When testing http://localhost:8080/ in the browser, a 500 error will be reported. I thought it was a version problem before, so I changed the version, but later found out (access denied).

Find the Tomcat directory and modify the control permissions, as shown below:
At this time, Restart Tomcat and it's OK.

We enter the conf folder in the directory where Tomcat lives (this folder stores some configuration files of Tomcat)
Selected in the picture The server.xml file is the file where the port number we need to modify is stored, so we open it.
The blue part selected above is our port number. 8080 is the default port number, we can change it to 8089 and so on.
