OoD site shows 'Index of /' on root page

I moved the folders to a new server (symlinked to NFS).
sudo ln -s /shared/data/OoD/var/www/ood /var/www/
sudo ln -s /shared/data/OoD/etc/ood /etc/
sudo ln -s /shared/data/OoD/opt/ood /opt/

The original server is working with the same configuration.
I’m guessing it’s something with Apache I’m missing on the new server.

Thanks for any help.

Could you provide the intent of what you are doing and more information? I’m not sure what the issue is reading this or what you are doing.
