How to change file permission for apache log rotation

Question

From my linux server, I deployed one web application on tomcat server. And I configured log4j to write log and rotate every hour. But when it create new log every times, it use "640" file permission by default.

rw-r----- 1 myuser myuser 664 Jun 6 11:00 mylog.log

I am not quite sure where the configuration did for log rotation with 640 permission. I didn't define in my log4j configuration.

Please kindly advise me where I can change file permission for newly log rotation of my log4j files?

Thanks, Tun

File permissions are determined by the tomcat7 user's umask - there's no way to change it in log4j itself.

Thanks. Now my umask is 027. Do I need to change to 022 to allow read permission to others? May be it will become -rw-r--r--? – Eido Shack Sep 20 '16 at 11:21
`umask 0022` will make it read only to group and others and executable\readable\writable for the owner. – Shmulik Klein Sep 20 '16 at 11:28
Thanks. It will be 644, correct? Is it necessary to restart server after configuration changed? – Eido Shack Sep 20 '16 at 11:30
Right (I was wrong - it won't be executable..). If you changed it in `startup.sh` so yes, you should restart Tomcat. – Shmulik Klein Sep 20 '16 at 11:35
