Java ubuntu 14.04.1上的Apache tomcat7在部署war时出现404错误，在manager时出现401错误

我已经在ubuntu服务器上的tomcat7上部署了war。在点击ip:8080链接时，我成功地获得了tomcat7主页

如果这进一步有帮助，我已经按照给出的步骤进行了操作

因此，现在tomcat7是作为一项服务安装的。 为了部署war，我只需停止tomcat，然后将myapp.war文件放在webapps目录中。然后我启动了tomcat服务器。catalina的日志显示了以下内容（跳过不必要的行）：

当我尝试访问ip:8080/myapp url时，这给了我404错误

然后我尝试下载适用于apache的windows二进制文件，然后将war放在webapps中，然后启动.bat（在另一台windows机器上）。这非常有效（因此证明war文件和/或其web.xml没有任何问题）。但只有在linux上，才会出现404问题。我看到了所有与类似问题相关的答案，其中大多数建议访问manager应用程序。所以我用sudoapt-get安装了manager应用程序。安装成功。但不幸的是，它在ip:8080/manager上显示了一个用户名和密码字段。 这需要修改tomcat-users.xml文件，下面是我的：

  <user username="role1" password="tomcat" roles="role1"/>

</tomcat-users>

我尝试输入tomcat7和s3cret作为凭据，但没有被接受，再次弹出询问用户名和密码的框。我不知道为什么会这样。从我的角度来看，似乎没有什么问题，因为这是安装tomcat和部署war文件的方法（这不是我第一次这么做），所以它也应该对我有用

请有人提供解决相同问题的指南。

我认为您应该将问题分为两部分，一部分用于应用程序部署，另一部分用于经理。这样你将有更好的机会得到好的答案。你应该检查日志中的stacktrace/错误消息/var/lib/tomcat7/logs/catalina.out似乎“标准”角色尚未定义。。。
