Firewalls and default ports
|
|
===========================
|
|
|
|
On some deployments, such as ones where restrictive firewalls are in
|
|
place, you might need to manually configure a firewall to permit
|
|
OpenStack service traffic.
|
|
|
|
To manually configure a firewall, you must permit traffic through the
|
|
ports that each OpenStack service uses. This table lists the default
|
|
ports that each OpenStack service uses:
|
|

To function properly, some OpenStack components depend on other,
|
|
non-OpenStack services. For example, the OpenStack dashboard uses HTTP
|
|
for non-secure communication. In this case, you must configure the
|
|
firewall to allow traffic to and from HTTP.
|
|
|
|
This table lists the ports that other OpenStack components use:
|
|
|
|

On some deployments, the default port used by a service may fall within
|
|
the defined local port range of a host. To check a host's local port
|
|
range:
|
|
|
|
.. code-block:: console
|
|
|
|
$ sysctl net.ipv4.ip_local_port_range
|
|
|
|
If a service's default port falls within this range, run the following
|
|
program to check if the port has already been assigned to another
|
|
application:
|
|
|
|
.. code-block:: console
|
|
|
|
$ lsof -i :PORT
|
|
|
|
Configure the service to use a different port if the default port is
|
|
already being used by another application.
