Deploy multiple tomcat

Below we write the detailed configuration process below for reference: (This example takes the configuration of three Tomcats as an example)
 1. Download apache-tomcat-7.0.63, and the downloaded file is apache-tomcat-7.0.63 . zip.
 2. Unzip the compressed package to the D:/div/ directory.
3. Modify the name of the decompressed folder to: tomcat7-8080
4. Create two copies of the folder in the D:/div/ directory and rename them to: tomcat7-8081, tomcat7-8082
5. Add environment variables: Right click on My Computer -> Select Properties -> Select Advanced -> Select Environment Variables: Add System Variables:
CATALINA_HOME_8080, its value is: D:\div\tomcat7 -8080 ;
CATALINA_HOME_8081, its value is: D:\div\tomcat7 -8081 ;
CATALINA_HOME_8082, its value is: D:\div\tomcat7 -8082 ;

6. Modify the startup port and shutdown port:
Enter the D:\div\tomcat7 -8081 \conf\ directory, open the server.xml file, and modify the following two places:
( 1) <Server port="8006" shutdown="SHUTDOWN"> 
Modify this port = "8006", the original default is: 8005 , so that its shutdown port does not conflict with another shutdown port.
( 2) <Connector port="8081" maxHttpHeaderSize="8192" maxThreads 
               = "150" minSpareThreads="25" maxSpareThreads="75" 
               enableLookups ="false" redirectPort="8443" acceptCount="100" 
               connectionTimeout ="20000" disableUploadTimeout="true" /> 
Modify port = "8081", the original default is "8080 ", so that its connection port does not conflict with the other one.
( 3) <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> 
Modify this port = "8010", the original default is: 8009, where AJP 1.3 Connector is defined.

7. Modify the contents of startup.bat and catalina.bat files:
( 1) Open the D:\div\tomcat7-8081 \bin\startup.bat file and replace all CATALINA_HOME with CATALINA_HOME_8081.
( 2) Open the D:\div\tomcat7-8081 \bin\catalina.bat file and replace all CATALINA_HOME with CATALINA_HOME_8081.
The configuration method of tomcat7-8082 is the same as that of configuring 
tomcat7-8081 .

8 . Start Tomcat, enter three different Tomcat installation directories on the command line, execute startup.bat, and start three Tomcats respectively. Then enter in the browser:
http://localhost:8080
http://localhost:8081 
http://localhost:8082
