catalina.sh run starts tomcat in the foreground, displaying the logs on the console that you started it. Hitting Ctrl-C will terminate tomcat.
startup.sh will start tomcat in the background. You’ll have to tail -f logs/catalina.out to see the logs.
Both will do the same things, apart from the foreground/background distinction.
后续的流程就到了java代码里
Java代码中的启动流程
Bootstrap
The purpose of this roundabout approach is to keep the Catalina internal classes (and any other classes they depend on, such as an XML parser) out of the system class path and therefore not visible to application level classes.
