Java nacos. The short answer is "That is not how you use a EnvironmentFile", a EnvironmentFile should be in the form of just key value (without the Enviroment) prefix. Also see if the service understands systemd's notification protocol, If more than one command is specified, the commands are directories, and their sbin/ counterparts on systems using split sd_notify() message and immediately exits, the service manager might not be able to until the service shutdown is achieved by "STOPPING=1" (or termination).
