准备 LNMP 环境

任务时间:30min ~ 60min

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:

  1. 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:
示例代码:/etc/nginx/conf.d/default.conf

  1. server {
  2. listen 80 default_server;
  3. # listen [::]:80 default_server;
  4. server_name _;
  5. root /usr/share/nginx/html;
  6.  
  7. # Load configuration files for the default server block.
  8. include /etc/nginx/default.d/*.conf;
  9.  
  10. location / {
  11. }
  12.  
  13. error_page 404 /404.html;
  14. location = /40x.html {
  15. }
  16.  
  17. error_page 500 502 503 504 /50x.html;
  18. location = /50x.html {
  19. }
  20.  
  21. }

修改完成后,启动 Nginx:

  1. nginx

此时,可访问实验机器外网 HTTP 服务(https://<您的 CVM IP 地址>)来确认是否已经安装成功。
将 Nginx 设置为开机自动启动:

  1. chkconfig nginx on

CentOS 6 不支持 IPv6,需要取消对 IPv6 地址的监听,否则 Nginx 不能成功启动。

安装 MySQL
使用 yum 安装 MySQL:

  1. yum install mysql-server -y

安装完成后,启动 MySQL 服务:

  1. service mysqld restart

设置 MySQL 账户 root 密码:

  1. /usr/bin/mysqladmin -u root password 'MyPas$word4Word_Press'

将 MySQL 设置为开机自动启动:

  1. chkconfig mysqld on
下面命令中的密码是教程为您自动生成的,为了方便实验的进行,不建议使用其它密码。如果设置其它密码,请把密码记住,在后续的步骤会使用到。

安装 PHP

使用 yum 安装 PHP:

  1. yum install php-fpm php-mysql -y

安装之后,启动 PHP-FPM 进程:

  1. 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

  1. netstat -nlpt | grep php-fpm

把 PHP-FPM 也设置成开机自动启动:

  1. chkconfig php-fpm on

CentOs 6 默认已经安装了 PHP-FPM 及 PHP-MYSQL,下面命令执行的可能会提示已经安装。
PHP-FPM 默认监听 9000 端口

安装并配置 WordPress

任务时间:30min ~ 60min

安装 WordPress

配置好 LNMP 环境后,继续使用 yum 来安装 WordPress:

  1. 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:

  1. mysql -uroot --password='MyPas$word4Word_Press'

为 WordPress 创建一个数据库:

  1. CREATE DATABASE wordpress;

MySQL 部分设置完了,我们退出 MySQL 环境:

  1. 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:

示例代码:/etc/wordpress/wp-config.php

  1. <?php
  2. /**
  3. * The base configuration for WordPress
  4. *
  5. * The wp-config.php creation script uses this file during the
  6. * installation. You don't have to use the web site, you can
  7. * copy this file to "wp-config.php" and fill in the values.
  8. *
  9. * This file contains the following configurations:
  10. *
  11. * * MySQL settings
  12. * * Secret keys
  13. * * Database table prefix
  14. * * ABSPATH
  15. *
  16. * @link https://codex.wordpress.org/Editing_wp-config.php
  17. *
  18. * @package WordPress
  19. */

  21. // ** MySQL settings - You can get this info from your web host ** //
  22. /** The name of the database for WordPress */
  23. define('DB_NAME', 'wordpress');
  24.  
  25. /** MySQL database username */
  26. define('DB_USER', 'root');
  27.

  29. define('DB_PASSWORD', 'MyPas$word4Word_Press');
  30.

  32. define('DB_HOST', 'localhost');
  33.  
  34. /** Database Charset to use in creating database tables. */
  35. define('DB_CHARSET', 'utf8');

  38. define('DB_COLLATE', '');

  49. define('AUTH_KEY', 'put your unique phrase here');
  50. define('SECURE_AUTH_KEY', 'put your unique phrase here');

  66. $table_prefix = 'wp_';
  67.  
  68. /**

  72. /* Disable all file change, as RPM base installation are read-only */
  73. define('DISALLOW_FILE_MODS', true);
  74.  
  75. /* Disable automatic updater, in case you want to allow
  76. above FILE_MODS for plugins, themes, ... */
  77. define('AUTOMATIC_UPDATER_DISABLED', true);
  78.  
  79. /* Core update is always disabled, WP_AUTO_UPDATE_CORE value is ignore */
  80.  
  81. /**

  90. *

  92. */
  93. define('WP_DEBUG', false);
  94.  
  95. /* That's all, stop editing! Happy blogging. */
  96.  
  97. /** Absolute path to the WordPress directory. */
  98. if ( !defined('ABSPATH') )
  99. define('ABSPATH', '/usr/share/wordpress');
  100.  
  101. /** Sets up WordPress vars and included files. */
  102. require_once(ABSPATH . 'wp-settings.php');
如果你上面的步骤没有使用教程创建的密码,请修改下面命令中的密码登录

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:

  1. cd /etc/nginx/conf.d/
  2. mv default.conf defaut.conf.bak

在 /etc/nginx/conf.d 创建 wordpress.conf 配置,参考下面的内容:

示例代码:/etc/nginx/conf.d/wordpress.conf
  1. server {
  2. listen 80;
  3. root /usr/share/wordpress;
  4. location / {
  5. index index.php index.html index.htm;
  6. try_files $uri $uri/ /index.php index.php;
  7. }
  8. # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
  9. location ~ .php$ {
  10. fastcgi_pass 127.0.0.1:9000;
  11. fastcgi_index index.php;
  12. fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  13. include fastcgi_params;
  14. }
  15. }

配置后,通知 Nginx 进程重新加载:

  1. nginx -s reload
默认的 Server 监听 80 端口,与 WordPress 的服务端口冲突,将其重命名为 .bak 后缀以禁用默认配置
