OK, the whole general order is that we do the stand-alone stage first.
Complete the stand-alone and then through copy and the corresponding zookeeper configuration to take care of the cluster.
This article is first used to introduce a single machine.

Single Stage
Place the file in the/USR/LOCAL/SOLR.

CD/USR/LOCAL/SOLR
wget https://mirrors.tuna.tsinghua.edu.cn/apache/lucene/solr/6.3.0/solr-6.3.0.tgz
tar -ZXVF solr-6.3.0.tgz

The corresponding project file after decompression can be placed in Tomcat and renamed.

CD Solr-6.3.0/server/solr-webapp
cp a cp-a webapp/usr/local/testtomcat/webapps
mv WebApp SOLR

Then copy the required package environment into Tomcat.
1. Copy all the jar packages under solr-6.3.0/server/lib/ext/to the testtomcat/webapps/solr/web-inf/lib/directory.
2. Copy the Log4j.properties file under Solr-6.3.0/server/resources/to the testtomcat/webapps/solr/web-inf/directory
3. Copy the Solr-dataimporthandler-6.3.0.jar and Solr-dataimporthandler-extras-6.3.0.jar under Solr-6.3.0/dist to the testtomcat/ Under the webapps/solr/web-inf/lib/directory

cd/usr/local/solr/solr-6.3.0/server/lib/ext/
CP *.jar/usr/local/testtomcat/webapps/solr/web-inf

cp/usr/ Local/solr/solr-6.3.0/server/resources/log4j.properties/usr/local/testtomcat/webapps/solr/web-inf

cp/usr/ Local/solr/solr-6.3.0/server/resources/log4j.properties/usr/local/testtomcat/webapps/solr/web-inf

cp/usr/ local/solr/solr-6.3.0/dist/solr-dataimporthandler-*/usr/local/testtomcat/webapps/solr/web-inf/lib
