CATATAN UBUNTU POS

gagalllll…autoogin ubuntu

Create the folder: /etc/systemd/system/getty@tty1.service.d

Create the file: /etc/systemd/system/getty@tty1.service.d/override.conf

Open the file with your favorite editor and add this:

[Service]
ExecStart=
ExecStart=-/sbin/agetty --noissue --autologin myusername %I $TERM
Type=idle

mkdir -p /etc/systemd/system/getty@tty1.service.d/

Create a file at /etc/systemd/system/getty@tty1.service.d/autologin.conf with contents:

[Service]
ExecStart=
ExecStart=-/sbin/agetty –autologin USERNAME –noclear %I \$TERM

You can use ‘mingetty’ to autologin.

sudo apt-get install mingetty

Then edit /etc/init/tty1.conf

Change the line saying

exec /sbin/getty -8 38400 tty1

Into

exec /sbin/mingetty --autologin root --noclear tty1

Yes you can. As described here (ubuntuhandbook.org – Boot into text console ubuntu) you need to edit /etc/default/grub to have the next boot end up in text mode. In summary you will set these parameters:

GRUB_CMDLINE_LINUX="text"
GRUB_TERMINAL=console

After saving changes you need to run:

sudo update-grub

RC.LOCAL di UBUNTU

1. Create a service:

   sudo vi /etc/systemd/system/rc-local.service
   

2. Add your code there:

   [Unit]
   Description=/etc/rc.local Compatibility
   ConditionPathExists=/etc/rc.local
   
   [Service]
   Type=forking
   ExecStart=/etc/rc.local start
   TimeoutSec=0
   StandardOutput=tty
   RemainAfterExit=yes
   SysVStartPriority=99
   
   [Install]
   WantedBy=multi-user.target
   

3. Create and make sure /etc/rc.local is executable and add this code inside it:
   

   sudo chmod +x /etc/rc.local

   #!/bin/sh -e
   #
   # rc.local
   #
   # This script is executed at the end of each multiuser runlevel.
   # Make sure that the script will "exit 0" on success or any other
   # value on error.
   #
   # In order to enable or disable this script just change the execution
   # bits.
   #
   # By default this script does nothing.
   
   exit 0
   

4. Enable the service:

   sudo systemctl enable rc-local
   

5. Start service and check status:

   sudo systemctl start rc-local.service
   sudo systemctl status rc-local.service
   

6. If all goes well you can add your code to the /etc/rc.local file then restart it.

sudo systemctl set-default multi-user.target

# grub2-mkconfig -o /boot/grub2/grub.cfg

# grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

Make /etc/rc.local works in CentOS 7

Due to systemd introduced in CentOS 7, the /etc/rc.local not enabled by default, you should make /etc/rc.local executable by your hand.

Just run

and restart your CentOS 7 , see if it works
