Solrcloud single-Machine Multi-node deployment (zookeeper3.4.6+solr4.10.4+tomcat7.0.61)

This scenario is to deploy multiple SOLR nodes on a single Linux host, ultimately achieving the solrcloud effect. Show the effect of the next Solrcloud standalone deployment first:

Two collection have been created on the Solrcloud.

Now let's talk about this deployment process:

Start by creating a Solrcloud directory that holds all the relevant software and configurations for Solrcloud.

1. Download and install Zookeeper

A multi-node deployment zookeeper is arguably required, and because of this simple work, it is possible to search for deployments from elsewhere on the network. This time using a single node zookeeper, the test environment is sufficient. After downloading the decompression zookeeper, go to the Zookeeper directory and execute the following command:

./bin/zkserver.sh Start

All zookeeper logs will be stored in./bin/zookeeper.out

2. Download Configuration solr-4.10.4 and tomcat7.0.61

After the decompression is complete:

Unzip the Solr-4.10.4/example/webapps/solr.war into the TOMCAT/WEBAPPS/SOLR directory

Unzip solr-4. 4./example/webapps/solr.war TOMCAT/WEBAPPS/SOLR

Copy the log4j configuration file and the jar package to Tomcat

CP solr-4. 4/example/lib/ext/*  tomcat/webapps/solr/web-inf/lib/

mkdir -P tomcat/webapps/solr/web-inf/classes/

CP solr-4.10. 4/example/resources/log4j.properties tomcat/webapps/solr/web-inf/classes

Upload the configuration file to zookeeper for cluster sharing configuration: Mainly the two files of Solrconfig.xml and Schema.xml.

The upload requires the Zookeeper toolkit that comes with SOLR to copy the tools into your own tool files.

CP -R  solrcloud/tomcat/webapps/solr/web-inf/lib/*  solrcloud/solr-lib

What we need to use is actually the Org.apache.solr.cloud.ZkCLI class.

Save the configuration files that need to be uploaded to the Solrcloud directory separately

CP -R solrcloud/solr-4.10. 4/example/solr/collection1/conf/*  solrcloud/config-files

Upload these configuration files to zookeeper

Java-classpath solrcloud/solr-lib/*  org.apache.solr.cloud.zkcli-cmd upconfig-zkhost 172.20.5.161:2181-confdir solrcloud/config-files/-confname solrconf

You can use Zookeeper's own client to view the data on the zookeeper

Zookeeper-3.4.6/bin/zkcli. SH 172.20. 5.161:2181

You can see that the SOLR cluster configuration data already exists

Associating the solrconf configuration file on zookeeper to the collection directory of Zookeeper

Java-classpath solrcloud/solr-lib/*  org.apache.solr.cloud.zkcli-cmd linkconfig-collection Mycollection-confname solrconf-zkhost 172.20.5.161:2181

The above steps have already deployed the configuration file

Next, you need to configure SOLR in Tomcat:

Create the Index1 directory under the Solrcloud directory as the index store. Create the Solr.xml file under the Index1 directory as the configuration for node 1. The contents of Solrcloud/index1/solr.xml are as follows:

<?XML version= "1.0" encoding= "UTF-8"?><SOLRPersistent= "true">  <coresHost= "172.20.5.161"AdminPath= "/admin/cores"Zkclienttimeout= "${zkclienttimeout:15000}"Hostport= "8080"Hostcontext= "${HOSTCONTEXT:SOLR}"></SOLR>

* The Hostport need to match Tomcat's external port address

Write the location of this file to the SOLR application of Tomcat.

Locate the env-entry tag in the Tomcat/webapps/solr/web-inf/web.xml file, enable it, and configure the following:

<!--<env-entry> <env-entry-name>solr/home</env-entry-name> <env-entry-value>/put/y Our/solr/home/here</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </en V-entry> -    <Env-entry>       <Env-entry-name>Solr/home</Env-entry-name>       <Env-entry-value>/home/clare/soft/solr/index1</Env-entry-value>       <Env-entry-type>Java.lang.String</Env-entry-type>    </Env-entry>

Replace the env-entry-value with your index1 directory.

Now ready to run, before running the tomcat boot parameter configuration, tomcat/bin/catalina.sh:

* Note is the first line of the script, not the last line

#!/bin/shexport java_opts="-dzkhost=172.20.5.161:2181"

The first node is configured so that it waits for a start.

===============================

Next, configure the second and third nodes:

Copy the Tomcat directory two copies to the current directory, named Tomcat-2 and tomcat-3

Copy the Index1 directory two copies to the current directory, named Index2 and Index3

So down, your directory should be as follows

First modify the Tomcat2/conf/server.xml file

The part that needs to be modified is the number +1 that will all port, making it inconsistent with the first node of Tomcat. The third node is similarly modified.

Then modify the Tomcat2/webapps/solr/web-inf/web.xml

Replace the value of Env-entry-value with the path to Index2

Finally, modify the Solr.xml file in Index2

Change the hostport here to Tomcat2 in the Conf/server.xml file in the same connector port

<port= "8081"  protocol= "http/1.1"               connectiontimeout  = "20000"               redirectport= "8444"/>

Start starting three nodes:

Execute the bin/catalina.sh start command under each Tomcat directory.

Then you can see the control panel by entering the machine IP:PORT/SOLR in the browser.

When there is no data in the cloud directory, you need to create a collection

Enter the Create command in the address bar in the browser to know that the index was created successfully:

Http://172.20.5.161:8080/solr/admin/collections?action=CREATE&name=secondindex&numshards =3&replicationfactor=1

You can then see the newly created index in the control Panel:

The next step is to pass the data to Solrcloud:

Cut to Directory/solr-4.10.4/example/exampledocs, execute the following directives, and upload some example documents to Solrcloud to create an index

Java-durl=http://172.20.5.161:8080/solr/secondindex/update-jar post.jar./*

Then perform the search test in the control Panel:

In this way the whole set of Solrcloud is basically built successfully.

Try the Java SDK again:

Wrote a Solrcloudhelper.java to test:

Execute Adddoc () First,

Then execute Docsearch ():

At this point, the Solrcloud test ends, and the operating principle will be served.
