从你提供的`server.xml`文件来看，`tomcat-users`元素是在`http://tomcat.apache.org/xml`命名空间下定义的，因此需要使用相应的命名空间前缀来引用该元素。

根据你的配置文件内容，将以下行：

<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">

修改为：

<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"
              xmlns:ns2="http://tomcat.apache.org/xml">

然后，在以下行中添加命名空间前缀 `ns2`：

<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>

修改为：

<ns2:role rolename="tomcat"/>
<ns2:role rolename="role1"/>
<ns2:user username="tomcat" password="tomcat" roles="tomcat"/>
<ns2:user username="both" password="tomcat" roles="tomcat,role1"/>
<ns2:user username="role1" password="tomcat" roles="role1"/>

这样修改后，`tomcat-users`元素及其子元素应该能被正确识别了。记得保存修改后的文件并重新启动Tomcat服务器。如果还有其他问题，请提供更多错误信息以便我能够帮助你进一步调试。
