Gitlab integration on rhel 6.7

Hi to all,
we installed the following rpm gitlab-ce-8.5.10-ce.0.el6.x86_64.rpm on our Red Hat Enterprise Linux Server release 6.6 but we weren’t able to use the init script provided.
The upstart script under /etc/init it’s ablle only to start the gitalb infrastructure but when we need to stop the services the only process terminated is runsvdir -P /opt/gitlab/service.

We can’t use the init.d script provided by rpm because we weren’t able to find the rigth $app_root path.
Can someone provide some help abou this problem ?
Many thanks
