Centos 7 Migration Guide from Centos 6

Centos 7 is no cakewalk, there are many fundamental features and basic utilities that are missing or even completely renamed or different!

Another shocking thing is to check your NIC it is set by default to not turn on when booting!

And by the way there is no more standard eth0 the NIC convention is now "enp0s3"

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3

Set

onboot=yes

 

List of utilities and how to get them:

 

ifconfig

yum -y install net-tools

killall

yum -y install psmisc
