尝试在虚拟主机公司的tomcat 8服务器上设置RMI。得到一些奇怪的问题。
所以第一位是JAVAOPT设置，将以下内容添加到setenv.sh rw-r - r-- 1 tentogive tentogive 2040 Sep 24 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（已打开它们），在这种情况下它是端口14648和23208，因此将它们作为监听器添加到server.xml，如下所示：
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="14648" rmiServerPortPlatform="23208" />
然后我在catalina.log中收到以下错误
