安装完成之后，重新输入命令验证是否解决

[root@linux ~]# man 5 passwd
Cannot open the message catalog "man" for locale "zh_CN.UTF-8"
(NLSPATH="/usr/share/locale/%l/LC_MESSAGES/%N")

No entry for passwd in section 5 of the manual
[root@linux ~]# man
Cannot open the message catalog "man" for locale "zh_CN.UTF-8"
(NLSPATH="/usr/share/locale/%l/LC_MESSAGES/%N")

What manual page do you want?

还是不行，因为看到提示信息里面有open,所以没有直接尝试（2），选择继续去百度，百度给出的解释是没有安装man -pages,抱着试一试的心态继续操作安装man -pages

PASSWD(5)                  Linux Programmer’s Manual                 PASSWD(5)

NAME
       passwd - password file

DESCRIPTION
       Passwd  is  a text file, that contains a list of the system’s accounts,
       giving for each account some useful information like user ID, group ID,
       home  directory,  shell,  etc.   Often,  it also contains the encrypted
       passwords for each account.  It should  have  general  read  permission
       (many  utilities,  like ls(1) use it to map user IDs to usernames), but
       write access only for the superuser.

       In the good old days there was no great problem with this general  read
       permission.   Everybody  could  read  the  encrypted passwords, but the
       hardware was too slow to crack a well-chosen  password,  and  moreover,
       the  basic  assumption  used  to  be that of a friendly user-community.
       These days many people run some version of the shadow  password  suite,
       where  /etc/passwd  has  "x"  instead  of  encrypted passwords, and the
       encrypted passwords are in /etc/shadow which is readable by  the  supe-
       ruser only.

       If the encrypted password, whether in /etc/passwd or in /etc/shadow, is
       an empty string, login is allowed without even asking for  a  password.
       Note  that this functionality may be intentionally disabled in applica-
       tions, or configurable (for example  using  the  "nullok"  or  "nonull"
       arguments to pam_unix.so).

       If  the  encrypted  password  in  /etc/passwd  is  "*NP*"  (without the
       quotes), the shadow record should be obtained from a NIS+ server.

OK 搞定 嘻嘻~
