org.apache.catalina.core.StandardServer.await A valid shutdown command was received via the shutdown port. Stopping the Server instance.

先说解决办法，根据报错端口查询是否有端口占用的情况，如果是运行中出错，很有可能是shutdown这个端口-->配置信息如下在server.xml中，随后还有一堆类似内存泄漏啊什么的，没营养。

如服务是一开始都启动不起来：https://blog.csdn.net/zfz1015/article/details/8637431

<Server port="8005" shutdown="SHUTDOWN">
