# 如何修改默认的8090端口 ​

docker-compose 修改映射端口会播放失败

    ports:
          - 80:8090

从日志看继续调用了 http://10.0.0.4:8090 而不是修改映射的80，还原成

    ports:
          - 8090:8090

则一切正常

需要添加环境变量

    environment:
        XIAOMUSIC_PORT:80
    ports:
          - 80:80

自己走了点弯路，半天才搞明白。补充说明：

> environment: XIAOMUSIC_PORT: 5678 #就是“5678”可以根据自己要求设置，但要求上下的5678都设置成一个 ports: - 5678:5678

如果换端口，需要3个数字一致，比如

    environment:
        XIAOMUSIC_PORT:6874
    ports:
          - 6874:6874

文档类型的我都打开下，方便其他人看到。

docker-compose 中对应关系应该是

yaml

    ports:
        - aaaa:bbbb
    environment:
        XIAOMUSIC_PORT: bbbb  # 配置文件中的 port，后台：监听端口(修改后需要重启)
        XIAOMUSIC_PUBLIC_PORT: aaaa # 配置文件中的 public_port，后台：外网访问端口(0表示跟监听端口一致)

以上，docker 环境中基本不存在需要修改 bbbb 的情况，也就是不用设置 XIAOMUSIC_PORT。如果需要修改端口，只需要修改两处 aaaa 如果使用反向代理，则转发 localhost:aaaa，XIAOMUSIC_PUBLIC_PORT 设置成代理的监听端口 cccc

另外，setting 文件存在会覆盖环境变量。启动过之后需要直接修改 settings.json 或者在后台修改
