wordpress采用docker部署，部署配置如下：

  claves-homepage:
    container_name: claves-homepage
    hostname:  claves-homepage
    image: wordpress:5.8.1-apache
    restart: always
    ports:
      - 8087:80
    deploy:
      resources:
        limits:
          cpus: '0.5'
          memory: 500M
        reservations:
          memory: 200M
    environment:
      WORDPRESS_DB_HOST: claves-mysql:4194
      WORDPRESS_DB_USER: claves-office
      WORDPRESS_DB_PASSWORD: gJR*TqU2rFDSAFASD
      WORDPRESS_DB_NAME: www_claves_com_cn
      WORDPRESS_TABLE_PREFIX: claves_site_
    volumes:
      - ./volumes/claves-homepage/www:/var/www/html:rw
      - ./volumes/claves-homepage/phpconf/custom.ini:/usr/local/etc/php/conf.d/custom.ini:rw
      - ./volumes/claves-homepage/apacheconf/000-default.conf:/etc/apache2/sites-enabled/000-default.conf:rw
    logging:
      options:
        max-size: "10240k"
        max-file: "3"
    networks:
      claves-switch:
        ipv4_address: 172.21.0.25

upload_max_filesize = 512M
post_max_size = 512M
upload_max_size = 512M
