一所要软件 (1)
二安装软件 (1)
1 安装keepalive (1)
2配置keepalived (1)
3 安装haproxy (3)
三 haproxy配置 (3)
3 安装haproxy
Tar zxcvf haproxy-1.4.15.tar.gz
make TARGET=linux26 PREFIX=/home/admin/haproxy
make install PREFIX=/home/admin/haproxy
TARGET=linux26为内核版本，根据系统参数安装用 uname –r 查看内核版本
Mkdir /home/admin/haproxy/conf
Mkdir /home/admin/haproxy/logs
三 haproxy配置
Master salve 相同配置

listen stats_auth 192.168.0.148:80 从服务器填写自己的ip
stats enable
stats uri /admin-status
stats auth feiyang:feiyang
stats admin if TRUE
其他的配置没变化。
Iptables设置在主从服务器执行 iptables –I INPUT –d 224.0.0.18 –j ACCEPT
支持 vrrp通信。否则主从keepalived无法切换
