| solr 6.1 and zookeeper | |
| 1. install solr via puppet | |
| 2. stop solr | |
| 3. install zookeeper | |
| cd /cul/share | |
| sudo wget http://apache.claz.org/zookeeper/stable/ | |
| zookeeper-3.4.8.tar.gz | |
| sudo tar xvzf zookeeper-3.4.8.tar.gz ; sudo ln -s zookeeper-3.4.8 zookeeper | |
| 4. configure zookeeper (zoo.cfg, myid) | |
| create /cul/share/zookeeper/conf/zoo.cfg: | |
| ############################# | |
| tickTime=2000 | |
| initLimit=10 | |
| syncLimit=5 | |
| dataDir=/cul/share/zookeeper/tmp | |
| clientPort=2181 | |
| server.1=aws-110-194.internal.library.cornell.edu:2888:3888 | |
| server.2=aws-110-195.internal.library.cornell.edu:2888:3888 | |
| server.3=aws-110-196.internal.library.cornell.edu:2888:3888 | |
| ############################# | |
| Create /cul/share/zookeeper/tmp/myid | |
| - contents should simply the server.X number from the config, i.e., the myid content for server "aws-110-194.internal.library.cornell.edu" should be "1" | |
| 5. start zookeeper | |
| sudo /cul/share/zookeeper/bin/zkServer.sh start | |
| test/check node status: | |
| echo stat | nc localhost 2181 | grep Mode | |
| results should be "Mode: follower" or "Mode: leader" | |
| 6. configure solr (/etc/default, solr.xml) | |
| Change the following lines in /cul/data/solr/data/solr.xml: | |
| <str name="host">${host:}</str> | |
| to: | |
| <str name="host">aws-110-194.internal.library.cornell.edu</str> | |
| (where "aws-110-194.internal.library.cornell.edu" is the server's hostname. IP address can be used here as well) | |
| Add/change the following lines in /etc/default/solr.in.sh: | |
| SOLR_PORT="8983" | |
| SOLR_MODE=solrcloud | |
| ZK_HOST=aws-110-194.internal.library.cornell.edu:2181,aws-110-195.internal.library.cornell.edu:2181,aws-110-196.internal.library.cornell.edu:2181 | |
| 7. start solr | |
| 8. upload solr config to zookeeper | |
| sh /cul/app/solr/solr-6.1.0/server/scripts/cloud-scripts/zkcli.sh -zkhost aws-110-194.internal.library.cornell.edu:2181,aws-110-195.internal.library.cornell.edu:2181,aws-110-196.internal.library.cornell.edu:2181 -cmd upconfig -confname data_driven -confdir /cul/app/solr/solr/server/solr/configsets/data_driven_schema_configs/conf | |
| 9. Verify the config made it to zookeeper | |
| /cul/share/zookeeper/bin/zkCli.sh | |
| [zk: localhost:2181(CONNECTED) 0] ls /configs | |
| [data_driven] | |
| 10. Create a collection | |
| On a single node, hit the following URL: | |
| http://aws-110-195.internal.library.cornell.edu:8983/solr/admin/collections?action=CREATE&name=test_solrcloud&numShards=2&replicationFactor=2&maxShardsPerNode=2&collection.configName=data_driven | |
| 11. Verify by checking the cloud config | |
| http://aws-110-195.internal.library.cornell.edu:8983/solr/#/~cloud | |
