also Code can be cloned and committed via similar commands.

During collaboration, problems such as code conflicts may arise, which need to be resolved through Git branches and merges. I won’t go into details here.

Summary

It is very simple to set up a Git server in CentOS 6.5 system. You only need to install Git, create a Git user, create a Git warehouse, set permissions, create SSH keys, collaborate and a series of operations. That’s it. As an open source distributed version control system, Git helps teams better collaborate on development and is one of the indispensable tools for every developer.
