我在 debian 8.9 / apache2 下运行 wsgi 应用程序，应用程序 (LinOTP) 没有写入日志文件。我不确定这是应用程序的问题还是设置问题。我在 apache error.log 中看到错误
root@host:/var/log/apache2# tail -f /var/log/apache2/error.log

以下是应用程序 .ini 中的日志配置：
## Logging Configuration:
## ----------------------
## Note: For more detailed log messages change the level to INFO or DEBUG
##
## Logger configuration
## - define which modules should be logged
[loggers]
keys = root
## root module logging definition:
[logger_root]
level = DEBUG
handlers = file
[handlers]
keys = file
[handler_file]
class = handlers.RotatingFileHandler
# Make the logfiles 10 MB
#and rotate 4 files
args = ('/var/log/linotp/linotp.log','a', 10000000, 4)
level = WARN
formatter = generic
## Logging via logstash
## This is an example using the python-logstash logging library.
## If you wish to use this example, you also need to add
## logstash to handlers.keys, and add the logstash handler to
## the individual logger_* section
#[handler_logstash]
## Logging class to use
#class = logstash.UDPLogstashHandler
## Arguments as accepted by the logstash library. For more details
## see the output of 'pydoc logstash.UDPLogstashHandler'
## ('hostname', port, message_type, ('tag', 'tag', ...), fqdn, version)
#args = ('logstashhost', 5000, 'linotp', ('example1'), False, 1)
[formatters]
keys = generic
[formatter_generic]
## To secure your log output and prevent command escaping use the
## logger class definition linotp.lib.log.SecureFormatter by uncommenting the
## line below
##
## Caution: The SecureFormatter will only work with python >= 2.7
##
#class = linotp.lib.log.SecureFormatter
format = %(asctime)s %(levelname)-5.5s {%(request_id)s} [%(name)s][%(funcName)s #%(lineno)d] %(message)s
datefmt = %Y/%m/%d - %H:%M:%S
有人可以给我一些提示吗？
