Tomcat logon Manager Configuration

I have been exploring for a while after all.
Original tomcat-user.xml is
<? XML version = "1.0" encoding = "UTF-8 "? >
-<Tomcat-users>
<Role rolename = "Tomcat"/>
<Role rolename = "role1"/>
<User Username = "both" Password = "Tomcat" roles = "tomcat, role1"/>
<User Username = "Tomcat" Password = "Tomcat" roles = "Tomcat"/>
<User Username = "role1" Password = "Tomcat" roles = "role1"/>
</Tomcat-users>
==========================================
Here, role only has the permissions of Tomcat role1, while Tomcat 5.5 needs to be managed by clicking "Tomcat Manager ".
This is because the permission is incorrect.
Now that you know the problem, let's solve it,
1. Disable tomcat5.5
2. Open the tomcat-user.xml (under the conf folder), add a "manager" permission, and add
Login Name Admin, login password admin user, specify its permissions to Manager. The modified tomcat-user.xml is as follows:
======================================
<? XML version = '1. 0' encoding = 'utf-8'?>
<Tomcat-users>
<Role rolename = "Tomcat"/>
<Role rolename = "role1"/>
<Role rolename = "manager"/>
<Role rolename = "admin"/>
<User Username = "Tomcat" Password = "Tomcat" roles = "Tomcat"/>
<User Username = "both" Password = "Tomcat" roles = "tomcat, role1"/>
<User Username = "role1" Password = "Tomcat" roles = "role1"/>
<User Username = "admin" Password = "admin" roles = "manager"/>
</Tomcat-users>
==========================================
3. Save the tomcat-user.xml and restart tomcat5.5,
Enter http: // 127.0.0.1: 8080/to view the familiar Tomcat interface. Click "Tomcat Manager" and enter the username admin,
Password Admin. The Management page is displayed.
