【问题描述】：

我已设置气流以使用 celeryExecuter 执行工作流。我已经启动了网络服务器、调度程序和工作程序，它们运行得很好。但是花 UI 没有显示任何工人。

airflow worker 的输出为：

/usr/local/lib/python2.7/dist-packages/psycopg2/__init__.py:144: UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: <http://initd.org/psycopg/docs/install.html#binary-install-from-pypi>.

而airflow flower的输出是：

但是 Flower 没有显示任何有关工作人员或任务的信息，并在 CLI 上生成以下错误：

[E 180802 11:29:55 broker:82] RabbitMQ 管理 API 调用失败： [Errno 111] 连接被拒绝

有什么想法吗？

好吧，我能够解决这个问题。事实证明，我应该在运行工作程序之前将export C_FORCE_ROOT=true 添加到我的~/.bashrc 文件中。当您以 root 身份执行 worker 时会发生这种情况。
