基于CentOS搭建WordPress个人博客

1. 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：

  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 / {    }    error_page 404 /404.html;        location = /40x.html {    }    error_page 500 502 503 504 /50x.html;        location = /50x.html {    }}

  修改完成后，启动 Nginx：

  nginx

  此时，可访问云服务器外网 HTTP 服务（http://yourdomain.com）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

• 安装 MySQL

  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

2. 安装并配置 WordPress

• 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。

  由于上面的安装方法默认安装的是英文版，所以我们还要下载中文语言包，如果不需要中文安装可跳过此步骤

  wget https://cn.wordpress.org/wordpress-4.8.1-zh_CN.tar.gztar -zxvf wordpress*mv -r wordpress/wp-content/languages /usr/share/wordpress/wp-contentrm -rf wordpress*

• 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 wp-config.php 中，可参考下面的配置：

  <?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 * * Database table prefix * * ABSPATH * * @link https://codex.wordpress.org/Editing_wp-config.php * * @package WordPress */// ** MySQL settings - You can get this info from your web host ** ///** The name of the database for WordPress */define('DB_NAME', 'wordpress');/** MySQL database username */define('DB_USER', 'root');/** MySQL database password */define('DB_PASSWORD', 'MyPas$word4Word_Press');/** MySQL hostname */define('DB_HOST', 'localhost');/** Database Charset to use in creating database tables. */define('DB_CHARSET', 'utf8');/** The Database Collate type. Don't change this if in doubt. */define('DB_COLLATE', '');define('WPLANG', 'zh_CN');/**#@+ * Authentication Unique Keys and Salts. * * Change these to different unique phrases! * You can generate these using the {@link https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service} * You can change these at any point in time to invalidate all existing cookies.

Only numbers, letters, and underscores please! */$table_prefix  = 'wp_';/** * See http://make.wordpress.org/core/2013/10/25/the-definitive-guide-to-disabling-auto-updates-in-wordpress-3-7 *//* Disable all file change, as RPM base installation are read-only */define('DISALLOW_FILE_MODS', true);/* Disable automatic updater, in case you want to allow   above FILE_MODS for plugins, themes, ... */define('AUTOMATIC_UPDATER_DISABLED', true);/* Core update is always disabled, WP_AUTO_UPDATE_CORE value is ignore *//** * For developers: WordPress debugging mode. * * Change this to true to enable the display of notices during development. * It is strongly recommended that plugin and theme developers use WP_DEBUG * in their development environments. * * For information on other constants that can be used for debugging, * visit the Codex. * * @link https://codex.wordpress.org/Debugging_in_WordPress */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：

  server {    listen 80;    root /usr/share/wordpress;    location / {        index index.php index.html index.htm;        try_files $uri $uri/ /index.php index.php;    }    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000    location ~ .php$ {        fastcgi_pass   127.0.0.1:9000;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;        include        fastcgi_params;    }}

  配置后，通知 Nginx 进程重新加载：

  nginx -s reload
