OpenResty/Nginx设置TCP/UDP端口转发

TCP/UDP端口转发配置示例：
~/nginx.conf文件末尾添加配置代码：

stream {
    include /etc/nginx/conf.d/*.stream;
}

或

stream {
    include /usr/local/openresty/nginx/conf/conf.d/*.stream;
}

conf.d目录下，添加*.stream后缀的配置文件，并编辑配置：

tcp.stream 文件：
#同时监听ipv4及ipv6的88端口并转发到本地localhost的80端口
server {
    listen 88;
    listen [::]:88;
    proxy_connect_timeout 5s;
    proxy_timeout 20s;
    proxy_pass localhost:80;
}
#将udp 53端口转发到192.168.1.23 53端口
server {
    listen 88 udp reuseport;
    listen [::]:88 udp reuseport;
    proxy_timeout 20s;
    proxy_pass localhost:80;
}
