Linux 影响useradd的文件按照①=》②=》③的模式进行用户的建立

*①：【/etc/login.defs 文件是当创建用户时，系统对账户管理的宏观规划】

[root@rhel52 etc]# vim /etc/login.defs

1 # *REQUIRED*
2 # Directory where mailboxes reside, _or_ name of file, relative to the
3 # home directory.If you _do_ define both, MAIL_DIR takes precedence.
4 # QMAIL_DIR is for Qmail
5 #
6 #QMAIL_DIRMaildir
7 MAIL_DIR/var/spool/mail
8 #MAIL_FILE.mail
9

12 # PASS_MAX_DAYS Maximum number of days a password may be used.
13 # PASS_MIN_DAYS Minimum number of days allowed between password changes.
14 # PASS_MIN_LENMinimum acceptable password length.
15 # PASS_WARN_AGE Number of days warning given before a password expires.
16 #
17 PASS_MAX_DAYS 99999
18 PASS_MIN_DAYS 0
19 PASS_MIN_LEN2
20 PASS_WARN_AGE 7

23 # Min/max values for automatic uid selection in useradd

*②：【/etc/default/useradd 文件是当创建用户时，系统对账户本身的共通属性】

[root@rhel52 etc]# vim /etc/default/useradd

1 # useradd defaults file
2 GROUP=100
3 HOME=/home #user home
4 INACTIVE=-1#not stop the account when expire
5 EXPIRE=#this day it will stop
6 SHELL=/bin/bash#shell cat
7 SKEL=/etc/skel #copy these file to new user's home【注意他的指向】

*③：【/etc/skel/* 文件是当创建用户时，系统对账户模板的个性应用】

[root@rhel52 etc]# vim /etc/skel/
