Hardware

HardwareGood to know

Architecture

x86-64

CPU

2+ cores

Memory:

3+ GB

  • You'll need at least 3GB available memory. We recommend 1GB for Bitbucket and an additional 2GB to support Git operations. 
  • Your specific hardware requirements will depend on the number and frequency of Git operations and the number of active users. See Scaling Bitbucket Server for more information. 
  • For setting up Bitbucket Mesh, see requirements for Mesh nodes.

Environments

EnvironmentsGood to know

(tick) Linux

(info) Apple macOS

  • In production environments Bitbucket should be run from a dedicated user account.
  • Linux support requires a 2.6.17+ kernel and glibc 2.7+. This means that Red Hat Enterprise Linux 5, which uses glibc 2.5, is no longer supported for Bitbucket Server 7.0+. 

Known issues

  • You can’t use NFS hosted on Windows for Bitbucket’s shared home directory.
  • Apple macOS is evaluation only. MacOS cannot be used for production deployment.

  • Bitbucket will install a supported version of AdoptiumOpenJDK Java JRE that is only available to Bitbucket if necessary. See Running the Bitbucket installer.

  • If you choose to pre-install a JRE, we recommend using Adoptium OpenJDK's (formerly known as AdoptOpenJDK) Java 8 JRE, which you can download from the AdoptOpenJDK website.

  • For OpenJDK, download and install instructions for Linux flavors at http://openjdk.java.net/install/.

  • Pre-installed Java on some AWS EC2 Linux instances might be installed with a subset of features. For more information, see SSH server fails to start on AWS EC2 instance.

  • We support standard OpenJDK builds, including Oracle's official build, alternative builds such as Adoptium OpenJDK (formerly known as AdoptOpenJDK), and builds shipped with Linux distributions such as Red Hat Enterprise. 

  • AdoptOpenJDK is now known as AdoptiumOpenJDK.
  • Oracle Java 8u311 and 8u321 are not supported due to JDK-8279618.
