Install SOLR under Tomcat

SOLR version: 4.10.1

Tomcat version: 7.0.23

JDK version: 1.7.0 _ 01

Note: SOLR explicitly requires JDK 1.7 or later.

Install Tomcat and JDK.

Download SOLR: http://lucene.apache.org/solr/downloads.html

1. Decompress the solr-4.10.1 to: solr-4.10.1 \ example \ webapps \ SOLR. war is deployed in Tomcat, that is, copy SOLR. war to E: \ Server \ apache-Tomcat-SOLR \ webapps (I changed my tomcat name to Apache-Tomcat-SOLR)
2. Start tomcat to decompress SOLR. War in webapps to generate the SOLR directory (an error will be reported first)
3. Create a folder to store SOLR configuration files such as E:/SOLR/home and copy all files from solr-4.10.0 \ example \ SOLR to this directory
4. Modify E:/SOLR/home/collection1/CONF/solrconfig. xml

    <dataDir>${solr.data.dir:}</dataDir>  

Is:

<dataDir>${solr.data.dir:E:/solr/home/collection1/data}</dataDir>  

 

5. copy the jar package under solr-4.10.1 \ example \ Lib \ ext to Apache-Tomcat-SOLR \ webapps \ SOLR \ WEB-INF \ Lib (because the sl4j package will be used, not in the original war)

 

6. modify \ webapps \ SOLR \ WEB-INF \ WEB. XML in

<!--      <env-entry>         <env-entry-name>solr/home</env-entry-name>         <env-entry-value>/put/your/solr/home/here</env-entry-value>         <env-entry-type>java.lang.String</env-entry-type>      </env-entry>     --> 

 

Change

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

7. Create the file classes folder under Apache-Tomcat-SOLR \ webapps \ SOLR \ WEB-INF,

And copy solr-4.10.1 \ example \ resources \ log4j. properties to: APACHE-Tomcat-SOLR \ webapps \ SOLR \ WEB-INF \ Classes

8. Add a startup log to warn that the jar package cannot be found.

Solrconfig. xml contains some jar package configuration items, such

 <lib dir="../../../contrib/extraction/lib" regex=".*\.jar" />  <lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />

You need to modify the path here, or

Do not create a new solr_home E:/SOLR/home; directly use the decompressed SOLR file to direct all SOLR \ home configurations to the decompressed file E: \ solr-4.10.1 \ example \ SOLR

 

Finally, start Tomcat and access http: // localhost: 8080/SOLR/

There was a problem that I had been delayed for a long time. When I started tomcat, the error filterstart was reported. I always thought it was a jar package conflict,

The result turns out that catalina_home is not configured. Generally, you can directly throw the war package you typed into Tomcat without configuring Tomcat environment variables,

I don't know if there is a configuration in SOLR that requires catalina_home. Add the catalina_home environment variable and start it successfully!
