Description Joe Madden 2017-12-07 09:26:28 UTC 
Description of problem:

Installing a service called ntis-adapter the - causes issues with systemd/tomcat start/stop where by it does not load the specific configuration in /etc/sysconfig/tomcat@ntis-adapter



Version-Release number of selected component (if applicable):

systemd-219-42.el7_4.4.x86_64
tomcat-7.0.76-3.el7_4.noarch

How reproducible:


Steps to Reproduce:
1. Create tomcat service with a - in the name using this RHEL soloution (https://access.redhat.com/solutions/2386441)

2. Attempt to start the service - Errors will occour as it will look in /var/lib/tomcats instead of looking at the correct CATALINA_BASE

3. Rename the service removing the - and rename the configuration in /etc/sysconfig

4. Start the service - It works and loads in the configuration values correctly

Actual results:

Additional info:


/etc/sysconfig/tomcat@ntis-service

# Service-specific configuration file for tomcat. This will be sourced by
# the SysV init script after the global configuration file
# /etc/tomcat/tomcat.conf, thus allowing values to be overridden in
# a per-service manner.
#
# NEVER change the init script itself. To change values for all services make
# your changes in /etc/tomcat/tomcat.conf
#
# To change values for a specific service make your edits here.
# To create a new service create a link from /etc/init.d/<your new service> to
# /etc/init.d/tomcat (do not copy the init script) and make a copy of the
# /etc/sysconfig/tomcat file to /etc/sysconfig/<your new service> and change
# the property values so the two services won't conflict. Register the new
# service in the system as usual (see chkconfig and similars).

Comment 2 Lukáš Nykrýn 2017-12-07 09:34:11 UTC 
If I am not mistaken, we don't support variable expansion in environment files, so this:
JAVA_OPTS="${JAVA_OPTS} -Dspring.profiles.active=live,default -Duser.timezone=Europe/London -Dlog4j.configuration=file:${CATALINA_BASE}/conf/ntis-adapter/log4j.xml"
and
CATALINA_TMPDIR="${CATALINA_BASE}/temp"
can't work.
Comment 3 Joe Madden 2017-12-07 09:36:08 UTC 
Yep - your correct. I've just fixed this in my config.

Please note this is not about my service not working, currently in the process of fixing it but it wouldn't load any of the virables while i had a dash in the service name.

Removed that and it is now loading CATALINA_BASE


Thanks
Comment 4 Lukáš Nykrýn 2017-12-07 11:28:47 UTC 
Hmm, looks like there is a bug.

Minimal reproducer:
[root@qeos-13 system]# cat /etc/systemd/system/test@.service
[Service]
EnvironmentFile=/etc/sysconfig/test%I
Type=oneshot
ExecStart=/usr/bin/env
[root@qeos-13 system]# touch /etc/sysconfig/testa-a
[root@qeos-13 system]# systemctl start test
Job for test failed because a configured resource limit was exceeded. See "systemctl status test" and "journalctl -xe" for details.

The same problem seems to be also in upstream version of systemd (systemd-235-4.fc28.x86_64)
Comment 5 Lukáš Nykrýn 2017-12-07 13:33:41 UTC 
Ok, so the problem is not in systemd, it behaves correctly, although the error message is terrible and I had to look into the code to see what is actually wrong. But anyway. https://www.freedesktop.org/software/systemd/man/systemd.unit.html#Specifiers
"%i" - For instantiated units: this is the string between the "@" character and the suffix of the unit name.
"%I" - Same as "%i", but with escaping undone.

THis means that systemd will do unescaping which in this case means that instead of /etc/sysconfig/tomcat@ntis-adapter systemd is looking at /etc/sysconfig/tomcat@ntis/adapter

So in short: Tomcat needs to replace %I with %i in their unit file.
