LNMP简介
LNMP代表的就是：Linux系统下Nginx+MySQL+PHP这种网站服务器架构。
作为 Web 服务器：相比 Apache，Nginx 使用更少的资源，支持更多的并发连接，体现更高的效率。
目前大部分的互联网公司因为历史原因，使用的架构大多是比较旧的版本，但这不影响公司业务的开展。技术是一种工具，不管这种工具的新旧损耗，只要能够使大局稳定运行，即是值得学习的！
本文采用Nginx 1.12、MySQL 5.5、PHP 5.3进行搭建。
预装环境
$ yum -y install gcc gcc-c++
$ yum -y install autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

安装mysql5.5
$ groupadd mysql
$ useradd -g mysql mysql
$ cd /usr/local/software
$ tar -zxvf mysql-5.5.3-m3.tar.gz
$ cd mysql-5.5.3-m3/
$ ./configure --prefix=/usr/local/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
$ make && make install
配置mysql5.5
$ chmod +w /usr/local/mysql
$ chown -R mysql:mysql /usr/local/mysql
$ mkdir -p /db/mysql/data/
$ mkdir -p /db/mysql/data/binlog/
$ mkdir -p /db/mysql/data/relaylog/
$ chown -R mysql:mysql /db/mysql/

extension = "memcache.so"

extension = scws.so
scws.default.charset = gbk
scws.default.fpath = /usr/local/scws/etc
修改php配置文件
查找output_buffering = Off
修改为output_buffering = On
再查找; cgi.fix_pathinfo=1
修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。
