求助：Docker Compose部署的WordPress无法通过192.168.0.x IPv4访问

各位社区成员好！
我使用Docker Compose在本地环境搭建了一个小型WordPress应用。
我尝试配置docker-compose.yml，让应用可通过192.168.0.x这类外部IPv4地址访问，但目前仅能通过以下方式访问：

• http://localhost
• http://127.0.0.1
• http://0.0.0.0

是否可以通过无线局域网（WLAN）的外部IP访问该应用？

例如：http://192.168.0.13 或 http://192.168.65.10

以下是我的docker-compose.yml配置文件（配置后WLAN IPv4地址192.168.65.10无法访问）：

version: '3'

        ipv4_address: 172.30.9.3
      lan:
        ipv4_address: 192.168.65.10

networks:
  internal:
    ipam:
      config:
        - subnet: 172.30.9.0/29
  lan:
    name: lan
    driver: ipvlan
    driver_opts:
      parent: eth0.10
      ipvlan_mode: l2
    ipam:
      config:
        - subnet: "192.168.65.0/24"
          gateway: "192.168.65.1"

1. 修正ipvlan网络的父接口配置 #

你当前配置的parent: eth0.10是VLAN子接口，如果你的WLAN并没有使用该VLAN（比如无线网卡是wlan0），这个配置会失效：

• 用ip link show命令查看主机实际的无线网卡名称（通常是wlan0）
• 将lan网络的parent字段替换为实际无线网卡名称

2. 移除冲突的端口映射 #

wp服务同时配置了ports: -80:80和ipvlan固定IP，两种方式冲突。如果用ipvlan让容器直接获取局域网IP，无需端口映射，删掉ports: -80:80这一行。

3. 配置WordPress站点地址 #

即使容器能被局域网访问，WordPress默认的localhost地址会导致跳转异常，需要在wp服务的环境变量中添加：

WORDPRESS_SITE_URL: http://192.168.65.10
WORDPRESS_HOME: http://192.168.65.10

4. 检查防火墙与权限 #

• 主机防火墙需放行80端口，Linux下可执行sudo ufw allow 80/tcp
• 确保启动容器时使用管理员权限（Linux下加sudo）

        - subnet: "192.168.65.0/24"

验证步骤 #

1. 重启容器：docker-compose down && docker-compose up -d
2. 在局域网内其他设备访问http://192.168.65.10，确认是否能正常打开WordPress页面。
