Basic Settings for Linux users

Linux has super Administrators and ordinary users, each user when the basic settings after the establishment can be tested by the following explanations

• Create a normal user

[Email protected] ~]# useradd vforbox [[email protected] ~]# grep ' ^vfor '/etc/passwd                                        //See if Add success vforbox:x:502:502: :/home/vforbox:/bin/bash

• Basic settings for new users with/etc/login.defs and/etc/default/useradd two files when we create new users

[[email protected] ~]# cat/etc/login.defs           //View some basic properties of the user Mail_dir        /var/spool/mail              //mailbox default directory Storage Pass_max_   days 99999     //password need to change the time pass_min_days   0      //password how long to change Pass_min_len    5     //password Minimum length pass_warn_age   7     //password expires days before sending a warning message                   uid_min        //Default account start minimum UID number Uid_max                 60000//MAX UID limit gid_min                   500        ///Default account start minimum number of GID Gid_max                 60000//MAX UID limit create_home Yes//     whether to establish user root directory, default is yes, otherwise no no
