Installation Using PXE

2.4. Setting Up a DHCP Server

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/.

2.4 Setting Up a DHCP Server

Now you can proceed with conﬁguring a DHCP server. To conﬁgure the DHCP server for installing Acronis

Storage over the network, open the dhcpd.conf ﬁle (usually, it is located in the /etc or /etc/dhcp directory) for

editing and add the following strings to this ﬁle:

next-server <PXE_server_IP_address>;

filename ”/pxelinux.0”;

Note: To conﬁgure a DHCP server for installation on EFI-based systems, specify filename ”/bootx64.efi”

instead of filename ”/pxelinux.0” in the dhcpd.conf ﬁle (where /bootx64.efi is the directory to which you copied

the EFI boot images when setting up the TFTP server).

2.5 Setting Up an HTTP Server

Now that you have set up the TFTP and DHCP servers, you need to make the Acronis Storage distribution ﬁles

available for installation over the network. To do this:

1. Set up an HTTP server. You can also use an existing HTTP server, if you have one.

2. Copy the contents of your Acronis Storage installation DVD to some directory on the HTTP server (e.g.,

/var/www/html/astor).

3. On the PXE server, open the /tftpboot/pxelinux.cfg/default ﬁle for editing, and specify the path to the Acronis

Storage installation ﬁles on the HTTP server.
