# Manually install OS and system on servers

If you are not using the WMS or WSA automated tools for installing a WEKA cluster, manually install a supported OS and the WEKA software on the bare metal server.

{% hint style="info" %}
For optimal server performance and configuration, it is recommended to use the `bios_tool` to set BIOS settings on your servers.

Refer to the Appendix: [bios-tool](https://docs.weka.io/appendices/bios-tool "mention") for detailed instructions on using `bios_tool` to ensure that your servers meet the recommended BIOS configurations. Using this tool can significantly streamline the setup process and save time.

**Procedure**

1. Follow the relevant Linux documentation to install the operating system, including the required packages.

2. Install the WEKA software.
   * Once the WEKA software tarball is downloaded from [get.weka.io](https://get.weka.io), run the untar command.
   * Run the installation command on each server, following the instructions in the **Install** tab of [get.weka.io](https://get.weka.io/ui/dashboard).
   * (Optional) Enable safe shutdown:

     To ensure data integrity during server reboots or shutdowns, you can enable the safe shutdown feature during installation. This is highly recommended for converged servers.

     For instructions, see [safe-server-shutdown](https://docs.weka.io/planning-and-installation/bare-metal/manually-install-os-and-weka-on-servers/safe-server-shutdown "mention").

Once completed, the WEKA software is installed on all the allocated servers and runs in stem mode (no cluster is attached).

{% hint style="info" %}
If a failure occurs during the WEKA software installation process, an error message prompts detailing the source of the failure. Review the details and try to resolve the failure. If required, contact the [Customer Success Team](https://docs.weka.io/support/getting-support-for-your-weka-system#contact-customer-success-team).
