Chapter 2. Installing VoltDB

VoltDB is available in both an open source and an enterprise edition. The open source, or community, edition provides basic database functionality with all the transactional performance benefits of VoltDB. The enterprise edition provides additional features needed to support production environments, such as high availability, durability, and dynamic scaling and schema management.

Depending on which version you choose, the VoltDB software comes as either pre-built distributions or as source code. This chapter explains the system requirements for running VoltDB, how to install and upgrade the software, and what resources are provided in the kit.

2.1. Operating System and Software Requirements

The following are the requirements for developing and running VoltDB applications.

Table 2.1. Operating System and Software Requirements

Operating System

VoltDB requires a 64-bit Linux-based operating system. Kits are built and qualified on the following platforms:

  • CentOS version 6.3 or later, including 7.0

  • Red Hat (RHEL) version 6.3 or later, including 7.0

  • Ubuntu versions 10.042, 12.04, and 14.04

Development builds are also available for Macintosh OS X 10.7 and later1.
CPU

  • Dual core3 x86_64 processor

  • 64 bit

  • 1.6 GHz

Memory4 Gbytes4
Java

Java 7 or 8 — VoltDB supports JDKs from OpenJDK or Oracle/Sun

Required Software

NTP5

Python 2.5 or later release of 2.x

Recommended Software

Eclipse 3.x (or other Java IDE)

Footnotes:

  1. CentOS 6.3, CentOS 7.0, RHEL 6.3, RHEL 7.0, and Ubuntu 10.04, 12.04, and 14.04 are the only officially supported operating systems for VoltDB. However, VoltDB is tested on several other POSIX-compliant and Linux-based 64-bit operating systems, including Macintosh OS X 10.7.

  2. Support for Ubuntu 10.04 is deprecated and will be removed in an upcoming release.

  3. Dual core processors are a minimum requirement. Four or eight physical cores are recommended for optimal performance.

  4. Memory requirements are very specific to the storage needs of the application and the number of nodes in the cluster. However, 4 Gigabytes should be considered a minimum configuration.

  5. NTP minimizes time differences between nodes in a database cluster, which is critical for VoltDB. All nodes of the cluster should be configured to synchronize against the same NTP server. Using a single local NTP server is recommended, but not required.
