Nginx Stream 四层代理配置笔记

阅读时长: 2 分钟

nginx 4层代理(初级版)

Nginx从1.9.0版本开始,新增加了一个stream模块,用来实现四层协议的转发、代理或者负载均衡

本笔记使用的 Nginx 1.16.1 软件包动态加载了 stream 模块。不同安装包的模块配置需要分别检查。

http://nginx.org/en/docs/stream/ngx_stream_core_module.html

暂不需要编译源码 http://nginx.org/en/download.html

遇到问题:以下都是环境上缺少相关的依赖,安装即可

有两个模块能达到效果:

  • ngx_stream_proxy_module
  • ngx_stream_core_module
