How to install the java and nodejs dependencies for AWS Greengrass

Greengrass v1.7 specifically supports Java 8 and NodeJS 6.10, and it requires the binaries be in the PATH and a specific file name.

On an Amazon Linux 2 AMI EC2 Instance

# install java
sudo yum install -y java-1.8.0-openjdk
sudo mv /usr/bin/java /usr/bin/java8
    
# install nodejs
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
nvm install 6.10
sudo cp ~/.nvm/versions/node/v6.10.3/bin/node /usr/bin/nodejs6.10

On Ubuntu 16.04

# install java
sudo apt-get install default-jre
sudo mv /usr/bin/java /usr/bin/java8

# install nodejs
curl -o- -L -k https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
nvm install 6.10
sudo cp ~/.nvm/versions/node/v6.10.3/bin/node /usr/bin/nodejs6.10
