LNMP原理及源码安装LNMP、搭建论坛的shell脚本

## 一、LNMP ##

1、LNMP组成：

①Nginx服务：一款高性能的轻量级Web服务软件

》》》稳定性高

》》》支持正则，系统资源消耗低

》》》对HTTP并发连续的处理能力高（理论上处理3~5万个并发请求，实际上大概2~3万个并发请求）

②MySQL服务

③PHP服务

## 二、LNMP框架 ##

## 三、LNMP业务层面的对接原理 ##

### 1、LNMP的组成 ###

由Nginx 、PHP 、MysQL组成

三者关系：各司其职,对接集成

①各司其职：云计算/运维角度分析

Nginx 属于前端 主要提供静态处理+跳转到php的功能

PHP 属于后端 只要处理动态任务，和对接数据库

MysQL存储存储数据(存储基础数据、核心数据、业务数据)

### 2、对接集成(组合） ###

nginx------>> 对接PHP-------->>对接Mysql

### 3、对接方式 ###

#### 3.1Nginx <=========> php ####

3.1.1 Nginx角度来看，Nginx只要修改配置文件即可修改:

①location ~ l.php$s \{ \}

②在以上模块中修改php-fpm模块的位置:127.0.0.1:9000

《FPM是Nginx对接PHP的一个小工具(接口)，此接口会调用FastCgi这个API接口，从而和PHP进行对接》

3.1.2、从PHP角度来看，PHP需要开启Pid进程暴露9000端口，用于方便Nginx来对接。

**小结**:Nginx和php直接对接交互，就是通过ip: port来交互的

#### 3.2 php<=========>mysql ####

3.2.1 从PHP角度来看

①需要在./configure配置过程中，指向mysql.sock 文件的位置

②php.ini调整"mysqli.default socket= /usr/local/mysql/mysql.sock”配置参数来和mysql进行对接从

（mysql.sock是用于将访问请求或调用等来访任务传递到mysql服务内部的一个通讯文件，mysql是由自己的内部空间的，而通讯就依靠mysql.sock）

3.2.1 MySQL角度来看

①本身如果PHP使用的是root权限来访问的话，则无需操作

②如果PHP借助于独立用户来访问的话，则需要进行grant提权处理

## 四、一键部署LNMP服务 ##

### **1、安装过程收集的log需要的可自行下载** ###

**百度链接：https://pan.baidu.com/s/1HEdUoLx6Z3dQkQs9ZcUSXA?pwd=lnmp  
提取码：lnmp**

（文件过大，不便贴图）

### 2、LNMP的shell内容 ###

脚本运行完以后需要执行下，source /etc/profile。当时只是在shell脚本的环境加载生效，退出脚本后需要重新加载一下。
