Config

systemctl daemon-reload
systemctl enable frpc
systemctl status frpc
systemctl enable frps
systemctl status frps

想问下 After=network.target 时什么意思? 是指 网络启动好之后就行嘛。不需要用户名密码登录。
问这个问题的场景是这样： 装 frpc机器是不连显示器的。有时候重启还需要接显示器登录之后。fprc才启动。
理想情况是，断电重启后.frpc客户端就自动连上了。远程就可以 ssh了。

不要忘了这一句 sudo systemctl daemon-reload

frpc.service 可以加一句：

ExecReload=frpc reload

前提是 frpc.ini 中有设定 admin_port。
