ubuntu 16 打开SSH服务

1.查看是否启动进程

roott@jiqing-virtual-machine:~# ps -ef | grep sshd

root       3477      1  0 18:36 ?        00:00:00 /usr/sbin/sshd -D

root       3478   3477  0 18:36 ?        00:00:00 sshd: root@pts/1

root       3552   2265  0 18:37 pts/3    00:00:00 grep --color=auto sshd

2.如果没有，安装ssh-server

apt-get install openssh-server

3.启动ssh

/etc/init.d/ssh start

4.开启root登录

sudo vi /etc/ssh/sshd_config

PermitRootLogin yes

5.自动接受新的公钥

sudo vi /etc/ssh/ssh_config

StrictHostKeyChecking no

7.重新启动

/etc/init.d/ssh restart

或

sudo service ssh restart
