1. 创建 www 用户

   useradd www

2. 建空仓库

   su www && cd /var/www
   sudo mkdir -p git/abc.git
   sudo chown -R www:www git
   cd git/abc.git
   git --bare init
   git update-server-info

   编辑config加入下面代码

   [receive]
       denyCurrentBranch = ignore

3. 客户端应用

   git clone ssh://user@ip/var/www/git/abc.git
   

4. 创建完毕裸版本库后还不能直接使用，首先要初始化版本库(例如增加一个文件)，不然会报错

   cd /var/www/html
   mkdir abc
   cd abc
   git init
   touch init_file
   git add init_file
   git commit -m "init"
   

5. 如果想在服务器版本库里面提交代码等操作，可以这样

   vi /var/www/html/abc/.git/config

   追加下面两项配置

   第一种：要求输入密码

   [remote "origin"]
       url = ssh://user@ip:/var/www/git/abc.git
       fetch = +refs/heads/*:refs/remotes/origin/*
   [branch "master"]
       remote = origin
       merge = refs/heads/master

   第二种：或者不输入密码

   [remote "origin"]
       url = /var/www/git/abc.git
       fetch = +refs/heads/*:refs/remotes/origin/*
   [branch "master"]
       remote = origin
       merge = refs/heads/master

   push到远端

   git push origin master

   从代码库中更新提交的修改

   git pull /var/www/git/abc.git

【扩展 1】开启 git http 访问

1. 安装fcgiwrap

   apt install fcgiwrap

   编辑配置

   vi /lib/systemd/system/fcgiwrap.service

   更改User和Group为：

   User=www
   Group=www

   重启

   systemctl daemon-reload
   service fcgiwrap restart
   

2. nginx 配置

   server {
       listen       80;
       listen   [::]:80;
       access_log /var/log/nginx/access_git-server.log;
       error_log  /var/log/nginx/error_git-server.log;
       server_name  git-server.mydomain.com;
   
       # htpasswd -bc /etc/nginx/auth.password usernameabc password123
       auth_basic "登录";
       auth_basic_user_file /etc/nginx/auth.password;
   
       location ~ (/.*) {
           fastcgi_pass unix:/var/run/fcgiwrap.socket;
           include fastcgi_params;
           fastcgi_param SCRIPT_FILENAME /usr/lib/git-core/git-http-backend;
           fastcgi_param GIT_HTTP_EXPORT_ALL "";
           fastcgi_param GIT_PROJECT_ROOT /dir/git;
           fastcgi_param PATH_INFO $1;
           fastcgi_param REMOTE_USER $remote_user;
       }
   
       error_page 404 /404.html;
           location = /40x.html {
       }
       error_page 500 502 503 504 /50x.html;
           location = /50x.html {
       }
   }

【扩展 2】推送现有文件夹到新仓库

1. 前往您的文件夹

   cd existing_folder

2. 配置 Git 仓库（test 换成自己新生成的仓库名称）

   git init --initial-branch=master --object-format=sha1
   git remote add origin [email protected]:/test.git
   git add .
   git commit -m "Initial commit"
   git push --set-upstream origin master
