Nginx Setup

For VPS, cloud servers, and dedicated servers with SSH and sudo access.

1. Set Variables

Replace these values:

export ACME_SERVER="your Server URL"
export EAB_KID="your EAB MAC ID"
export EAB_HMAC_KEY="your EAB MAC key"
export EMAIL="admin@example.com"
export DOMAIN="example.com"
export WEBROOT="/var/www/example.com/public"

2. Install acme.sh

curl https://get.acme.sh | sh -s email="$EMAIL"
source ~/.bashrc 2>/dev/null || source ~/.zshrc 2>/dev/null || true

3. Register the ACME Account

~/.acme.sh/acme.sh --register-account \
  --server "$ACME_SERVER" \
  --eab-kid "$EAB_KID" \
  --eab-hmac-key "$EAB_HMAC_KEY" \
  -m "$EMAIL"

4. Issue the Certificate

~/.acme.sh/acme.sh --issue \
  --server "$ACME_SERVER" \
  -d "$DOMAIN" \
  -w "$WEBROOT"

Include www:

~/.acme.sh/acme.sh --issue \
  --server "$ACME_SERVER" \
  -d "$DOMAIN" \
  -d "www.$DOMAIN" \
  -w "$WEBROOT"

5. Install the Certificate

sudo mkdir -p "/etc/ssl/12ssl/$DOMAIN"

sudo ~/.acme.sh/acme.sh --install-cert -d "$DOMAIN" \
  --key-file "/etc/ssl/12ssl/$DOMAIN/privkey.pem" \
  --fullchain-file "/etc/ssl/12ssl/$DOMAIN/fullchain.pem" \
  --reloadcmd "systemctl reload nginx"

6. Configure Nginx

sudo nano /etc/nginx/sites-available/example.com

Example:

server {
    listen 443 ssl http2;
    server_name example.com www.example.com;

    root /var/www/example.com/public;
    index index.html index.php;

    ssl_certificate /etc/ssl/12ssl/example.com/fullchain.pem;
    ssl_certificate_key /etc/ssl/12ssl/example.com/privkey.pem;

    location / {
        try_files $uri $uri/ =404;
    }
}

server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$host$request_uri;
}

Check and reload:

sudo nginx -t
sudo systemctl reload nginx

7. Check

curl -I "https://$DOMAIN"

Open:

https://example.com
