Last først ned ISO-installasjonsfilen for CentOS Linux 7, som bruker Minimal ISO. Den nedlastede ISO-filen blir skrevet til USB-flashstasjonen ved å bruke Fedora Media Writer. Minimal ISO er en minimal installasjon, vanligvis kan det enkelt settes opp i det grafiske grensesnittet, for eksempel å stille inn tidssone, harddiskpartisjon, innstille passordet til rotbrukeren og andre settbare elementer.

Etter å ha ventet på at installasjonen skal fullføres, kan du starte dhcp-tjenesten for å få maskinens ip-adresse, slik at vi kan logge på via ssh-programvaren og deretter utføre kommandoen.
