如何在CentOS 7上安裝git

檢查Git是否已安裝：運行git --version，若提示命令未找到則表示未安裝；2. 使用yum安裝Git：執行sudo yum install git -y命令從默認倉庫安裝；3. 驗證安裝：再次運行git --version確認安裝成功並查看版本；4. 配置Git：可選但推薦設置用戶名和郵箱，使用git config --global user.name "Your Name"和git config --global user.email "you@example.com"；5. 安裝較新版本Git：若需Git 2.x版本，先安裝IUS倉庫sudo yum install https://repo.ius.io/ius-release-el7.rpm -y，再安裝git2u包sudo yum install git2u -y，最後通過git --version驗證版本升級成功，Git即可在CentOS 7系統上正常使用。

Installing Git on CentOS 7 is straightforward and can be done using the system's package manager, yum . Here's how you can do it step by step.

Check if Git is already installed

Before installing, verify whether Git is already present on your system:

 git --version

If Git is not installed, you'll see a command not found error. Otherwise, it will display the installed version.

Install Git using yum

CentOS 7 includes Git in its default repositories, so you can install it directly with yum :

 sudo yum install git -y

This command installs the latest version of Git available in the CentOS 7 repository.

Verify the installation

After installation, confirm that Git was installed correctly:

 git --version

You should see output like:

 git version 1.8.3.1

(Note: The version in CentOS 7's default repo is somewhat older. If you need a newer version, consider compiling from source or using a third-party repo.)

Configure Git (Optional but recommended)

Once installed, set up your user name and email address, which Git uses for commit identification:

 git config --global user.name "Your Name"
git config --global user.email "you@example.com"

You can verify your settings with:

 git config --list

(Optional) Install a newer version of Git

If you need a more recent version than what's in the default CentOS 7 repo (eg, Git 2.x), you can enable the IUS repository and install from there:

1. Install the IUS repository:

    sudo yum install https://repo.ius.io/ius-release-el7.rpm -y

2. Install the newer Git package:

    sudo yum install git2u -y

3. Verify the version:

    git --version

   This should give you a much newer version of Git (eg, 2.30 ).

   That's it. Git is now installed and ready to use on your CentOS 7 system.
