Hi Christopher, Many thanks for your answer, well, I'm pretty comfortable with systemd myself as I rely on it for my Fedora box for a long time ago, but on this particular topic regarding tomcat, I don't really understand the purpose of this special sentence. As you pointed it, for me too usually caps names == env variables but as on the tomcat-sysd script it's simply called without futher sources I'm not quite sure for now.
Well, lets see if another *NIX Admin already had started multi-instances tomcat on systemd distributions :D Another way would be to completly duplicate the tomcat directory and service unit and start both at runtime but... doesn't seems too shiny for a new server :D 2014-12-10 16:27 GMT+01:00 Christopher Schultz <ch...@christopherschultz.net >: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > Billy, > > On 12/10/14 9:57 AM, Billy Bones wrote: > > Hi guys, > > > > I'm currently preparing a migration of our Operating System which > > handle our current tomcat installation from an OLD Linux using init > > scripts to a CentOS7 release using sytemd. > > Hrm.
