Build solrCloud--pseudo-distributed IP address: 192.168.25.154
1. At least three zookeeper nodes are required
2. Four tomcat nodes are required
Schematic:
Build a zookeeper cluster
Step 1: You need to install the jdk environment.
Step 2: Upload the compressed package of zookeeper to the server.
Step 3: Unzip.
Step 4: Copy zookeeper three times.
[root @localhost ~]# mkdir /usr/local/solr-cloud
[root @localhost ~]# cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper01
[root @localhost ~]# cp - r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper02
[root @localhost ~]# cp -r zookeeper-3.4.6 /usr/local/solr-cloud/zookeeper03
Step 5: In each zookeeper directory Create a data directory under.
Step 6: Create a myid file in the data directory, the file name is called "myid". The content is the id of each instance. eg 1, 2, 3
[root @localhost data]# echo 1 >> myid (or use vim)
Step 7: Modify the configuration file. Rename the zoo_sample.cfg file in the conf directory to zoo.cfg
Step 8: Start each zookeeper instance.
Start bin/zkServer.sh start
Check the status of zookeeper:
bin/zkServer.sh status
Note: After all zookeepers are started, the node status will not be displayed until the leader is elected
The construction of the stand-alone version of solr
Solr is developed in java.
jdk needs to be installed.
Installation environment Linux.
Tomcat needs to be installed.
step:
Step 1: Upload the solr compressed package to the Linux system
Step 2: Unzip solr.
contrib:solr extension package
docs: solr documentation
dist: destination file save directory
Example: Solr example
Step 3: Install Tomcat and unzip it.
Step 4: Deploy solr to Tomcat. Copy the solr.war in the dist directory to the
webAPP : Unzip the war package. Start Tomcat and extract it. Copy tomcat to the /usr/local/solr directory
Step 6: Add all the jar packages in the /root/solr-4.10.3/example/lib/ext directory to the solr project.
[root@localhost ext]# pwd
/root/solr-4.10.3/example/lib/ext
[root@localhost ext]# cp * /usr/local/solr/tomcat/webapps/solr/WEB-INF/lib/
Step 7: Create a solrhome. The /example/solr directory is a solrhome. Copy this directory to
/usr/local/solr/solrhome
[root@localhost example]# pwd
/root/solr-4.10.3/example
[root@localhost example]# cp -r solr /usr/local/solr/solrhome
Step 8: Associate solr and solrhome. The web.xml file of the solr project needs to be modified.
Step 9: Start Tomcat
http://192.168.25.154:8080/solr/
Build a Solr cluster
Step 1: Create four tomcat instances. Each tomcat runs on a different port. 8180 , 8280, 8380, 8480 The
second step: deploy the war package of solr. Copy the stand-alone version of the solr project to the tomcat in the cluster.
Step 3: Create a corresponding solrhome for each solr instance. Use the stand-alone version of solrhome to make four copies.
Step 4: You need to modify the web.xml file of solr. Associate solrhome.
Step 5: Configure solrCloud related configuration. There is a solr.xml under each solrhome, and configure the ip and port number in it.
Step 6: Let zookeeper manage the configuration files uniformly. You need to upload the solrhome/collection1/conf directory to zookeeper. Upload any configuration file in solrhome.
Upload the configuration file using the tool: /root/solr-4.10.3/example/scripts/cloud-scripts/zkcli.sh
| ./zkcli.sh -zkhost 192.168.25.154:2181,192.168.25.154:2182,192.168.25.154:2183 -cmd upconfig -confdir /usr/local/solr-cloud/solrhome01/collection1/conf -confname myconf |
View the configuration file on zookeeper:
Use the bin/zkCli.sh command in the zookeeper directory to view the configuration file on zookeeper:
[root@localhost bin]# ./zkCli.sh
[zk: localhost:2181(CONNECTED) 0] ls /
[configs, zookeeper]
[zk: localhost:2181(CONNECTED) 1] ls /configs
[myconf]
[zk: localhost:2181(CONNECTED) 2] ls /configs/myconf
[admin-extra.menu-top.html, currency.xml, protwords.txt, mapping-FoldToASCII.txt, _schema_analysis_synonyms_english.json, _rest_managed.json, solrconfig.xml, _schema_analysis_stopwords_english.json, stopwords.txt, lang, spellings.txt, mapping-ISOLatin1Accent.txt, admin-extra.html, xslt, synonyms.txt, scripts.conf, update-script.js, velocity, elevate.xml, admin-extra.menu-bottom.html, clustering, schema.xml]
[zk: localhost:2181(CONNECTED) 3]
退出：
[zk: localhost:2181(CONNECTED) 3] quit
Use the following command to connect to the specified zookeeper service:
./zkCli.sh -server 192.168.25.154:2183
Step 7: Modify the catalina.sh file in the tomcat/bin directory to associate solr and zookeeper.
Add this configuration to the configuration file:
JAVA_OPTS="-DzkHost=192.168.25.154:2181,192.168.25.154:2182,192.168.25.154:2183"
Step 8: Start each tomcat instance. To wrap the zookeeper cluster is the startup state.
Step 9: Access the cluster
Step 10: Create a new Collection for fragmentation processing.
http://192.168.25.154:8180/solr/admin/collectionsaction=CREATE&name=collection2&numShards=2&replicationFactor=2
Step 11: Delete unused Collections.
http://192.168.25.154:8180/solr/admin/collections?action=DELETE&name=collection1
The above are the steps to build SolrCloud, please correct them!
