Configuring the TFTP Server

If you get the “Permission denied” error when trying to connect to the TFTP server from the client server, try running # restorecon -Rv /tftboot/ on the TFTP server.

Configuring TFTP Server for Installation on BIOS-based Client Servers

To configure the TFTP server for installation on BIOS-based client servers, do the following:

Make sure the TFTP server, Xinetd, and SYSLINUX bootloader are installed:
1
# yum install tftp-server syslinux xinetd

Edit the /etc/xinetd.d/tftp file to have the following:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
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
}

Copy the following files to the /tftpboot directory (if this directory does not exist, create it under the root (/) directory):
- /images/pxeboot/vmlinuz and /images/pxeboot/initrd.img from the Virtuozzo Server distribution,
- menu.c32 and pxelinux.0 from the syslinux directory (usually /usr/share/syslinux or /usr/lib/syslinux).
In the /tftpboot directory, create the /pxelinux.cfg directory. In it, create the file default.

Add the following lines to /tftpboot/pxelinux.cfg/default:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
default menu.c32
prompt 0
timeout 60
ontimeout VZ
menu title Virtuozzo Server Boot Menu
label 1
    menu label Install Virtuozzo Server 7 with GUI management
    kernel vmlinuz
    append initrd=initrd.img ui ip=dhcp inst.repo=http://<HTTP_server_IP_address>/vz
label 2
    menu label Install Virtuozzo Server 7 with CLI management
    kernel vmlinuz
    append initrd=initrd.img ip=dhcp inst.repo=http://<HTTP_server_IP_address>/vz

For more details on the parameters you can specify in /tftpboot/pxelinux.cfg/default, see the documentation for syslinux.

Start the xinetd service:

1
# systemctl start xinetd.service

Or restart it if already running:

1
# systemctl restart xinetd.service

If necessary, allow incoming connections to the TFTP service in the firewall:

1
2
# firewall-cmd --add-service=tftp --permanent
# systemctl restart firewalld.service

Configuring TFTP Server for Installation on EFI-based Client Servers

To configure the TFTP server for installation on EFI-based client servers, do the following:

Make sure the TFTP server and Xinetd are installed:
1
# yum install tftp-server xinetd

Edit the /etc/xinetd.d/tftp file to have the following:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
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
}

Copy the following files from the Virtuozzo Server distribution to the /tftpboot directory (if this directory does not exist, create it under the root (/) directory):
- /images/pxeboot/vmlinuz,
- /images/pxeboot/initrd.img,
- /EFI/BOOT/grubx64.efi.
In the /tftpboot directory, create the grub.cfg file.

Add the following lines to /tftpboot/grub.cfg:

1
2
3
4
5
6
7
8
9
set timeout=60
    menuentry 'Virtuozzo Server 7 with GUI management' {
    linuxefi vmlinuz ui ip=dhcp inst.repo=http://<HTTP_server_IP_address>/vz
    initrdefi initrd.img
}
    menuentry 'Virtuozzo Server 7 with CLI management' {
    linuxefi vmlinuz ip=dhcp inst.repo=http://<HTTP_server_IP_address>/vz
    initrdefi initrd.img
}

Start the xinetd service:

1
# systemctl start xinetd.service

Or restart it if already running:

1
# systemctl restart xinetd.service

If necessary, allow incoming connections to the TFTP service in the firewall:

1
2
# firewall-cmd --add-service=tftp --permanent
# systemctl restart firewalld.service
