错误现象：

root@tomcat2:[/usr]vim /data/tomcat2/bin/shutdown.sh

root@tomcat2:[/usr]/data/hstomcatinit.sh stop

Using CATALINA_BASE: /data/tomcat2

Using CATALINA_HOME: /data/tomcat2

Using CATALINA_TMPDIR: /data/tomcat2/temp

Using JRE_HOME: /usr/java/jdk1.6.0_41

Using CLASSPATH: /data/tomcat2/bin/bootstrap.jar:/data/tomcat2/bin/tomcat-juli.jar

错误: 代理抛出异常 : java.rmi.server.ExportException: Port already in use: 9999; nested exception is:

java.net.BindException: Address already in use

root@tomcat2:[/usr]

解决方法：

不能使用JAVA_OPTS，二者区别

# JAVA_OPTS (Optional) Java runtime options used when any command

# is executed.

# Include here and not in CATALINA_OPTS all options, that

# should be used by Tomcat and also by the stop process,

# the version command etc.

# Most options should go into CATALINA_OPTS.

# CATALINA_OPTS (Optional) Java runtime options used when the "start",

# "run" or "debug" command is executed.

# Include here and not in JAVA_OPTS all options, that should

# only be used by Tomcat itself, not by the stop process,

# the version command etc.

# Examples are heap size, GC logging, JMX ports etc.

修改后的配置：

  CATALINA_OPTS="-server -Xms1100M -Xmx1100M -Xss194k -XX:NewSize=300M -XX:MaxNewSize=400M -XX:MaxPermSize=128M -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:HeapDumpPath=$CATALINA_BASE/log/heap.hprof  -Dproject=gameserver -Djava.rmi.server.hostname=218.108.129.7 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.ssl=false -verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -Xloggc:$CATALINA_BASE/log/gc.log"
