4, steps

4.1 by putty connection CentOS7, decompression solr and tomcat

# 确保solr-4.10.3.tgz、apache-tomcat-8.5.38.zip是在当前目录下
ls
# 解压solr-4.10.3.tgz
tar -xvf solr-4.10.3.tgz
# 解压apache-tomcat-8.5.38.zip
unzip apache-tomcat-8.5.38.zip
# 赋予tomcat中bin目录下文件的可执行权限
chmod 777 /rootapache-tomcat-8.5.38/bin/*
启动tomcat。注意：启动tomcat之前要先配置好jdk环境变量。
/root/rootapache-tomcat-8.5.38/bin/startup.sh

4.2 solr.war to copy the webapps tomcat

cp /root/solr-4.10.3/example/webapps/solr.war /root/apache-tomcat-8.5.38/webapps/

Wait a moment, war package will be unpacked.

4.3 Copy jar package

cp /root/solr-4.10.3/example/lib/ext/* /root/apache-tomcat-8.5.38/webapps/solr/WEB-INF/lib/

4.4 modify the package solr war web.xml

Edit /root/apache-tomcat-8.5.38/webapps/solr/WEB-INF/web.xml
found

<!--
    <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>    
 -->

To change it

    <env-entry>
       <env-entry-name>solr/home</env-entry-name>
       <env-entry-value>/root/solr-4.10.3/example/solr</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

Restart tomcat, and turn off the firewall [Note that the actual production environment will not turn off the firewall, here is a test, so simple and crude].
