Unable to open debugger port in intellij. The port number 9009 matches the one which has been set in the configuration file for the application.
You must set CHMOD +x (execute for *.sh or *.bat files). For example, I am using macOS
cd /Users/donhuvy/Documents/tools/apache-tomcat-9.0.12/bin sudo chmod +x *.sh
Then IntelliJ IDEA, and Apache Tomcat running or debugging just good.
