Nginx反代MySQL案例
案例：一个朋友要用Nginx代理MySQL（MySQL局域网），不用VPN，不用NAT映射等，好吧，做个笔记。Nginx版本：1.9.x（持tcp的负载均衡，nginx_tcp_proxy_module（姚伟斌阿里团队也可以实现））
Nginx官方模块： ngx_stream_core_module --with-stream_ssl_module（ssl协议支持，比如MySQL ssl）
官网：http://nginx.org/en/docs/stream/ngx_stream_core_module.html
1、查看现有编译
1
--user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module
2、重新编译：
1
--user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module --with-stream --with-stream_ssl_module
注意：--with-stream --with-stream_ssl_module
3、配置、检测、重启nginx：

}
server {
listen 2188;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass mysql;
}
}

注意：2188可是Nginx的端口，代理（负载）后端的MySQL。其它玩法大家可自己研究。
