I’ve been trying to get this sorted all day. I’m running an omnibus install of GitLab on Ubuntu 14.04, using an existing nginx install. I can login, create projects, issues, etc. but I cannot push/pull, clone or anything to a project from the outside (not through web gui). One catch…I’m running Plesk 12.5 on this server. Here’s some outputs:

Error being reported by nginx:

2016/02/10 16:00:50 [crit] 24866#0: *53 connect() to unix://var/opt/gitlab/gitlab-workhorse/socket 
failed (13: Permission denied) while connecting to upstream, client: XXX.XXX.X.X, 
server: git.example.com, 
request: "GET /namespace/project-name.git/info/refs?service=git-upload-pack HTTP/1.1", 
upstream: "http://unix://var/opt/gitlab/gitlab-workhorse/socket:/namespace/project-name.git/info/refs?service=git-upload-pack", host: "git.example.com"

The permissions on the workhorse socket:

srwxrwxrwx 1 git git 0 Feb 2 18:40 socket

I’ve tried to change the owner to nginx (www-data) and the group to gitlab-www but no luck. I’m not using any different directories….just not sure where to go from here. I’m so close to getting this running yet feel so far!!

Gitlab:check (yes there’s an error in the IMAP settings, but I wouldn’t think that is related???)

Here’s the nginx configuration for the vhost:

    try_files $uri $uri/index.html $uri.html @gitlab;
}

error_page 502 /502.html;

Lastly, here’s the configuration at the server block level for the vhost:

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

upstream gitlab-workhorse {
  server unix://var/opt/gitlab/gitlab-workhorse/socket fail_timeout=0;
}

Looking over the docs at https://github.com/gitlabhq/omnibus-gitlab/blob/master/doc/settings/nginx.md I see this note but it doesn’t specify what the permissions should be:

*Note: make sure that the webserver user has the correct permissions on all directories used by external web-server, otherwise you will receive failed (XX: Permission denied) while reading upstream errors.

Any guidance would be much appreciated.

  1. The same problem happened to my server. And I solved by edit /etc/gitlab/gitlab.rc

        # my nginx run with user nginx.
        web_server['external_users'] = ['nginx']
        web_server['username'] = 'nginx'
        web_server['group'] = 'nginx'
        web_server['uid'] = 994 
        web_server['gid'] = 991 
        web_server['shell'] = '/bin/false'                                                                                                                                                                                  
        web_server['home'] = '/var/lib/nginx'
    

    At first time I just add web_server[‘external_users’] = [‘nginx’] but it still not work untill I add these all. May this help to you.

  2. Had encountered similar issue, and the log clearly suggested permission issues.

    At the end of the documentation from Gitlab for NGINX configuration, http://doc.gitlab.com/omnibus/settings/nginx.html it provides the required permission settings.
    sudo usermod -aG gitlab-www www-data
    after restarting the services it worked as expected.

  3. Strangely no user was defined in my /etc/nginx/nginx.conf file and this was causing the problem you mentioned.

    So I added this line in the /etc/nginx/nginx.conf file:

    user www-data;
    

    And then I ran this command:

    sudo usermod -aG gitlab-www www-data
    

    I restarted Nginx (sudo service nginx restart) and everything went fine.
