错误如下

[[email protected] conf]# curl "http://192.168.1.235:8983/solr/admin/collections
?action=CREATE&name=tagCollectionHDFS&numShards=3&replicationFactor=3&maxShardsPerNode=3&collection.configName=tagCollectionHDFS"

< /lst>
<lst name="failure">

　内存不够了

修改solr.in.sh（分配的内存看节点情况）

solr-5.5.3/bin/solr.in.sh
SOLR_HEAP="512m"
改为：
SOLR_HEAP="8g"

重启即可。
