Install and configure sudo in CentOS 7

Sudo is usually referred to as super do or suitable user do. It is a software that uses the security permissions of other users to execute programs in UNIX-like operating systems. Let's see how to configure sudo.

# Mongodo

This will open/etc/sudoers and edit it.

Sudoers file

  1. Grant all permissions (equivalent to root) to a created user (such as tecmint ).

    Tecmint ALL = (ALL) ALL

  2. If a user (such as tecmint) has been created with all permissions except restarting and disabling the server (equivalent to root ).

    First, open the file again and edit the following content:

    Cmnd_Alias nopermit =/sbin/shutdown,/sbin/reboot

    Then, use the logical operator (!) Add this alias

    Tecmint ALL = (ALL) ALL ,! Nopermit

  3. If a group (such as debian) is allowed to run some root permission commands, such as adding or deleting users ).

    Cmnd_Alias permit =/usr/sbin/useradd,/usr/sbin/userdel

    Then, add permissions to the debian group.

    Debian ALL = (ALL) permit
