SSH免密登入

1、客戶端生成公鑰、私鑰

[email protected] MINGW64 ~
$ cd ~     //進入家目錄

[email protected] MINGW64 ~
$ rm -r .ssh                             //刪除原先的目錄.ssh
rm: cannot remove '.ssh': No such file or directory

[email protected] MINGW64 ~
$ ssh-keygen -t rsa -C 
 
[email protected]                         //生成公鑰、私鑰
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/yang/.ssh/id_rsa):
Created directory '/c/Users/yang/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/yang/.ssh/id_rsa.
Your public key has been saved in /c/Users/yang/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:pPSUKaoux0qw9t66ynPdkt2FOn0vNISfZx+v6H5MAIE

The key's randomart image is:

2、伺服器端配置公鑰

3、驗證免密登入

[email protected] MINGW64 /d/GitWorkSpace/weChat (master)
$ vim test.txt                                            //編輯檔案

[email protected] MINGW64 /d/GitWorkSpace/weChat (master)
$ git add test.txt                                   //暫存

[email protected] MINGW64 /d/GitWorkSpace/weChat (master)
$ git commit -m "test ssh for remote" test.txt                   //提交到本地庫
