bitte, wie man Github 6.0 mit Apache2 einstellt?

Gitlab wird gemäß der Originalanleitung installiert

Anpassung in Unicorn.rb

    ...
    #listen "/home/git/gitlab/tmp/sockets/gitlab.socket", :backlog => 64
    #listen "127.0.0.1:8080", :tcp_nopush => true
    listen "127.0.0.1:8080"
    ...

Mein Apache2 conf ist:

    <VirtualHost *:80>
        ServerName git.domain.com

        ErrorLog /var/log/apache2/gitlab_error.log
        CustomLog /var/log/apache2/gitlab_access.log combined

        ProxyRequests Off
        ProxyPreserveHost On
        ProxyPass / http://127.0.0.1:8080/
        <Location />
            ProxyPassReverse /
            Order deny,allow
            Allow from all
        </Location>
    </VirtualHost>

Bud ich bekomme:

    The proxy server received an invalid response from an upstream server.
    The proxy server could not handle the request GET /users/sign_in.

    Reason: Error reading from remote server

Vielen Dank
