一、在cs2、cs3、cs4上安裝httpd
[root@cs2 ~]# yum install httpd [root@cs3 ~]# yum install httpd [root@cs4 ~]# yum install httpd
二、在cs3、cs4上安裝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上安裝mysql
[root@cs5 ~]# yum install mariadb-server
四、在cs5上給dz論壇創建數據庫
[root@cs5 ~]# systemctl start mariadb [root@cs5 ~]# mysql #創建一個discuz用的數據庫，庫名叫dz MariaDB [(none)]> create database dz; #創建並授權賬號dzadmin密碼123321給dz庫，授權範圍爲全網 MariaDB [(none)]> grant all privileges on dz.* to dzadmin@'%' identified by '123321'; #授權賬號dzadmin密碼123321給dz庫，授權範圍爲本地 MariaDB [(none)]> grant all privileges on dz.* to dzadmin@localhost identified by '123321'; #刷新權限 MariaDB [(none)]> flush privileges;
五、配置cs2、cs3、cs4的httpd
[root@cs2 ~]# vim /etc/httpd/conf/httpd.conf ServerName cs2.xinfeng.com:80 #修改此處 DocumentRoot "/var/×××w/html/upload" #因爲次文件還不存在，所以會報錯，等裝了dz之後再執行之後的就OK了 [root@cs2 ~]# httpd -t [root@cs2 ~]# systemctl start httpd [root@cs3 ~]# vim /etc/httpd/conf/httpd.conf ServerName cs3.xinfeng.com:80 #修改此處 DocumentRoot "/var/×××w/html/upload" [root@cs3 ~]# httpd -t [root@cs3 ~]# systemctl start httpd [root@cs4 ~]# vim /etc/httpd/conf/httpd.conf ServerName cs4.xinfeng.com:80 #修改此處 DocumentRoot "/var/×××w/html/upload" [root@cs4 ~]# httpd -t [root@cs4 ~]# systemctl start httpd
六、在cs3安裝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/×××w/html/ [root@cs3 ~]# chmod -R 777 /var/×××w/html/upload/*
打開cs3.xinfeng.com安裝
論壇管理員賬號admin，密碼123
七、將cs3上安裝完成後的網站根目錄複製到cs2和cs4上
#複製cs3下的/var/×××w/html所有文件到cs2/var/×××w/html/下 [root@cs3 ~]# scp -r /var/×××w/html/* 192.168.1.114:/var/×××w/html/ #複製cs3下的/var/×××w/html所有文件到cs4/var/×××w/html/下 [root@cs3 ~]# scp -r /var/×××w/html/* 192.168.1.115:/var/×××w/html/
八、將cs3和cs4的靜態文件存放目錄掛載到cs2下
#/var/×××w/html/upload中需要掛載的目錄如下 data ┄┄┄數據緩存及附件 static ┄┄┄靜態文件
設置cs2爲NFS服務器
[root@cs2 ~]# yum install nfs-utils [root@cs2 ~]# yum install rpcbind [root@cs2 ~]# service rpcbind start [root@cs2 ~]# vim /etc/exports #NFS輸出目錄爲data，可以訪問這個目錄的主機爲cs3和cs4，權限爲讀寫，訪問uid爲0(root)，允許超過1024的端口號連接 /var/×××w/html/upload/data/ 192.168.1.113(rw,all_squash,anonuid=0,insecure) /var/×××w/html/upload/data/ 192.168.1.115(rw,all_squash,anonuid=0,insecure) #NFS輸出目錄爲static，可以訪問這個目錄的主機爲cs3和cs4，權限爲讀寫，訪問uid爲0(root)，允許超過1024的端口號連接 /var/×××w/html/upload/static/ 192.168.1.113(rw,all_squash,anonuid=0,insecure) /var/×××w/html/upload/static/ 192.168.1.115(rw,all_squash,anonuid=0,insecure) [root@cs2 ~]# service nfs start #查看共享狀態 [root@cs2 ~]# showmount -e Export list for cs2.xinfeng.com: /var/×××w/html/upload/static 192.168.1.115,192.168.1.113 /var/×××w/html/upload/data 192.168.1.115,192.168.1.113
在cs3上掛載
[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/×××w/html/upload/data/ /var/×××w/html/upload/data/ [root@cs3 ~]# mount 192.168.1.114:/var/×××w/html/upload/static/ /var/×××w/html/upload/static/ [root@cs3 ~]# showmount -e 192.168.1.114 Export list for 192.168.1.114: /var/×××w/html/upload/static 192.168.1.115,192.168.1.113 /var/×××w/html/upload/data 192.168.1.115,192.168.1.113
在cs4上掛載
[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/×××w/html/upload/data/ /var/×××w/html/upload/data/ [root@cs4 ~]# mount 192.168.1.114:/var/×××w/html/upload/static/ /var/×××w/html/upload/static/ [root@cs4 ~]# showmount -e 192.168.1.114 Export list for 192.168.1.114: /var/×××w/html/upload/static 192.168.1.115,192.168.1.113 /var/×××w/html/upload/data 192.168.1.115,192.168.1.113
九、在cs1上安裝配置haproxy
開起日誌功能
[root@cs1 ~]# vim /etc/rsyslog.conf #打開或增加一下幾行，讓udp514端口處於監聽狀態，並將日誌紀錄到指定文件中 $ModLoad imudp $UDPServerRun 514 local2.* /var/log/haproxy.log [root@cs1 ~]# systemctl restart rsyslog.service [root@cs1 ~]# ss -unl | grep 514 UNCONN 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 #日誌紀錄位置 chroot /var/lib/haproxy #haproxy的工作目錄 pidfile /var/run/haproxy.pid #pid文件位置 maxconn 4000 #最大連接數 user haproxy #運行時使用的用戶身份 group haproxy #運行時使用的組身份 daemon #啓動爲守護進程，不加此處運行在前臺 stats socket /var/lib/haproxy/stats #本地訪問stats統計信息時以套接字方式通信 defaults #默認配置 mode http #已http模式運行 log global #默認日誌爲全局配置中日誌的設置 option httplog option dontlognull option http-server-close option forwardfor except 127.0.0.0/8 #除本機外所有發往服務器的請求首部中加入“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 #前端最大併發連接數 listen static #設置統計報告頁面 bind *:9000 #監聽在本機9000端口 stats enable #打開 stats hide-version #隱藏haproxy版本 stats uri /hadzadmin?stats #統計頁面路徑 stats realm "HAProxy/ Static" #打開統計頁面的認證功能 stats auth hasts:123 #進入統計頁面所使用的賬號hasts和密碼123 stats admin if TRUE #條件滿足時進入管理級別 frontend dz #前端設置 bind *:80 #監聽在80端口 acl url_static path_beg -i /data /static /images /javascript /stylesheets #url開頭爲這些的靜態內容 acl url_static path_end -i .jpg .gif .png .css .js .html .ico #url結尾帶爲這些的靜態內容 use_backend staser if url_static #如果靜態內容符合url_static的條件，就調度到staser中的服務器 default_backend dyser #其他默認調度到dyser中的服務器 backend dyser #後端動態內容服務器設置 cookie srv insert nocache #在cookie中插入srv字串防止登錄信息丟失 balance roundrobin #調度算法爲輪詢 server cs3 192.168.1.113:80 check server cs4 192.168.1.115:80 check backend staser #後端靜態內容服務器設置 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，讓他們能收到真實訪問的ip
[root@cs2 ~]# vim /etc/httpd/conf/httpd.conf
#修改一下內容
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執行同樣的操作十、測試
分別看下cs2,cs3,cs4最近的訪問日誌
[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"
