/home/git does not exists!

I have installed a new server with Ubunto 16.04 LTS

Nothing else!

After running the omnibus installation it worked. Now I tried to use an external Nginx server (on same physical server) but I keep getting the error:

connect() to unix:/home/git/gitlab/tmp/sockets/gitlab-workhorse.socket failed (2: No such file or directory)

Sure! The path /home/git/ does not exists!

What is wrong?
