How to setup Gitlab-omnibus with non-bundled web-server?

Solution 1:

Continuing to explore I find the /var/opt/gitlab/ directory and solve this doing:

sudo ln -s /var/opt/gitlab/nginx/conf/gitlab-http.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-{available,enabled}/gitlab-http.conf
sudo service nginx reload

Solution 2:

As for gitlab 8, we cannot symlink to the default gitlab-http.conf anymore because the bundle webserver will not be installed when we set nginx['enable'] = false.

Just download the right web server configs from GitLab recipes repository and change YOUR_SERVER_FQDN with your preferred domain name.
