openresty ngx_http_upstream_check_module 模块安装

本文主要是介绍openresty ngx_http_upstream_check_module 模块安装，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

实际上测试了tengine以及其他的ngx_http_upstream_check_module发现都不好使，反而发现ngx_healthcheck_module 值得使用

构建

基于docker，复用了openresty 官方的dockerfile 构建模式，核心流程如下
clone ngx_healthcheck_module 模块，patch 布丁到openresty，执行构建

• dockerfile
  集成了部分tengine的模块

}

• 效果
  当然直接prometheus metrics 可以直接使用

 

 

说明

我已经构建好了一个镜像，可以直接使用dalongrong/openresty-tengine:latest，还是得吐槽下tengine了问题不少，而且基本不维护了（好像今年又要开始维护了。。。。）,如果为了方便监控，推荐也集成上nginx 的vts模块,真得好好学学nginx 模块开发了，不然解决问题就有点费事了
