For Linux deployments, 64-bit Linux-based OS is required. The following table shows the Linux distributions supported along with the corresponding minimum supported version. Composer Server also uses Java, PostgreSQL, and Spark. Ensure that the appropriate version of these tools are used in the deployment of Composer in your operating environment.
|CentOS||6.x, 7, & 8|
|Red Hat||6.x, 7, & 8|
|Ubuntu||16.04 LTS, 18|
|Java||11.0.5 (or later)|
Important CentOS 6 Information
Support for CentOS 6 will be deprecated when it is no longer supported by Red Hat Enterprise Linux (RHEL).
If your environment is running CentOS6, a special installation Bootstrap procedure, called
bootstrap-zoomdata-centos6.run, must be used to install or upgrade to Composer 5.9 or later. The regular Bootstrap procedure will fail in CentOS 6 environments.
In addition, if your environment is running CentOS 6, you must manually install OpenJDK 11. OpenJDK 11 is available from various vendors, such as AWS Corretto, OpenJDK11, or Oracle JDK11. See Manually Installing OpenJDK 11.
When you attempt to install or upgrade Composer in a CentOS 6 environment that does not have OpenJDK 11 installed, the installation script will start, but will produce FAIL messages during its execution because of the missing OpenJDK 11 software. When the installation script runs, the Composer binaries are upgraded to the latest version, but you will not be able to start Composer without first manually installing OpenJDK 11.
Important Ubuntu Information
Ubuntu users who have Composer or Zoomdata versions earlier than 5.8 installed must first remove the legacy repository before upgrading Composer 5.8 or later. Use this command:
sudo rm -f /etc/apt/sources.list.d/saltstack.list
For RPM and Ubuntu installations, the following server specifications are recommended:
- 64 GB RAM (minimum is 16 GB)
- 500 GB disk space
- 16 cores

Composer uses a packaged PostgreSQL v12 database instance to store its metadata and strongly recommends using this instance due to the specific configuration and version employed. If you would like to use another PostgreSQL instance, contact Technical Support for further guidance.

Composer recommends installing the Network Time Protocol daemon (NTPD) to allow for time synchronization of networked servers to Coordinated Universal Time (UTC), if not already available in your network. See Using the Network Time Protocol to Synchronize Time for guidance.
