Installing and Configuring WordPress on a Server
WordPress often slows down on shared hosting with just 500 visitors — this results from suboptimal server configuration. A real case: an online store with 3,000 visitors per day took 10 seconds to load, causing a 40% drop in conversion. We migrated it to a VPS with Nginx and PHP 8.3, set up caching and CDN — load time dropped to 1.5 seconds, conversion rose by 30%. Savings on hosting with the right VPS choice can reach 40% compared to suboptimal plans. The setup cost pays off through increased conversion — in the case above, conversion grew by 30%. We configure WordPress turnkey: from hosting selection to a production-ready configuration.
Why Is Correct Server Configuration Important?
On shared hosting, you share resources with neighbors — CPU, RAM, and even MySQL. Under peak load, your site may go down. A VPS (Virtual Private Server) provides an isolated environment but requires manual LEMP (Linux, Nginx, MySQL, PHP) or LAMP setup. The performance difference is enormous: a properly configured Nginx handles static files 10x faster than Apache. Let's compare options:
| Feature | Shared Hosting | VPS |
|---|---|---|
| Setup | 5–10 min, auto | 3–4 hours manual |
| Performance | Medium, neighbor-dependent | High, resources are yours |
| Flexibility | Limited | Full server access |
| Security | Basic | Configurable per project |
| Cost-effectiveness | Affordable | Moderate investment |
Conclusion: For a blog or small business, shared hosting suffices; for an online store or site with 10,000+ visitors, you need a VPS.
How to Manually Configure WordPress on a VPS?
Installation on Ubuntu LTS with Nginx and PHP 8.3 involves several steps. First, install the packages:
apt install nginx php8.3-fpm php8.3-mysql php8.3-curl php8.3-gd \ php8.3-mbstring php8.3-xml php8.3-zip php8.3-intl mysql-server Create a database and user:
mysql -u root -e " CREATE DATABASE wordpress CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'strong-password-here'; GRANT ALL PRIVILEGES ON wordpress.* TO 'wp_user'@'localhost'; FLUSH PRIVILEGES;" Download WordPress and set permissions:
cd /var/www wget https://wordpress.org/latest.tar.gz tar xzf latest.tar.gz mv wordpress yourdomain.com chown -R www-data:www-data yourdomain.com wp-config.php Configuration
define('DB_NAME', 'wordpress'); define('DB_USER', 'wp_user'); define('DB_PASSWORD', 'strong-password-here'); define('DB_HOST', 'localhost'); define('DB_CHARSET', 'utf8mb4'); // Unique keys from https://api.wordpress.org/secret-key/1.1/salt/ define('AUTH_KEY', '...'); // ... // Force HTTPS define('FORCE_SSL_ADMIN', true); // Disable file editing from admin define('DISALLOW_FILE_EDIT', true); // Revision limit define('WP_POST_REVISIONS', 5); // Autosave interval define('AUTOSAVE_INTERVAL', 120); Nginx Configuration
server { listen 443 ssl http2; server_name yourdomain.com www.yourdomain.com; root /var/www/yourdomain.com; index index.php; ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem; client_max_body_size 64M; location / { try_files $uri $uri/ /index.php?$args; } location ~ \.php$ { fastcgi_pass unix:/var/run/php/php8.3-fpm.sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2)$ { expires 1y; add_header Cache-Control "public, immutable"; } # Deny access to wp-config and .htaccess location ~ /\.(htaccess|git) { deny all; } location = /wp-config.php { deny all; } } How to Protect WordPress from Hacking?
Right after installation, configure a firewall. Wordfence is one of the best free plugins: it blocks brute-force attacks and scans files for malicious code. Also install UpdraftPlus for automatic cloud backups (Google Drive, Dropbox). For caching, use WP Rocket or LiteSpeed Cache. Let's compare caching plugins:
| Plugin | Speed | Price | Features |
|---|---|---|---|
| WP Rocket | High | Paid | Easy setup, CDN support |
| LiteSpeed Cache | Very high | Free | Requires LiteSpeed server |
| W3 Total Cache | Medium | Free | Complex configuration, many options |
Do not install plugins "just in case" — each plugin increases the attack surface and slows down the site.
Optimization After Installation
After the basic setup, perform optimization:
- Enable caching via a plugin — this reduces page load time by 60–80%.
- Set up CDN (Cloudflare) for static assets.
- Install an image compression plugin (EWWW Image Optimizer).
- Limit revisions in wp-config.php (see above).
- Enable Gzip compression at the Nginx level.
- Connect monitoring (New Relic or similar) to track bottlenecks.
Initial Settings
After installation, perform basic settings: choose permalinks in /%postname%/ format, set the time zone, disable comments if not needed, update all components, remove default themes and unnecessary plugins.
