solr tutorial fails to create collection

问题:

I'm trying to run the solr 6.6.0 tutorial and after running:

bin/solr start -e cloud -noprompt

it starts solr on ports 8983 and 7574 but fails to create the getting started collection with the following error:

ERROR: Failed to create collection 'gettingstarted' due to: {10.1.20.105:7574_solr=org.apache.solr.client.solrj.SolrServerException:IOException occured when talking to server at: http://10.1.20.105:7574/solr}


ERROR: Failed to create collection using command: [-name, gettingstarted, -shards, 2, -replicationFactor, 2, -confname, gettingstarted, -confdir, data_driven_schema_configs, -configsetsDir, /Users/rcarey/solr-6.6.0/server/solr/configsets, -solrUrl, http://localhost:8983/solr]

It looks like its trying to create each replica on a different ip, rather than a different port on the same ip. 10.1.20.105 is not the IP that the 8983 replica is using. I'm not sure if theres something additional I need to configure for this so that it uses the one IP for both. I have the host set to localhost.

The Solr Admin is available on both http://localhost:8983/solr and http://localhost:7574/solr

I get the following in the log:

24/08/2017, 11:38:36 ERROR null OverseerCollectionMessageHandler Cleaning up collection [gettingstarted].

24/08/2017, 11:39:06 ERROR null CollectionsHandler Timed out waiting for new collection's replicas to become ACTIVE with timeout=30

Help me to fix this.

回答1:

I had the same issue. In bin/solr.in.sh, I uncommented and set the following:

SOLR_HOST="localhost"

Then things worked because solr communicated with the server via "localhost" instead of an IP, which had a timeout. Fixing the error:

SolrServerException:IOException occured when talking to server at: http://YOUR_IP/solr
