我正在尝试使用DataStax Enterprise在单个节点上设置cassandra（这仅适用于非生产服务器上的DataStax Enterprise实验性使用）。我使用的是基于rhel的amazon image，我使用了以下说明来安装DataStax Enterprise：http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/install/installRHELdse.html
安装成功通过，然后我尝试按照以下说明启动DSE：http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/startStop/refDseServ.html（我只需要cassandra，因此我使用默认选项，其他服务被禁用）HADOOP_ENABLED=0 SOLR_ENABLED=0 SPARK_ENABLED=0
启动dse：

sudo service dse start
Starting DSE daemon : dse
DSE daemon starting with just Cassandra enabled (edit /etc/default/dse to enable)

检查netstats输出：

netstat -nltp
(No info could be read for "-p": geteuid()=500 but you should be root.)
Active Internet connections (only servers)

当检查cassandra日志时，没有错误：

Cassandra配置：/etc/dse/cassandra/cassandra.yaml具有以下重要属性：

seeds: "<AWS_PUBLIC_DNS>"
listen_address: <AWS_PUBLIC_DNS>
rpc_address: <AWS_PUBLIC_DNS>
endpoint_snitch: com.datastax.bdp.snitch.DseDelegateSnitch

Thanks in advance
