和LAMP不同的是，LNMP中的N指的是Nginx（类似于Apache的一种web服务软件），并且php是作为一个独立服务存在的，这个服务叫做php-fpm，Nginx直接处理静态请求，动态请求会转发给php-fpm。
目前LNMP环境的应用非常多。在静态页面的处理上，Nginx比Apache更强；但在动态页面的处理上，Nginx并不占优势。
12.1 安装MySQL
LNMP中MySQL的安装步骤和LAMP一样
- 下载软件包：
[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz //下载mysql二进制包- 初始化：
[root@localhost src]# tar zxf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz //解压二进制包

[root@localhost src]# useradd -s /sbin/nologin mysql //创建用户mysql
[root@localhost src]# cd /usr/local/mysql
[root@localhost mysql]# mkdir -p /data/mysql //创建datadir，数据库文件会放到这里
[root@localhost mysql]# chown -R mysql:mysql /data/mysql //更改权限，否则后面会出问题
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql //这里datadir尽量使用绝对路径，不然后面可能报错
FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db:
