Haproxy实现负载均衡

1.  环境规划：

2.  Haproxy主配置文件：

[root@node1 ~]# vim /etc/haproxy/haproxy.cfg
 
global  ##全局配置
  log         127.0.0.1 local2
  chroot      /usr/local/haproxy
  pidfile     /var/run/haproxy.pid
  maxconn     4000
  user        haproxy
  group       haproxy
  daemon
  stats socket /usr/local/haproxy/stats
 
defaults  ##默认配置
    mode                    http
    log                     global
    option                  httplog
    option                  dontlognull
    option http-server-close
    option forwardfor       except 127.0.0.0/
