The Cassandra PV Archiver server is provided in two forms of distribution: The first one is a binary archive that can be used on Windows and most Unix-like platforms. The second one comes in the form of a Debian package. This Debian package has been designed to work on Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Most likely it is also going to work on most other modern, Debian-based distributions, as long as they use Upstart or systemd. The Debian package does not provide a traditional System-V style init script, so it will not work on distributions using this kind of init system.
When installing the Debian package, the package scripts take
care of
creating a user and group with the names
cassandra-pv-archiver
and registering the server with
the init system.
This means that
after installing the package, the
cassandra-pv-archiver-server
job is automatically
started with the privileges of that user.
When using the binary distribution, users have to take care of manually creating a user and group for running the server and also have to register the server with their init system. It is possible to run the the server as an existing user or even as the root user, but for a production setup, using a separate user is strongly encouraged for security reasons.
When using the binary distribution (and not the Debian package),
the
start script for running the archive server is located in the
bin
directory and is called
cassandra-pv-archiver-server
(
cassandra-pv-archiver-server.bat
on Windows).
The server runs in the foreground, so the terminal
that is running the
server has to be kept alive.
When installing the Cassandra PV Archiver for the first time,
the
keyspace used for storing data has to be created in the
Cassandra
cluster.
The default name for the keyspace is
pv_archive
.
You can choose a different name, but in this case the name has
to be
explicitly specified in the configuration file of the
Cassandra PV
Archiver server.
In order to create the
pv_archive
keyspace in a
single node cluster, you can run the following
command in the CQL shell
(
cqlsh
):
CREATE KEYSPACE pv_archive WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'};
When using a multi-node cluster, you typically do not want to
use the
SimpleStrategy
for replication and the replication
factor should be at least
three.
Please refer to the
Cassandra documentation
provided by DataStax for details.

When enabling authentication for the Cassandra cluster, ensure that the user used for the Cassandra PV Archiver server has full write access to its keyspace. In particular, it has to be able to create tables and query and modify data.
For this purpose, the user at least needs the

When using a local, single-node Cassandra setup with the default keyspace name and not requiring authentication, the default configuration should be fine for getting started. Otherwise, please refer to Section 3, “Server configuration” .
Once the server has been started, its administrative web-interface is available on port 4812 (unless the port number has been changed in the configuration file). Please refer to Section 4, “Administrative user interface” to learn more about using the administrative interface.
