Varnish is a powerful HTTP accelerator designed for content-heavy dynamic websites. When used with Nginx, it can help offload the SSL termination process. In this guide, we will walk through the steps to set up Varnish for SSL termination with an Nginx web server on Rocky Linux 8.
Step 1: Update Your System
Start by ensuring your system is up to date:
sudo dnf update -yStep 2: Install Varnish and Nginx
Install Varnish and Nginx by running the following command:
sudo dnf install -y varnish nginxStep 3: Configure Nginx
Edit the Nginx configuration file to set it up for Varnish. Open the default configuration file:
sudo nano /etc/nginx/nginx.confAdd the following server block to configure Nginx to listen on port 8080:
server {
listen 8080;
server_name your_domain.com; # Replace with your domain
location / {
proxy_pass http://127.0.0.1:8081; # Varnish will listen on this port
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}Step 4: Configure Varnish
Edit the Varnish default configuration file:
sudo nano /etc/varnish/default.vclSet the backend to Nginx:
backend default {
.host = "127.0.0.1";
.port = "8081";
}Make sure Varnish listens on port 8080 for incoming SSL traffic:
sub vcl_recv {
if (req.http.X-Forwarded-Proto) {
set req.http.X-Forwarded-Proto = "https";
}
}Step 5: Set Up SSL Certificates
Obtain SSL certificates using Certbot:
sudo dnf install certbot python3-certbot-nginx -y
sudo certbot --nginx -d your_domain.comFollow the prompts to configure your SSL certificate. Certbot will automatically configure Nginx for SSL.
Step 6: Start and Enable Varnish and Nginx
Start Varnish and enable it to run at startup:
sudo systemctl start varnish
sudo systemctl enable varnishStart Nginx and enable it to run at startup:
sudo systemctl start nginx
sudo systemctl enable nginxStep 7: Access Your Website
Now, you can access your website securely at:
https://your_domain.comConclusion
