Nginx反代代理MySQL配置实例
案例:一个朋友要用Nginx代理MySQL(MySQL局域网),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
--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:
--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:
配置:
stream {
upstream mysql {
zone myapp1 64k;
server localhost:3306 weight=1 max_fails=3 fail_timeout=30s;
#server 192.168.1.221:3306 weight=1 max_fails=2 fail_timeout=30s;
}
server {
listen 2188;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass mysql;
}
}
检测:
[root@autoCentOS67X64 conf]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@autoCentos67X64 conf]#
启动:
[root@autoCentos67X64 conf]# netstat -atupn|grep nginx
tcp 0 0 0.0.0.0:2188 0.0.0.0:* LISTEN 2359/nginx
[root@autoCentos67X64 conf]#
4、验证:
[root@log~]# mysql -uroot -prenzhiyuan -h 192.168.1.11 -P2188

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。
