今天在給jboss7.1控制檯新建用戶老是報錯，如下：
[czhwin@chenle bin]$ ./add-user.sh
What type of user do you wish to add?
a) Management User (mgmt-users.properties)
b) Application User (application-users.properties)
(a):
Enter the details of the new user to add.
Realm (ManagementRealm) : admin
Username : admin
Password :
Re-enter Password :
* Error *
JBAS015238: Username must not match the password.
原因是用了admin用戶名，密碼也是admin，JBoss7認爲太簡單了，後來換了個密碼就可以了，如下：
1,首先把jboss-as-7.1.1.Final/standalone/configuration/mgmt-users.properties和/jboss-as-7.1.1.Final/domain/configuration/mgmt-users.properties 這兩個文件中#admin=*******************，這行給刪除，不刪除到話，新建admin用戶就會有報錯"JBAS015243: The user 'admin' already exists in at least one properties file."
2.下面新建admin用戶
[czhwin@chenle bin]$ ./add-user.sh
What type of user do you wish to add?
a) Management User (mgmt-users.properties)
b) Application User (application-users.properties)
(a): a
Enter the details of the new user to add.
Realm (ManagementRealm) :
Username : admin
Password :
Re-enter Password :
The username 'admin' is easy to guess
Are you sure you want to add user 'admin' yes/no? yes
About to add user 'admin' for realm 'ManagementRealm'
Is this correct yes/no? yes
Added user 'admin' to file '/home/czhwin/tools/jboss-as-7.1.1.Final/standalone/configuration/mgmt-users.properties'
Added user 'admin' to file '/home/czhwin/tools/jboss-as-7.1.1.Final/domain/configuration/mgmt-users.properties'
3.http://localhost:9990 輸入admin和密碼，登錄管理後臺成功
