其实在创建用户的过程中，还会对几个目录进行修改，大致有以下几个：
/etc/passwd --用户密码
/etc/shadow --密钥文件
/etc/group --用户组
/etc/skel/.* --骨架文件
看一下这些文件中和oracle用户相关的内容：
[oracle@ora11g ~]$ cat /etc/passwd |grep oracle
oracle:x:54321:54321::/home/oracle:/bin/bash
[oracle@ora11g ~]$ cat /etc/shadow |grep oracle
cat: /etc/shadow: Permission denied
[oracle@ora11g ~]$ su - root
Password:
[root@ora11g ~]# cat /etc/shadow |grep oracle
