Hello,

Iam thinking of setting a umask in nginx… so that it writes files  
(logs ans cache) in 770 . Anybody know how to do this, or done it?

I need this because my environment needs access to all files produced by  
nginx and some are 700 .

Regards,  
Mike

Never tried but maybe set the umask at the beginning of the init.d  
script (but that would apply to all files creation)…  
Or a quick/dirty way to do it would be to chmod 770 the log files every  
x hour or once a day from a cron job…

I tried this in the init script:

su - nginx -c “umask 002”;  
umask 002;

None of them work… new cache files/dir still get 700 permissions…

What could i be doing wrong=?
