Web服务（07）——LNMP一键部署

Web服务（07）——LNMP一键部署

前言

之前的博客中有介绍过LAMP的架构，而LNMP和LAMP的区别就在于使用Nginx而不是Apache。

一、LNMP架构介绍

LNMP是Linux+Nginx+Mysql+PHP的组合方式，其特点是利用Nginx的快速与轻量级，替代以前的LAMP的方式，由于安装方便，并且安装脚本也随时更新。

LNMP的优点在于：占用VPS资源较少，Nginx配置起来也比较简单方便，利用fast-cgi的方式动态解析PHP脚本。

LNMP的缺点也同样很明显：php-fpm组件的负载能力优先，在访问量巨大的时候，php-fpm进程容易僵死，容易发生502bad gateway的错误。

二、LNMP部署脚本

#一键部署LNMP脚本
#将mysql，nginx，php，boost安装包拖入虚拟机内
#!/bin/bash
#准备软件包
read -p "请输入安装包所在目录如/opt：" mulu
#关闭核心防护和防火墙
systemctl stop firewalld
setenforce 0
#安装依赖包
yum -y install pcre-devel \
zlib-devel \
gcc \
gcc-c++ \
make \
ncurses \
ncurses-devel \
bison \
cmake \
gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel
