Users

Create an admin user

To create an admin user, you can perform the following steps:

1. Run the following commands to create the admin user:

   useradd -U admin -d /home/admin -s /bin/bash
   mkdir -p /home/admin
   sudo chown -R admin:admin /home/admin
   

2. Run the following command to set a password for the admin user:

   passwd admin
   

3. Optional. Set sudo permissions for the admin user.

   Open the /etc/sudoers file. Add the following code to /etc/sudoers:

   ## Same thing without a password
   # %wheel        ALL=(ALL)       NOPASSWD: ALL
   admin       ALL=(ALL)       NOPASSWD: ALL
   

4. Run the following command in the /home directory to check whether the admin user is granted the permission to access the directory.

   ls --al
   

   The following output is returned:

   drwxr-xr-x 2 admin admin 4096 Feb. 9 18:43 
   drwxr-xr-x 2 admin admin 4096 Feb. 9 18:43 admin
   

   If the admin user does not have the access permission, run the following commands as the root user:

   chown -R admin:admin /data
   chown -R admin:admin /home/admin
   

   Note that you need to specify your actual mount directories. The /data and /home/admin directories in the preceding commands are only examples for your reference.
