haproxy高可用以及双主模式(二)
haproxy主备虚拟VIP：192.168.33.130
把haproxy-01的配置文件拷贝到haproxy-02机器相应的目录即可
root@haproxy-01 haproxy]# scp haproxy.cfg root@192.168.33.132:/etc/haproxy/
haproxy.cfg 100% 3520 3.4KB/s 00:00启动haproxy-02服务
# /etc/init.d/haproxy restart
Stopping haproxy:
Starting haproxy: 关于haproxy-02日志记录和haproxy-01记录方式一样

安装keepalived
在haproxy机器上分别安装keepalived
# yum install keepalived -y
# yum install keepalived -yhaproxy-01机器上keepalived配置文件内容如下
# cat /etc/keepalived/keepalived.conf
global_defs {
notification_email {

分别在haproxy-01/02机器启动keepalived服务
# /etc/init.d/keepalived start

通过访问得知，虚拟vip访问正常。轮询访问
模拟故障把haproxy-01机上的haproxy和keepalived服务停止
# /etc/init.d/haproxy stop
Stopping haproxy:
# /etc/init.d/keepalived stop
Stopping keepalived: 在haproxy-02机器上查看虚拟VIP情况
# ip a|grep 130
