ed25519 密钥（推荐）

关于 ed25519 与 rsa 的区别，参考：Enhance Security of your SSH Keys with ed25519 Algorithm (opens new window)

ssh-keygen -m PEM -t ed25519 -C "[email protected]"

• ~/.ssh/id_ed25519 ：私钥
• ~/.ssh/id_ed25519.pub ：公钥

RSA 密钥（弃用）

ssh-keygen -t rsa -C "[email protected]"
# 存放的路径在操作提示有

• id_rsa ：私钥
• id_rsa.pub ：公钥

扩展

GitHub 设置 SSH

默认认为，已经上传公钥等操作

ssh -T [email protected]
# 拉取[email protected]:xxxxx
# ssh -T [email protected]

# git clone [email protected]:xxxxx  注意不是 https://github.com/NipGeihou/xxxx.git

指定密钥连接 SSH

方法一：

ssh -i /root/.ssh/id_rsa -T [email protected]

方法二：

vim /root/.ssh/config

Host gitee gitee.com
    HostName gitee.com
    IdentityFile /root/.ssh/id_rsa2
    User root

配置模板：

点击查看

Host myshortname realname.example.com
    HostName realname.example.com
    IdentityFile ~/.ssh/realname_rsa # private key for realname  这个注释要去掉，否则会报错
    User remoteusername

Host myother realname2.example.org
    HostName realname2.example.org
    IdentityFile ~/.ssh/realname2_rsa  # different private key for realname2
    User remoteusername
