my gitlab configure /etc/gitlab/gitlab.rb:

external_url 'http://gitlab.ifbuyer.com'
nginx['enable'] = false
unicorn['enable'] = false
web_server['external_users'] = ['nginx']
gitlab_rails['internal_api_url'] = 'http://gitlab.ifbuyer.com'
nginx['redirect_http_to_https'] = true

my gitlab.ifbuyer.com.conf is followed by the link https://docs.gitlab.com/omnibus/settings/nginx.html#using-an-existing-passenger-nginx-installation

I am using gitlab-ce-9.5.0-ce.0.el7.x86_64

Any help would be appreciated. Thanks you so much

You should try and run Gitlab using docker, that will help you focus on just the nginx part

You can instal docker and docker-compose using below script

curl -SsL https://get.docker.com | sh
pip install docker-compose

Then create a folder for gitlab and create a docker-compose.yml file

docker-compose.yml

version: '3'
services:
  gitlab:
    image: gitlab/gitlab-ce:${GITLAB_VERSION}
    hostname: gitlab.example.com
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'https://gitlab.example.com'
        gitlab_rails['gitlab_shell_ssh_port'] = 22
    ports:
      - "22:22"
      - "80:80"
      - "443:443"
    volumes:
      - ./config:/etc/gitlab
      - ./logs:/var/log/gitlab
      - ./data:/var/opt/gitlab
      - ./scrtips:/scripts

Latest GITLAB_VERSION is 9.5.2-ce.0. So you can either replace it in file or export that before running the above using below commands

$ GITLAB_VERSION='9.5.2-ce.0' docker-compose up

Once the server is up it will be accessible at gitlab.example.com, either make a host entry or use IP in config. Then you can proxy_pass it from your nginx.
