### Configure Redis Queues
#### Configure the Sentinel Cache nodes
NOTE: **Note:**
If you are using an external Redis Sentinel instance, be sure
to exclude the `requirepass` parameter from the Sentinel
configuration. This parameter will cause clients to report `NOAUTH
Authentication required.`. [Redis Sentinel 3.2.x does not support
password authentication](https://github.com/antirez/redis/issues/3279).
Now that the Redis servers are all set up, let's configure the Sentinel
servers. The following IPs will be used as an example:
- `10.6.0.71`: Sentinel - Cache 1
- `10.6.0.72`: Sentinel - Cache 2
- `10.6.0.73`: Sentinel - Cache 3
To configure the Sentinel Cache server:
1. SSH into the server that will host Consul/Sentinel.
1. [Download/install](https://about.gitlab.com/install/) the
Omnibus GitLab Enterprise Edition package using **steps 1 and 2** from the
GitLab downloads page.
- Make sure you select the correct Omnibus package, with the same version
the GitLab application is running.
- Do not complete any other steps on the download page.
1. Edit `/etc/gitlab/gitlab.rb` and add the contents:
```ruby
roles ['redis_sentinel_role']
## Must be the same in every sentinel node
redis['master_name'] = 'gitlab-redis-cache'
## The same password for Redis authentication you set up for the primary node.
redis['master_password'] = 'REDIS_PRIMARY_PASSWORD_OF_FIRST_CLUSTER'
## The IP of the primary Redis node.
redis['master_ip'] = '10.6.0.51'
## Define a port so Redis can listen for TCP requests which will allow other
## machines to connect to it.
redis['port'] = 6379
## Port of primary Redis server, uncomment to change to non default. Defaults
## to `6379`.
#redis['master_port'] = 6379
## Configure Sentinel's IP
sentinel['bind'] = '10.6.0.71'
## Port that Sentinel listens on, uncomment to change to non default. Defaults
## to `26379`.
#sentinel['port'] = 26379
## Quorum must reflect the amount of voting sentinels it take to start a failover.
## Value must NOT be greater then the amount of sentinels.
##
## The quorum can be used to tune Sentinel in two ways:
## 1. If a the quorum is set to a value smaller than the majority of Sentinels
## we deploy, we are basically making Sentinel more sensible to primary failures,
## triggering a failover as soon as even just a minority of Sentinels is no longer
## able to talk with the primary.
## 1. If a quorum is set to a value greater than the majority of Sentinels, we are
## making Sentinel able to failover only when there are a very large number (larger
## than majority) of well connected Sentinels which agree about the primary being down.s
sentinel['quorum'] = 2
## Consider unresponsive server down after x amount of ms.
#sentinel['down_after_milliseconds'] = 10000
## Specifies the failover timeout in milliseconds. It is used in many ways:
##
## - The time needed to re-start a failover after a previous failover was
## already tried against the same primary by a given Sentinel, is two
## times the failover timeout.
##
## - The time needed for a replica replicating to a wrong primary according
## to a Sentinel current configuration, to be forced to replicate
## with the right primary, is exactly the failover timeout (counting since
## the moment a Sentinel detected the misconfiguration).
##
## - The time needed to cancel a failover that is already in progress but
## did not produced any configuration change (REPLICAOF NO ONE yet not
## acknowledged by the promoted replica).
##
## - The maximum time a failover in progress waits for all the replica to be
## reconfigured as replicas of the new primary. However even after this time
## the replicas will be reconfigured by the Sentinels anyway, but not with
## the exact parallel-syncs progression as specified.
#sentinel['failover_timeout'] = 60000
## Enable service discovery for Prometheus
consul['enable'] = true
consul['monitoring_service_discovery'] = true
## The IPs of the Consul server nodes
## You can also use FQDNs and intermix them with IPs
consul['configuration'] = {
retry_join: %w(10.6.0.11 10.6.0.12 10.6.0.13),
}
# Set the network addresses that the exporters will listen on
node_exporter['listen_address'] = '0.0.0.0:9100'
redis_exporter['listen_address'] = '0.0.0.0:9121'
# Disable auto migrations
gitlab_rails['auto_migrate'] = false
```
1. To prevent database migrations from running on upgrade, run:
```shell
sudo touch /etc/gitlab/skip-auto-reconfigure
```
Only the primary GitLab application server should handle migrations.
1. [Reconfigure Omnibus GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
1. Go through the steps again for all the other Consul/Sentinel nodes, and
make sure you set up the correct IPs.
