12.1 LNMP架构介绍

• 和LAMP不同的是，提供web服务的是Nginx
• 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

12.2 MySQL安装

二进制免编译包安装

[root@localhost ~]# cd /usr/local/src/
[root@localhost src]# wget https://mirrors.tuna.tsinghua.edu.cn/mysql/downloads/MySQL-5.6/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@localhost src]# ls
mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@localhost src]# tar xzvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@localhost src]# mv mysql-5.6.39-linux-glibc2.12-x86_64 /usr/local/mysql
[root@localhost src]# ls /usr/local/mysql/
bin  COPYING  data  docs  include  lib  man  mysql-test  README  scripts  share  sql-bench  support-files
[root@localhost src]# useradd mysql
[root@localhost src]# mkdir /data/
[root@localhost src]# cd /usr/local/mysql/
[root@localhost mysql]# yum install -y perl-Data-Dumper
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/data/mysql
[root@localhost mysql]# echo $?
0
[root@localhost mysql]# cp support-files/my-default.cnf  /etc/my.cnf
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# vim /etc/my.cnf
[mysqld]
basedir = /usr/local/mysql
datadir = /data/mysql
socket = /tmp/mysql.sock

[root@localhost mysql]# vim /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql

[root@localhost mysql]# chkconfig --add mysqld
[root@localhost ~]# service mysqld start
Starting MySQL. SUCCESS! 

12.3/12.4 PHP安装

[root@localhost src]# tar zxf php-5.6.30.tar.gz
[root@localhost src]# yum install -y libxml2-devel openssl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel bzip2-devel libcurl-devel

[root@localhost php-5.6.30]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@localhost php-5.6.30]# chmod 755 /etc/init.d/php-fpm

[root@localhost php-5.6.30]# chkconfig php-fpm on

12.5 Nginx介绍

• Nginx官网 nginx.org，最新版1.13，最新稳定版1.12
• Nginx应用场景：web服务、反向代理、负载均衡
• Nginx著名分支，淘宝基于Nginx开发的Tengine，使用上和Nginx一致，服务名，配置文件名都一样，和Nginx的最大区别在于Tenging增加了一些定制化模块，在安全限速方面表现突出，另外它支持对js，css合并
• Nginx核心+lua相关的组件和模块组成了一个支持lua的高性能web容器openresty，参考http://jinnianshilongnian.iteye.com/blog/2280928
