我刚刚在全新的 CentOS 7 上安装了 Firebird，但是无法找到它systemctl：
[root@intranet-ii ~]# yum install firebird
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: centos.mirror.transip.nl
* epel: ams.edge.kernel.org
* extras: mirror.denit.net
* updates: mirror.ams1.nl.leaseweb.net
Package firebird-2.5.7.27050.0-1.el7.x86_64 already installed and latest version
Nothing to do
[root@intranet-ii ~]# systemctl start firebird-superserver
Failed to start firebird-superserver.service: Unit not found.
我找不到服务器应该驻留在何处，也没有在网上找到任何相关参考。
