centos7如何设置成开机默认命令行模式以及登陆账户为root

Question

systemd方式如何修改？

Answer 1

CentOS7 no longer uses the init hosting service, but changed it to systemd. Naturally, the /etc/inittab file is no longer needed.

ln -sf /lib/systemd/system/multi-user.target /etc/systemd/system/default.target

Answer 2

1, command mode
systemctl set-default multi-user.target
2.Graphic mode
systemctl set-default graphical.target

Answer 3

CentOS sets the default startup command line (does not start the graphical interface)
CentOS implements root automatic login

For this matter, please google it yourself.
