Install and deploy SOLR under Linux

First, installation Preparation

Operating system: CentOS 6.5

Tomcat version: apache-tomcat-7.0.54.tar.gz

SOLR version: Solr-4.9.0.tgz

Ii. Deployment Implementation

• Install Tomcat: slightly .....

• Then go to the Tomcat/bin folder, execute the./startup.sh startup script, and then access Tomcat's url:http://ip:8080 in the browser, such as deploying Tomcat successfully.

• Install SOLR: Solr-4.9.0.tgz compressed package Last to the Linux/opt directory, use the command line to extract the solr-4.9.0, and rename the folder to Solr, and then create the Solr folder as SOLR's deployment root directory, created in SOLR/ Usr/local/solr/solr-index directory that is stored as an index file:

  TAR-ZXVF solr-4.9.0.tgzmv solr-4.9.0 solrmkdir-p/USR/LOCAL/SOLRCD/USR/LOCAL/SOLR; mkdir solr-indexcp-r/opt/solr/example/solr/*     /USR/LOCAL/SOLR

  Copy all the contents under the/opt/solr/example/solr/folder to the Solr folder and enter/usr/local/solr/collection1/conf with a solrconfig.xml file and open:

  <lib dir= ". /.. /.. /contrib/extraction/lib "regex=". *\.jar "/>  <lib dir=". /.. /.. /dist/"regex=" Solr-cell-\d.*\.jar "/>   <lib dir=". /.. /.. /contrib/clustering/lib/"regex=". *\.jar "/>  <lib dir=". /.. /.. /dist/"regex=" Solr-clustering-\d.*\.jar "/>   <lib dir=". /.. /.. /contrib/langid/lib/"regex=". *\.jar "/>  <lib dir=". /.. /.. /dist/"regex=" Solr-langid-\d.*\.jar "/>   <lib dir=". /.. /.. /contrib/velocity/lib "regex=". *\.jar "/>  <lib dir=". /.. /.. /dist/"regex=" Solr-velocity-\d.*\.jar "/>

•  <datadir>${solr.data.dir:}</datadir> 

  Modified to:

   <!--<lib dir= ".. /.. /.. /contrib/extraction/lib "regex=". *\.jar "/> <lib dir=". /.. /.. /dist/"regex=" Solr-cell-\d.*\.jar "/> <lib dir=". /.. /.. /contrib/clustering/lib/"regex=". *\.jar "/> <lib dir=". /.. /.. /dist/"regex=" Solr-clustering-\d.*\.jar "/> <lib dir=". /.. /.. /contrib/langid/lib/"regex=". *\.jar "/> <lib dir=". /.. /.. /dist/"regex=" Solr-langid-\d.*\.jar "/> <lib dir=". /.. /.. /contrib/velocity/lib "regex=". *\.jar "/> <lib dir=". /.. /.. /dist/"regex=" Solr-velocity-\d.*\.jar "/>--> 

   <datadir >${solr.data.dir:/usr/local/solr/solr-index}</datadir> 

  Enters the dist directory in the/OPT/SOLR catalog, There is a Solr-4.9.0.war bag, copied to your tomcat under the WebApps directory (~/tomcat7/webapps), and renamed to Solr.war, launched Tomcat will automatically unzip the deployment of Solr.war package, and extracted to the SOLR directory under the directory, this directory is a standard Web project directory.

• To enter ~/tomcat7/webapps/solr/web-inf, modify the Web. xml file as follows:

  <env-entry>       <env-entry-name>solr/home</env-entry-name>       <env-entry-value>/home/ Hadoop2/solrhome</env-entry-value>       <env-entry-type>java.lang.String</env-entry-type>    </env-entry>

  You need to copy some jar packages and log4j configuration files: Copy all jars from ~/solr/example/lib/ext and copy ~/solr/example/resources/log4j.properties to ~/tomcat7/ Under Lib.

• Start the SOLR server: After completing the above configuration, reboot the Tomcat server and then access the URL:HTTP://IP:8080/SOLR of the SOLR server, if you see the following interface, the deployment is successful:
