Configuring Linux for Server Serial Console Redirection During Boot

1. Locate the general setting sections in the file and type the following two new lines:

   serial --unit=1 --speed=57600
   terminal --timeout=10 serial

2. Append two options to the kernel line:

   kernel console=ttyS1,57600

3. If the /etc/grub.conf contains a splashimage directive, comment it out.
   The following example shows the changes described in this procedure.

   # grub.conf generated by anaconda
   #
   # Note that you do not have to rerun grub after making
   changes
   # to this file
   # NOTICE: You do not have a /boot partition. This
   means that
   # all kernel and initrd paths are relative to
   /, e.g.
   # root (hd0,0)
   # kernel /boot/vmlinuz-version ro root=
   /dev/sdal
   # initrd /boot/initrd-version.img
   #
   #boot=/dev/sda
   default=0
   timeout=10
   #splashimage=(hd0,2)/grub/splash.xpm.gz
   serial --unit=1 --speed=57600
   terminal --timeout=10 serial
   title Red Hat Linux Advanced Server (2.4.9-e.3smp)
   root (hd0,0)
   kernel /boot/vmlinuz-2.4.9-e.3smp ro root=
   /dev/sda1 hda=ide-scsi console=ttyS0 console=
   ttyS1,57600
   initrd /boot/initrd-2.4.9-e.3smp.img
   title Red Hat Linux Advanced Server-up (2.4.9-e.3)
   root (hd0,00)
   kernel /boot/vmlinuz-2.4.9-e.3 ro root=/dev/sda1
   initrd /boot/initrd-2.4.9-e.3.img

   When you edit the /etc/grub.conf file, follow these guidelines:

   • Disable GRUB's graphical interface and use the text-based interface. Else, the GRUB screen is not displayed in console redirection. To disable the graphical interface, comment out the line starting with splashimage.
   • To start multiple GRUB options to start console sessions through the serial connection, add the following line to all options:

     console=ttyS1,57600

     The example shows console=ttyS1,57600 added to only the first option.
