Create sudo user in ubuntu 18.04
In linux root user is having all rights and permissions to do all tasks.Due to some security reasons it is recommended to use the sudo command to gain root privileges when a system user really needs to. On Ubuntu systems, root account is disabled by default and the default account is an administrative account which uses sudo to obtain root privileges.
Step 1: First we will login into the root user
If we have root access then use below command
if you have default user account as test then
test@lampblogs:~$ sudo su - [sudo] password for test: root@lampblogs:~#
Step 2: create new user account
root@lampblogs:~# adduser bobby Adding user `bobby' ... Adding new group `bobby' (1001) ... Adding new user `bobby' (1001) with group `bobby' ... Creating home directory `/home/bobby' ... Copying files from `/etc/skel' ... Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully Changing the user information for bobby Enter the new value, or press ENTER for the default Full Name : Room Number : Work Phone : Home Phone : Other : Is the information correct? [Y/n] y
Step 3: Add user to sudo group
root@lampblogs:~# usermod -aG sudo bobby
Step 4: Test sudo Access
Now switch to new user like below
root@lampblogs:~# su - bobby To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details. bobby@lampblogs:~$
use sudo command ro run whoami command
bobby@lampblogs:~$ sudo whoami [sudo] password for bobby: root
First time you use sudo it will be prompted to enter the user password.Now you can run any administrative tasks.
bobby@lampblogs:~$ sudo mkdir -p /srv/www/test bobby@lampblogs:~$ cd /srv/www/test/ bobby@lampblogs:/srv/www/test$
Thats'it.Now we have successfully created sudo user in ubuntu system.
