打开tomcat的远程调试端口，三行脚本搞定

#!/bin/bash
# file: $CATALINA_HOME/bin/debug.sh
export JPDA_DEBUG="-Xdebug -Xrunjdwp:transport=dt_socket,address=5469,server=y,suspend=n"
export JAVA_OPTS="$JAVA_OPTS $JPDA_DEBUG"
./startup.sh

把文件保存在tomcat的bin目录下debug.sh

chmod +x debug.sh

sh debug.sh

出现监听程序就可以调试了，前提是防火墙没有屏蔽端口。

[admin@localhost bin]$ netstat -ntlp | grep 5469
