好的，我有一个主域：mainDM.com（这是名为mainDM的应用程序的域），是从Godaddy购买的。我还购买了IP地址xxx.xx.xx.xx的Godaddy Win2000 VPS。
在Godaddy中，我将该域指向xxx.xx.xx.xx。
在Tomcat服务器的webapps文件夹中，有一个ROOT文件夹，我将mainDM应用程序的所有html文件放入了ROOT文件夹中。一切正常。那就是当我打开mainDM.com时，我可以看到我的应用运行正常。
现在，我开发了另一个名为otherDM的应用程序，我还在Godaddy购买了域名otherDM.com，并将其指向xxx.xx.xx.xx。现在，当打开otherDM.com时，我没有看到otherDM应用程序，但看到了mainDM应用程序。所以我想配置server.xml，以便当我打开otherDM.com时，它将显示otherDM Web应用程序。注意：在otherDM文件夹中有一个otherDM文件夹，其中包含webapps应用程序的所有html文件。
这是我在server.xml所做的事情，但是什么也没发生。

我确实重新启动了Tomcat服务器，但是什么也没发生，每次我打开otherDM.com时，它都会显示mainDM应用程序。但是，如果我打开
otherDM.com/otherDM或打开mainDM.com/otherDM，则可以看到otherDM应用。我做错了吗？怎么修？
最佳答案
如果是相对的，则“主机”标记的“应用程序”属性指向CATALINA_HOME下的目录（如果有的话）。因此，只需创建两个文件夹，如下所示：
[CATALINA_HOME]/mainDomain
[CATALINA_HOME]/otherDomain
并在其中创建两个ROOT文件夹。将您的应用程序复制到ROOT目录中。
然后将应用程序库设置为：
<Host name="localhost" appBase="mainDomain" ...
<Host name="mainDomain.com" appBase="mainDomain" ...
<Host name="otherDomain.com" appBase="otherDomain" ...
