7.4. Configuring DHCP and Host Name Resolution

This section describes how to perform system-wide network configurations on the broker. Note that no new packages are required to complete this configuration.

Note

This section assumes that the broker is using the eth0 network interface. If your system uses a different interface, substitute that interface name in the file names in the ensuing instructions.

7.4.1. Configuring the DHCP Client on the Broker Host

For correct configuration, ensure the DHCP client uses the local BIND instance, and the correct host name and domain name.
Use the following procedure to configure the DHCP client correctly. Remember to replace the example IP addresses, host names, and domain names with the values to suit your environment.

Procedure 7.8. To Configure DHCP on the Broker Host:

  1. Create the /etc/dhcp/dhclient-eth0.conf file: 
    # touch /etc/dhcp/dhclient-eth0.conf
    Copy to Clipboard Toggle word wrap
  2. Edit the file to contain the following lines: 
    prepend domain-name-servers 10.0.0.1;
prepend domain-search "example.com";
    Copy to Clipboard Toggle word wrap
  3. Open the /etc/sysconfig/network file. Locate the line that begins with HOSTNAME= and ensure it is set to your broker host name: 
    HOSTNAME=broker.example.com
    Copy to Clipboard Toggle word wrap
  4. Run the following command to immediately set the host name. Remember to replace the example value with the fully-qualified domain name of your broker host. 
    # hostname broker.example.com
    Copy to Clipboard Toggle word wrap

Note

If you use the kickstart or bash script, the configure_dns_resolution and configure_hostname functions perform these steps.
