我在尝试设置PassengerTempDir时遇到了麻烦：
我对apache + mod_passenger，CentOs有所了解。在redmine中，我在上传文件时有500个内部错误。由于我的问题，我发现我应该将PassengerTempDir更改为自定义文件夹。
wrong permissions set in the webserver_private directory of passenger.
对于测试，我创建了文件夹/ home / tmp_passenger并为其设置了777。
然后我继续export PASSENGER_TMPDIR=/tmp_passenger
结果是：
passenger-status
ERROR: Phusion Passenger doesn't seem to be running.
所以，在我继续export PASSENGER_TMPDIR=/tmp_passenger之前
passenger-status

我继续export PASSENGER_TMPDIR=/tmp_passenger
passenger-status

请帮我解决问题。我现在该怎么办？
