使用Docker Compose编排LNMP（Linux, Nginx, MySQL, PHP）环境并部署WordPress，是一个非常高效的解决方案。本文将详细介绍如何编写Dockerfile和docker-compose.yml文件来完成这一任务。
环境准备
确保已经安装了以下工具：
- Docker
- Docker Compose
创建项目目录结构
首先，创建一个项目目录，并在其中创建所需的文件和子目录。
lnmp-wordpress/
├── docker-compose.yml
├── nginx/
│ ├── Dockerfile
│ └── nginx.conf
├── php/
│ └── Dockerfile
└── wordpress/├── Dockerfile└── wp-config.php
编写Nginx的Dockerfile和配置文件
nginx/Dockerfile
FROM nginx:latest
COPY nginx.conf /etc/nginx/nginx.conf
nginx/nginx.conf
server {listen 80;server_name localhost;root /var/www/html;index index.php index.html index.htm;location / {try_files $uri $uri/ /index.php?$args;}location ~ .php$ {include snippets/fastcgi-php.conf;fastcgi_pass php:9000;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}location ~ /.ht {deny all;}
}
编写PHP的Dockerfile
php/Dockerfile
FROM php:7.4-fpm
RUN docker-php-ext-install mysqli
编写WordPress的Dockerfile和配置文件
wordpress/Dockerfile
FROM wordpress:latest
COPY wp-config.php /var/www/html/wp-config.php
wordpress/wp-config.php
<?php
define('DB_NAME', 'wordpress');
define('DB_USER', 'root');
define('DB_PASSWORD', 'root');
define('DB_HOST', 'mysql');
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');define('AUTH_KEY', 'put your unique phrase here');
define('SECURE_AUTH_KEY', 'put your unique phrase here');
define('LOGGED_IN_KEY', 'put your unique phrase here');
define('NONCE_KEY', 'put your unique phrase here');
define('AUTH_SALT', 'put your unique phrase here');
define('SECURE_AUTH_SALT', 'put your unique phrase here');
define('LOGGED_IN_SALT', 'put your unique phrase here');
define('NONCE_SALT', 'put your unique phrase here');$table_prefix = 'wp_';define('WP_DEBUG', false);if ( !defined('ABSPATH') )define('ABSPATH', dirname(__FILE__) . '/');require_once(ABSPATH . 'wp-settings.php');
编写Docker Compose文件
docker-compose.yml
version: '3.8'services:nginx:build:context: ./nginxports:- "80:80"volumes:- ./wordpress:/var/www/htmldepends_on:- php- mysqlphp:build:context: ./phpvolumes:- ./wordpress:/var/www/htmlmysql:image: mysql:5.7volumes:- mysql_data:/var/lib/mysqlenvironment:MYSQL_ROOT_PASSWORD: rootMYSQL_DATABASE: wordpresswordpress:build:context: ./wordpressvolumes:- ./wordpress:/var/www/htmldepends_on:- mysqlvolumes:mysql_data:
启动服务
在项目根目录中运行以下命令启动服务：
docker-compose up -d
该命令将构建和启动Nginx、PHP、MySQL和WordPress容器。启动完成后，可以在浏览器中访问 http://localhost来设置和使用WordPress。
