Install AlloyDB Omni on Debian or Ubuntu

This section shows you how to install AlloyDB Omni using the AlloyDB Omni CLI in your Debian or Ubuntu environment.

System requirements

Ensure that you have a Linux machine that meets the following system requirements:

• A virtual or physical machine running a Debian-based OS, such as Debian or Ubuntu.
• A minimum of 2 CPUs, with x86/AMD64 architecture.
• A minimum of 2 GB of RAM. For optimal performance, we recommend allocating 8 GB of RAM for each CPU.
• At least 20 GB of available storage.
• Unrestricted root access within the OS.
• Linux kernel version 4.18 or higher. We recommend kernel version 5.3 or higher for best performance.
• Linux cgroup v2 enabled.

  By default, cgroup v2 is enabled on most modern Linux systems. To check whether cgroup v2 is enabled, run stat -fc %T /sys/fs/cgroup/ in a shell. If cgroup v2 is enabled, the command output shows cgroup2fs.

• TCP port 5432 not in use by any other service.
• If you are installing AlloyDB Omni on a cloud platform, then we recommend using the following instance types:
• On Google Cloud, we recommend n2-highmem instances.
• On Amazon Web Services, we recommend R6i instances.
• On Microsoft Azure, we recommend Ebsv5 instances.
