純命令行linux下載太費勁了，安裝一個ssh輕松一點，用windows下載，傳輸到linux后tar安裝。
1.linux安裝openssh(不記得具體的命令的，大概是這樣 參考https://blog.csdn.net/qq_38701476/article/details/81135428)
sudo apt-get install openssh-server
2.su啟動ssh
service ssh start
如果提示以下內容，則還需要生成key才可以
Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_ecdsa_key Could not load host key: /etc/ssh/ssh_host_ed25519_key

oenSSH服務器第一次安裝到Linux系統時，SSH主機密鑰應該會自動生成以供后續使用。如果密鑰生成過程沒有成功完成，那就會導致這樣的SSH登錄問題。
解決方法：
在Debian、Ubuntu或其衍生版上，你可以使用dpkg-reconfigure工具來重新生成SSH主機密鑰，過程如下：
- $ sudo rm -r /etc/ssh/ssh*key
- $ sudo dpkg-reconfigure openssh-server
編輯 sshd_config，（這個是server的配置，ssh_config是client的配置）
root@Yzz:/etc/ssh# vi sshd_config
我忘了具體這行怎么寫了，反正是密碼認證
passwordAuthxxxxxxx yes
3.獲取linux本地IP地址，在其他機器上通過ssh訪問該IP地址
root@Yzz:/etc/ssh# ifconfig
