They guide you through: 1. Making your existing instance the **primary** node. 1. Adding **secondary** nodes. CAUTION: **Caution:** The steps below should be followed in the order they appear. **Make sure the GitLab version is the same on all nodes.** ## Using Omnibus GitLab If you installed GitLab using the Omnibus packages (highly recommended): 1. [Install GitLab Enterprise Edition](https://about.gitlab.com/install/) on the server that will serve as the **secondary** node. Do not create an account or log in to the new **secondary** node. 1. [Upload the GitLab License](../../../user/admin_area/license.md) on the **primary** node to unlock Geo. The license must be for [GitLab Premium](https://about.gitlab.com/pricing/) or higher. 1. [Set up the database replication](database.md) (`primary (read-write) <-> secondary (read-only)` topology). 1. [Configure fast lookup of authorized SSH keys in the database](../../operations/fast_ssh_key_lookup.md). This step is required and needs to be done on **both** the **primary** and **secondary** nodes. 1. [Configure GitLab](../replication/configuration.md) to set the **primary** and **secondary** nodes. 1. Optional: [Configure a secondary LDAP server](../../auth/ldap/index.md) for the **secondary** node. See [notes on LDAP](../index.md#ldap). 1. [Follow the "Using a Geo Server" guide](../replication/using_a_geo_server.md). ## Post-installation documentation After installing GitLab on the **secondary** nodes and performing the initial configuration, see the [following documentation for post-installation information](../index.md#post-installation-documentation).
