服务器端 ----> 使用frps搭建服务
下载编译安装frp
下载：
wget https://github.com/fatedier/frp/releases/download/v0.44.0/frp_0.44.0_linux_amd64.tar.gz
tar -zxvf frp_0.44.0_linux_amd64.tar.gz
cd frp_0.44.0_linux_amd64/修改frps.ini为如下：
[common]
bind_port = 8090
vhost_http_port = 8090具体服务器端详细配置参考这里：服务端配置 | frp (gofrp.org)
开放8090端口：
sudo iptables -I INPUT -p tcp --dport 8090 -j ACCEPT(或者在宝塔面板中开放8090端口)
在云服务器设置防火墙中打开端口开发板使用mjpg-streamer+frpc搭建客户端
