OpenSolr Turbo Indexer

Requirements

• Drupal 9, 10, or 11
• Search API module
• Search API Solr module
• PHP pcntl extension (for process forking)
• PHP posix extension
• CLI access (Drush)

Check PHP Extensions

Verify the required extensions are installed:

# Check for pcntl extension
php -m | grep pcntl

# Check for posix extension
php -m | grep posix

# Or check both at once
php -r "echo 'pcntl: ' . (extension_loaded('pcntl') ? 'OK' : 'MISSING') . PHP_EOL . 'posix: ' . (extension_loaded('posix') ? 'OK' : 'MISSING') . PHP_EOL;"

Installing Missing Extensions

Ubuntu/Debian

# Usually included, but if missing:
sudo apt-get install php-cli

# The pcntl and posix extensions are typically compiled into CLI PHP
# They may be disabled in php.ini for web (php-fpm) but should work in CLI

CentOS/RHEL

sudo yum install php-process

macOS (Homebrew)

# Usually included with PHP
brew install php

Drush Version

Any modern Drush version (10+) should work:

drush --version
