Question

我设置了气流以使用celeryExecuter执行工作流。我已经启动了Web服务器，调度程序和工作程序，它们运行得很好。但是Flower UI不会显示任何工人。

airflow worker的输出是：

/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>.

airflow flower的输出为：

但是flower不会显示有关工作者或任务的任何信息，并且会在CLI上产生以下错误：

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

有什么问题的想法吗？

嗯，我能够解决问题。原来我应该在运行该工作程序之前将export C_FORCE_ROOT=true添加到我的~/.bashrc文件中。当您以超级用户身份执行工作程序时，就会发生这种情况。
