Configuring Redis for GitLab HA
You can choose to install and manage Redis yourself, or you can use GitLab Omnibus packages to help.
Configure your own Redis server
If you're hosting GitLab on a cloud provider, you can optionally use a managed service for Redis. For example, AWS offers a managed ElastiCache service that runs Redis.
Note: Redis does not require authentication by default. See Redis Security documentation for more information. We recommend using a combination of a Redis password and tight firewall rules to secure your Redis service.
Configure using Omnibus
-
Download/install GitLab Omnibus using steps 1 and 2 from GitLab downloads. Do not complete other steps on the download page.
-
Create/edit
/etc/gitlab/gitlab.rb
and use the following configuration. Be sure to change theexternal_url
to match your eventual GitLab front-end URL.external_url 'https://gitlab.example.com' # Disable all components except Redis redis['enable'] = true bootstrap['enable'] = false nginx['enable'] = false unicorn['enable'] = false sidekiq['enable'] = false postgresql['enable'] = false gitlab_workhorse['enable'] = false mailroom['enable'] = false # Redis configuration redis['port'] = 6379 redis['bind'] = '0.0.0.0' # If you wish to use Redis authentication (recommended) redis['password'] = 'Redis Password'

Run
sudo gitlab-ctl reconfigure
to install and configure PostgreSQL.Note
: This
reconfigure
step will result in some errors. That's OK - don't be alarmed. -
Run
touch /etc/gitlab/skip-auto-migrations
to prevent database migrations from running on upgrade. Only the primary GitLab application server should handle migrations.
