set umask for tomcat8 via tomcat.service
I am trying to set a custom umask for a tomcat 8 instance, tried to make it the good way by using the UMask directive in systemd tomcat unit as seen here without luck.
I'd like to set a 022 umask cause the company dev needs to access tomcat / application logs and they are not in the same group as the tomcat user....
the crazy thing is that the systemd doc says :
Controls the file mode creation mask. Takes an access mode in octal notation. See umask(2) for details. Defaults to 0022.
But the logs (application / tomcat) are set to 640 (not the expected 755) :
-rw-r----- 1 top top 21416 Feb 1 09:58 catalina.out
My service file :
# Systemd unit file for tomcat
[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target
[...]
User=top
Group=top
UMask=0022
[Install]
WantedBy=multi-user.target
Any thoughts about this ?
Thanks

Try adding UMASK as Environment variable into tomcat's service file:
[Service]
...
Environment='UMASK=0022'
...
Default catalina.sh is checking for environment's $UMASK:
# Set UMASK unless it has been overridden
if [ -z "$UMASK" ]; then
UMASK="0027"
fi
umask $UMASK
(It seems to me, that UMask from systemd is not used by Tomcat, but I am not completely sure.)
