本方式基于SSH，认证基于Linux的用户体系，服务器上用户A有一个Git Repo，需要使用A的密钥进行clone/push等操作。所以对安全性要求高的话，建议单独建立一个没有sudo权限的git用户：Linux用户管理

# 在服务器上创建Repo，注意init的时候要使用--bare创建裸仓库
# 这样创建的仓库可以被其他主机clone/push等，但是在（服务器）本地无法像普通的Repo一样访问
# 裸仓库是专门用作远程仓库推送/拉取用的，没有工作区（即没有实际的源代码文件），结构略有不同
# 普通仓库不能当作远程仓库被其他人 push。只有 裸仓库 才能接受其他仓库推送（避免工作区冲突）
# 注意文件夹的命名，后面有.git

提供了Web界面，好像可以使用Docker
