redis - 将 redis 与 Bokeh 服务器一起使用。权限被拒绝 : '/bokehpids.json'

Question

我正在尝试使用 supervisor 以 redis 作为后端来运行 bokeh-server，但在启动时收到此错误消息:

Traceback (most recent call last):
  File "/usr/share/nginx/test-status/flask/bin/bokeh-server", line 7, in <module>
    bokeh.server.run()
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/__init__.py", line 175, in run
    start_server(args)
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/__init__.py", line 179, in start_server
    start.start_simple_server(args)
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/start.py", line 54, in start_simple_server
    start_redis()

    save=redis_save)
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/services.py", line 81, in start_redis
    stdin=subprocess.PIPE
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/services.py", line 32, in __init__
    self.add_to_pidfile()
  File "/usr/share/nginx/test-status/flask/lib/python2.7/site-packages/bokeh/server/services.py", line 46, in add_to_pidfile
    with open(self.pidfilename, "w+") as f:
IOError: [Errno 13] Permission denied: '/bokehpids.json'

请注意，如果我使用内存作为后端，我可以使用 supervisor 运行服务器，并且我可以使用 redis 作为后端手动运行 bokeh-server 就好了。有谁知道我应该更改的权限在哪里？

原来它试图访问根目录中的 pid 文件......

我通过更改主管配置文件中的目录解决了这个问题:

[program:bokeh]
...
    directory=/usr/share/nginx/test-status
...
