Solr learning Summary (2) installation and configuration of Solr, solr Summary

Next, I will summarize the installation and configuration of Solr.

 

　　1. Prepare

1. install java 8 and tomcat 9. The installation of java and tomcat is not repeated here. Note that these two versions are compatible. It seems that Java 8 does not support Tomcat 7 or earlier versions.

2. Download The solr installation package. The latest version is 5.3.1.

: Http://www.apache.org/dyn/closer.lua/lucene/solr/5.3.1

 

　　2. Installation

1. decompress the solr package, and copy the webapp folder under the solr-5.3.1 \ server \ solr-webap folder to the Tomcat \ webapps \ directory, and change it to solr

 

2. Copy all the jar files in the solr-5.3.0 \ server \ lib \ ext in the solr compressed package to the Tomcat \ webapps \ solr \ WEB-INF \ lib directory

 

3. Copy the solr-5.3.0/server/resources/log4j. properties in the solr package to the Tomcat \ webapps \ solr \ WEB-INF \ lib directory

 

4. Copy the solr-5.3.0/server/solr directory in the solr package to the Directory D: \ solr_home

5. Open web. xml under Tomcat/webapps/solr/WEB-INF and add the following configuration content (the content is commented out in the Initial State ):

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

Change the content in <env-entry-value> to your solrhome path. Here is D:/solr_home.

This configuration mainly establishes the relationship between tomcat and solr. It enables tomcat to find the solr directory you configured.

 

6. Restart tomcat and enter http: // localhost: 8080/solr in the browser to display the Solr management interface.

 

Note: At the beginning, I was unable to access the http: // localhost: 8080/solr/page. The following exception occurs:

Solution: copy the jar package in the dist folder decompressed by solr and the jar package under contrib \ velocity \ lib to the Tomcat \ webapps \ solr \ WEB-INF \ lib directory and then create the lib directory..

 

7. configure collection. In the D: \ solr_home directory, create a directory named mycore1 and copy all files under D: \ solr_home \ configsets \ basic_configs \ conf to D: \ solr_home \ mycore1 \ conf

 

8. In the D: \ solr_home directory, create the file core. properties and edit the file.

name= mycore1

9. Visit the http: // localhost: 8080/solr page. Check the core Admin and 'mycore1 '.

 

Here solr is basically installed successfully.
