To expand on that answer, you have to wonder what ports are open in the server system's port-based firewall. I have to ask my systems team to open ports for everything I'm using, especially when I move from localhost to outside.
You should be able to "fake it out" if you set up your zookeeper configuration to use localhost ports. -----Original Message----- From: Scott Prentice [mailto:s...@leximation.com] Sent: Monday, January 29, 2018 3:13 PM To: solr-user@lucene.apache.org Subject: SolrCloud installation troubles... Using Solr 7.2.0 and Zookeeper 3.4.11 In an effort to move to a more robust Solr environment, I'm setting up a prototype system of 3 Solr servers and 3 Zookeeper servers. For now, this is all on one machine, but will eventually be 3 machines. This works fine on a Ubuntu 5.4.0-6 VM on my local system, but when I do the same setup on the company's network machine (a Red Hat 4.8.5-16 VM), I'm unable to create a collection. To keep things simple, I'm not using our custom schema yet, but just creating a collection through the Solr Admin UI using Collections > Add Collection, using the "_default" config set. On the Ubuntu system, I can create various collections .. 1 shard w/ 1 replication .. 2 shards w/ 3 replications .. 3 shards w/ 4 replications .. all seem alive and well. But when I do the same thing on the Red Hat system it fails. Through the UI, it'll first time out with this message .. Connection to Solr lost Then after a refresh, the collection appears to have been partially created, but it's in the "Gone" state, and after some time, is deleted by an apparent cleanup process. If I try to create one through the command line .. ./bin/solr create -c test99 -n _default -s 2 -rf 2 I get this response .. ERROR: Failed to create collection 'test99' due to: {10.6.208.31:8984_solr=org.apache.solr.client.solrj.SolrServerException:IOException occured when talking to server at: http://10.6.208.31:8984/solr, 10.6.208.31:8985_solr=org.apache.solr.client.solrj.SolrServerException:IOException occured when talking to server at: http://10.6.208.31:8985/solr, 10.6.208.31:8983_solr=org.apache.solr.client.solrj.SolrServerException:IOException occured when talking to server at: http://10.6.208.31:8983/solr} I've seen other reports of errors like this but no solutions that seem to apply to my situation. Any thoughts? Thanks! ...scott
