Question

我已经完成了datastax指令，用于启用solr（DSE搜索）并从下面的文档中逐行配置cassandra但solr仍然无法正常工作，我的意思是无法通过浏览器或curl到达http://localhost:8983。

datastax docs for enabling solr (DSE search)

我尝试使用solr重新加载cassandra（命令：sudo dse cassandra -s ）但是在运行命令后发生此异常：

Answer 1

看起来你没有停止已经运行的进程。你能检查一下你是否有另一个cassandra进程正在运行（在你的情况下是dse）吗？

Answer 2

此问题与DSE搜索中的搜索功能无关。 Cassandra想要出现但是有些东西与jmx端口7199绑定。

您可以使用＆＃39; netstat -a |找出绑定到该端口的内容grep 7199＆＃39;。但是，很可能您已经有一个现有的dse实例。

sudo pkill -f dse

将杀死dse进程。然后你可以尝试再次启动它。

在datastax中启用后，datastax solr不起作用
