一、在cs2、cs3、cs4上安装httpd

[root@cs2 ~]# yum install httpd

[root@cs3 ~]# yum install httpd

[root@cs4 ~]# yum install httpd

二、在cs3、cs4上安装php和php-mysql

[root@cs3 ~]# yum install php[root@cs3 ~]# yum install php-mysql

[root@cs4 ~]# yum install php[root@cs4 ~]# yum install php-mysql

三、在cs5上安装mysql

[root@cs5 ~]# yum install mariadb-server

四、在cs5上给dz论坛创建数据库

[root@cs5 ~]# systemctl start mariadb[root@cs5 ~]# mysql#创建一个discuz用的数据库，库名叫dzMariaDB [(none)]> create database dz;#创建并授权账号dzadmin密码123321给dz库，授权范围为全网MariaDB [(none)]> grant all privileges on dz.* to dzadmin@'%' identified by '123321';#授权账号dzadmin密码123321给dz库，授权范围为本地MariaDB [(none)]> grant all privileges on dz.* to dzadmin@localhost identified by '123321';#刷新权限MariaDB [(none)]> flush privileges;

五、配置cs2、cs3、cs4的httpd

[root@cs2 ~]# vim /etc/httpd/conf/httpd.confServerName cs2.xinfeng.com:80    #修改此处DocumentRoot "/var/www/html/upload"    #因为次文件还不存在，所以会报错，等装了dz之后再执行之后的就OK了[root@cs2 ~]# httpd -t[root@cs2 ~]# systemctl start httpd

[root@cs3 ~]# vim /etc/httpd/conf/httpd.confServerName cs3.xinfeng.com:80    #修改此处DocumentRoot "/var/www/html/upload"    [root@cs3 ~]# httpd -t[root@cs3 ~]# systemctl start httpd

[root@cs4 ~]# vim /etc/httpd/conf/httpd.confServerName cs4.xinfeng.com:80    #修改此处DocumentRoot "/var/www/html/upload"[root@cs4 ~]# httpd -t[root@cs4 ~]# systemctl start httpd

六、在cs3安装discuz

[root@cs3 ~]# wget  http://download.comsenz.com/DiscuzX/3.2/Discuz_X3.2_SC_UTF8.zip[root@cs3 ~]# mkdir Discuz[root@cs3 ~]# unzip -d /root/Discuz Discuz_X3.2_SC_UTF8.zip[root@cs3 ~]# cp -a /root/Discuz/* /var/www/html/[root@cs3 ~]# chmod -R 777 /var/www/html/upload/*

打开cs3.xinfeng.com安装

论坛管理员账号admin，密码123

七、将cs3上安装完成后的网站根目录复制到cs2和cs4上

#复制cs3下的/var/www/html所有文件到cs2/var/www/html/下[root@cs3 ~]# scp -r /var/www/html/* 192.168.1.114:/var/www/html/

#复制cs3下的/var/www/html所有文件到cs4/var/www/html/下[root@cs3 ~]# scp -r /var/www/html/* 192.168.1.115:/var/www/html/

八、将cs3和cs4的静态文件存放目录挂载到cs2下

#/var/www/html/upload中需要挂载的目录如下data ┄┄┄数据缓存及附件static ┄┄┄静态文件

设置cs2为NFS服务器

[root@cs2 ~]# yum install nfs-utils[root@cs2 ~]# yum install rpcbind[root@cs2 ~]# service rpcbind start[root@cs2 ~]# vim /etc/exports#NFS输出目录为data，可以访问这个目录的主机为cs3和cs4，权限为读写，访问uid为0(root)，允许超过1024的端口号连接/var/www/html/upload/data/ 192.168.1.113(rw,all_squash,anonuid=0,insecure)/var/www/html/upload/data/ 192.168.1.115(rw,all_squash,anonuid=0,insecure)#NFS输出目录为static，可以访问这个目录的主机为cs3和cs4，权限为读写，访问uid为0(root)，允许超过1024的端口号连接/var/www/html/upload/static/ 192.168.1.113(rw,all_squash,anonuid=0,insecure)/var/www/html/upload/static/ 192.168.1.115(rw,all_squash,anonuid=0,insecure)[root@cs2 ~]# service nfs start#查看共享状态[root@cs2 ~]# showmount -eExport list for cs2.xinfeng.com:/var/www/html/upload/static 192.168.1.115,192.168.1.113/var/www/html/upload/data   192.168.1.115,192.168.1.113

在cs3上挂载

[root@cs3 ~]# yum install nfs-utils[root@cs3 ~]# yum install rpcbind[root@cs3 ~]# service rpcbind start[root@cs3 ~]# service nfs start[root@cs3 ~]# mount 192.168.1.114:/var/www/html/upload/data/ /var/www/html/upload/data/[root@cs3 ~]# mount 192.168.1.114:/var/www/html/upload/static/ /var/www/html/upload/static/[root@cs3 ~]# showmount -e 192.168.1.114Export list for 192.168.1.114:/var/www/html/upload/static 192.168.1.115,192.168.1.113/var/www/html/upload/data   192.168.1.115,192.168.1.113

在cs4上挂载

[root@cs4 ~]# yum install nfs-utils[root@cs4 ~]# yum install rpcbind[root@cs4 ~]# service rpcbind start[root@cs4 ~]# service nfs start[root@cs4 ~]# mount 192.168.1.114:/var/www/html/upload/data/ /var/www/html/upload/data/[root@cs4 ~]# mount 192.168.1.114:/var/www/html/upload/static/ /var/www/html/upload/static/[root@cs4 ~]# showmount -e 192.168.1.114Export list for 192.168.1.114:/var/www/html/upload/static 192.168.1.115,192.168.1.113/var/www/html/upload/data   192.168.1.115,192.168.1.113

九、在cs1上安装配置haproxy

开起日志功能

[root@cs1 ~]# vim /etc/rsyslog.conf#打开或增加一下几行，让udp514端口处于监听状态，并将日志纪录到指定文件中$ModLoad imudp$UDPServerRun 514local2.*                                                /var/log/haproxy.log[root@cs1 ~]# systemctl restart rsyslog.service[root@cs1 ~]# ss -unl | grep 514UNCONN     0      0            *:514                      *:*                  UNCONN     0      0           :::514                     :::*

配置haproxy

[root@cs1 ~]# yum install haproxy[root@cs1 ~]# vim /etc/haproxy/haproxy.cfg#---------------------------------------------------------------------global    #全局配置

    log         127.0.0.1 local2    #日志纪录位置

    chroot      /var/lib/haproxy    #haproxy的工作目录    pidfile     /var/run/haproxy.pid    #pid文件位置    maxconn     4000                    #最大连接数    user        haproxy                #运行时使用的用户身份    group       haproxy                #运行时使用的组身份    daemon                            #启动为守护进程，不加此处运行在前台

    stats socket /var/lib/haproxy/stats    #本地访问stats统计信息时以套接字方式通信

defaults    #默认配置    mode                    http    #已http模式运行    log                     global    #默认日志为全局配置中日志的设置    option                  httplog    option                  dontlognull    option http-server-close    option forwardfor       except 127.0.0.0/8    #除本机外所有发往服务器的请求首部中加入“X-Forwarded-For”首部    option                  redispatch    retries                 3    timeout http-request    10s    timeout queue           1m    timeout connect         10s    timeout client          1m    timeout server          1m    timeout http-keep-alive 10s    timeout check           10s    maxconn                 3000    #前端最大并发连接数

listen static    #设置统计报告页面    bind *:9000    #监听在本机9000端口    stats enable    #打开    stats hide-version    #隐藏haproxy版本    stats uri /hadzadmin?stats    #统计页面路径    stats realm "HAProxy/ Static"    #打开统计页面的认证功能    stats auth hasts:123            #进入统计页面所使用的账号hasts和密码123    stats admin if TRUE            #条件满足时进入管理级别

frontend  dz    #前端设置    bind *:80    #监听在80端口    acl url_static path_beg -i /data /static /images /javascript /stylesheets    #url开头为这些的静态内容    acl url_static path_end -i .jpg .gif .png .css .js .html .ico    #url结尾带为这些的静态内容    use_backend staser  if url_static    #如果静态内容符合url_static的条件，就调度到staser中的服务器    default_backend             dyser    #其他默认调度到dyser中的服务器

backend dyser    #后端动态内容服务器设置    cookie srv insert nocache    #在cookie中插入srv字串防止登录信息丢失    balance     roundrobin    #调度算法为轮询    server      cs3 192.168.1.113:80 check    server      cs4 192.168.1.115:80 check

backend staser    #后端静态内容服务器设置    balance     roundrobin    server  cs1 192.168.1.114:80 check

[root@cs1 ~]# systemctl start haproxy

修改cs2、cs3、cs4的http配置文件，让他们能收到真实访问的ip

[root@cs2 ~]# vim /etc/httpd/conf/httpd.conf#修改一下内容    LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined[root@cs2 ~]# service httpd reload#cs3和cs4执行同样的操作

十、测试

分别看下cs2,cs3,cs4最近的访问日志

[root@cs2 ~]# tail -1 /var/log/httpd/access_log 192.168.1.110 - - [05/Jun/2016:16:36:12 +0800] "GET /data/attachment/forum/201606/05/161843j4au463pthh432zf.png HTTP/1.1" 304 - "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.122 Safari/537.36 SE 2.X MetaSr 1.0"[root@cs3 uc_server]# tail -1 /var/log/httpd/access_log 192.168.1.110 - - [05/Jun/2016:16:33:07 +0800] "GET /misc.php?mod=patch&action=ipnotice&_r=0.40765136777967004&inajax=1&ajaxtarget=ip_notice HTTP/1.1" 200 65 "http://cs1.xinfeng.com/forum.php?mod=viewthread&tid=1&extra=page%3D1" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36[root@cs4 data]# tail -1 /var/log/httpd/access_log 192.168.1.110 - - [05/Jun/2016:16:33:07 +0800] "GET /misc.php?mod=patch&action=pluginnotice&inajax=1&ajaxtarget=plugin_notice HTTP/1.1" 200 65 "http://cs1.xinfeng.com/forum.php?mod=viewthread&tid=1&extra=page%3D1" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36"
