Info

zkHost No default The host address for ZooKeeper. Usually this is a comma-separated list of addresses to each node in your ZooKeeper ensemble. zkClientTimeout Defaults to 15000 The time a client is allowed to not talk to ZooKeeper before its session expires. zkRun and zkHost are set up using system properties. zkClientTimeout is set up in solr.xml by default, but can also be set using a system property. SolrCloud Core Parameters shardId Defaults to being automatically assigned based on numShards Allows you to specify the id used to group cores into shards. shardId can be configured in solr.xml for each core element as an attribute. Additional cloud related parameters are discussed in Solr Cores and solr.xml. Command Line Utilities Solr's Administration page (found by default at http://hostname:8983/solr/ ), provides a section with menu items for monitoring indexing and performance statistics, information about index distribution and replication, and information on all threads running in the JVM at the time. There is also a section where you can run queries, and an assistance area. In addition, SolrCloud provides its own administration page (found at http://localhost:8983/solr/#/~cloud), as well as a few tools available via a ZooKeeper Command Line Utility (CLI). The CLI scripts found in server/script s/cloud-scripts let you upload configuration information to ZooKeeper, in the same two ways that were shown in the examples in Parameter Reference. It also provides a few other commands that let you link collection sets to collections, make ZooKeeper paths or clear them, and download configurations from ZooKeeper to the local filesystem. Solr's zkcli.sh vs ZooKeeper's zkCli.sh The zkcli.sh provided by Solr is not the same as the zkCli.sh included in ZooKeeper distributions. ZooKeeper's zkCli.sh provides a completely general, application-agnostic shell for manipulating data in ZooKeeper. Solr's zkcli.sh – discussed in this section – is specific to Solr, and has command line arguments specific to dealing with Solr data in ZooKeeper. Using Solr's ZooKeeper CLI Both zkcli.sh (for Unix environments) and zkcli.bat (for Windows environments) support the following command line options: Short Parameter Usage Meaning -cmd CLI Command to be executed: bootstrap, upconfig, downconfig, linkconfi g, makepath, get, getfile, put, putfile, list, clear or clusterprop. This parameter is mandatory Apache Solr Reference Guide 6.0 600
-z -zkhost -c -collection -d -confdir ZooKeeper host address. This parameter is mandatory for all CLI commands. For linkconfig: name of the collection. For upconfig: a directory of configuration files. For downconfig: the destination of files pulled from Zookeeper -h -help Display help text. -n -confname -r -runzk -s -solrhome -name -val For upconfig, linkconfig, downconfig: name of the configuration set. Run ZooKeeper internally by passing the Solr run port; only for clusters on one machine. For bootstrap or when using -runzk: the mandatory solrhome location. For clusterprop: the mandatory cluster property name. For clusterprop: the cluster property value. If not specified, null will be used as value. The short form parameter options may be specified with a single dash (eg: -c mycollection). The long form parameter options may be specified using either a single dash (eg: -collection mycollection) or a double dash (eg: --collection mycollection) ZooKeeper CLI Examples Below are some examples of using the zkcli.sh CLI which assume you have already started the SolrCloud example ( bin/solr -e cloud -noprompt) If you are on Windows machine, simply replace zkcli.sh with zkcli.bat in these examples. Upload a configuration directory ./server/scripts/cloud-scripts/zkcli.sh -zkhost 127.0.0.1:9983 \ -cmd upconfig -confname my_new_config -confdir server/solr/configsets/basic_configs/conf Bootstrap ZooKeeper from existing SOLR_HOME ./server/scripts/cloud-scripts/zkcli.sh -zkhost 127.0.0.1:2181 \ -cmd bootstrap -solrhome /var/solr/data Bootstrap with chroot Using the boostrap command with a zookeeper chroot in the -zkhost parameter, e.g. -zkhost 127.0.0.1:2181/solr, will automatically create the chroot path before uploading the configs. Put arbitrary data into a new ZooKeeper file Apache Solr Reference Guide 6.0 601
