1、三个节点安装haproxy，并设置开机自动启动

# yum install -y haproxy
# systemctl enable haproxy

2、跟rsyslog结合配置haproxy日志，在三个节点上都操作
配置/etc/rsyslog.d/haproxy.conf

$ModLoad imudp
$UDPServerRun 514
$template Haproxy,"%rawmsg% \n"
local0.=info -/var/log/haproxy.log;Haproxy
local.notice -/var/log/haproxy-status.log;Haproxy
local.* ~
# systemctl restart rsyslog.service
# systemctl status rsyslog.service

3、在三个节点上配置haproxy.cfg文件

global
log             127.0.0.1 local3
    chroot          /var/lib/haproxy
    pidfile         /var/run/haproxy.pid

4、修改三个节点的内核参数使haproxy正常启动

# echo "net.ipv4.ip_nonlocal_bind = 1" >>/etc/sysctl.conf
# echo "net.ipv4.ip_forward = 1" >>/etc/sysctl.conf
# sysctl -p

5、三个节点启动haproxy服务

# systemctl restart haproxy
# systemctl status haproxy

6、访问haproxy前端web界面
