Haproxy实现动静分离和Discuz论坛部署

1.实验拓扑:


2.后端部署Httpd服务器和Mysql服务器 1.安装程序
分别在lab2,lab3,lab4上安装httpd,
在lab3,lab4上安装php以及php-mysql
2.部署论坛
#在Mysql服务器上创建一个Discuz数据库

mysql> create database discuz;

#为Mysql提供远程访问帐号,并配置密码

mysql> grant all on discuz.* to bbs@'172.16.21.%' identified by '123456';

#将论坛程序解压到lab3的网站根目录,通过网页访问lab3,安装论坛程序



论坛程序已经可以访问



将网站根目录复制到lab4及lab2的对应目录下,并保证文件权限

[root@lab4 ~]# scp -r lab3:/var/www/html/* /var/www/html/
[root@lab4 ~]# scp -r lab2:/var/www/html/* /var/www/html/

3.创建配置共享存储

[root@lab2 html]# cat /etc/exports
/var/www/html/data 172.16.21.0/24(rw,all_squash,anonuid=48,insecure)
#lab3挂载
[root@lab4 data]# mount lab2:/var/www/html/data/ /var/www/html/data/
#lab4挂载
[root@lab4 data]# mount lab2:/var/www/html/data/ /var/www/html/data/

3.前端Haproxy配置#Haproxy配置文件

[root@lab1 ~]# cat /etc/haproxy/haproxy.cfg

启动Haproxy,访问论坛
发帖,图片上传测试



#帖子图片访问正常



#清除Cookie后访问成功



#Httpd配置调整
将日志格式中需要记录访问IP的%h更改为{X-Forwarded-For}i,以方便记录统计数据
