Liunx 服务器添加 SSH 访问Git / CentOs

1、看看目录是否存在

ls -al ~/.ssh

2、生成密钥

ssh-keygen -t rsa -C "[email protected]"

操作

Enter file in which to save the key (/home/qy/.ssh/id_rsa):  #【按回车】
Enter passphrase (empty for no passphrase): #【输入密码】
密码 ****
Enter same passphrase again: # 【再次输入密码】
密码 ****

密钥文件目录

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:joUMKG8+3KkO8dbpRyvHYgOG8ufydZNL3jkMYYB6mO8 [email protected]
The key's randomart image is:
+---[RSA 2048]----+
|     .           |
|   .. .          |
|. .+.  .         |
| o+ .o .o        |
|..oo  o.S.       |
|o*oo.o.+..       |
|oo*o=oo.*o       |
| oo+E.=+ +o.     |
| .o*+*  o o.     |
+----[SHA256]-----+

3、得到 agent pid

eval $(ssh-agent -s)

输出

Agent pid 22939

4、将 ssh 私钥添加到 ssh 代理中。如果使用不同的名称创建了密钥, 或者添加了具有不同名称的现有密钥, 请用私钥文件的名称替换该命令中的 id_rsa

ssh-add ~/.ssh/id_rsa

5、复制 SSH key 到剪切板

6、到Git 添加公钥

7、服务器确认

gitee 的

ssh -T [email protected]

github的

ssh -T [email protected]
