Ubuntu Serial Install

[Ubuntu 24.04.02]

많이 편해졌다. /boot/grub/grub.cfg 만 변경하면 된다.

How to install Ubuntu using serial console

This instruction show you how to install Ubuntu with serial console without VGA. We have tested the following instructions under UEFI boot and legacy boot mode.

USB boot-disk setup

1. Download an ubuntu server amd64 iso file
2. Create a USB boot disk using unetbootin
3. Modify the following files. If you still use legacy bios boot mode, modify isolinux/isolinux.cfg, isolinux/txt.cfg, syslinux.cfg. If you use UEFI boot mode, modify boot/grub/grub.cfg only.
   • isolinux/isolinux.cfg
   # D-I config version 2.0
   include menu.cfg
   default menu.c32
   prompt 0
   timeout 0
    
   • isolinux/txt.cfg
   default install
   label install
      menu label ^Install Ubuntu Server
      kernel /install/vmlinuz
      append vga=normal initrd=/install/initrd.gz -- console=tty0 console=ttyS0,115200n8 nosplash debug -
   
   
   • syslinux.cfg
   CONSOLE 0
   SERIAL 0 115200 0
   default menu.c32
   prompt 0
   menu title UNetbootin
   timeout 100
   
   label unetbootindefault
   kernel /ubnkern
   append vga=normal initrd=/ubninit nomodeset askmethod console=tty0 console=ttyS0,115200n8
   
   
   • boot/grub/grub.cfg
   Add serial console options and remove quiet option in the menuentry of "Insatall Ubuntu Server"
   
   menuentry "Install Ubuntu Server" {
      set gfxpayload=keep
      linux /install/vmlinuz file=/cdrom/preseed/ubuntu-server.seed vga=normal console=tty0 console=ttyS0,115200n8 ---
      initrd /install/initrd.gz
   }

Hardware configuration

1. Enter BIOS.
2. Setup serial port setting to allow console redirection.
   • Enter "Advanced Setup Configurations" Tab
     • Enter "Super IO Configuration" option
     • Serial Port 0 Configuration /Serial Port 1 Configuration Serial Port: Enabled
     • Enter "Serial Port Console Redirection" option
     • Terminal Type: VT100+ Bits Per second: 115200 Data Bits: 8 Bits Parity: None Stop Bits: 1 Flow Control: None VT-UTF8 Combo Key Support: Enabled Recorder Mode: Disabled Resolution 100x31: Enabled Legacy OS Redirection Resolution: 80x25 Putty KeyPad: VT100 Redirection After BIOS Post: Always Enable
3. Select boot partition
   • Enter "Boot" Tab
   Set UEFI USB disk boot or USB disk as first boot priority at Boot Option
4. Save current BIOS configuration and reboot

Client setup

1. Attach serial console from client

% screen /dev/ttyS0 115200

Ubuntu Installation

1. Proceed normal Ubuntu installation.
2. At the phase of GRUB installation, select your correct boot disk for boot loader. An Ubuntu 14.04 installation boot disk may be "/dev/sda" in case that you use USB boot.
3. /dev/sdb
4. Install SSH daemon and avahi-daemon to configure the system after this installation.
5. (Optional) When you see the dialog at "Finish the installation", check "" and select "start shell" to check host IP address in a DHCP environment with the following command.
6. $ ip addr show

First boot after the installation

1. Enter editing mode of grub boot option with key e, when you see grub boot menu on serial console.
2. Add console options after ro in linux boot options
3. linux ..... ro console=tty0 console=ttyS0,115200n8
4. Boot linux with current grub configuration by Ctrl-x

Post setup

1. Grub configuration
   • Edit /etc/default/grub as follows:
   GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_TERMINAL='serial console' GRUB_CMDLINE_LINUX="console=tty0 console=ttyS0,115200n8" GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"
   • Update grub configuration
   # update-grub
