curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
sudo yum install -y nodejs

Check the versions.

node -v && npm -v
# v8.11.4
# 5.6.0

Install MariaDB

sudo yum install -y mariadb-server

Check the version.

mysql --version

Start and enable MariaDB.

sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Run the mysql_secure installation script to improve security.

sudo mysql_secure_installation

Connect to the MariaDB shell as the root user.

mysql -u root -p

Create an empty database and user, and remember the credentials.

CREATE DATABASE dbname;
GRANT ALL ON dbname.* TO 'username' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit

Install Nginx

sudo yum install -y nginx

Check the version.

nginx -v

Start and enable Nginx.

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Configure Nginx as an HTTP or HTTPS (if you use SSL) reverse proxy for Mailtrain. Run sudo vi /etc/nginx/conf.d/mailtrain.conf and add the following configuration.

server {

  listen [::]:80;
  listen 80;

  server_name example.com;

  charset utf-8;
  client_max_body_size 50M;


  location / {
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_pass http://127.0.0.1:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_next_upstream error timeout http_502 http_503 http_504;
  }

}

Test the configuration.

sudo nginx -t

Reload Nginx.

sudo systemctl reload nginx.service

Install Mailtrain

sudo mkdir -p /var/www/mailtrain

Navigate to the document root folder.

cd /var/www/mailtrain

Change ownership of the /var/www/mailtrain folder to user johndoe.

unzip master.zip
rm master.zip
mv mailtrain-master/* . && mv mailtrain-master/.* .

vi config/production.toml

Run the server.

NODE_ENV=production npm start
