After installing the operating system on each node for the architecture that you choose to deploy, you must configure the network interfaces. We recommend that you disable any automated network management tools and manually edit the appropriate configuration files for your distribution. For more information on how to configure networking on your distribution, see the documentation.
To disable NetworkManager
and enable the network
service:
# service NetworkManager stop # service network start # chkconfig NetworkManager off # chkconfig network on
RHEL and derivatives including CentOS and Scientific Linux enable a restrictive firewall by default. During this installation, certain steps will fail unless you alter or disable the firewall. For further information about securing your installation, refer to the OpenStack Security Guide.
On Fedora, firewalld replaces
iptables as the default firewall system. While you
can use firewalld successfully, this guide
references iptables for compatibility with other
distributions.
To disable firewalld and enable
iptables:
# service firewalld stop # service iptables start # chkconfig firewalld off # chkconfig iptables on
Proceed to network configuration for the example OpenStack Networking (neutron) or legacy networking (nova-network) architecture.
