User is not in The Sudoers file – SOLUTION
When I try to execute administrative commands with sudo command as a regular user it returns the following error.
How can i Fix this error and run commands with sudo. Our Server is Running Linux CentOS 7.
This is Because your user does not have sudo privileges. In CentOS there is an administrative group named wheel. Only the Members of the wheel group can run sudo command. To fix the error all you have to do is , add non root user to the wheel group. For that we can use Linux usermod command.
usermod -a -G wheel username
For Example In My Linux Server I have a user called sysadmin and if i want to give sysadmin user the sudo privileges, Type.
usermod -a -G wheel sysadmin
Now sysadmin user can run Linux Commands as administrator with sudo in front.
