解决方法：
修改tools.sh内的JAVA配置,添加jre/lib/ext目录
gedit tools.sh
修改：
将:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"
修改成:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext:/java/jdk1.8.0_241/jre/lib/ext"
【rocketMQ:mqadmin运行时报错org.apache.rocketmq.tools.command.SubCo..】注意:jdk11没有jre目录，需要手动下载
