CentOS 7 unable to login, display login incorrect immediately after input login name

Problem

Unable to login linux console, always show login incorrect for any login name

 

Why

Selected some security profile(e.g. PCI-DSS) during installation, but network connection is unavailable.

Installer unable to download some packages from the internet, and caused installation failure. You may feel the installation time longer than no security profile.

 

In my case is CentOS installer missing the web proxy settings 🙁

 

How to Fix

Select other security profile or setup correct network connection, and re-install the system.

 

Reference

CentOS-7 Installer Security Profiles

2.1. Requirements

These profiles require a connection to the internet to install. If you select a security profile that can not connect to the internet on port 80 (to mirror.centos.org), your install may fail spectacularly and not even allow access to the console locally. Please only try these profiles while connected to the internet.

Packages will be installed from the internet if you use security profiles, even if those packages also reside on the ISOs.
