纯命令行linux下载太费劲了，安装一个ssh轻松一点，用windows下载，传输到linux后tar安装。
1.linux安装openssh(不记得具体的命令的，大概是这样 参考https://blog.csdn.net/qq_38701476/article/details/81135428)
sudo apt-get install openssh-server
2.su启动ssh
service ssh start
如果提示以下内容，则还需要生成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服务器第一次安装到Linux系统时，SSH主机密钥应该会自动生成以供后续使用。如果密钥生成过程没有成功完成，那就会导致这样的SSH登录问题。
解决方法：
在Debian、Ubuntu或其衍生版上，你可以使用dpkg-reconfigure工具来重新生成SSH主机密钥，过程如下：
- $ sudo rm -r /etc/ssh/ssh*key
- $ sudo dpkg-reconfigure openssh-server
3.获取linux本地IP地址，在其他机器上通过ssh访问该IP地址

在windows的cmd中访问
