安装环境
[root@yfm05 data]# cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)
[root@yfm05 data]# java -version
java version "1.8.0_271"
Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)
solr下载地址：https://archive.apache.org/dist/lucene/solr/
我这里下载的是solr-8.8.1.tgz
mkdir /data/solr && cd /data/solr
tar -zxvf solr-8.8.1.tgz
cd solr-8.8.1/bin
启动
./solr start -p 8983 -force
浏览器访问
http://192.168.199.105:8983/
solr和tomcat整合
vi /etc/profile
export SOLR_INSTALL_HOME=/data/solr/solr-8.8.1
export PATH=$SOLR_INSTALL_HOME/bin:$PATH
source /etc/profile
solr应用在SOLR_ROOT/server/solr-webapp/webapp，把solr应用复制到tomcat的webapps下，将命名为solr
cp -r /data/solr/solr-8.8.1/server/solr-webapp/webapp /data/tomcat/apache-tomcat-7.0.107/webapps/solr
拷贝jar文件
cp -r /data/solr/solr-8.8.1/server/lib/ext/* /data/tomcat/apache-tomcat-7.0.107/webapps/solr/WEB-INF/lib
cp /data/solr/solr-8.8.1/server/lib/metrics-* /data/tomcat/apache-tomcat-7.0.107/webapps/solr/WEB-INF/lib/
mkdir -p /data/solr/solrhome
配置tomcat→webApp→solr→WEB_INF下的web.xml
添加配置（指定solr数据源的位置）
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/data/solr/solrhome</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
注释一下配置（目的是防止tomcat 403问题）
<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>
mkdir -p /data/solr/solrhome/logs
把solr安装包中的server→resources文件下的配置文件拷贝到tomcat→webApp→solr→WEB_INF→classes文件夹下（如果没有classes文件夹，请创建）
cp -r /data/solr/solr-8.8.1/server/resources/* /data/tomcat/apache-tomcat-7.0.107/webapps/solr/WEB-INF/classes
需要分别修改log4j2的两个配置文件，需要把所有${sys:solr.log.dir}修改为自己的指定的真实路径
启动tomcat，查看tomcat日志

记得带上index.html，坑了我好久，很多文章都没带
访问http://192.168.199.105:8080/solr/index.html#/
若有问题，换tomcat8试试
