Prerequisites & System Requirements

An Ubuntu 24.04 VPS with LEMP stack installed. Recommended: IndSoft Managed WordPress Hosting.

1

Create Dedicated WordPress Database and User

Create an isolated database and grant permissions for your WordPress instance.

bash · step-1-command.sh
sudo mysql -u root -p CREATE DATABASE wp_production DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_520_ci; CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'SECURE_PASSWORD'; GRANT ALL ON wp_production.* TO 'wp_user'@'localhost'; FLUSH PRIVILEGES; EXIT;
Expected System Output:
Query OK, 0 rows affected
2

Download and Extract Latest WordPress Core

Download the latest verified WordPress archive directly from wordpress.org.

bash · step-2-command.sh
cd /var/www sudo curl -O https://wordpress.org/latest.tar.gz sudo tar -xzvf latest.tar.gz sudo mv wordpress example.com sudo chown -R www-data:www-data /var/www/example.com sudo find /var/www/example.com/ -type d -exec chmod 755 {} \; sudo find /var/www/example.com/ -type f -exec chmod 644 {} \;
Expected System Output:
WordPress core files deployed with www-data ownership.

Configure Nginx FastCGI Microcache

Add fastcgi_cache_path to /etc/nginx/nginx.conf and configure caching rules in your server block.

bash · step-3-command.sh
sudo nano /etc/nginx/conf.d/fastcgi-cache.conf # fastcgi_cache_path /var/run/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m; sudo systemctl reload nginx
Expected System Output:
Cache zone initialized.

Troubleshooting Common Errors

Quick resolutions for frequent setup pitfalls and configuration issues.

Diagnostic Tips
WordPress prompts for FTP credentials when uploading media
Fix directory ownership so the PHP-FPM process can write to wp-content: sudo chown -R www-data:www-data /var/www/example.com/wp-content.
404 errors on pretty permalinks
Ensure your Nginx location block includes: try_files $uri $uri/ /index.php?$args;.
FastCGI Cache status shows 'BYPASS' or 'MISS'
Check if cookies (e.g. comment_author or woocommerce_items_in_cart) are triggering cache skip rules in your Nginx config.
