当我用sudo gitlab-ctl restart（Debian杰西）重启gitlab服务器时，服务器正在加载，我得到了502错误，而不是“部署”页面。然后一切都正常。我不明白为什么会发生这种情况。

请注意，只有在加载时才会显示此信息，然后一切正常。我不满意，因为我以前得到的“部署”页面更好。

这是在我配置gitlab通过gitlab-workhorse来运行apache服务器代理后发生的（在此之前，我的web界面通信出现了很大的问题。快照下载无法正常工作，但现在一切都很好）。在修复这个问题之前，我使用gitlab的nginx代理。
我目前使用的apache配置如下，它符合standard configuration of Gitlab：

<VirtualHost *:443>
  ServerName git.example.com
  ServerSignature Off

  ProxyPreserveHost On

  # Ensure that encoded slashes are not decoded but left in their encoded state.
  # http://doc.gitlab.com/ce/api/projects.html#get-single-project
  AllowEncodedSlashes NoDecode

  <Location />
    # New authorization commands for apache 2.4 and up
    # http://httpd.apache.org/docs/2.4/upgrading.html#access
    Require all granted

    #Allow forwarding to gitlab-workhorse
    ProxyPassReverse http://127.0.0.1:8283
    ProxyPassReverse https://git.example.com/

  </Location>

  RewriteEngine on

  #Don't escape encoded characters in api requests
  RewriteCond %{REQUEST_URI} ^/api/v3/.*
  RewriteRule .* http://127.0.0.1:8283%{REQUEST_URI} [P,QSA,NE]

  #Forward all requests to gitlab-workhorse except existing files like error documents
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f [OR]
  RewriteCond %{REQUEST_URI} ^/uploads/.*
  RewriteRule .* http://127.0.0.1:8283%{REQUEST_URI} [P,QSA]

  # needed for downloading attachments
  DocumentRoot /opt/gitlab/embedded/service/gitlab-rails/public

  #Set up apache error documents, if back end goes down (i.e. 503 error) then a maintenance/deploy page is thrown up.
  ErrorDocument 404 /404.html
  ErrorDocument 422 /422.html
  ErrorDocument 500 /500.html
  ErrorDocument 503 /deploy.html

  #... ssl config

  RequestHeader set X_FORWARDED_PROTO 'https'
  RequestHeader set X-Forwarded-Ssl on

  LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b" common_forwarded
  ErrorLog  /home/myuser/logs/gitlab_error.log
  CustomLog /home/myuser/logs/gitlab_forwarded.log common_forwarded
  CustomLog /home/myuser/logs/gitlab_access.log combined env=!dontlog
  CustomLog /home/myuser/logs/gitlab.log combined

</VirtualHost>

我唯一更改的配置是我的/etc/gitlab/gitlab.rb，我这样做是为了让代理工作。

external_url 'https://git.example.com'
nginx['enable'] = false
web_server['external_users'] = ['www-data']
gitlab_workhorse['listen_network'] = "tcp"
gitlab_workhorse['listen_addr'] = "127.0.0.1:8283"

我做错了什么，得到了502错误，而不是漂亮的“部署”页面，我用来之前得到这些变化？
如果您需要任何其他信息，请询问。
