SolrCloud インストールをセットアップしようとしています。このガイドに従っています: http://wiki.apache.org/solr/SolrCloudTomcat
solr インスタンスのいずれかを参照すると、次のエラー メッセージが表示されます (予想どおり)。

Using the Solr Admin UI currently requires at least one SolrCore.
ただし、curl コマンドを含む最後のステップで、次のエラーが発生します。
curl 'http://mysolr1.com:8080/solr/admin/collections?action=CREATE&name=collection&numShards=4&replicationFactor=1'
