ssh 公钥生成

生成, 默认文件名为id_rsa

ssh-keygen -t rsa -C "your_email@example.com"

多个key的情况, second为文件名称

ssh-keygen -t rsa -C "your_email@example.com" -f ~/.ssh/second

服务端配置

将生成的xxx.pub的内容拷贝到对应的网站中

ssh config 配置. ~/.ssh/config

• Host >域名
• User >用户名
• IdentityFile >ssh key的路径
• IdentitiesOnly >只使用这里设置的key, 防止使用默认的
• ServerAliveInterval >连接保持
• ControlMaster auto >不用重新登录
• ControlPath ~/.ssh/master-%r@%h:%p
