  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!!!!!
