Info

This section describes how to run a two-node SolrCloud cluster with no initial collections and a single-node external ZooKeeper. The commands below assume you have already created the keystore described above. Configure ZooKeeper ZooKeeper does not support encrypted communication with clients like Solr. There are several related JIRA tickets where SSL support is being planned/worked on: ZOOKEEPER-235; ZOOKEEPER-236; ZO OKEEPER-733; and ZOOKEEPER-1000. Before you start any SolrCloud nodes, you must configure your solr cluster properties in ZooKeeper, so that Solr nodes know to communicate via SSL. This section assumes you have created and started a single-node external ZooKeeper on port 2181 on localhost - see Setting Up an External ZooKeeper Ensemble The urlScheme cluster-wide property needs to be set to https before any Solr node starts up. The example below uses the zkcli tool that comes with the binary Solr distribution to do this: *nix command server/scripts/cloud-scripts/zkcli.sh -zkhost localhost:2181 -cmd clusterprop -name urlScheme -val https Windows command server\scripts\cloud-scripts\zkcli.bat -zkhost localhost:2181 -cmd clusterprop -name urlScheme -val https If you have set up your ZooKeeper cluster to use a chroot for Solr, make sure you use the correct zkhost string with zkcli, e.g. -zkhost localhost:2181/solr. Run SolrCloud with SSL Create Solr home directories for two nodes Create two copies of the server/solr/ directory which will serve as the Solr home directories for each of your two SolrCloud nodes: *nix commands mkdir cloud cp -r server/solr cloud/node1 cp -r server/solr cloud/node2 Windows commands mkdir cloud xcopy /E server\solr cloud\node1\ xcopy /E server\solr cloud\node2\ Start the first Solr node Next, start the first Solr node on port 8984. Be sure to stop the standalone server first if you started it when Apache Solr Reference Guide 6.0 528
working through the previous section on this page. *nix command bin/solr -cloud -s cloud/node1 -z localhost:2181 -p 8984 Windows command bin\solr.cmd -cloud -s cloud\node1 -z localhost:2181 -p 8984 Notice the use of the -s option to set the location of the Solr home directory for node1. If you created your SSL key without all DNS names/IP addresses on which Solr nodes will run, you can tell Solr to skip hostname verification for inter-Solr-node communications by setting the solr.ssl.checkPeerName sys tem property to false: *nix command bin/solr -cloud -s cloud/node1 -z localhost:2181 -p 8984 -Dsolr.ssl.checkPeerName=false Windows command bin\solr.cmd -cloud -s cloud\node1 -z localhost:2181 -p 8984 -Dsolr.ssl.checkPeerName=false Start the second Solr node Finally, start the second Solr node on port 7574 - again, to skip hostname verification, add -Dsolr.ssl.check PeerName=false; *nix command bin/solr -cloud -s cloud/node2 -z localhost:2181 -p 7574 Windows command bin\solr.cmd -cloud -s cloud\node2 -z localhost:2181 -p 7574 Example Client Actions cURL on OS X Mavericks (10.9) has degraded SSL support. For more information and workarounds to allow 1-way SSL, see http://curl.haxx.se/mail/archive-2013-10/0036.html . cURL on OS X Yosemite (10.10) is improved - 2-way SSL is possible - see http://curl.haxx.se/mail/archive-2014-10/0053.html . The cURL commands in the following sections will not work with the system curl on OS X Yosemite (10.10). Instead, the certificate supplied with the -E param must be in PKCS12 format, and the file supplied with the --cacert param must contain only the CA certificate, and no key (see above for instructions on creating this file): Apache Solr Reference Guide 6.0 529
