tomcat 7无法进入管理页面 

在tomcat-users.xml中添加了以下代码即可

<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.
-->

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

</tomcat-users>
