Nginx Upstream Resolver, For older versions or specific cases, you can This module also allows nginx to start if an upstream contains a defunct domain name that no longer resolves. In the realm of server management and 一、核心原理与架构设计 1. 之前写了篇文章用openresty实现了一个动态路由，虽然说是动态的，但是实际上还是需要将upstream在配置文件中写好，还是相当于静态的。最近工作中有这方面的需求，upstream是完 nginx中如何利用resolver实现动态upstream呢？首先了解下resolver，在nginx中，nginx有一套自己的域名解析过程，在nginx配置中，通过resolver指令来设置DNS Introduction The NGINX upstream module is a pivotal feature within NGINX, an incredibly popular web server and reverse proxy tool. Nginx is a multiplexing server (many connections in one OS process) and each In Nginx Open Source, to dynamically resolve upstream name, you need to use variable in proxy_pass directive from within the " server block " as shown below instead of using upstream Nginx, a high-performance HTTP server and reverse proxy, includes a feature called the resolver. With the growing adoption of microservices Nginx resolver is playing very important part in creating fault tolerant setups, especially when it comes to the free open source version. With the growing adoption of microservices Nginx upstream blocks provide a powerful and flexible way to distribute traffic across multiple backend servers. In order for this parameter to work, the resolver directive must be specified in the http block or in the corresponding upstream block. By understanding how to configure these 10 "Resolver" parameter defines the location of DNS server that nginx must use in order to resolve the IP of the URL passed under proxy_pass; As explained by Tarun, by default nginx will The Nginx resolver directive is necessary because the OS resolver is not asynchronous. See here for more detail .
