Phasefield.net

Setup

Assuming the webserver runs as user www-data and the site is installed at /var/www/phasefield_site

`sudo` setup

Add

www-data ALL = (root) NOPASSWD: /var/www/phasefield_site/scripts/run_moose.sh

To the bottom of /etc/sudoers. Make sure the run_moose.sh is not writable by any unprivileged account!

Prerequisites

sudo apt install nodejs npm makejail

MOOSE compile

Install the redistributable package and build MOOSE in any user home directory as an unprivileged user. In the root of the moose repository run

./scripts/update_and_rebuild_libmesh.sh
cd modules/combined
make -j 4

Now in the combined directory run the install script

sudo /var/www/phasefield_site/scripts/install.sh

Launching the server

The node based server is started with

cd /var/www/phasefield_site
sudo ./bin/www

If the server is started with super user privileges it drops these privileges by switching to the user and group specified in the WWW_USER and WWW_GROUP environment variables (defaulting to www-data).

The server binds to the port specified in the PORT environment variable (defaults to 80). If the server should run on a privileged port it needs to be launched either with super user priviliges (which are dropped as soon as the port is bound) or using authbind.
