Hi. Anyone have tips to share on Ubuntu Server 16.04?

I told Ubuntu to install LAMP and PostgreSQL. I hand-installed NPM using these instructions: https://www.godaddy.com/help/set-up-nodejs-application-for-production-ubuntu-17352

sudo apt-get install php7.0-pgsql php7.0-curl php7.0-mbstring php7.0-gd php7.0-xml php7.0-apcu php-apcu

Gets me past most of the missing components.

Problems

The install docs seem to be leaving out how to configure the PostgreSQL account, it seems to be looking for 'host' and 'user'? Should I be editing a config to set these, and is there a shell way to add this user to the database?

I'm also running into issues with locale.js errors in moment, like this: https://github.com/moment/moment/issues/2979

Thank you.
