环境： 服务器操作系统：centos7.3 * haproxy： 外网IP: 10.2.13.220/24 内网IP：192.168.20.131/24 * WEB server: node7.51yuki.cn: 外网IP：10.2.13.219/24 内网IP：192.168.20.132/24 node8.51yuki.cn： 外网IP：10.2.13.217/24 内网IP：192.168.20.133/24 * Database Server master_mysql.51yuki.cn： 内网IP：192.168.20.135/24 第一步：分别在node7.51yuki.cn和node8.51yuki.cn的机器上安装nginx和php 版本： nginx： nginx-1.12.2 php： php-5.6.33 安装脚本： https://gitee.com/louis1986/shell_scripts/blob/master/Software_Install/install_lnmp_centos7.sh 把nginx和php-fpm添加到开机自动启动 [root@node8 ~]# chkconfig --add php-fpm [root@node8 ~]# echo “/usr/local/nginx-1.12.2/sbin/nginx ">>/etc/rc.local 第二步：在master_mysql.51yuki.cn机器上安装mysql服务 版本：mysql-5.6.38（安装mysql二进制包） 查看博客地址 http://www.cnblogs.com/51yuki/p/mysql01.html 第三步：登录mysql，创建数据库 mysql> create database discuz; Query OK, 1 row affected (0.01 sec) mysql> grant all on discuz.* to discuz@'192.168.20.%' identified by 'discuz&0611'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) 第四步：在2台web服务器上安装discuz（以node8.51yuki.cn为例） 1）网站目录 [root@node7 ~]# mkdir -p /opt/web/discuz 下载软件，然后解压，把upload目录里的所有文件拷贝到/opt/web/discuz [root@node8 ~]# cd /usr/local/src/ [root@node8 src]# wget http://download.comsenz.com/DiscuzX/3.1/Discuz_X3.1_SC_UTF8.zip [root@node8 src]# unzip Discuz_X3.1_SC_UTF8.zip [root@node8 src]# cp -r upload/* /opt/web/discuz/ 2）配置虚拟主机 [root@node8 discuz]# cd /usr/local/nginx-1.12.2/conf/ [root@node8 conf]# mkdir conf.d [root@node8 conf.d]# vim ../nginx.conf 增加如下 include conf.d/*.conf； 配置虚拟主机 [root@node8 conf.d]# vim discuz.conf server { listen 8080; server_name localhost; location / { root /opt/web/discuz; index index.php index.html index.htm; } location ~ \.php$ { root /opt/web/discuz; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } 3）改变文件及目录权限 [root@node8 discuz]# chmod -R 777 ./config/ ./data/ ./uc_client/ ./uc_server/ 4）安装 http://10.2.13.217:8080/install/ 最后，更改两台服务器的监听地址，让其监听内网的ip地址 listen 192.168.20.133:8080; [root@node8 conf.d]# /usr/local/nginx-1.12.2/sbin/nginx -s stop [root@node8 conf.d]# /usr/local/nginx-1.12.2/sbin/nginx [root@node8 conf.d]# ss -tunlp|grep 8080 tcp LISTEN 0 128 192.168.20.133:8080 *:* users:(("nginx",pid=1339,fd=7),("nginx",pid=1338,fd=7)) 最后node7.51yuki.cn机器上操作方式类似 第五步：配置haproxy 1）先安装haproxy [root@proxy01 ~]# yum -y install haproxy 2）配置haproxy.cfg ~~~ [root@proxy01 haproxy]# cat haproxy.cfg #--------------------------------------------------------------------- # Example configuration for a possible web application.
