Tomcat deployment, setting jdk environment, jvm memory, etc.

    A custom environment file can be specified in tomcat's catalina.sh file: setenv.sh

原文：setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

 

Therefore, add this file to the bin directory to set the environment and save it as setenv.sh
