How to compile and install git on Linux platform

Using Git for code version management in a Linux system is a very important task, because Git has powerful branch management functions and fast code version management capabilities. Although many Linux distributions come with a precompiled version of Git, compiling Git yourself is a safer and more reliable approach, especially since many Linux distributions do not come with a precompiled version of Git. Moreover, compiling Git yourself also provides flexibility for different platforms.

Compiling and installing Git on the Linux platform is not complicated. You only need to follow the following steps:

Step 1: Install the necessary dependencies

Before doing Git Before compiling and installing, you need to install some necessary dependencies.

Execute the following command to install the required dependencies in Ubuntu or Debian distribution:

sudo apt-get update
sudo apt-get install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-ExtUtils-MakeMaker autoconf

Install the required dependencies in CentOS or RHEL distribution:

sudo yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-ExtUtils-MakeMaker autoconf

Step 2: Download and decompress the Git source code

Before continuing to compile and install Git, you need to download the Git source code first.

Execute the following command to download the source code of Git:

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.33.0.tar.gz

Among them, the version number at the end of the link will change as Git is updated.

After the download is completed, execute the following command to decompress the downloaded source code:

tar -xvzf git-2.33.0.tar.gz

Step 3: Compile and install Git

After the preparations are completed, you can start Compile to install Git. Switch to the Git source code directory and execute the following commands to compile and install:

cd git-2.33.0
make prefix=/usr/local/git all
sudo make prefix=/usr/local/git install

The above command will install Git in the /usr/local/git directory. If you need to change the installation directory, you can modify the prefix parameter.

Step 4: Add Git to the system environment

After successfully installing Git, you need to add the Git path to the system environment variable in order to use Git commands in the terminal.

Execute the following command to add the Git path to the system environment variable:

echo 'export PATH=$PATH:/usr/local/git/bin' >> ~/.bashrc
source ~/.bashrc

Step 5: Test Git

Execute the following command to test whether Git is installed successfully:

git --version

After successfully executing the above command, the Git version number information will be displayed, indicating that Git has been successfully compiled and installed.

Summary

The above is the process of compiling and installing Git on the Linux platform. In this process, you need to install dependencies, download and decompress the Git source code, compile and install Git, add Git to the system environment, and test Git. If you encounter errors or exceptions, you can view the output information during the installation process or execute the "make clean" command to recompile.

In general, using Git for code version management is very important. Compiling and installing Git yourself can improve code security and reliability, while also providing flexibility for different platforms.
