利用ssh key實現Linux免密訪問github

1 生成ssh key，使用默認保存位置（注意要求輸入密碼時直接回車，否則每次要輸密碼）

[root@localhost ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:CvE7bPPDYb1EnQsGsDjs8uqUoiW2XH8g36ycVixmJBw [e-mail]
The key's randomart image is:
+---[RSA 2048]----+
|      ..         |
|   E . ..        |
|  . * .  . . .   |
|   + =    + o    |
|  . = o S+ . .   |
|   = B =o o .    |
|o.+.* &o o .     |
|+=o.o+.Bo .      |
|.+o .=o ..       |
+----[SHA256]-----+
[root@localhost ~]#

2 將公鑰文件/root/.ssh/id_rsa.pub上傳到github


用記事本打開文件，然后拷貝內容到github


3 測試（切換為ssh方式，而不是默認的http方式）


[root@localhost boost_1_67_0]# git remote add origin [e-mail]:zzpu/boost.git
[root@localhost boost_1_67_0]# git push -u origin master
