Installation Guide for Strapi CMS on AlmaLinux 9, utilizing PostgreSQL, PM2, Nginx, and SSL

In this article, we'll walk you through the process of setting up Strapi CMS on AlmaLinux 9, a stable and long-lifecycle platform suitable for hardened, enterprise deployments. We'll use PostgreSQL for robust indexing and full-text search options, PM2 for process management, Nginx as a reverse proxy, and SSL for secure communication.

Step 1: Create and Connect to Your AlmaLinux 9 Server

First, set up an AlmaLinux 9 VPS and SSH into the server.

Step 2: Update System and Install Essentials

Run system updates and install base packages required for the installation.

Step 3: Install and Configure PostgreSQL 16

  • Install PostgreSQL 16 using .
  • Initialize and start the PostgreSQL service.
  • Create a database and user for Strapi.

Step 4: Install Node.js 20 and NPM

Use NodeSource to install Node.js 20:

Step 5: Create and Build the Strapi Project

  • Use or to create a new Strapi project configured to use PostgreSQL.
  • Build the project with .

Step 6: Install and Configure PM2

  • Install PM2 globally for process management:
  • Start Strapi with PM2 and configure PM2 to start on boot.

Step 7: Install and Configure Nginx as a Reverse Proxy

  • Install Nginx: .
  • Create a reverse proxy configuration file at with content like:

``` server { listen 80; server_name your_domain.com;

location / { proxy_pass http://127.0.0.1:1337; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_cache_bypass $http_upgrade; } } ```

  • Enable and restart Nginx:

Step 8: Secure with SSL Using Let’s Encrypt

  • Install Certbot and the Nginx plugin:
  • Obtain and install a free SSL certificate for your domain:

After these steps, your Strapi CMS will be accessible securely over HTTPS at your domain.

With this setup, Strapi CMS will provide strong concurrency and reliability under write/read load with PostgreSQL, and PM2 will manage the process, auto-restarting on crash or OOM, and rebooting with systemd.

Step 3: Install and Configure Technology for DatabaseIn this step, we'll install PostgreSQL 16, which is the technology we'll use for robust indexing and full-text search options for our Strapi CMS.

Step 8: Secure Communication with SSLFinally, to secure our communication, we'll set up SSL using Let’s Encrypt - another essential technology in today's highly connected world.
