Bash sudo command not found centos 7/6 or Redhat

If you are trying to run some command with sudo and getting an error

bash: sudo: command not found

su and sudo are two different things, the above error means the system doesn’t have the sudo installation. Thus, here is the solution:

Login as a root user

First you should have root rights of your system.
Type:

su -

The above command will ask for your root user password.

Install Sudo on CentOS Linux

Now simply run the command:

yum install sudo 

Output of above command:
