准备 LNMP 环境
LNMP 是 Linux、Nginx、MySQL 和 PHP 的缩写，是 WordPress 博客系统依赖的基础运行环境。我们先来准备 LNMP 环境
安装 Nginx
使用 yum 安装 Nginx：
yum install nginx -y
修改 /etc/nginx/conf.d/default.conf，去除对 IPv6 地址的监听
，可参考下面的示例：
default.conf
3456789101112131415161718192021
# listen [::]:80 default_server; server_name _; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } }
查找
server {
listen 80 default_server;
# listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
修改完成后，启动 Nginx：
nginx
此时，可访问实验机器外网 HTTP 服务（http://182.254.232.147）来确认是否已经安装成功。
将 Nginx 设置为开机自动启动：
chkconfig nginx on
使用 yum 安装 MySQL：
yum install mysql-server -y
安装完成后，启动 MySQL 服务：
service mysqld restart
设置 MySQL 账户 root 密码：
/usr/bin/mysqladmin -u root password 'MyPas$word4Word_Press'
将 MySQL 设置为开机自动启动：
chkconfig mysqld on
安装 PHP
使用 yum 安装 PHP：
yum install php-fpm php-mysql -y
安装之后，启动 PHP-FPM 进程：
service php-fpm start
启动之后，可以使用下面的命令查看 PHP-FPM 进程监听哪个端口
netstat -nlpt | grep php-fpm
把 PHP-FPM 也设置成开机自动启动：
chkconfig php-fpm on
安装 WordPress
配置好 LNMP 环境后，继续使用 yum 来安装 WordPress：
yum install wordpress -y
安装完成后，就可以在 /usr/share/wordpress 看到 WordPress 的源代码了。
配置数据库
进入 MySQL：
mysql -uroot --password='MyPas$word4Word_Press'
为 WordPress 创建一个数据库：
CREATE DATABASE wordpress;
MySQL 部分设置完了，我们退出 MySQL 环境：
exit
把上述的 DB 配置同步到 WordPress 的配置文件中，可参考下面的配置：
wp-config.php
<?php
/**
* The base configuration for WordPress
*
* The wp-config.php creation script uses this file during the
* installation. You don't have to use the web site, you can
* copy this file to "wp-config.php" and fill in the values.
*
* This file contains the following configurations:
*
* * MySQL settings
* * Secret keys

* * ABSPATH

define('DB_COLLATE', '');

define('NONCE_SALT', 'put your unique phrase here');
/**#@-*/
/**

*/
$table_prefix = 'wp_';

*/
define('WP_DEBUG', false);
/* That's all, stop editing! Happy blogging. */
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
define('ABSPATH', '/usr/share/wordpress');
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
配置 Nginx
WordPress 已经安装完毕，我们配置 Nginx 把请求转发给 PHP-FPM 来处理
首先，重命名默认的配置文件：
cd /etc/nginx/conf.d/
mv default.conf defaut.conf.bak
在 /etc/nginx/conf.d 创建 wordpress.conf 配置，参考下面的内容：
wordpress.conf
配置后，通知 Nginx 进程重新加载：
nginx -s reload
