LNMP架构——利用lnmp搭建可用Discuz论坛

本次实验是在[LNMP架构——php+nginx+mysql源码编译搭建lnmp环境][LNMP_php_nginx_mysql_lnmp]基础上进行的，lnmp架构已经搭建好，接下来我将以搭建论坛并且客户使用论坛为例，演示整个过程。

     *  二、搭建Discuz论坛
     *   *   *  实验环境
             *  实验

## 一、前言 ##

**lnmp架构的整个访问过程如下：**

用户从前端页面开始访问
    先到达nginx，由nginx判断是静态资源还是动态页面请求
    如果是静态资源，nginx直接给客户
    如果是动态页面，nginx会通过fastcgi去找php，牵扯到数据的话还会与mysql交互

**两个服务之间的关系是通过套节字关联起来的：**

用户通过访问php（套节字文件）动态页面向nginx（套节字文件）服务器发送请求
    nginx服务器发现是动态资源，就会去加载数据库，然后向后台的数据库写入数据

## 二、搭建Discuz论坛 ##

#### 实验 ####

在server1虚拟机上：  
步骤一：在网上下载Discuz安装包  
![在这里插入图片描述][20200217113511261.png]  
步骤二：下载解压工具

yum install unzip -y

![在这里插入图片描述][20200217113525946.png]  
步骤三：解压压缩包

直接解压在nginx的发布目录下，按照部署说明配置好之后，在浏览器就可以搜索到Discuz界面，开始搭建论坛

unzip Discuz_X3.2_SC_UTF8.zip -d /usr/local/lnmp/nginx/html/

步骤四：进入指定解压后的目录，查看说明文档

cd /usr/local/lnmp/nginx/html/

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0NhcGVqYXNtaW5lWQ_size_16_color_FFFFFF_t_70 1]  
步骤五：开启nginx，php-fpm服务

nginx 
    ps aux | grep nginx
    /etc/init.d/php-fpm start
    netstat -antuple

在真机上测试：  
进入浏览器，搜索http://172.25.1.101/upload，开始部署论坛

解决：提示给文件权限

cd /usr/local/lnmp/nginx/html/upload/
    chmod 777 config -R
    chmod 777 data -R
    chmod 777 uc_* -R

上述报错解决：需要修改配置文件

vim /usr/local/lnmp/php/etc/php.ini   #修改配置文件，添加如下内容
    1013 pdo_mysql.default_socket= /usr/local/lnmp/mysql/data/mysql.sock
    1162 mysql.default_socket = /usr/local/lnmp/mysql/data/mysql.sock
    1221 mysqli.default_socket = /usr/local/lnmp/mysql/data/mysql.sock
    
    /etc/init.d/php-fpm reload  #重新加载php

上述报错，是因为nginx用户 对于 /usr/local/lnmp/mysql/data 目录没有权限，更改目录权限为：755

可以看出，客户端注册的用户信息通过nginx和php将数据写入了mysql数据库当中。
