解决方法：

先进入manager所在目录
[root@localhost tomcat]# cd webapps/manager/WEB-INF/
查看 web.xml
[root@localhost WEB-INF]# more  web.xml

  <!-- Define a Security Constraint on this Application -->
  <!-- NOTE:  None of these roles are present in the default users file -->
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>HTML Manager interface (for humans)</web-resource-name>
     <span> <url-pattern>/html/*</url-pattern> 对应:http://localhost:8080/manager/html</span>
    </web-resource-collection>
    <auth-constraint>
      <span> <role-name>manager-gui</role-name> 定义了访问这个页面的角色名：manage-gui</span>
    </auth-constraint>
  </security-constraint>
  <security-constraint>
    <web-resource-collection>
      <web-resource-name>Text Manager interface (for scripts)</web-resource-name>

    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-script</role-name>

    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-jmx</role-name>
    </auth-constraint>
  </security-constraint>

  <security-constraint>
    <web-resource-collection>
      <web-resource-name>Status interface</web-resource-name>
    <span> <url-pattern>/status/*</url-pattern> 对应：http://localhost:8080/manager/status  </span>
    </web-resource-collection>
    <auth-constraint>
      <span> <role-name>manager-gui</role-name> </span>
       <role-name>manager-script</role-name>
       <role-name>manager-jmx</role-name>
       <role-name>manager-status</role-name>
    </auth-constraint>
  </security-constraint>

进入host-manager所在目录
[root@localhost tomcat]# cd webapps/host-manager/WEB-INF/
查看 web.xml
[root@localhost WEB-INF]# more  web.xml

  <security-constraint>
    <web-resource-collection>
      <web-resource-name>HTMLHostManager commands</web-resource-name>
      <url-pattern><span>/html/*</span></url-pattern> <span>对应：<span>http://192.168.14.219:8080/host-manager/</span>htm</span>l
    </web-resource-collection>
    <auth-constraint>
       <!-- NOTE:  This role is not present in the default users file -->
      <span> <role-name>admin-gui</role-name> 定义了管理角色名称</span></auth-constraint>
  </security-constraint>

  <!-- Security roles referenced by this web application -->
  <security-role>
    <description>
      <span>The role that is required to log in to the Host Manager Application HTML</span>
<span> interface</span>
    </description>
    <span><role-name>admin-gui</role-name></span>
  </security-role>
  <security-role>
    <description>
      The role that is required to log in to the Host Manager Application text
      interface
    </description>
    <role-name>admin-script</role-name>
  </security-role>

 

编辑Tomcat用户配置文件,添加角色
[root@localhost tomcat]# vi conf/tomcat-users.xml

<tomcat-users>
<!--
  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.
-->
<!--
  NOTE:  The sample user and role entries below are wrapped in a comment
  and thus are ignored when reading this file. Do not forget to remove
  <!.. ..> that surrounds them.
-->
<span><!-- 这里有个注释符号去掉，使下面的生效</span>
  <role rolename="tomcat"/>
  <role rolename="role1"/>
<!--添加管理页面访问角色-->
 <span> <role rolename="manager-gui"></role> </span>
 <span> <role rolename="admin-gui"></role></span>
  <span><user username="manager" password="manager" roles="manager-gui,admin-gui">>
  <user username="tomcat" password="tomcat" roles="tomcat"></user>
  <user username="both" password="tomcat" roles="tomcat,role1"></user>
  <user username="role1" password="tomcat" roles="role1"></user>
<span>--> 这里有个注释符号去掉，是下面的生效</span>
</user></span></span></tomcat-users>

重启 tomcat

[root@localhost tomcat]# ./bin/shutdown.sh
[root@localhost tomcat]# ./bin/startup.sh

总结：
虚拟目录/WEB-INF/web.xml一般定义了访问这个目录的安全角色名称，得知这个安全角色名称后便可在conf/tomcat-users.xml添加对应的访问角色，获得访问权限。（于是这里也是个黑客可以利用的后门。。。）
