我正在尝试设置 SolrCloud 安装，并且我遵循了本指南：http ://wiki.apache.org/solr/SolrCloudTomcat

浏览到任何 solr 实例时，我都会收到此错误消息（如预期的那样）：

There are no SolrCores running.
Using the Solr Admin UI currently requires at least one SolrCore.

但是，在涉及 curl 命令的最后一步，我收到以下错误：

curl 'http://mysolr1.com:8080/solr/admin/collections?action=CREATE&name=collection&numShards=4&replicationFactor=1'

有任何想法吗？

似乎 Solr 无法通信或 Solr 没有从 ZooKeeper 获得预期的响应。

根据 Solr 4.2.1源代码：

Line 149 # QueueEvent event = coreContainer.getZkController()
.getOverseerCollectionQueue()
.offer(ZkStateReader.toJSON(m), DEFAULT_ZK_TIMEOUT);

那么您能否验证一下：

连接到 ZooKeeper 并验证 Solr 配置是否存在（此参考可能会有所帮助）

让我知道结果！
