如何在CoreOS上安装Cassandra？

我正在尝试在CoreOS虚拟机上安装Cassandra。为此，我在/ etc / systemd / system中创建了Cassandra.service文件

[Unit] Description=Cassandra After=docker.service Requires=docker.service

[Service] TimeoutStartSec=0 ExecStartPre=-/usr/bin/docker kill cassandra-db ExecStartPre=-/usr/bin/docker rm cassandra-db ExecStartPre=/usr/bin/docker pull cassandra ExecStart=/usr/bin/docker run --name cassandra-db -d Cassandra

[Install] WantedBy=multi-user.target 然后我启用并启动了该服务

sudo systemctl enable /etc/systemd/system/cassandra.service

sudo systemctl启动cassandra.service

但后来我得到了这个输出

docker0: port 1(veth8a5f0d2) entered blocking state docker0: port 1(veth8a5f0d2) entered disabled state device veth8a5f0d2 entered promiscuous mode IPv6: ADDRCOMF(NETDEV_UP): veth8a5f0d2: link is not ready eth0: renamed from vethc1e5ef2 IPv6: ADDRCOMF(NETDEV_CHANGE): veth8a5f0d2: link becomes ready docker0: port 1(veth8a5f0d2) entered blocking state docker0: port 1(veth8a5f0d2) entered forwarding state IPv6: ADDRCOMF(NETDEV_CHANGE): docker0: link becomes ready 并且提示永远不会再次出现，因此我不知道Cassandra数据库是否已启动以及如何访问它。

有任何想法吗？
