Java 设置端口时Tomcat RMI出现问题

试图在一家网络托管公司的Tomcat8服务器上设置RMI。遇到一些奇怪的问题

所以第一位是JAVAOPT设置，在setenv.sh中添加了以下内容 rw-r--r--1 tentogive tentogive 2040年9月24日20:03 configtest.bat

export JAVA_OPTS="-Djava.awt.headless=true -server -Xms48m -Xmx256m\
                        -Dcom.sun.management.jmxremote=true \
                        -Dcom.sun.management.jmxremote.ssl=false \
                        -Dcom.sun.management.jmxremote.port=14648 \
                        -Dcom.sun.management.jmxremote.authenticate=false \
                        -Djava.rmi.server.hostname=XX.XXX.XX.XXX"

Tomcat提供了这些设置，但我无法连接到jmx

JMX需要两个端口（已打开），在本例中是端口14648和23208，因此将它们作为侦听器添加到server.xml中，如下所示：

<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="14648" rmiServerPortPlatform="23208" />

---

From：此侦听器需要将catalina-jmx-remote.jar放在$catalina_HOME/lib中。它是？同样在文档rmiRegistryPortPlatform中：这取代了使用此侦听器时不应设置的com.sun.management.jmxremote.port系统属性的使用。你真的读过文档了吗？另外，你想使用

CATALINA\u OPTS

而不是

JAVA\u OPTS

——否则你不能用

shutdown.bat/shutdown.sh

关闭tomcat。
