error message:

[Root@localhost ~]# setup
-bash:setup:command not found

This is because your CentOS system does not have the Setup command by default, and there are no components that are associated with the Setup command tool. At this time, the Yum tool can be installed on the line one by one, the specific installation method is as follows.

yum-y install System-config-network-tui 
Install the Setup Tools Kit for the network configuration component

yum-y install AUTHCONFIG-GTK
Install the Setup tool kit for validation configuration

yum-y Install System-config-keyboard
Install the Setup tool's accompanying keyboard configuration component
