实验室服务器docker里面ssh连不上，start-stop-daemon: matching on world-writable pidfile /run/sshd.pid is insecure

容器内提前安装了ssh

进入容器之后启动ssh

报错。说什么不安全（我不管，我就要连接，xkl还要跑深度学习，说如果我成功了，每天给我买一杯库迪咖啡）

注意修改权限的操作要在容器内，要是在ubuntu里面改错了权限，可能后果很严重

如果出现了下面的情况

 

（同样是在容器内。）就这样

root@7a034721befb:/#  chmod 600 /etc/ssh/ssh_host_ecdsa_key 
root@7a034721befb:/# chmod 600 /etc/ssh/ssh_host_ed25519_key
