卡桑德拉在Centos上表现不佳

Question

我正在使用Centos（CentOS Linux版本7.3.1611），并尝试使用Cassandra（3.0.9）。安装非常容易遵循，到目前为止效果很好。但是，当我（使用systemctl start cassandra）启动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.

我决定使用重新启动服务，systemctl restart cassandra但停止过程存在问题：

[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)
   Active: active (exited) since Wed 2017-05-03 12:15:50 CEST; 32s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 9478 ExecStop=/etc/rc.d/init.d/cassandra stop (code=exited, status=1/FAILURE)
  Process: 9508 ExecStart=/etc/rc.d/init.d/cassandra start (code=exited, status=0/SUCCESS)

May 03 12:15:49 localhost.localdomain systemd[1]: cassandra.service: control process exited, code=exited status=1
May 03 12:15:49 localhost.localdomain systemd[1]: Unit cassandra.service entered failed state.
May 03 12:15:49 localhost.localdomain systemd[1]: cassandra.service failed.
May 03 12:15:49 localhost.localdomain systemd[1]: Starting SYSV: Starts and stops Cassandra...
May 03 12:15:49 localhost.localdomain su[9515]: (to cassandra) root on none
May 03 12:15:50 localhost.localdomain cassandra[9508]: Starting Cassandra: OK
May 03 12:15:50 localhost.localdomain systemd[1]: Started SYSV: Starts and stops Cassandra.

您有解决这个问题的想法吗？谢谢 ：）

祝你今天愉快。
