Rails Error: Unable to access log file... in Apache error log file


My Rails Depot app is working fine using WEBrick server but with
Apache2, the app is having problems with writing to the development.log
file. When using WEBrick, the development.log shows the logging
consistently, but when using Apache2, nothing shows in the
development.log file. On checking the Apache error log, I get this:

[Sat Nov 25 10:24:38 2006] [error] [client] Rails Error:
Unable to access log file. Please ensure that
/srv/www/htdocs/depot/../config/../log/development.log exists and is
chmod 0666. The log level has been raised to WARN and the output
directed to STDERR until the problem is fixed.

I am a newbie to RoR and Linux as well (about 3 weeks). I have
performed "chown, and chgrp and chmod" on the log directory and "ls -l
/srv/www/rails/depot/log" produced the following:
-rw-rw-rw- 1 wwwrun www 442996 2006-11-23 17:37 development.log
-rw-rw-rw- 1 wwwrun www 0 2006-11-20 22:34 production.log
-rw-rw-rw- 1 wwwrun www 0 2006-11-20 22:34 server.log
-rw-rw-rw- 1 wwwrun www 0 2006-11-20 22:34 test.log

What am I missing here?


Hi Leng, the webrick server may have an exclusive lock on the
development.log file. Also, you cannot change the file’s
permission to gain write access to a file that has a exclusive
lock. My recommendation would be to allow Apache and Webrick to
write to their own respective log files because it makes it easier to
debug the application in question.

Good luck,
