Laravel Sail Docker环境下PHPMyAdmin内存不足错误排查求助

错误信息 #

访问http://localhost:8888/时：

Fatal error: Out of memory (allocated 2097152 bytes) (tried to allocate 81920 bytes) in /var/www/html/vendor/composer/autoload_static.php on line 421

刷新后：

PHP Fatal error:  Out of memory (allocated 2097152 bytes) (tried to allocate 65536 bytes) in /var/www/html/vendor/composer/autoload_real.php on line 33

已尝试的解决方法 #

• 重启Sail：执行sail restart
• 无缓存重建镜像：执行sail build --no-cache和sail up -d
• 在docker-compose.yml的phpmyadmin服务中添加环境变量PHP_MEMORY_LIMIT: 1G，重启后无效
• 自定义PHP配置文件：
  • 创建./phpmyadmin/phpmyadmin-misc.ini和./phpmyadmin/sessions目录
  • 在docker-compose.yml的phpmyadmin服务中挂载卷：

    volumes:
      - ./phpmyadmin/sessions:/sessions
      - ./phpmyadmin/phpmyadmin-misc.ini:/usr/local/etc/php/conf.d/phpmyadmin-misc.ini
    

  • phpmyadmin-misc.ini内容：

    allow_url_fopen = Off
    max_execution_time = 600
    memory_limit = 64M
    post_max_size = 64M
    upload_max_filesize = 64M
    

  • 重启后无效
• 设置Docker资源限制：在phpmyadmin服务中添加deploy配置：

  phpmyadmin:
      image: phpmyadmin/phpmyadmin:5.2.1
      deploy:
          resources:
              limits:
                  cpus: '0.50'
                  memory: 50M
              reservations:
                  cpus: '0.25'
                  memory: 20M
  

  • 重启后无效
• 直接修改容器内php.ini：
  1. 进入容器：sail exec phpmyadmin bash
  2. 创建phpinfo文件：echo "<?php phpinfo(); ?>" > info.php
  3. 访问http://localhost:8888/info.php确认php.ini路径为/usr/local/etc/php
  4. 复制生产环境配置：cp php.ini-production php.ini
  5. 安装vim并修改memory_limit=2048M
  6. 退出容器并执行sail restart
  • 重启后无效
