Linux Change Default User Home Directory

Linux Change Default User Home Directory While Adding A New User


By default base directory for the system user is set to /home directory. I'd like to add user to /iscsi/home/${user} directory instead of the default /home. How do I force useradd command to add user to /iscsi/home under CentOS / RHEL / Fedora Linux server?

Default values for account creation defined in /etc/default/useradd file under CentOS / RHEL / Fedora / Debian / Ubuntu and other Linux distros. Simply open this file using a text editor, type:

 # vi /etc/default/useradd

The default home directory defined by HOME variable, find line that read as follows:
HOME=/home
Replace with:
HOME=/iscsi/user

Save and close the file. Now you can add user using regular useradd command:  # useradd vivek
# passwd vivek

Verify user information:
# finger vivek

Output:
Login: vivek                            Name: Vivek Gite
Directory: /iscsi/user/vivek                Shell: /bin/bash

How Do I Change Existing User's Home Directory?

You need to use the usermod command to set the user's new login directory. The syntax is as follows:
 
usermod -m -d /path/to/new/home/dir userNameHere
 
Where,
  1. -d dirnanme : Path to new login (home) directory.
  2. -m : The contents of the current home directory will be moved to the new home directory, which is created if it does not already exist.
In this example set the user's new login directory to /users/v/vivek from /home/vivek, enter:

# usermod -m -d /users/v/vivek vivek
