У меня есть Java-проект со встроенным Tomcat 8.5. Я добавил новую службу в sytemd, чтобы запускать ее как службу в CentOS 7.2. Когда я использую "systemctl start app.service" для запуска сервера, программа останавливается на
"Aug 16, 2018 5:54:13 PM org.apache.catalina.core.StandardEngine startInternal
INFO: Starting Servlet Engine: Apache Tomcat/8.5.32"
Я использовал команду "jstack", чтобы проверить процесс, и получил информацию ниже:

[Unit]
Description=testapp
After=network.target
[Service]
Type=forking
ExecStart=/test/app/startup.sh
[Install]
WantedBy=multi-user.target
Содержимое моего скрипта startup.sh:

Когда я запускаю свой сценарий "startup.sh", проблем нет. Когда я использую команду «systemctl», программа приостанавливается, но процесс продолжается.
Как мне справиться с этой проблемой. Есть ли разница между запущенным сценарием оболочки и командой "systemctl"?
