Adding General Users
Root is a privileged user and should not normally be logged in as root.
You must create your own account separate from root. Create a login user with the following command
|
1 2 3 4 5 |
# useradd huong # passwd huong New password: Retype new password: passwd: password updated successfully |
Create user's home directory
|
1 2 |
# mkdir -pv /home/huong # chown -R huong:huong /home/huong |
Setting up the use of the sudo command
To grant sudo privileges to the created general user, use the command "visudo" as root and edit the file "sudoers".
This time, "users belonging to the wheel group can use it; they will not be asked for their password when sudoing." Use the

# visudo Uncomment line 82 ## Uncomment to allow members of group wheel to execute any command %wheel ALL=(ALL) ALL ←It can be used by users who belong to the wheel group. You will be asked for your own login password. Uncomment line 85 ## Same thing without a password %wheel ALL=(ALL) NOPASSWD: ALL ←It can be used by users who belong to the wheel group. No password required。 Uncomment line 88 ## Uncomment to allow members of group sudo to execute any command %sudo ALL=(ALL) ALL ←Any user with a registered account can use sudo. |

Uncomment line 60. ## Uncomment to use a hard-coded PATH instead of the user's to find commands Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" ←Uncomment and Activate |
Registration to wheel group
Register the created user huong to the wheel group
Display the group to which the current huong belongs
|
1 2 |
# groups huong huong : huong |
It still belongs only to the huong group.
We will add it to the wheel group so that sudo can be used.
Enter it in the format usermod -G {group to belong to} {username}.
|
1 |
# usermod -aG wheel huong |
Check your group affiliation
|

# groups huong huong : huong wheel |

If you are using the system in a Japanese environment (not used this time)
Do it with "root" user authority
