Tomcat错误-Port already in use

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"
