How to Create a User Account Without useradd Command in Linux?
|
|||
|
|
======
|
|||
|
|
|
|||
|
|
There are three commands are available in Linux to create an user account.
|
|||
|
|
|
|||
|
|
Did you ever tried to create a user account in Linux using manual method?
|
|||
|
|
|
|||
|
|
I mean to say without using an above three commands.
|
|||
|
|
|
|||
|
|
If you don’t know how to do that? we are here to help you on this and will show you in details.
|
|||
|
|
|
|||
|
|
Have you wondering, how it’s possible? If yes, don’t worry, as we have mentioned many times that anything can be done on Linux. It is one of the example.
|
|||
|
|
|
|||
|
|
Yes, we can create it. Are you excited to know more it?

I don’t want to you to wait any more. Let’s do it right away.
|
|||
|
|
|
|||
|
|
To do so, first, we need to find out last created UID and GID information. Once you have these information handy then proceed to next step.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
# cat /etc/passwd | tail -1
|
|||
|
|
|
|||
|
|
tuser1:x:1153:1154:Test User:/home/tuser1:/bin/bash
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Based on the above output. Last created user UID is 1153 and GID is 1154. To experiment this, we are going to add `tuser2` in the system.
|
|||
|
|
|
|||
|
|
Now, add an entry of user details in /etc/passwd. There are seven fields exist and you need to add required details.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|

|

|
|
|
|||
|
|
1- Username: This field indicates the User name. Characters length should be between 1 to 32.
|
|||
|
|
2- Password (x): It indicates that encrypted password is stored at /etc/shadow file.
|
|||
|
|
3- User ID: It indicates the user ID (UID) each user should be contain unique UID. UID (0-Zero) is reserved for root, UID (1-99) reserved for system users and UID (100-999) reserved for system accounts/groups
|
|||
|
|
4- Group ID (GID): It indicates the group ID (GID) each group should be contain unique GID is stored at /etc/group file.
|
|||
|
|
5- Comment/User ID Info: It indicates the command field. This field can be used to describe the user information.
|
|||
|
|
6- Home directory (/home/$USER): It indicates the user's home directory.
|
|||
|
|
7- shell (/bin/bash): It indicates the user's shell.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Add the user information in end of the file.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
# vi /etc/passwd
|
|||
|
|
|
|||
|
|
tuser2:x:1154:1155:Test User2:/home/tuser2:/bin/bash
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You have to create a group with same name. So, add a group details in /etc/group file as well.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
# vi /etc/group
|
|||
|
|
|
|||
|
|
tuser2:x:1155:
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Once you done the above two steps, then set a password for user.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
# passwd tuser2
|
|||
|
|
|
|||
|
|
Changing password for user tuser2.
|
|||
|
|
New password:
|
|||
|
|
Retype new password:
|
|||
|
|
passwd: all authentication tokens updated successfully.
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Finally, try to login with newly created user.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
# ssh [email protected]
|
|||
|
|
|
|||
|
|
[email protected]'s password:
|
|||
|
|
Creating directory '/home/tuser2'.
|
|||
|
|
|
|||
|
|
$ls -la
|
|||
|
|
|
|||
|
|
total 16
