日期及版本:2014.5.4v1.0 架构图 实验目的: 1.Haproxy+Keepalived双主双机高可用模型,keepalived为Haproxy主从提供高可用保证haproxy-master若挂掉haproxy-backup能无缝接管,haproxy为后端Web提供负载均衡,缓解并发压力,实现WEB站点负载均衡+高可用性: 2. Haproxy反代web做动静分离: 3. Haproxy反代mysql 算法leastconn和roundrobin的不同效果: 系统环境: OS:cent

【重要】Nginx实现HTTP负载均衡和TCP负载均衡

说明:很简单一个在HTTP模块中,而另外一个和HTTP 是并列的Stream模块(Nginx 1.9.0 支持) 一.两个模块的最简单配置如下 1.HTTP负载均衡: http { include mime.types; default_type application/octet-stream; upstream live_node { server 127.0.0.1:8089; server 127.0.0.1:8088; } server { listen 80; server_name

Nginx负载均衡和LVS负载均衡的比较分析 作者:匿名 来源:ChinaZ源码报导 浏览:1032次 2011-12-6 15:12:27 字号:大 中 小 [摘要]Nginx是一个高性能的 HTTP 和 反向代理 服务器,也是一个 IMAP/POP3/SMTP 代理服务器.本文介绍Nginx负载均衡和LVS负载均衡的比较分析. LVS和Nginx都可以用作多机负载的方案,它们各有优缺,在生产环境中需要好好分析实际情况并加以利用. 首先提醒,做技术切不可人云亦云,我云即你云:同时也不可太趋向保

负载均衡总结(四层负载与七层负载的区别)

https://www.jianshu.com/p/9826d866080a 1. 什么是负载均衡 负载均衡 建立在现有网络结构之上,它提供了一种廉价有效透明的方法扩展网络设备和服务器的带宽.增加吞吐量.加强网络数据处理能力.提高网络的灵活性和可用性. 2. 负载均衡分类 负载均衡根据所采用的设备对象(软/硬件负载均衡),应用的OSI网络层次(网络层次上的负载均衡),及应用的地理结构(本地/全局负载均衡)等来分类.本文着重介绍的是根据应用的 OSI 网络层次来分类的两个负载均衡类型. 我们先来看

nginx负载均衡和lvs负载均衡的比较分析

一.lvs的优势: 1.抗负载能力强,因为lvs工作方式的逻辑是非常之简单,而且工作在网络4层仅做请求分发之用,没有流量,所以在效率上基本不需要太过考虑.在我手里的 lvs,仅仅出过一次问题:在并发最高的一小段时间内均衡器出现丢包现象,据分析为网络问题,即网卡或linux2.4内核的承载能力已到上限,内存和 cpu方面基本无消耗. 2.配置性低,这通常是一大劣势,但同时也是一大优势,因为没有太多可配置的选项,所以除了增减服务器,并不需要经常去触碰它,大大减少了人为出错的几率. 3.工作稳定,因为

Nginx学习笔记06负载均衡之(一)负载均衡介绍

1.1.1. 负载均衡的介绍 Nginx中使用upstream配置块,可以方便的配置出一个基于反向代理的负载均衡解决方案. 在upstream中可以包含多个server配置项,每个server配置项指定一个主机地址和端口号,代表一个主机(上游服务器). 在proxy_pass配置反向代理时,可以不指定最终的主机地址,而是只指定upstream配置块指定的引用名称.在本文中,upstream配置了一个包含三个主机地址的负载均衡主机集群. 配置内容: http { include       mim

windows第四层负载均衡--基于NLB负载均衡

上面有一篇文章说windows第七层负载均衡,这次讲讲第四层负载均衡 TCP/IP协议族,第七层是应用层,第四层是传输层.第四层负载均衡主要通过IP进行转化. 一些优秀的第四层负载均衡软件,速度可以接近硬件负载均衡的效率.当然,论速度还是人家硬件的快一点点,毕竟人家那价格摆在那里,一台F5,十几万,几十万,上百万不等. 第四层重与第七层相比:优秀就是速度快,能感知集群服务器的状态.缺点就是不能感知应用层软件的状态,比如IIS站点挂掉,但是如果服务器没有挂掉,转化流量用继续流入该服务器. 现在很多

nginx+2tomcat的负载均衡环境,负载均衡策略用权重形式

1 安装jdk 2 安装两个tomcat,修改两个tomcat中端口号 3 安装nginx,并配置nginx,其中10001,20001是tomcat端口号,8044是nginx端口号:weight是设置权重 4 修改两个tomcat中的index.jsp文件,随便改点内容,以便访问时区分 5 重启两个tomcat服务 6 重启nginx服务 7 浏览器访问nginx,我的是这个地址:http://192.168.154.129:8044/index.jsp,每次刷新,都会在两个tomcat之间
