https://jasonwatmore.com/post/2019/11/18/react-nodejs-on-aws-how-to-deploy-a-mern-stack-app-to-amazon-ec2

Start up EC2 ^^
Log in
Install Node
- Download and install nvm: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
  - https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-up-node-on-ec2-instance.html
- log out of the instance
- log back in
- Install Node:
```
# install node
nvm install node
# initiate nvm with new node version
. ~/.nvm/nvm.sh
# ensure desired version of node is running
node -e "console.log('Running Node.js ' + process.version)"
```
Install Mongo
- Import the public key used by the package management system: wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -
- Create a list file for MongoDB: echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list
- Reload local package database: sudo apt-get update
- Install MongoDB packages: sudo apt-get install -y mongodb-org
Start up Mongo
- sudo systemctl start mongod
- Verify it is running: sudo systemctl status mongod
- Stop/restart: sudo systemctl stop mongod / sudo systemctl restart mongod
- Use the shell: mongosh
Copy db data to instance
- you can use scp, or something like filezilla
  - filezilla: https://ganevniko.github.io/using_filezilla_to_upload_files_into_an_aws_ec2_instance
  - scp: https://dearsikandarkhan.medium.com/files-copying-between-aws-ec2-and-local-d07ed205eefa
```
$ scp -i /directory/to/abc.pem user@ec2-xx-xx-xxx-xxx.compute-1.amazonaws.com:path/to/file /your/local/directory/files/to/download
```

SERVER

start an ec2 instance
- Amazon Linux
- t2 micro
- security, enable http on 80 and ssh on 22
- use same pem as above
install repo
- ssh in ssh -i pemfile ec2-user@blahblah
- sudo yum install git
- clone repo in git clone https://github.com/...
install node
- curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
- restart instance
- nvm install node
- . ~/.nvm/nvm.sh
- node -e "console.log('Running Node.js ' + process.version)"
- npm install -g npx
install nginx
- sudo amazon-linux-extras install nginx1
- sudo service nginx start
- set up nginx config
  - sudo vim /etc/nginx/nginx.conf
  - Before the other location blocks within server {, insert:
```
location / {
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header Host      $http_host;
  proxy_pass       http://127.0.0.1:3000; 
}
```
  - Also ensure that the port your server is listening for has been set within the server block
- restart nginx
make nginx persistent
- sudo systemctl start nginx
- sudo systemctl enable nginx
npm install everything in your repo
Initiate your server

install redis

https://medium.com/@andrewcbass/install-redis-v3-2-on-aws-ec2-instance-93259d40a3ce

sudo yum -y install gcc make # install GCC compiler
cd /usr/local/src
sudo wget http://download.redis.io/redis-stable.tar.gz
sudo tar xvzf redis-stable.tar.gz
sudo rm -f redis-stable.tar.gz
cd redis-stable
sudo yum groupinstall "Development Tools"
sudo make distclean
sudo make
sudo yum install -y tcl
sudo make test
sudo cp src/redis-server /usr/local/bin/
sudo cp src/redis-cli /usr/local/bin/

test by running redis-server & and check ports with sudo lsof -i -P -n | grep LISTEN. Should see port open with redis-server. Kill by running kill {PID}, pid being the number in lsof.

If you want your server to persist, use pm2
- npm i -g pm2
- run this pm2 startup and copy its output
- run that output? I think
- pm2 save
- pm2 start nodemon path/to/server.js
- This will allow the server to persist on logout and on server restart

Run It All

Mongo

sudo systemctl start mongod

Server

sudo service nginx start
redis-server & npm start
on close: sudo lsof -i -P -n | grep LISTEN and kill {PID} for redis

Other AWS stuff

Each Linux instance launches with a default Linux system user account. The default user name is determined by the AMI that was specified when you launched the instance.

For Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user.
For a CentOS AMI, the user name is centos.
For a Debian AMI, the user name is admin.
For a Fedora AMI, the user name is ec2-user or fedora.
For a RHEL AMI, the user name is ec2-user or root.
For a SUSE AMI, the user name is ec2-user or root.
For an Ubuntu AMI, the user name is ubuntu.
Otherwise, if ec2-user and root don't work, check with the AMI provider.
