<1> 建立一个关机角色，并设置密码：
| [root@node01 /]#roleadd –m –d /export/home/norshut norshut [root@node01 /]#passwd norshut |
<2> 定义角色的权限配置(right profile):
这里要编辑/etc/security/prof_attr文件。
[root@node01 /]#echo "shutdown:suser:::This role can execute shutdown">>/etc/security/prof_attr
<3> 定义权限配置的可用特权：
这里编辑/etc/security/exec_attr文件.
[root@node01 /]#echo "shutdown:suser:cmd:::/usr/sbin/shutdown:uid=0">>/etc/security/exec_attr
<4> 把权限配置和角色关联：
[root@node01 /]# rolemod –P “shutdown” norshut
注：在创建新用户的同时可用指定-R参数直接指定新用户帐号的角色。
<5> 添加新用户并把角色赋予新用户：
|
[root@node01 /]#useradd –g student –m –d /export/home/usrer01 –R norshut user01 |
如果在添加新用户时没有使用-R参数可以使用下面的命令将角色赋予新用户：
[root@node01 /]# usermod –R norshut user01
<6> 新角色：
| [root@node01 /]# su - user01 Sun Microsystems Inc. SunOS 5.10 Generic January 2005 -bash-3.00$ cat /etc/user_attr # # Copyright 2007 Sun Microsystems, Inc.
