天网/cheetah前端tomcat 关闭脚本出错

$sudo -u etl ./bin/shutdown.sh

找了下,server.xml里没有监听这个端口,什么进程监听的?但是netstat看到的PID还就是这个tomcat的PID
$ sudo netstat -lantup|grep :9004

bin/catalina.sh:JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9004 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

是一个jconsole远程监控端口.

Unix/Linux平台：修改catalina.sh，在"run"和"start"段开头增加一行（注意是一行）：

JAVA_OPTS="$JAVA_OPTS "-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port="9004" -Dcom.sun.management.jmxremote.authenticate="false" -Dcom.sun.management.jmxremote.ssl="false" 

或者换成CATALINA_OPTS?看catalina.sh脚本中的说明:

#                   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   or "run" command is executed.

#   JAVA_OPTS       (Optional) Java runtime options used when the "start",
#                   "stop", or "run" command is executed.

既然不想要在stop时检查这个变量,CATALINA_OPTS不正符合要求?

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9004 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"
