1、实验拓扑
2、后端 HTTP 主机配置
2.1 HTTP 主机的安装及 conf 文件配置
[root@Tang-1 ~]# ipinfo
enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.16.141.209 netmask 255.255.255.0 broadcast 172.16.141.255
[root@Tang-1 ~]# rpm -q httpd # 安装 HTTPD
httpd-2.4.6-90.el7.centos.x86_64
[root@Tang-1 ~]# cat /etc/httpd/conf.d/mylisten.conf # 虚拟主机的配置
Listen 8080
<VirtualHost 172.16.141.209:8080> # 虚拟主机 1 的配置

</virtualHost>
Listen 80
<VirtualHost 172.16.141.209:80> # 虚拟主机 2 的配置

DocumentRoot "/data/web/tang"
<Directory "/data/web/tang">

</Directory>
</virtualHost>2.2 HTTP 虚拟主机的默认网页配置
[root@Tang-1 ~]# cat /data/web/neo/index.html
<h1>This is neo's website!</h1>
[root@Tang-1 ~]# cat /data/web/tang/index.html
<h1>This is tang's website!</h1>2.3 HTTP 虚拟主机的服务启动及网页测试
[root@Tang-1 ~]# systemctl start httpd # 启动服务
[root@Tang-1 ~]# ss -tnl # 查看端口号是否正常启动

[root@Tang haproxy]# curl http://172.16.141.209:8080 # 访问虚拟主机的默认网页
<h1>This is neo's website!</h1>3、HAProxy 主机配置（代理配置）
3.1 HAProxy 主机的 haproxy.cfg 文件配置
[root@Tang ~]# ipinfo
enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.16.141.252 netmask 255.255.255.0 broadcast 172.16.141.255

[root@Tang haproxy]# systemctl start haproxy

LISTEN 0 128 :::22 :::*4、HAProxy 主机配置（log 配置）
4.1 HAProxy 主机的 haproxy.cfg 文件查看
[root@Tang haproxy]# vim /etc/haproxy/haproxy.cfg
global
# 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
#
log 127.0.0.1 local24.2 HAProxy 主机的 Rsyslog 程序的文件配置
[root@Tang ~]# vim /etc/rsyslog.conf
local2.* /var/log/haproxy/haproxy.log
# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514
# Provides TCP syslog reception
$ModLoad imtcp
$InputTCPServerRun 5144.3 HAProxy 主机的 Rsyslog 的服务重启
[root@Tang ~]# systemctl start rsyslog # 启动 Rsyslog
[root@Tang ~]# ss -tnl # 查看 514 端口号是否成功监听
