Solr6.0 pseudo-cluster build collection failed to create

Hello everyone, I set up a solr pseudo-cluster environment on my machine, and the startup was successful, but I encountered problems when creating it.

Create collection command:
solr-6.0.0-1/bin/solr create_collection -c search -d solr-6.0.0-1/solrhome/conf/files/ -shards 3 -replicationFactor 2

Error code:
Connecting to ZooKeeper at localhost: 2181,localhost:2182,localhost:2183 ...
Re-using existing configuration directory search

Creating new collection 'search' using command:
http://localhost:8984/solr/admin/collections?action=CREATE&name=search&numShards=3&replicationFactor= 2&maxShardsPerNode=2&collection.configName=search


ERROR: Failed to create collection 'search' due to: Could not fully create collection: search
Please help us to see what the problem might be, thank you.
