tomcat7配置用戶的一點問題

tomcat7配置用戶時，與tomcat6不同。
會有一個錯誤。



1、tomcat不配置conf/tomcat-users.xml或者配置不對時。會發生以下錯誤：

點擊這三個功能時：

報一下錯誤：

2、tomcat配置conf/tomcat-users.xml：

解決辦法：
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>
 Note that for Tomcat 7 onwards, the roles required to use the manager application were changed from the single manager role to the following four roles. You will need to assign the role(s) required for the functionality you wish to access.


    manager-gui - allows access to the HTML GUI and the status pages
    manager-script - allows access to the text interface and the status pages
    manager-jmx - allows access to the JMX proxy and the status pages
    manager-status - allows access to the status pages only




本例添加：
<role rolename="manager"/>  
<role rolename="manager-gui"/>  
<role rolename="admin"/>  
<role rolename="admin-gui"/>  

<user username="tomcat" password="tomcat" roles="admin-gui,admin,manager-gui,manager"/>
