我正在开发 Centos(CentOS Linux 版本 7.3.1611)，并尝试使用 Cassandra(3.0.9)。安装很容易理解，到目前为止一切都很好。但是当我启动 Cassandra(使用 systemctl start cassandra )时，服务是:
“active (exited)”而不是“active (running)”。
[root@localhost ~]# systemctl status cassandra
● cassandra.service - SYSV: Starts and stops Cassandra
Loaded: loaded (/etc/rc.d/init.d/cassandra; bad; vendor preset: disabled)
Active: active (exited) since Wed 2017-05-03 12:06:54 CEST; 5s ago
Docs: man:systemd-sysv-generator(8)
Process: 9337 ExecStart=/etc/rc.d/init.d/cassandra start (code=exited, status=0/SUCCESS)
May 03 12:06:54 localhost.localdomain systemd[1]: Starting SYSV: Starts and stops Cassandra...
May 03 12:06:54 localhost.localdomain su[9344]: (to cassandra) root on none
May 03 12:06:54 localhost.localdomain cassandra[9337]: Starting Cassandra: OK
May 03 12:06:54 localhost.localdomain systemd[1]: Started SYSV: Starts and stops Cassandra.
我决定重新启动服务，使用
systemctl restart cassandra ，但是停止过程有问题:[root@localhost ~]# systemctl restart cassandra
[root@localhost ~]# systemctl status cassandra
● cassandra.service - SYSV: Starts and stops Cassandra
Loaded: loaded (/etc/rc.d/init.d/cassandra; bad; vendor preset: disabled)

你有解决这个问题的想法吗？谢谢 :)
祝你今天过得愉快。
