Запускаем Redmine и Gitlab на уникальном сервере apache

Я работаю над проектом, где я должен работать одновременно GitLab и Redmine на том же виртуальная машина используя apache2. Я начал устанавливать омнибус-GitLab (описано здесь https://about.gitlab.com/installation/#ubuntu) и отредактировал gitlab.rb, чтобы его можно было использовать с apache2 (задокументировано здесь https://docs.gitlab.com/omnibus/settings/nginx.html#using-a-non-bundled-web-server). Gitlab работал (url = my_ip / gitlab) до установки Redmine, но после этой установки (задокументировано здесь: http://www.redmine.org/projects/redmine/wiki/howto_install_redmine_on_ubuntu_step_by_step) GitLab возвращает 404 (redmine хорошо работает с url my_ip / redmine). Единственное, что я мог понять, это то, что GitLab снова работает, когда я отключу виртуальный хост Redmine. Вот мой vhost:

GitLab vhost (находится здесь https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache):

# This configuration has been tested on GitLab 8.2
# Note this config assumes unicorn is listening on default port 8080 and
# gitlab-workhorse is listening on port 8181. To allow gitlab-workhorse to
# listen on port 8181, edit /etc/gitlab/gitlab.rb and change the following:
#
# gitlab_workhorse['listen_network'] = "tcp"
# gitlab_workhorse['listen_addr'] = "127.0.0.1:8181"

</VirtualHost>

Redmine vhost (здесь: http://www.redmine.org/projects/redmine/wiki/howto_install_redmine_on_ubuntu_step_by_step)

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
        <Directory /var/www/html/redmine>
                RailsBaseURI /redmine
                PassengerResolveSymlinksInDocumentRoot on
        </Directory>
</VirtualHost>

Решение, на котором я пытаюсь сосредоточиться, - это один-единственный файл conf, включающий оба vhosts
