Testing locally

This Vagrant configuration is meant for testing your setup locally first before provisioning the Packer image on someone else's server.

The way to use Vagrant is to provision an Ubuntu VM locally to test your configuration. This will allow you to make the necessary changes in the user-data.sh script before creating a deployable image. You can setup your store however you want and make all the necessary Wordpress (including MySQL) changes in the VM and build the image after that so you have less changes to make on the instance on GCP/AWS.

TODOs before running:

• Create a /extra with bitcoin/, lightning/, and charge/ directories. Copy data/ dir from the cloned repo into /extra. Vagrant will sync your local /extra to a directory in the VM. Make sure to check out the user-data.sh for details on how the directories are mounted and used in the containers. Also, it may not be a bad idea to sync your testnet/mainnet node before creating the store (i.e. rsync a tar with bitcoind's datadir); if not, that's fine as well
• There's some basic .conf files provided for bitcoind and c-lightning, so feel free to edit those as needed
• Edit the Wordpress and MySQL services to make sure they're using appropriate passwords, env vars, settings, etc.
• Edit the wp-setup.sh script to configure Wordpress appropriately (passwords, db info, etc.); you can also install additional WP plugins, or you can just install them in the UI, which is simpler to use than wp-cli

Note: Be aware that mounting /extra in the C-Lightning container may not work, so you'll have to switch to a Docker volume instead (-v lightning:/root/.lightning). The same change needs to be applied to Lightning Charge since it needs access to the lightning-rpc socket file. Also, if you get weird MySQL errors, the above should "fix" it - instead of using /extra/data/db, you'll need to update the mysql.service file to:

...
--user root \
-v db:/var/lib/mysql \
--entrypoint bash \
...
--name=wp-mysql \
-v db:/var/lib/mysql \
-p 3306:3306 \
...

You need to:

• stop the mysql.service
• update the mysql.service file
• systemctl daemon-reload
• systemctl restart mysql
• remove the volume directory's contents (docker volume inspect db to get the path) - rm -rf /var/lib/docker/volumes/db/_data/*
• copy data/db/ to the volume's directory - cp -R /extra/data/db/* /var/lib/docker/volumes/db/_data/
• and systemctl restart mysql again

Install Vagrant on Ubuntu:

wget https://releases.hashicorp.com/vagrant/2.2.4/vagrant_2.2.4_x86_64.deb
dpkg -i vagrant_2.2.4_x86_64.deb

Or other operating systems https://www.vagrantup.com/downloads.html.

Run Vagrant:

sudo vagrant up
sudo vagrant ssh

Inside Vagrant:

Start all services:

sudo systemctl start bitcoin lightning charge mysql
sudo systemctl start wp nginx

Verify everything's running:

You should be able to access your website locally (outside the Vagrant VM) on localhost/wp-admin (user: lightning, pw: some-secure-password!). If you're running Vagrant on a remote server that you have SSH'd into, just port-forward port 80 to your laptop (e.g. ssh -L 8080:localhost:80 server).

If you're having problems, check the troubleshooting section.
