Ubuntu安装配置SSH服务

每次安装好Ubuntu之后就要配置SSH服务，每次配置SSH服务都还记不住命令，无奈只有写篇文章方便以后查看。

Ubuntu安装好后默认是没有安装SSH服务的，需要我么手动安装配置SSH。

1	ansheng@ansheng-me:~$ sudo apt-get install openssh-server

貌似默认自带的就有客户端，如果没有就安装

1	ansheng@ansheng-me:~$ sudo apt-get install openssh-client

1	ansheng@ansheng-me:~$ sudo systemctl start ssh.service

ansheng@ansheng-me:~$ sudo netstat -tlnp | grep "22"

tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 3735/sshd

tcp6 0 0 :::22 :::* LISTEN 3735/sshd

ansheng@ansheng-me:~$ sudo systemctl enable ssh.service

Synchronizing state of ssh.service with SysV init with /lib/systemd/systemd-sysv-install...

Executing /lib/systemd/systemd-sysv-install enable ssh

ansheng@ansheng-me:~$ ssh 127.0.0.1

ECDSA key fingerprint is SHA256:8KZ4QUV0YNp2c487rOalUMuVD44aHDnTHwCwQ6H6HCE.

Are you sure you want to continue connecting (yes/no)?

出现这个提示就完成了
