How to Install Solr in Tomcat?

Question

I've put the file apache-solr-3.5.0.war in folder C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps.

A folder "apache-solr-3.5.0" is created automatically. And when I go to: http://localhost:8080/apache-solr-3.5.0/ .

I can see the message "Welcome to Solr!".

Now, when I do the exact same with the file solr-4.3.1.war in the folder C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps

A folder solr-4.3.1 is created automatically. But now when I go to:

http://localhost:8080/solr-4.3.1/ OR to http://localhost:8080/solr-4.3.1/admin.html

I see the error:

HTTP Status 404 - type Status report

Message: description The requested resource is not available.

Apache Tomcat/6.0.37

What am I missing?

Update:

This is shown in the Tomcat console window:

My unpacked Solr folder contains these folders:

css  
img  
js  
META-INF  
tpl  
WEB-INF  

Update

After adding this to my environment variables:

JAVA_OPTS = $JAVA_OPTS -Dsolr.solr.home=C:/Databases/solr-4.3.1/example/solr

I get these 2 errors after startup:

SEVERE: org.apache.solr.common.SolrException: Invalid luceneMatchVersion 'LUCENE_43', valid values are: [LUCENE_20, LUCENE_21, LUCENE_22, LUCENE_23, LUCENE_24,LUCENE_29, LUCENE_30, LUCENE_31, LUCENE_32, LUCENE_33, LUCENE_34,LUCENE_35, LUCENE_CURRENT] or a string in format 'V.V'

I'm now getting a "HTTP Status 503 - Server is shutting down" error.

I read something on this error here, but after adding my logging.properties.

Answer 1

Install Solr in Tomcat

Pre Requirements

1 – Machine with Windows OS (Windows 7,8,Xp.. ..etc)

2 – Java 6 or Above

3 - Solr 4.0.0 or Above

4 – Apache-tomcat 6 or Above.

Steps to get Solr up on Tomcat Server

1.Install Tomcat on your machine and make sure it is ready to start.(Check using localhost:8080)

2.Install Solr4.0 distribution package apache-solr-4.0.0.zip and unzip it in your local directory like C:\apache-solr-4.0.0.

3.Make a folder with name solr-home in your local machine like C:\solr_home.

4.Go back to the solr distribution package that you downloaded C:\apache-solr-4.0.0. Have a peek inside the Examples/solr ("C:\solr-4.4.0\example\solr") folder. Copy all those files into the C:\solr_home folder.(server shutting down exception will come)

5.Look into C:\solr-home\solr and you will see two folders with name collection1 and bin, copy these two folders a step up to C:\solr_home.(if lib not copy "severe error filterstart" Exception come)

6.Copy lib from C:\apache-solr-4.0.0\example\lib\ext SLF4J and log4j.jar file to Tomcat Lib folder C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib (https://wiki.apache.org/solr/SolrLogging#Using_the_example_logging_setup_in_containers_other_than_Jetty)

7.Copy apache-solr-4.0.war (rename to solr.war) from "C:\solr-4.4.0\dist" directory to webapps directory inside Tomcat.(C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps)

8.If tomact is already start then solr folder will create go to "C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\solr\WEB-INF\web.xml" edit web.xml uncomment entry and edit like following(Exception SolrCore 'collection1' is not available due to init failure)

<env-entry>
   <env-entry-name>solr/home</env-entry-name>
   <env-entry-value>C:\solr_home\solr</env-entry-value>
   <env-entry-type>java.lang.String</env-entry-type>
</env-entry>

9.Start Tomcat and check localhost:8080/solr dashBoard will come

Answer 2

It got solved for me by on a different forum, here are the steps I followed:

1. Extract solr431 package. In my case I did in "E:\solr-4.3.1\example\solr"
2. Now copied solr dir from extracted package (E:\solr-4.3.1\example\solr) into TOMCAT_HOME dir. In my case TOMCAT_HOME dir is pointed to E:\Apache\Tomcat 6.0.
3. I can refer now SOLR_HOME as " E:\Apache\Tomcat 6.0\solr" (please remember this)
4. Copy the solr.war file from extracted package to SOLR HOME dir i.e E:\Apache\Tomcat 6.0\solr. This is required to create the context. As I donot want to pass this as JAVA OPTS
5. Also copy solr.war file into TOMCAT_HOME\webapps for deployment purpose

6. If you start tomcat you will get errors as mentioned by Shawn. S0 you need to copy all the 5 jar files from solr extracted package ( E:\solr-4.3.1\example\lib\ext ) to TOMCAT_HOME\lib dir:

   1. jul-to-slf4j-1.6.6,
   2. jcl-over-slf4j-1.6.6,
   3. slf4j-log4j12-1.6.6,
   4. slf4j-api-1.6.6,
   5. log4j-1.2.16

7. Also copy the log4js.properties file from E:\solr-4.3.1\example\resources dir to TOMCAT_HOME\lib dir.

8. Now if you start the tomcat you wont having any problem.
