Unicorn settings
Starting with GitLab 13.0, Puma is the default web server and Unicorn has been
disabled by default.
Enabling Unicorn
To use Unicorn instead of Puma, add the following to /etc/gitlab/gitlab.rb and
run sudo gitlab-ctl reconfigure
puma['enable'] = false
unicorn['enable'] = true
Adjusting workers or timeout
If you need to adjust the Unicorn timeout or the number of workers you can use
the following settings in /etc/gitlab/gitlab.rb.
Run sudo gitlab-ctl reconfigure for the change to take effect.
unicorn['worker_processes'] = 3
unicorn['worker_timeout'] = 60
Minimum required
worker_processes is 2 in order for the web editor to work correctly, see GitLab issue #14546 for details.
Be sure to review recommended number of Unicorn Workers
before changing.
