Tomcat知识连载---Tomcat启动脚本catalina.sh

Tomcat启动脚本catalina.sh
1 - 概述
脚本catalina.sh用于启动和关闭tomcat服务器，是最关键的脚本。另外的脚本startup.sh和shutdown.sh都是使用不同的参数调用了该脚本。
该脚本的使用方法如下（引自该脚本本身）：
echo "Usage: catalina.sh ( commands ... )"
echo "commands:"
echo " debug Start Catalina in a debugger"
echo " debug -security Debug Catalina with a security manager"
echo " embedded Start Catalina in embedded mode"
echo " jpda start Start Catalina under JPDA debugger"
echo " run Start Catalina in the current window"
echo " run -security Start in the current window with security manager"
echo " start Start Catalina in a separate window"
echo " start -security Start in a separate window with security manager"
echo " stop Stop Catalina"
