In this configuration, Redis is not scaled, and represents a single point of failure. However, in a scaled environment the objective is to allow the environment to handle more users or to increase throughput. Redis itself is generally stable and can handle many requests, so it is an acceptable trade off to have only a single instance. See the [reference architectures](../reference_architectures/index.md) page for an overview of GitLab scaling options. ## Set up the standalone Redis instance The steps below are the minimum necessary to configure a Redis server with Omnibus GitLab: 1. SSH into the Redis server. 1. [Download and install](https://about.gitlab.com/install/) the Omnibus GitLab package you want by using **steps 1 and 2** from the GitLab downloads page. Do not complete any other steps on the download page. 1. Edit `/etc/gitlab/gitlab.rb` and add the contents: ```ruby ## Enable Redis and disable all other services ## https://docs.gitlab.com/omnibus/roles/ roles ['redis_master_role'] ## Redis configuration redis['bind'] = '0.0.0.0' redis['port'] = 6379 redis['password'] = '' ## Disable automatic database migrations ## Only the primary GitLab application server should handle migrations gitlab_rails['auto_migrate'] = false ``` 1. [Reconfigure Omnibus GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect. 1. Note the Redis node's IP address or hostname, port, and Redis password. These are necessary when [configuring the GitLab application servers](#set-up-the-gitlab-rails-application-instance). [Advanced configuration options](https://docs.gitlab.com/omnibus/settings/redis.html) are supported and can be added if needed. ## Set up the GitLab Rails application instance On the instance where GitLab is installed: 1. Edit the `/etc/gitlab/gitlab.rb` file and add the following contents: ```ruby ## Disable Redis redis['enable'] = false gitlab_rails['redis_host'] = 'redis.example.com' gitlab_rails['redis_port'] = 6379 ## Required if Redis authentication is configured on the Redis node gitlab_rails['redis_password'] = '' ``` 1. Save your changes to `/etc/gitlab/gitlab.rb`. 1. [Reconfigure Omnibus GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect. ## Troubleshooting See the [Redis troubleshooting guide](troubleshooting.md).
