利用ssh key实现Linux免密访问github

本文主要是介绍利用ssh key实现Linux免密访问github,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

1 生成ssh key,使用默认保存位置(注意要求输入密码时直接回车,否则每次要输密码)

[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 root@localhost.localdomain
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 将公钥文件/root/.ssh/id_rsa.pub上传到github


用记事本打开文件,然后拷贝内容到github


3 测试(切换为ssh方式,而不是默认的http方式)


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