Server Setup

Create a new user

Open up your terminal and login to your new server as the root user:

# Login via SSH
ssh [email protected]<your_server_ip>

# Create a new user and follow prompts
adduser <user>

# Add user to superuser group to unlock admin privileges
usermod -aG sudo <user>

# Then log in as the new user
su - <user>

Update packages

Ensure package lists and installed packages are up to date.

# Update package lists
sudo apt-get update

# Update installed packages
sudo apt-get upgrade

Follow any prompts to enter the password you just created in the previous step.

Install NGINX

LogChimp uses an NGINX server and the SSL configuration.

# Install NGINX
sudo apt-get install nginx

Allow firewall connection at HTTP, HTTPS and OpenSSH.

sudo ufw allow 'Nginx HTTP'
sudo ufw allow 'Nginx HTTPS'
sudo ufw allow 'OpenSSH'

Install PostgreSQL

Next, you’ll need to install PostgreSQL to be used as the production database.

# Install PostgreSQL
sudo apt-get install postgresql-12 postgresql-contrib

Create <user> (a.k.a role) for database using psql prompt.

# Open postgresql prompt
sudo -u postgres psql

# Create new user with SUPERUSER
CREATE ROLE <user> PASSWORD '<password>' SUPERUSER;

# Create database
CREATE DATABASE <database name>;

# Then exit postgresql prompt
quit

Install Node.js

You will need to have a supported version of Node installed system-wide in the manner described below. If you have a different setup, you may encounter problems.

# Add the NodeSource APT repository for Node 12
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash

# Install Node.js
sudo apt-get install -y nodejs

# Install yarn
sudo npm install [email protected] -g

Install LogChimp

Install LogChimp server

# Create 'server' directory
sudo mkdir server && cd server

# Get the latest release tag name
LATEST_RELEASE_TAG=$(curl --silent "https://api.github.com/repos/logchimp/logchimp/releases/latest" | grep '"tag_name":' | sed -E 's/.*"([^"]+)".*/\1/')

# Downloading logchimp server to current directory
sudo curl -L -o logchimp-server.tar.gz "https://api.github.com/repos/logchimp/logchimp/tarball/$LATEST_RELEASE_TAG"

After extracting the files to current directory.

# Delete the zip file (optional)
sudo rm logchimp-server.tar.gz

# Install packages using yarn
yarn

Configuration

Create logchimp.config.json configuation file in current directory using LogChimp CLI.

Setup Nginx

cd /etc/nginx/sites-available/

# Create nginx configuration for your domain
sudo nano <your_domain>

Now paste this configuration and save the changes

server {
  listen 80;
  listen [::]:80;

  server_name <your_domain> www.<your_domain>;

  root  /home/logchimp/theme/dist;

  location / {
    index  index.html;
    try_files $uri $uri/ /index.html;
  }

  location /api {
    proxy_pass http://127.0.0.1:3000;
  }

  error_page   500 502 503 504  /50x.html;
  location = /50x.html {
    root   /usr/share/nginx/html;
  }
}

sudo ln -s /etc/nginx/sites-available/<your_domain> /etc/nginx/sites-enabled/

Add SSL certificate to your domain

You're either add your own SSL certificate or create one for free by following the steps:

# Install certbot
sudo apt-get install certbot python3-certbot-nginx -y

Obtaining an SSL certificate

sudo certbot --nginx -d <your_domain>

Lastly, certbot will ask how you’d like to configure your HTTPS settings. Select 2 and hit Enter. The configuration will be updated, and Nginx will reload to pick up the new settings.

🎉 Congrats! You've successfully setup your own LogChimp site.
