LS1012A Cannot login automatically as root

Hi!

I want to login automatically as root after the system boot and no password required! I've tried modify “/lib/systemd/system/getty@.service” content as follows：

annotate "#ExecStart=-/sbin/agetty -o '-p -- \\u' --noclear %I $TERM"

and add "ExecStart=-/sbin/agetty --autologin root --noclear %I $TERM" or "ExecStart=-/sbin/agetty -a root --noclear %I $TERM",but it didn't work!

Second:modify "/etc/passwd",change "root:x:0:0:root:/root:/bin/bash" to "root::0:0:root:/root:/bin/bash".

Now I don't need to enter a password,but still need to enter a user name "root".

Why doesn't it work?

Hello li yh,

Please edit /etc/init/tty1.conf and replace the exec /sbin/getty ... line with:

exec /sbin/getty -n -l /bin/sh -8 38400 tty1

Thanks,

Yiping

Hi!

Thank you for your reply！

But the file "tty1.conf" does not exist in the path "/etc/init/",

Is there any other way to solve this problem?

Please edit the file /lib/systemd/system/getty@.service and change the line

ExecStart=-/sbin/agetty --noclear %I $TERM

ExecStart=-/sbin/getty/ --noclear -a root %I $TERM

Hi!

Thank you for your reply！

Now I've found a way to solve this problem：

edit the file /lib/systemd/system/serial-getty@.service and change the line

ExecStart=-/sbin/agetty -o '-p -- \\u' --keep-baud 115200,38400,9600 %I $TERM

ExecStart=-/sbin/agetty -a root --keep-baud 115200,38400,9600 %I $TERM

Thanks for your help！
