Centos7安装Solr7.2.1

wget http://mirrors.hust.edu.cn/apache/lucene/solr/7.2.1/solr-7.2.1.tgz 
wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.0.50/bin/apache-tomcat-8.0.50.tar.gz[/code] 解压压缩包并放到/opt/目录下

tar -xvf solr-7.2.1.tgz

tar -xvf apache-tomcat-8.0.50.tar.gz
cp apache-tomcat-8.0.50 /opt/tomcat -rf

创建/opt/solr_home目录

mkdir /opt/solr_home

清空tomcat下没用的项目

rm -rf /opt/tomcat/webapps/*

复制需要的文件到webapps下

cp solr-7.2.1/server/solr-webapp/webapp /opt/tomcat/webapps/solr -rf

cp solr-7.2.1/server/lib/ext/* /opt/tomcat/webapps/solr/WEB-INF/lib/

cp solr-7.2.1/server/lib/metrics-*.jar /opt/tomcat/webapps/solr/WEB-INF/lib/

cp solr-7.2.1/dist/solr-dataimporthandler-* /opt/tomcat/webapps/solr/WEB-INF/lib/

创建classes文件件

mkdir /opt/tomcat/webapps/solr/WEB-INF/classes

复制log4j.properties到classes下

cp solr-7.2.1/server/resources/log4j.properties /opt/tomcat/webapps/solr/WEB-INF/classes/

修改web.xml

# vim /opt/tomcat/webapps/solr/WEB-INF/web.xml

<!--
<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>
-->

去掉注释并修改solr_home:
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/opt/solr_home</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>

<security-constraint>
<web-resource-collection>
<web-resource-name>Disable TRACE</web-resource-name>
<url-pattern>/</url-pattern>
<http-method>TRACE</http-method>
</web-resource-collection>
<auth-constraint/>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>Enable everything but TRACE</web-resource-name>
<url-pattern>/</url-pattern>
<http-method-omission>TRACE</http-method-omission>
</web-resource-collection>
</security-constraint>

加上注释:
<!--
<security-constraint>
<web-resource-collection>
<web-resource-name>Disable TRACE</web-resource-name>
<url-pattern>/</url-pattern>
<http-method>TRACE</http-method>
</web-resource-collection>
<auth-constraint/>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>Enable everything but TRACE</web-resource-name>
<url-pattern>/</url-pattern>
<http-method-omission>TRACE</http-method-omission>
</web-resource-collection>
</security-constraint>
-->

复制solr运行需要的文件到solr_home

cp solr-7.2.1/server/solr/* /opt/solr_home/ -rf

cp -rf solr-7.2.1/dist/ /opt/solr_home/

cp -rf solr-7.2.1/contrib/ /opt/solr_home/

启动tomcat



这里一定要加上 index.html 要不然就会404



这样就算成功了
