SSH登录断线时间：服务端修改 etc/ssh/sshd_config

# server每隔60秒发送一次请求给client，然后client响应，从而保持连接
ClientAliveInterval 60 

# server发出请求后，客户端没有响应得次数达到3，就自动断开连接，正常情况下，client不会不响应
ClientAliveCountMax 15 

生成sshkey

ssh-keygen -t rsa -b 2048 -C "<comment>"

配置自定义指定sshkey ~/.ssh/config

Host gitlab.com
    hostname gitlab.com
    User git
    IdentityFile ~/.ssh/deploy
