Tomcat的Manager显示403 Access Denied

管理tomcat的时候遇到了如下问题：

　　1.刚开始须要用户名密码，不知道用户名和密码是什么，可是输入什么都不正确。

　　解决办法：

　　本身在tomcat-users.xml中按格式添加用户 conf文件夹里面

　　默认是注释掉了的，这主要是考虑到服务器的安全，若是是本地测试，去掉如下这段注释，而后重启动服务器，再输入

　　 <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"/>

　　用户和密码都一目了然了。

 

 

　　2.进入manager界面以后，显示的是403 Access Denied。

　　解决办法：

　　在conf/tomcat-users.xml文件中看到这么一段话：

　　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.

　　也就是说，为了考虑安全，tomcat默认仍是没有manager-gui的管理权限的，若是想要使用manager

　　的话，须要自行加入管理权限（角色）。

　　须要加一个这样的权限（角色）

　　<role rolename="manager-gui"/>

　　而后再加到须要的用户名中去

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

　　这样OK了。
