我已经按照此链接安装了 cassandra https://linuxize.com/post/how-to-install-apache-cassandra-on-centos-7/ 。 但是当我安装后启动cassandra服务时，它显示以下错误:
Job for cassandra.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status cassandra.service" and "journalctl -xe" for details.
systemctl status cassandra 有以下输出:

我无法弄清楚为什么 cassandra 服务没有启动。
最佳答案
CassandraDaemon.java:759 - 端口已在使用中:7199 java.net.BindException:地址已在使用中(绑定(bind)失败)
端口 7199 已被使用。使用 netstat -tulpn 您可以显示所有正在运行的应用程序的列表。 Cassandra 需要能够绑定(bind)此端口。
