命令行界面登录ssh

1、使用命令行查看安装地址

(base) dghcs:~ tudghian$ whereis ssh
/usr/bin/ssh

2、查看当前电脑的ssh行程

(base) dghcs:~ tudghian$ ps aux | grep ssh
tudghian         20518   1.5  0.0  4278296    840 s000  S+    3:36下午   0:00.01 grep ssh

可以看出并没有ssh进程，因为没有打开mac的远程登录功能

打开系统偏好设置
在这里插入图片描述
打开共享
勾选左边两个选项

3、使用命令ssh localhost查看

(base) dghcs:~ tudghian$ ssh localhost
The authenticity of host 'localhost (::1)' can't be established.
ECDSA key fingerprint is SHA256:PIZ12342cRa3cA7uV4M88abHzqKI.
Are you sure you want to continue connecting (yes/no)? yes

4、使用命令登陆服务器输入密码登陆！！！大告成功

(base) dghcs:~ tudghian$ ssh -p 22 root@11.279.1250.73
