Server Services & PHP Configuration

⚙️ Services Tab

Control server services and PHP configuration.

PHP Configuration

Adjust PHP settings for your websites:

• Memory Limit - How much RAM PHP can use (e.g., 256M, 512M)
• Upload Max Size - Maximum file upload size
• Post Max Size - Maximum POST request size
• Max Execution Time - Script timeout in seconds
• Max Input Vars - Maximum form fields

PHP Presets

Quick configuration with optimized settings:

• Production - Secure settings, opcache enabled, errors hidden
• Development - Verbose errors, no caching, detailed logging

Service Control

• Restart Apache - Reload web server configuration
• Restart PHP-FPM - Reload PHP processor
• Restart MySQL - Restart database server
• Caching services - Memcached, Redis and Varnish (when installed) can be started, stopped, restarted or reloaded from their own cards

Cache Stats (Varnish & Memcached)

Running Varnish and Memcached services show a Stats button on their card. One click opens a live snapshot of how your cache is performing:

• Cache hit rate - The headline number: how many requests were answered straight from cache
• Requests - Client requests, cache hits and misses, backend fetches (Varnish) or get/set commands (Memcached)
• Grace hits - Varnish only: slightly stale pages served instantly while a fresh copy was fetched in the background
• Objects & memory - How many objects are cached and how much of the cache memory is in use
• Evictions - Objects thrown out early to make room; consistently above zero means the cache is too small

Every metric has an info icon - hover it for a plain-English explanation. Counters are cumulative since the service last started, and the dialog shows exactly how long that was.

PHP-FPM Status

Monitor PHP-FPM pool status:

• Active processes
• Idle processes
• Total requests served
• Memory usage per process
