ubuntu - tomcat manage 403错误

Question

系统环境： ubuntu 12.04 tomcat-7

需要在界面中登陆managerApp界面：
已经修改了：conf/ tomcat-users.xml

1.自行建立

    <role rolename="manage"/>
    <role rolename="admin"/>
    <user username="admin" password="admin" roles="admin,manage"/>

报错403.修改了该文件的权限777,还是报错。
查看一些资料说是rolename不能够自己瞎定义。所以修改了如下代码：


<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="tomcat" password="123456" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/>
<user username="admin" password="admin" roles="admin-gui"/>

重启了tomcat还是出现403错误。
在欢迎界面中serverstatus 和hotmanager都能够通过第二次配置的密码登陆，并显示相应的内容，只有managerApp不能够通过第二次配置的帐号密码登陆。

求大神们解释解释这是为什么！！！！！

This is the modified answer.

After verification, I successfully accessed the Manager App. In fact, the first one of your questions username为tomcat的用户已经可以正常登陆了,只是又你写了一个错误的用户<user username="admin" password="admin" roles="admin-gui"/> (这里的 roles 应该是 manager-gui only works), so I can’t log in,

The following is the verification process: I logged in with the user <user username="admin" password="admin" roles="admin-gui"/>, and indeed an error 403 was reported.

Here is a piece of code that illustrates how to set permissions and passwords if you want to log in:

// 举个例子,想增加一个用户名是tomcat,密码是 s3cret 的 "manager-gui" 角色,则按照下面的配置:
For example, to add the manager-gui role to a user named tomcat with a password of s3cret, 
add the following to the config file listed above.

<role rolename="manager-gui"/>    
<user username="tomcat" password="s3cret" roles="manager-gui"/> // 这里的roles必须写对
