problems encountered and their solutions :

1. Port conflict, Tomcat's port changed to 8081. The 8080 port is the internal port that Jenkins comes with, which is also the purpose of the above steps to change 8081.

2. After the Tomcat service starts, the page does not load properly. Workaround: Systemctl start Tomcat.service. Enter into/usr/local/tomcat/bin,./startup.sh so that starting Tomcat can be solved.
