由于在server.xml文件中使用配置了

在catalina.sh中也指定了对应

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12340 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.40.103"这里设置了对应的设置

catalina.out报错

解决办法 把文件server.xml中的 删除即可
