Little white records step on the pit, please ignore the big guy

One server did not start automatically after it was restarted. One project needed to run in tomcat, so the command startup.sh was manually executed in the directory, but it was always prompted that the setclasspath.sh file was missing

 cannot find /root/XXX/apache-tomcat-8.5.42/bin/setclasspath.sh This file is need to run this program

But this file is clearly in the current directory, and I cannot understand it

I learned from Baidu under the reminding of Mr. Zhuang

Before starting tomcat, you must first execute unset CATALINA_HOME, or you will be prompted with this error and then execute it. Everything is normal
