Chapter 2. Installing VoltDB

VoltDB is available in both open source and commercial editions. The open source, or community, edition provides all the transactional performance benefits of VoltDB, plus basic durability and availability. The commercial editions provide additional features needed to support production environments, such as complete durability, dynamic scaling, and WAN replication.

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 6.6 or later, including 7.0 and later

  • Red Hat (RHEL) version 6.6 or later, including 7.0 and later

  • Ubuntu versions 14.04 and 16.04

Development builds are also available for Macintosh OS X 10.9 and later1.

Footnotes:

  1. CentOS 6.6, CentOS 7.0, RHEL 6.6, RHEL 7.0, and Ubuntu 14.04 and 16.04 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 10.9.

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

  3. 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.

  4. VoltDB supports JDKs from OpenJDK or Oracle/Sun.

  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.
