How to Add a User and Grant Root Privileges on Ubuntu 16.04<\/strong><\/span><\/p>\n

Ubuntu 16.04 LTS<\/strong> provides you the ability to add a user<\/strong> for anyone who plans on accessing your server<\/a>. \u00a0Creating a user is a basic setup but an important and critical one for your server security<\/a>. In this tutorial, we will create a user and grant administrative access<\/strong>, known as root<\/strong>, to your trusted user.<\/p>\n

Pre-Flight Check<\/strong><\/span><\/h3>\n
    \n
  1. Open a terminal and log in as root<\/strong>.<\/li>\n
  2. Work on a Linux<\/strong> Ubuntu 16.04 server<\/li>\n<\/ol>\n

    Creating a User with Root Privileges<\/strong><\/span><\/h2>\n

    Step 1:<\/span> \u00a0Add The User<\/strong><\/h3>\n

    Create a username for your new user, in my example my new user is Tom:<\/p>\n

    <\/div> 
    adduser tom<\/code><\/pre> <\/div>\n
    You\u2019ll then be prompted to enter a password for this user.\u00a0 We recommend using a strong password because malicious bots are programmed to guess simple passwords. If you need a secure password, this third party\u00a0password generator<\/a>\u00a0can assist with creating one.<\/p>\n
     
     <\/div> 
    ~#adduser tomAdding user 'tom' ...Adding new group `tom' (1002) ...Adding new user `tom' (1002) with group `tom' ...Creating home directory `\/home\/tom' ...Copying files from `\/etc\/skel' ...Enter new UNIX password:Retype new UNIX password:passwd: password updated successfully<\/code><\/pre> <\/div>\n
    Note:<\/strong><\/span><\/p>\n
    Usernames should be lowercase and avoid special characters. If you receive the error below, alter the username.<\/p>\n
     
     <\/div> 
    ~#adduser Tomadduser: Please enter a username matching the regular expression configured via the NAME_REGEX[_SYSTEM] configuration variable. Use the '--force-badname' option to relax this check or reconfigure NAME_REGEX.<\/code><\/pre> <\/div>\n
     
     <\/div> 
    Enter the new value, or press ENTER for the defaultFull Name []:Room Number []:Work Phone []:Home Phone []:Other []:<\/code><\/pre> <\/div>\n
    Lastly, the system will ask you to review the information for accuracy. \u00a0Enter\u00a0Y<\/strong>\u00a0to continue to our next step.<\/p>\n
     
     <\/div> 
    Is the information correct? [Y\/n] Y<\/code><\/pre> <\/div>\n
    Step 2:<\/span> Grant Root Privileges<\/strong><\/h3>\n
    Assigning a user root access is to grant a user the highest power. \u00a0My user, Tom, can then make changes to the system as a whole, so it\u2019s critical to allow this access only to users who need it. Afterward, Tom will be able to use sudo<\/strong> before commands<\/a> that are usually designed to be used by the root user<\/a>.<\/p>\n
     
     <\/div> 
    usermod -aG sudo tom<\/code><\/pre> <\/div>\n
    Step 3:<\/span> Verify New User<\/strong><\/h3>\n
    As root, you can switch to your new user with the su \u2013 command<\/strong> and then test to see if your new user has root privileges.<\/p>\n
     
     <\/div> 
    su - tom<\/code><\/pre> <\/div>\n
    If the user has properly been granted root access the command below will show tom in the list<\/p>\n
     
     <\/div> 
    grep '^sudo' \/etc\/group<\/code><\/pre> <\/div>\n
    Output:<\/span><\/h3>\n
     
     <\/div> 
    sudo : x : 27 : tom<\/code><\/pre> <\/div>\n
