系统运维
什么是LNMP架构
LNMP平台就是Linux、Ngnix、 mysql、 PHP的组合架构，需要Linux服务器、Mysql数据库、PHP解析环境
MYSQL安装配置
为了与Nginx、PHP环境保持一致，此处选择采用源代码编译的方式安装MySQL组件
MySQL部署的方法
编译安装MySQL
优化调整
初始化数据库
启动mysq|服务并设置root数据库账号的密码
PHP解析环境的安装
配置网页动静分离，解析PHP,有两种方法可以选择
使用PHP的FPM模块
将访问PHP页面的Web请求转交给Apache服务器去处理
较新版本的PHP已经自带FPM模块，用来对PHP解析实例进行管理、优化解析效率
FastCGI将Http Server和动态脚本语言分离开
Nginx专门处理静态请求，转发动态请求
PHP_FPM专门 ]解析PHP动态请求
单服务器的LNMP架构通常使用FPM的方式来解析PHP，本次也使用FPM模块处理动态请求。
PHP编译安装步骤
编译安装PHP
编译选项时添加"–enable-fpm” 以启用此模块
安装后的调整，主要是配置文件的建立与相应命令工具的路径优化
安装ZendGuardloader (提高PHP解析效率)，并进行加载配置
实验准备
1.将宿主机上的工具包共享出去
2.通过Samba服务将工具包挂载到Linux系统
[root@localhost ~]# mkdir /mnt/tools
[root@localhost ~]# smbclient -L //192.168.100.50/
Enter SAMBA\\\\root\\\'s
