是在ubuntu下出现的需求现笔记记录

apt-get update

更新源命令

apt-get install openssh-server

安装ssh服务

容易出现无法定位软件包。出现此问题是因为软件源没有更新可以尝试更新命令一试。或编辑etc/apt/source.list或sources.list ,添加源地址

如：

阿里云Ubuntu 18.04源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

还可以百度一下，查找源

然后apt-get update

更新

ps -e | grep ssh

检测ssh服务是否启动

看到有ssh字样就是启动了
