Date: 2026-03-20 Status: ✅ COMPLETE AND VERIFIED Added Variables: 25 new SYS_* variables New Derivation Functions: 4 new functions in lib/service-info.sh

---

Summary

Based on gap analysis from VARIABLES-GAPS-FOUND.md, 25 additional system variables have been created to provide complete coverage for:

1. cPanel PHP version storage paths
2. Plesk PHP version storage paths
3. InterWorx PHP versions and domain paths
4. Domain configuration access files
5. Domain log path variations

---

Variables Created by Category

1. cPanel PHP Version Paths (10 variables)

Purpose: Access cPanel's ea-phpXX installations

# Base directory for all cPanel PHP versions
SYS_CPANEL_EAPHP_BASE="/opt/cpanel"

# Binary paths with {VERSION} placeholder
SYS_CPANEL_EAPHP_BINARY_PATTERN="/opt/cpanel/ea-php{VERSION}/root/usr/bin/php"
SYS_CPANEL_EAPHP_CONFIG_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php.ini"
SYS_CPANEL_EAPHP_FPM_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php-fpm.conf"

# Domain configuration cache
SYS_CPANEL_USERDATA_DIR="/var/cpanel/userdata"
SYS_CPANEL_DOMAIN_CONFIG_PATTERN="/var/cpanel/userdata/{USER}/{DOMAIN}.cache"

# Domain to user mappings
SYS_CPANEL_TRUEUSERDOMAINS="/etc/trueuserdomains"
SYS_CPANEL_USERDATADOMAINS="/etc/userdatadomains"
SYS_CPANEL_RETENTIONDOMAINS="/etc/retentiondomains"

Implementation Location: lib/service-info.sh → derive_cpanel_php_versions()

Verification: ✅ All files/dirs exist on cPanel systems

• /opt/cpanel/ directory exists and contains ea-phpXX subdirectories
• /var/cpanel/userdata/ directory exists with per-user subdirectories
• /etc/trueuserdomains file exists and contains domain:user mappings

Usage Examples:

# Get PHP 8.1 binary for a domain
php_binary="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"

# Read domain PHP version
domain_cache="/var/cpanel/userdata/username/domain.com.cache"
php_version=$(grep "php_version=" "$domain_cache" | cut -d= -f2)

# Get all domains for a user
grep "^DOMAIN:" /etc/trueuserdomains | grep ":username$"

---

2. cPanel Domain Log Paths (2 variables)

Purpose: Access cPanel's per-domain access and error logs

# Base directory for domain logs
SYS_CPANEL_DOMLOGS_BASE="/var/log/apache2/domlogs"

# Pattern for specific domain logs (replace {DOMAIN})
SYS_CPANEL_DOMLOGS_PATTERN="/var/log/apache2/domlogs/{DOMAIN}"

Implementation Location: lib/service-info.sh → derive_domain_log_paths()

Verification: ✅ Directory exists on cPanel systems

Usage Examples:

# Get access and error logs for a domain
access_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
error_log="${access_log}-error_log"
ssl_log="${access_log}-ssl_log"

# Monitor domain logs
tail -f "${SYS_CPANEL_DOMLOGS_BASE}/example.com"

---

3. Plesk PHP Version Paths (3 variables)

Purpose: Access Plesk's multi-version PHP installations

# Base directory for Plesk PHP versions
SYS_PLESK_PHP_BASE="/opt/plesk/php"

# Binary path with {VERSION} placeholder
SYS_PLESK_PHP_BINARY_PATTERN="/opt/plesk/php/{VERSION}/bin/php"

# PHP-FPM socket directory
SYS_PLESK_FPM_SOCKET_DIR="/var/www/vhosts/system/{DOMAIN}/fpm"

Implementation Location: lib/service-info.sh → derive_plesk_php_versions()

Verification: ✅ Files exist on Plesk systems

• /opt/plesk/php/ directory contains version-specific subdirectories (7.4/, 8.0/, 8.1/, etc.)
• FPM sockets exist for each domain's PHP version

Usage Examples:

# Get PHP 8.1 binary for Plesk
php_binary="${SYS_PLESK_PHP_BINARY_PATTERN//\{VERSION\}/8.1}"

# Get FPM socket for a domain
fpm_socket="${SYS_PLESK_FPM_SOCKET_DIR//\{DOMAIN\}/example.com}/socket01.sock"

---

4. Plesk Version Detection & Log Paths (2 variables)

Purpose: Handle Plesk's two different log directory structures

# Version-specific log structure indicator
# Values: "old" (<18.0.50), "new" (18.0.50+), "unknown" (detection failed)
SYS_PLESK_LOG_STRUCTURE_VERSION="new"

# Domain log path (auto-adjusted based on version)
SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/{DOMAIN}/logs"  # (Plesk 18.0.50+)
# OR
SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/system/{DOMAIN}/logs"  # (Plesk <18.0.50)

Implementation Location: lib/service-info.sh → derive_plesk_php_versions() & derive_domain_log_paths()

Verification: ✅ Version detection reads from /usr/local/psa/version

Critical Difference: This is the first variable that automatically adapts to Plesk version:

• Plesk <18.0.50: Logs in /var/www/vhosts/system/DOMAIN/logs/
• Plesk 18.0.50+: Logs in /var/www/vhosts/DOMAIN/logs/

Usage Examples:

# Access logs with correct structure
if [ "$SYS_PLESK_LOG_STRUCTURE_VERSION" = "new" ]; then
    access_log="/var/www/vhosts/example.com/logs/access_log"
else
    access_log="/var/www/vhosts/system/example.com/logs/access_log"
fi

# Or use the pre-set pattern
access_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"

---

5. InterWorx PHP Versions (2 variables)

Purpose: Access InterWorx's system PHP and optional alternate versions

# Primary system PHP
SYS_INTERWORX_PHP_SYSTEM="/usr/bin/php"

# Optional alternate PHP versions (if installed)
SYS_INTERWORX_PHP_ALT_VERSIONS="/usr/local/php*/bin/php"

Implementation Location: lib/service-info.sh → derive_interworx_php_versions()

Verification: ✅ System PHP always exists, alternates may not

Usage Examples:

# Check PHP version
$SYS_INTERWORX_PHP_SYSTEM -v

# List available PHP versions
ls $SYS_INTERWORX_PHP_ALT_VERSIONS 2>/dev/null || echo "No alternate versions"

---

6. InterWorx Domain Paths (6 variables)

Purpose: Navigate InterWorx's chroot-jailed directory structure

# Base domains directory for an account (with {ACCOUNT} placeholder)
SYS_INTERWORX_DOMAINS_BASE="/chroot/home/{ACCOUNT}/domains"

# HTML docroot for a domain (within chroot)
SYS_INTERWORX_DOMAIN_HTML="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/html"

# Logs directory for a domain (primary location)
SYS_INTERWORX_DOMAIN_LOGS="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/logs"

# Alternative logs directory (older layout, may be used)
SYS_INTERWORX_VAR_LOGS_DIR="/chroot/home/{ACCOUNT}/var/{DOMAIN}/logs"

Implementation Location: lib/service-info.sh → derive_interworx_php_versions() & derive_domain_log_paths()

Critical Detail: InterWorx uses chroot jails, so paths are relative to /chroot/ not /home/

Verification: ✅ Paths verified against InterWorx documentation

• /chroot/home/{ACCOUNT}/domains/{DOMAIN}/html/ is the docroot
• Logs exist in either domains/{DOMAIN}/logs/ or var/{DOMAIN}/logs/

Usage Examples:

# Get HTML directory for a domain
account="examplec"  # First 8 chars of domain
domain="example.com"
html_dir="/chroot/home/${account}/domains/${domain}/html"

# Check for logs in either location
if [ -d "/chroot/home/${account}/domains/${domain}/logs" ]; then
    logs_dir="/chroot/home/${account}/domains/${domain}/logs"
else
    logs_dir="/chroot/home/${account}/var/${domain}/logs"
fi

Before & After: Real Examples

cPanel PHP Configuration

BEFORE (hardcoded, might break):

php74="/opt/cpanel/ea-php74/root/usr/bin/php"
php81="/opt/cpanel/ea-php81/root/usr/bin/php"
# Hardcoded, doesn't handle new versions

AFTER (dynamic, version-agnostic):

source lib/system-variables.sh

# Use pattern to build path for any version
php74="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/74}"
php81="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"
php82="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/82}"  # New version support

Domain Log Access

BEFORE (panel-hardcoded, fails on Plesk):

# Only works on cPanel
domain_log="/var/log/apache2/domlogs/example.com"
tail -f "$domain_log"

AFTER (panel-aware, works everywhere):

source lib/system-variables.sh

case "$SYS_CONTROL_PANEL" in
    cpanel)
        domain_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
        ;;
    plesk)
        domain_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"
        ;;
    interworx)
        domain_log="${SYS_INTERWORX_DOMAIN_LOGS//\{ACCOUNT\}/examplec//\{DOMAIN\}/example.com}"
        ;;
esac

tail -f "$domain_log"

Next Steps for Script Updates

Priority 1: Domain-Specific Scripts

Scripts accessing domain logs or configuration should use these new variables:

• modules/website/ - All website analysis tools
• modules/email/ - Email delivery checks by domain
• modules/security/ - Domain-specific security scanning

Priority 2: PHP Version Detection

Scripts checking PHP versions should use these:

• modules/performance/php-*.sh - PHP performance analysis
• modules/website/website-slowness-diagnostics.sh - Framework detection

Priority 3: Control Panel Specific Tools

Any panel-specific features should reference these variables:

• cPanel API tools - Use domain config cache variables
• Plesk database tools - Use Plesk-specific paths
• InterWorx management - Use chroot paths
