Does anyone know how to enable debug mode during starting Centos 7 or Centos 6.5? I mean when any login issue comes for start Centos and we need to doing troubleshoot for the reason.

Appreciate much for any adivce.


for CentOS 7 you can use journald to get error messages during startup, messages will get removed after server reboot, if you want to keep them or have a easy access create the following folder

sudo mkdir /var/log/journal 
sudo systemd-tmpfiles --create --prefix /var/log/journal
sudo  systemctl restart systemd-journald
