Dokcer容器分布式搭建LNMP+wordpress论坛

以下是使用Docker搭建LNMP环境并部署WordPress论坛的基本步骤：

1. 安装Docker：确保你的系统上安装了Docker。
2. 编写docker-compose.yml文件：

version: '3'
 
services:
  nginx:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./html:/usr/share/nginx/html
    depends_on:
      - php
      - mysql
    networks:
      - lnmp-network
 
  php:
    image: php:7.4-fpm
    volumes:
      - ./html:/usr/share/nginx/html
    networks:
      - lnmp-network
 
  mysql:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: wordpress
      MYSQL_USER: user
      MYSQL_PASSWORD: password
    volumes:
      - dbdata:/var/lib/mysql
    networks:
      - lnmp-network
 
volumes:
  dbdata:
 
networks:
  lnmp-network:
    driver: bridge

3. 创建nginx目录并编写配置文件default.conf：

server {
    listen       80;
    server_name  localhost;
 
    location / {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;
        try_files $uri $uri/ /index.php?$args;
    }
 
    error_page  404              /404.html;
 
    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
        include        fastcgi_params;
    }
}

4. 在html目录中创建index.php文件，用于连接MySQL和处理WordPress安装：

<?php
  define('DB_NAME', 'wordpress');
  define('DB_USER', 'user');
  define('DB_PASSWORD', 'password');
  define('DB_HOST', 'mysql');
  define('DB_CHARSET', 'utf8');
  define('DB_COLLATE', '');
  define('AUTH_KEY',         'put your unique key here');
  define('SECURE_AUTH_KEY',  'put your unique key here');
  define('LOGGED_IN_KEY',    'put your unique key here');
  define('NONCE_KEY',        'put your unique key here');
  define('AUTH_SALT',        'put your unique key here');
  define('SECURE_AUTH_SALT', 'put your unique key here');
  define('LOGGED_IN_SALT',   'put your unique key here');
  define('NONCE_SALT',       'put your unique key here');
  $table_prefix  = 'wp_';
  define('WPLANG', '');
  define('WP_DEBUG', false);
  if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/wordpress/');
  require_once(ABSPATH . 'wp-settings.php');
?>

5. 在终端中运行以下命令来启动Docker容器：

docker-compose up -d
