useradd: unable to open password file 解决办法 useradd: error opening group file解决办法
转载自: http://hi.baidu.com/binbin_1988/item/cdb117dad817faf8ca0c3941一、故障报错:useradd: unable to open password file或者useradd: error opening group file
解决:
现象:
root用户用useradd加个普通用户提示:useradd: unable to open password file。
普通用户su root提示:密码错(我可以肯定密码是对了)。
解决办法:
1.首先检查下面四个文件是否加了权限保护
# lsattr /etc/passwd
------------- /etc/passwd
# lsattr /etc/shadow
----i-------- /etc/shadow
# lsattr /etc/gshadow
------------- /etc/gshadow
# lsattr /etc/group
----i-------- /etc/group
从结果来看/etc/shadow 和 /etc/group都加了保护。下一步就是去除保护
2.删除文件保护
# chattr -i /etc/shadow
# lsattr /etc/shadow
------------- /etc/shadow
# chattr -i /etc/group
# lsattr /etc/group
------------- /etc/group
3.添加用户试试
# useradd huangf
# passwd huangf
Changing password for user huangf.
New UNIX password:
BAD PASSWORD: it is too simplistic/systematic
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
添加用户成功了!!!!!
