HTTP Frontends

|
|
|
|
The Ceph Object Gateway supports two embedded HTTP frontend libraries
|
|
that can be configured with ``rgw_frontends``. See `Config Reference`_
|
|
for details about the syntax.
|
|
|
|
Beast
|
|
=====
|
|
|
|
.. versionadded:: Mimic
|
|
|
|
The ``beast`` frontend uses the Boost.Beast library for HTTP parsing
|
|
and the Boost.Asio library for asynchronous network i/o.
|
|
|
|
Options
|
|
-------
|
|
|
|
``port`` and ``ssl_port``
|
|
|
|
:Description: Sets the ipv4 & ipv6 listening port number. Can be specified multiple
|
|
times as in ``port=80 port=8000``.
|
|
:Type: Integer
|
|
:Default: ``80``
|
|
|
|
|
|
``endpoint`` and ``ssl_endpoint``
|
|
|
|
:Description: Sets the listening address in the form ``address[:port]``, where
|
|
the address is an IPv4 address string in dotted decimal form, or
|
|
an IPv6 address in hexadecimal notation surrounded by square
|
|
brackets. Specifying a IPv6 endpoint would listen to v6 only. The
|
|
optional port defaults to 80 for ``endpoint`` and 443 for
|
|
``ssl_endpoint``. Can be specified multiple times as in
|
|
``endpoint=[::1] endpoint=192.168.0.100:8000``.
|
|
|
|
:Type: Integer
|
|
:Default: None
|
|
|
|
|
|
``ssl_certificate``
|
|
|
|
:Description: Path to the SSL certificate file used for SSL-enabled endpoints.
|
|
If path is prefixed with ``config://``, the certificate will be
|
|
pulled from the ceph monitor ``config-key`` database.
|
|
|
|
:Type: String
|
|
:Default: None
|
|
|
|
|
|
``ssl_private_key``
|
|
|
|
:Description: Optional path to the private key file used for SSL-enabled
|
|
endpoints. If one is not given, the ``ssl_certificate`` file
|
|
is used as the private key.
|
|
If path is prefixed with ``config://``, the certificate will be
|
|
pulled from the ceph monitor ``config-key`` database.
|
|
|
|
:Type: String
|
|
:Default: None
|
|
|
|
``tcp_nodelay``
|
|
|
|
:Description: If set the socket option will disable Nagle's algorithm on
|
|
the connection which means that packets will be sent as soon
|
|
as possible instead of waiting for a full buffer or timeout to occur.
|
|
|
|
``1`` Disable Nagel's algorithm for all sockets.
|
|
|
|
``0`` Keep the default: Nagel's algorithm enabled.
|
|
|
|
:Type: Integer (0 or 1)
|
|
:Default: 0
|
|
|
|
``max_connection_backlog``
|
|
|
|
:Description: Optional value to define the maximum size for the queue of
|
|
connections waiting to be accepted. If not configured, the value
|
|
from ``boost::asio::socket_base::max_connections`` will be used.
|
|
|
|
:Type: Integer
|
|
:Default: None
|
|
|
|
|
|
Civetweb
|
|
========
|
|
|
|
.. versionadded:: Firefly
|
|
|
|
The ``civetweb`` frontend uses the Civetweb HTTP library, which is a
|
|
fork of Mongoose.
|
|
|
|
|
|
Options
|
|
-------
|
|
|
|
``port``
|
|
|
|
:Description: Sets the listening port number. For SSL-enabled ports, add an
|
|
``s`` suffix like ``443s``. To bind a specific IPv4 or IPv6
|
|
address, use the form ``address:port``. Multiple endpoints
|
|
can either be separated by ``+`` as in ``127.0.0.1:8000+443s``,
|
|
or by providing multiple options as in ``port=8000 port=443s``.
|
|
|
|
:Type: String
|
|
:Default: ``7480``
|
|
|
|
|
|
``num_threads``
|
|
|
|
:Description: Sets the number of threads spawned by Civetweb to handle
|
|
incoming HTTP connections. This effectively limits the number
|
|
of concurrent connections that the frontend can service.
|
|
|
|
:Type: Integer
|
|
:Default: ``rgw_thread_pool_size``
|
|
|
|
|
|
``request_timeout_ms``
|
|
|
|
:Description: The amount of time in milliseconds that Civetweb will wait
|
|
for more incoming data before giving up.
|
|
|
|
:Type: Integer
|
|
:Default: ``30000``
|
|
|
|
|
|
``ssl_certificate``
|
|
|
|
:Description: Path to the SSL certificate file used for SSL-enabled ports.
|
|
|
|
:Type: String
|
|
:Default: None
|
|
|
|
``access_log_file``
|
|
|
|
:Description: Path to a file for access logs. Either full path, or relative
|
|
to the current working directory. If absent (default), then
|
|
accesses are not logged.
|
|
|
|
:Type: String
|
|
:Default: ``EMPTY``
|
|
|
|
|
|
``error_log_file``
|
|
|
|
:Description: Path to a file for error logs. Either full path, or relative
|
|
to the current working directory. If absent (default), then
|
|
errors are not logged.
|
|
|
|
:Type: String
|
|
:Default: ``EMPTY``
|
|
|
|
|
|
The following is an example of the ``/etc/ceph/ceph.conf`` file with some of these options set: ::
|
|
|
|
[client.rgw.gateway-node1]
|
|
rgw_frontends = civetweb request_timeout_ms=30000 error_log_file=/var/log/radosgw/civetweb.error.log access_log_file=/var/log/radosgw/civetweb.access.log
|
|
|
|
A complete list of supported options can be found in the `Civetweb User Manual`_.

|
Generic Options
|
|
===============
|
|
|
|
Some frontend options are generic and supported by all frontends:
|
|
|
|
``prefix``
|
|
|
|
:Description: A prefix string that is inserted into the URI of all
|
|
requests. For example, a swift-only frontend could supply
|
|
a uri prefix of ``/swift``.
|
|
|
|
:Type: String
|
|
:Default: None
