How can I restart bundle nginx in gitlab separately?

Question

I have installed Gitlab CE version. I can find nginx bundled in Gitlab. However I cannot find a way to restart nginx separately. I have tried sudo service nginx restart but it gives:

* Restarting nginx nginx                                     [fail] 

I have checked all the document but cannot find a solution. I am trying to add vhost to the bundled nginx according to this tutorial. But I stuck at that step. Is there other way to add vhost to bundled nginx with Gitlab? Or How can I check whether my nginx conf work?

Edit: 502 error I have solved.

I try to use NON-bundle nginx according to this doc , But after I modify gitlab.rb and run sudo gitlab-ctl reconfigure , I got 502 Whoops, GitLab is taking too much time to respond. error.

Here is my gitlab.conf for nginx.

upstream gitlab {
  server unix://var/opt/gitlab/gitlab-git-http-server/sockets/gitlab.socket fail_timeout=0;
  #
}

server {
  listen *:80;
  server_name blcu.tk;
  server_tokens off;
  root /opt/gitlab/embedded/service/gitlab-rails/public;

  client_max_body_size 250m;

  access_log  /var/log/gitlab/nginx/gitlab_access.log;
  error_log   /var/log/gitlab/nginx/gitlab_error.log;

To restart only one component of GitLab Omnibus you can execute sudo gitlab-ctl restart <component>. Therefore, to restart Nginx:

sudo gitlab-ctl restart nginx

As a further note, this same concept is possible with nearly all of the gitlab-ctl commands. For example, sudo gitlab-ctl tail allows you to see all GitLab logs. Applying this concept, sudo gitlab-ctl tail nginx will tail only Nginx logs.
