Eu tenho o JIRA 7.5.2 instalado em um servidor do CentOS 7.4 e notei que há quatro duplicatas do serviço do JIRA Systemd:
[root@server ~]# systemctl list-units | grep jira
jira.service loaded active exited (null)
● jira1.service loaded failed failed (null)
jira2.service loaded active exited (null)
jira3.service loaded active running (null)
jira4.service loaded active exited (null)
Alguns estão ativos, outros não:
[root@server ~]# for svc in jira jira1 jira2 jira3 jira4; do systemctl status $svc; done
● jira.service - (null)
Loaded: loaded (/etc/rc.d/init.d/jira; bad; vendor preset: disabled)
Active: active (exited) since Tue 2018-10-02 08:35:37 CEST; 4h 59min ago
Docs: man:systemd-sysv-generator(8)
Process: 1155 ExecStart=/etc/rc.d/init.d/jira start (code=exited, status=0/SUCCESS)
● jira1.service - (null)

Eles estão todos desativados na inicialização.
Outro servidor JIRA que eu listei dois serviços duplicados.
Por que isso? Isto pode estar relacionado a this issue , embora exista apenas um processo Java em execução para o JIRA e seja de propriedade do usuário jira , como deveria.
