No "setup" command on CentOS
I usually use "setup" to do the firewall setup for permissive or not and setting of SELINUX, etc….
But on a minimal install you don’t have access to setup command, which is my favorite
[root@tel ~]# setup
-bash: setup: command not found
So how to install it in minimal install ?
yum –y install setuptool
yum –y install system-config-network*
yum -y install system-config-firewall*
yum –y install system-config-securitylevel-tui
yum –y install system-config-keyborad
