shell 端口映射

在Shell中，可以使用ssh命令实现端口映射。通过ssh命令的-L选项，可以将本地端口映射到远程主机上的指定端口。例如，使用以下命令将本地的9987端口映射到远程主机10.154.62.197的3306端口上：

ssh -CfNg -L 9987:10.154.62.197:3306 root@localhost -p 9999

这意味着，当在本地访问9987端口时，实际上访问的是远程主机上的10.154.62.197的3306端口。同样地，可以使用类似的命令进行多个端口的映射。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
