Deploying Node

This list of commands is based on my talk in Node.js Global Summit tested on Digital Ocean, CentOS 8.

dnf -y install vim

# installing node
curl -sL https://rpm.nodesource.com/setup_14.x | bash -
dnf -y install nodejs

# create non-root user, always good idea
adduser juriy

# become that user
sudo su - juriy


# allow logging in with the same key as root uses (your key if it was Digital Ocean) 
mkdir .ssh
chmod 700 .ssh
touch .ssh/authorized_keys
chmod 600 .ssh/authorized_keys

# become root again
logout
cat ~/.ssh/authorized_keys >> /home/nanogram/.ssh/authorized_keys


# on your LOCAL environment, grab the code you want to run 
# (choose your files and folders)
tar czf app.tar.gz client server
scp app.tar.gz [email protected]:

# going back to the server, as non-root user 
# (assuming we are in home folder)
mkdir app
tar xf app.tar.gz -C app
cd app
npm i

# just check that app works, but don't leave it this way, 
# the process will halt once you log out!!!
npm start

# run following as root user
npm i -g pm2

# go back to your app as non-root user
pm2 start main.js

# save config, when server is restarted it will run your app automatically
pm2 save

# run below as root again
# this command will make sure that PM2 itself starts when the server is rebooted
pm2 startup -u juriy --hp /home/juriy

# install nginx
dnf install nginx

# start editing config, change for your domain
vim /etc/nginx/conf.d/beta.juriy.com.conf


Basic config looks like that:

server {
  listen       80;
  listen       [::]:80;
  server_name  beta.juriy.com;

  location / {
    proxy_pass "http://localhost:8080/";
  }
}

# important! NGINX will not be allowed to connect to NODE
# without this permission
setsebool -P httpd_can_network_connect on

# enable couple of repos required for the next tools to be installed
dnf install -y epel-release
dnf config-manager --set-enabled PowerTools

# get certbot
dnf install certbot python3-certbot-nginx

# let certbot do all the job of getting the certificate
certbot --nginx
