Git的使用

源码安装

1. 访问地址：https://git-scm.com/download/linux
   https://mirrors.edge.kernel.org/pub/software/scm/git/

2. 找到最新版本的tar.gz包
   本次下载git-2.20.1.tar.gz

3. 安装git的依赖项
   [root@localhost ~]# yum -y install curl-devel expat-devel gettext-devel openssl-devel zlib-devel
[root@localhost yum.repos.d]# yum -y install gcc perl-ExtUtils-MakeMaker

4. 移除已安装的git
   [root@localhost ~]# yum remove git

5. 解压安装包
   [root@localhost ~]# tar -zxvf git-2.20.1.tar.gz

6. 进入解压目录，预编译git
   [root@localhost ~]# cd git-2.20.1
[root@localhost git-2.20.1]# ./configure --prefix=/usr/local/git

7. 编译并安装git
   [root@localhost git-2.20.1]# make && make install

8. 将git的脚本软连接到/usr/bin/目录下
   [root@localhost git-2.20.1]# ln -s /usr/local/git/bin/* /usr/bin/

9. 检测是否安装成功
   [root@localhost git-2.20.1]# git --version

全局配置
git config --global user.name "Administrator"
git config --global user.email "[email protected]"

与某远程仓库关联

• 创建一个新仓库
  git clone [email protected]:root/blank-project.git
cd blank-project
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master

• 在已存在的文件夹下
  cd existing_folder
git init
git remote add origin [email protected]:root/blank-project.git
git add .
git commit -m "Initial commit"
git push -u origin master

• 在已存在的仓库下
  cd existing_repo
git remote rename origin old-origin
git remote add origin [email protected]:root/blank-project.git
git push -u origin --all
git push -u origin --tags

本地与远程仓库不一致时拉取
git pull origin master --allow-unrelated-histories
