7 - Cập nhật hệ thống Centos 7
[1] Sau khi cài đặt xong hệ điều hành CentOS 7, bạn nên cập nhật các update mới nhất để đảm bảo an toàn và bảo mật. (lưu ý các Server cài OS phải cài đặt driver RAID riêng - OS ko tự nhận - thì hết sức lưu ý khi cập nhật OS này, vì sẽ rất dễ lỗi Kernel Panic do driver Raid cũ không load được )
