实验
iP 规划
Haproxy 172.16.31.30
静态服务器 172.16.31.31
动态服务器 172.16.31.32
1 安装Haproxy并且启动配置文件选项
# yum install haproxy -y
#vi /etc/rsyslog.conf
启用一下两行
$ModLoad imudp
$UDPServerRun 514
添加以下一行
local2.* /var/log/haproxy.log

# to have these messages end up in /var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network log events. This is done
# by adding the ‘-r‘ option to the SYSLOGD_OPTIONS in
# /etc/sysconfig/syslog
#
# 2) configure local2 events to go to the /var/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/log/haproxy.log
#

3准备静态和动态页面
在31主机上准备静态页面
# vi /var/www/html/index.html
hello
在32主机上准备动态页面
# vi index.php
<?php
phpinfo();
?>
