Git 服务器搭建
http://www.runoob.com/git/git-server.html

如果服务器 ssh 访问需要秘钥，那么Git 仓库访问也需要进行相应配置。

1，将自己的公钥给到服务器，添加到服务器对应的 known_hosts 中；

• 如果自己没有公钥和私钥，那么可以自己生成：
  ssh-keygen -t rsa -C "ribuluo000@163.com"

  .ssh  ssh-keygen -t rsa -C "ribuluo000@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/nick/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/nick/.ssh/id_rsa.
Your public key has been saved in /Users/nick/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:pL1AYGrQ2Yg+6JASVSr3DWrsaP3uNsWPZRZlEM/dAs8 ribuluo000@163.com
The key's randomart image is:
+---[RSA 2048]----+
|.+.=+    oo.     |
|o.++..    oo= .  |
|+o= . . . oo E . |
|=B o + + .    .  |
|+ = . = S .      |
| =.    + =       |
|....  . B        |
|.   .o . .       |
|    ++.          |
+----[SHA256]-----+
  .ssh

生成过程中需要设置自己私钥的密码，请牢记。

• 服务器将收到的公钥放入对应的 known_hosts 中：
  cat my_id_ras.pub >> authorized_keys

2,本地配置ssh

在本地 .ssh 目录下，找到 config 文件，如果没有，则创建；
将以下配置代码放进去：

# ------ 官网 ------
Host        120.55.17.17
HostName     120.55.17.17
    Port     1666
    User     usergit
    IdentityFile    ~/.ssh/id_rsa
# ------ 官网结束 ------
