Setting up Coauthor on a new Lighsail instance

Setup: Ubuntu 14.04 Lightsail instance with static IP address, DNS type A record linking the static IP to domain name (ravivakil.org)

1. SSH into the server by running $ ssh -i /path/to/private/key ubuntu@ravivakil.org
2. Securely move the private key onto the server (is this safe?) $ scp -i /path/to/private/key /path/to/private/key ubuntu@ravivakil.org:home/ubuntu/
3. Install node.js, version 12.x.x (see https://github.com/nodesource/distributions/blob/master/README.md) by running $ curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - followed by $ sudo apt-get install -y nodejs
4. Download meteor by running $ curl https://install.meteor.com/ | sh
5. Download Coauthor via git by running $ cd ~ && git clone https://github.com/edemaine/coauthor.git. Also create a build directory for later: $ cd ~ && mkdir coauthor-build
6. Setup SSL certificates by following the instructions here: https://certbot.eff.org/lets-encrypt/ubuntuxenial-other

1. Clone the git repo into ~/opencv
2. Clone the opencv_contrib repo into ~/opencv_contrib
3. In both dirs, run git checkout 3.1.0
4. In ~/opencv, mkdir build; cd build; and run the cmake command below:

cmake -D WITH_CUDA=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \

Doubtful it stood;
As two spent swimmers, that do cling together
And choke their art. The merciless Macdonwald--
Worthy to be a rebel, for to that
The multiplying villanies of nature
Do swarm upon him--from the western isles
Of kerns and gallowglasses is supplied;
And fortune, on his damned quarrel smiling,
Show'd like a rebel's whore: but all's too weak:
For brave Macbeth--well he deserves that name--
