2.3. Configuring the TFTP Server¶

In the next step, you need to configure the TFTP server that you installed in the previous step. This section describes the process of configuring the TFTP server for BIOS-based systems. For information on how to configure the TFTP server for installing Acronis Storage on EFI-based systems, see the Red Hat Enterprise Linux Installation Guide.

To configure the TFTP server:

1. On the PXE server, open the /etc/xinetd.d/tftp file, and edit it as follows:

   service tftp
   {
   disable         = no
   socket_type     = dgram
   protocol        = udp
   wait            = yes
   user            = root
   server          = /usr/sbin/in.tftpd
   server_args     = -v -s /tftpboot
   per_source      = 11
   cps             = 100 2
   flags           = IPv4
   }
   

   Once you are done, save the file.

2. Copy the following files to the /tftpboot directory (if this directory does not exist, create it under the root (/) directory):

   • vmlinuz
   • initrd.img
   • menu.c32
   • pxelinux.0

   These files are necessary to start the installation of Acronis Storage. You can find the first two files in the /images/pxeboot directory of the Acronis Storage distribution. The menu.c32 and pxelinux.0 files are located in the syslinux installation directory on the PXE server (usually, this is the /usr/share/syslinux or /usr/lib/syslinux directory).

3. Create the /tftpboot/pxelinux.cfg directory, and inside this directory, make the default file.

4. Open the default file for editing, and add the following strings to it:

   default menu.c32
   prompt 0
   timeout 100
   ontimeout VZ
   menu title Boot Menu
   label VZ
           menu label Install
           kernel vmlinuz
           append initrd=initrd.img ip=dhcp
   

   For detailed information on the parameters you can specify in the /tftpboot/pxelinux.cfg/default file and their configuration, see the documentation for syslinux and its man pages.

5. Restart the xinetd service:

   # /etc/init.d/xinetd restart
   

6. If necessary, configure your firewall on the PXE server to allow access to the TFTP server.

   Note

   When running the TFTP server, you might get the “Permission denied” error. In this case, you may try to fix the problem by running the following command on the server: # restorecon -Rv /tftboot/.
