Question

我不确定为什么我无法登录，这是权限：

<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">
<!--
  NOTE:  By default, no user is included in the "manager-gui" role required
  to operate the "/manager/html" web application.  If you wish to use this app,
  you must define such a user - the username and password are arbitrary. It is
  strongly recommended that you do NOT use one of the users in the commented out
  section below since they are intended for use with the examples web
  application.
-->
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager-gui"/>
  <role rolename="admin-gui"/>
  <role rolename="manager-script"/>
  <user username="lamidotijjo" password="s3cr3t" roles="manager-gui,manager-script,admin-gui"/>
  <user username="tomcat" password="<must-be-changed>" roles="tomcat"/>
  <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>

</tomcat-users>

我昨天从tomcat官方网站为Ubuntu安装了它。我认为所有权限都是正确的。谢谢！

您的所有权限都是正确的，您添加的新用户也可以。问题是您没有在文件 tomcat-users.xml 中的这三个预先配置的用户上设置有效密码：

  <user username="tomcat" password="<must-be-changed>" roles="tomcat"/>
  <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>

Tomcat故意使用无效密码配置这些用户，强制您将其更改为有效的密码。如果在使用这些设置启动Tomcat后检查日志，您可能会看到几个与此类似的堆栈跟踪：

10-Jun-2018 00:04:35.343 INFO [main] org.apache.catalina.startup.Catalina.load Initialization processed in 902 ms
10-Jun-2018 00:04:35.386 SEVERE [main] org.apache.tomcat.util.digester.Digester.fatalError Parse Fatal Error at line 48 column 34: The value of attribute "password" associated with an element type "user" must not contain the '<' character.
 org.xml.sax.SAXParseException; lineNumber: 48; columnNumber: 34; The value of attribute "password" associated with an element type "user" must not contain the '<' character.
        at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:203)
        at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177)

错误消息非常明确：

The value of attribute "password" associated with an element type "user" must not contain the '<' character.

只需将"<must-be-changed>"的每个实例替换为"password"（或您选择的某个密码），然后重新启动Tomcat以解决问题。

或者，如果您不需要这三个用户，您可以从文件中删除这三行（或将其注释掉）。
