问题 I have a running node server which listens on 3 different ports. I have three different subdomains of a url pointing to port 80 of the server on which node is running/listening. What I am trying to do is proxy pass a request from a sub-domain to its respective port using haproxy . My node server is dockerized with the ports exposed on the host. I can hit them individually using the server's IP address on their port so they seem to be running fine. My haproxy will also be running inside a

use environment variables in haproxy

由 北城余情 提交于 2019-12-13 15:39:14
问题 Hoping someone can point me in the right direction. I am trying to configure HAProxy to use an environment variable (from the operating system) as part of an acl statement. So if the environment variable is set to true when HAProxy is started or reloaded then access is granted. If the environment variable is set to false then I would just want the NOSVR error to be generated. I know that if I also put in a rule that says use_backend ftp1-srv unless accessFtp then the request goes through OK

Haproxy搭建Web群集概述

博文目录 一、Haproxy概述 1、HTTP请求 2、负载均衡常用调度算法 3、常见的Web群集调度器 二、Haproxy配置项介绍 1、global配置项通常有下面配置参数： 2、defaults配置项配置默认参数，一般会被应用组件继承，如果在应用组件中没有特别的声明，将安装默认配置参数： 3、listen配置项一般配置应用模块参数： 三、Haproxy的参数优化 一、Haproxy概述 Haproxy是目前比较流行的一种群集调度工具，同类群集调度工具有很多，如LVS和Nginx。相比较而言，LVS性能最好，但是搭建相对复杂；Nginx的upstream模块支持群集功能，但是对群集节点健康检查功能不强，性能没有Haproxy好。Haproxy官方网站是 http://www.haproxy.org/ 。 1、HTTP请求 通过URL访问网站使用的协议是HTTP协议，此类请求一般称为HTTP请求。HTTP请求的方式分为GET方式和POST方式。 当使用浏览器访问某一个URL，会根据请求URL返回状态码，通常正常的状态码为2 X X、3 X X（如200、301），如果出现异常会返回4 X X、5 X X（如400、500）。例如：访问http://www.test.com/a.php?ld=123 ，就是一个GET请求，如果访问正常，会从服务器的日志中获取200状态码

问题 We have a real-time service, which gets binary messages from different sources (internal and external), then using a couple of NodeJS instances and one HAProxy instance, configured to route TCP traffic, we deliver them to our end-users and different services who consume the messages. HAProxy version is 1.8.14, NodeJS is 6.14.3, both hosted on a CentOS 7 machine. Now we've got a complex problem with some "burst"s in the outbound interface of HAProxy instance. We are not sure whether the burst
