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?

||||

|
||||
* **[Two Methods To Create Bulk Users In Linux][2]**
|
||||
|
||||
|
||||
|
||||
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.
|
||||
|
||||
```
|
||||
+-----------------------------------------------------------------------+
|
||||
|username:password:UID:GID:Comments:User Home Directory:User Login Shell|
|
||||
+-----------------------------------------------------------------------+
|
||||
| | | | | | |
|
||||
1 2 3 4 5 6 7
|
||||
|
||||
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
|
||||
drwx------. 2 tuser2 tuser2 59 Jun 17 09:46 .
|
||||
drwxr-xr-x. 15 root root 4096 Jun 17 09:46 ..
|
||||
-rw-------. 1 tuser2 tuser2 18 Jun 17 09:46 .bash_logout
|
||||
-rw-------. 1 tuser2 tuser2 193 Jun 17 09:46 .bash_profile
|
||||
-rw-------. 1 tuser2 tuser2 231 Jun 17 09:46 .bashrc
|
||||
```

# 在 Linux 中不使用 useradd 命令如何创建用户账号
|
||||
|
||||
Linux 中有三个命令可以用来创建用户账号。
|
||||
|
||||
你尝试过在 Linux 中手动创建用户吗？
|
||||
|
||||
我的意思是不使用上面说的三个命令。
|
||||
|
||||
如果你不知道怎么做，本文可以手把手教你，并向你展示细节部分。
|
||||
|
||||
你有没有想过，这怎么可能？别担心，正如我们多次提到的那样，在 Linux 上任何事都可以搞定。这只是其中一例。
|
||||
|
||||
是的，我们可以做到的。想了解更多吗？
|
||||
|
||||
- **[在 Linux 中创建用户的三种方法][1]**
|
||||
- **[在 Linux 中批量创建用户的两种方法][2]**
|
||||
|
||||
话不多说，让我们开始吧。
|
||||
|
||||
首先，我们要找出最后创建的 UID 和 GID 信息。 掌握了这些信息之后，就可以继续下一步。
|
||||
|
||||
```
|
||||
# cat /etc/passwd | tail -1
|
||||
|
||||
tuser1:x:1153:1154:Test User:/home/tuser1:/bin/bash
|
||||
```
|
||||
|
||||
根据以上输出，最后创建的用户 UID 是 1153，GID 是 1154。为了试验，我们将在系统中添加 `tuser2` 用户。
|
||||
|
||||
现在，在`/etc/passwd` 文件中添加一条用户信息。 总共七个字段，你需要添加一些必要信息。
|
||||
|
||||
```
|
||||
+-----------------------------------------------------------------------+
|
||||
|username:password:UID:GID:Comments:User Home Directory:User Login Shell|
|
||||
+-----------------------------------------------------------------------+
|
||||
| | | | | | |
|
||||
1 2 3 4 5 6 7
|
||||
|
||||
1- 用户名: 这个字段表示用户名称。字符长度必须在 1 到 32 之间。
|
||||
2- 密码 (x): 表示存储在 /etc/shadow 文件中的加密密码。
|
||||
3- 用户 ID: 表示用户 ID(UID)，每个用户都有独一无二的 UID。UID(0)保留给root用户，UID(1-99)保留给系统用户，UID (100-999)保留给系统账号/组。
|
||||
4- 组 ID(GID): 表示 ID(GID) ，每个用户组都有独一无二的 GID，存储在 /etc/group 文件中。
|
||||
5- 注释/用户 ID 信息: 表示命令字段，用于描述用户信息。
|
||||
6- 主目录 (/home/$USER): 表示用户的主目录。
|
||||
7- shell (/bin/bash): 表示用户使用的 shell。
|
||||
```
|
||||
|
||||
在文件最后添加用户信息。
|
||||
|
||||
```
|
||||
# vi /etc/passwd
|
||||
|
||||
tuser2:x:1154:1155:Test User2:/home/tuser2:/bin/bash
|
||||
```
|
||||
|
||||
你需要创建相同名字的用户组。同样地，在`/etc/group`文件中添加用户组信息。
|
||||
|
||||
```
|
||||
# vi /etc/group
|
||||
|
||||
tuser2:x:1155:
|
||||
```
|
||||
|
||||
做完以上两步之后，给用户设置一个密码。
|
||||
|
||||
```
|
||||
# passwd tuser2
|
||||
|
||||
Changing password for user tuser2.
|
||||
New password:
|
||||
Retype new password:
|
||||
passwd: all authentication tokens updated successfully.
|
||||
```
|
||||
|
||||
最后，试着登录新创建的用户。
|
||||
|
||||
```
|
||||
# ssh [email protected]
|
||||
|
||||
[email protected]'s password:
|
||||
Creating directory '/home/tuser2'.
|
||||
|
||||
$ls -la
|
||||
|
||||
total 16
|
||||
drwx------. 2 tuser2 tuser2 59 Jun 17 09:46 .
|
||||
drwxr-xr-x. 15 root root 4096 Jun 17 09:46 ..
|
||||
-rw-------. 1 tuser2 tuser2 18 Jun 17 09:46 .bash_logout
|
||||
-rw-------. 1 tuser2 tuser2 193 Jun 17 09:46 .bash_profile
|
||||
-rw-------. 1 tuser2 tuser2 231 Jun 17 09:46 .bashrc
|
||||
```
