PHP环境Docker化怎么写

  1. 基础项目结构
  2. PHP Dockerfile
  3. PHP配置文件
  4. docker-compose.yml（开发环境）
  5. docker-compose.prod.yml（生产环境）
  6. 生产环境Dockerfile
  7. 生产环境PHP配置
  8. Nginx配置
  9. 环境变量文件
  10. 常用命令
  11. .dockerignore文件

我来提供一个完整的PHP环境Docker化方案,包含开发环境和生产环境的配置。

生产环境Dockerfile

# 非root用户运行
RUN usermod -u 1000 www-data && groupmod -g 1000 www-data

生产环境PHP配置

; docker/php/php.prod.ini
upload_max_filesize = 20M
post_max_size = 20M
max_execution_time = 300
memory_limit = 256M
date.timezone = Asia/Shanghai
; 生产环境配置
display_errors = Off
log_errors = On
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
error_log = /var/log/php/error.log
; OpCache配置（生产优化）
opcache.enable = 1
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 16
opcache.max_accelerated_files = 10000
opcache.revalidate_freq = 60
opcache.fast_shutdown = 1
opcache.validate_timestamps = 0
; 安全配置
expose_php = Off
session.cookie_httponly = 1
session.use_strict_mode = 1

Nginx配置

# docker/nginx/conf.d/default.conf
server {
    listen 80;
    server_name localhost;
    root /var/www/html;
    index index.php index.html;
    # 日志配置
    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
    # 静态文件缓存
    location ~* \.(jpg|jpeg|png|gif|ico|css|js|woff|woff2|ttf|svg)$ {
        expires 30d;
        add_header Cache-Control "public, no-transform";
    }
    # PHP配置
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param APP_ENV development;
    }
    # 其他配置
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
    location ~ /\.(?!well-known).* {
        deny all;
    }
}

环境变量文件

# .env.example
# 项目配置
PROJECT_NAME=php_app
# 端口配置
NGINX_PORT=8080
MYSQL_PORT=3306
REDIS_PORT=6379
# MySQL配置
MYSQL_ROOT_PASSWORD=root_password
MYSQL_DATABASE=app_database
MYSQL_USER=app_user
MYSQL_PASSWORD=app_password
# Redis配置
REDIS_PASSWORD=redis_password

常用命令

# 启动开发环境
docker-compose up -d
# 查看状态
docker-compose ps
# 查看日志
docker-compose logs -f
# 进入PHP容器
docker-compose exec php bash
# 运行Composer命令
docker-compose exec php composer install
# 运行Artisan命令（Laravel）
docker-compose exec php php artisan migrate
# 停止服务
docker-compose stop
# 重新构建
docker-compose up -d --build
# 生产环境
docker-compose -f docker-compose.prod.yml up -d
# 一键部署脚本
#!/bin/bash
# deploy.sh
echo "开始部署..."
git pull origin main
docker-compose -f docker-compose.prod.yml up -d --build
docker-compose -f docker-compose.prod.yml exec php php artisan migrate --force
docker-compose -f docker-compose.prod.yml exec php php artisan config:cache
docker-compose -f docker-compose.prod.yml exec php php artisan route:cache
docker-compose -f docker-compose.prod.yml exec php php artisan view:cache
echo "部署完成！"

.dockerignore文件

.git
.gitignore
.env
.env.*
!.env.example
node_modules
vendor
storage
*.log
.DS_Store
docker-compose*.yml

这个方案提供了：

  • 完整的开发环境（含Xdebug调试）
  • 生产环境优化配置
  • 多服务容器编排
  • 数据持久化
  • 环境变量管理
  • 一键部署支持

你可以根据项目需求（Laravel、WordPress、ThinkPHP等）调整配置。
