LLStack Compatibility Matrix

Backend Scope

Capability Apache OpenLiteSpeed LiteSpeed Enterprise
ServerName / ServerAlias implemented compiled apache-style + extension
docroot implemented compiled native-like
index implemented compiled native-like
access/error log implemented compiled native-like
TLS basic implemented compiled native-like
rewrite basic implemented compiled with parity report native-like
reverse proxy basic implemented compiled basic context mapping feature-gated
per-site PHP binding implemented via php-fpm via extprocessor via lsphp-compatible adapter
Apache direct config consumption yes no partial / extended
parity report required low mandatory mandatory

OpenLiteSpeed 当前降级项：

  • HeaderRule: degraded
  • AccessControlRule: degraded
  • parity report 已输出 JSON，但粒度仍是 feature 级，不是逐指令 diff

LiteSpeed Enterprise 当前能力：

  • trial / licensed / unknown 检测：implemented
  • directive injection：implemented
  • enterprise feature flags：implemented
  • 真实服务级验证：pending

PHP Scope

目标版本：

  • 8.2
  • 8.3
  • 8.4

保留兼容考虑：

  • 8.1
  • 未来 8.5

约束：

  • 使用 Remi php-litespeed
  • 不使用 LiteSpeed 官方 lsphp 安装链路
  • Apache backend 使用 php-fpm
  • OLS / LSWS 的 PHP adapter 以 Remi php-litespeed 为主

当前状态：

  • 多版本 runtime model：implemented
  • per-site PHP switch：implemented
  • extension install plan：implemented
  • php.ini profiles：implemented

Site Lifecycle Scope

Capability Status Notes
deploy profiles implemented generic / wordpress / laravel / static / reverse-proxy
scaffold starter files implemented profile-specific docroot starter assets
drift preview implemented site:diff compares managed assets with canonical render
site start/stop implemented toggles managed backend asset paths between active and .disabled targets
site reload implemented backend configtest + reload
site logs implemented access/error tail read
custom TLS update implemented rewrites site config and manifest
Let's Encrypt flow partial certbot --webroot orchestration + binary detection + test skeleton exist, real ACME validation pending

Database Scope

Provider Install Init TLS State Create DB/User Notes
MariaDB implemented implemented implemented implemented 与 MySQL/Percona 共享较多抽象
MySQL implemented implemented implemented implemented 默认假定 vendor repo 已配置
Percona Server implemented implemented implemented implemented 默认假定 vendor repo 已配置
PostgreSQL implemented implemented implemented implemented required TLS 仍需 pg_hba.conf 配合

Cache Scope

Provider Install Health Check Notes
Memcached implemented pending 已纳入 service component model
Redis implemented pending Phase 6 初版已纳入统一 provider model

Degradation Rules

  • OLS / LSWS 不支持的能力必须写入 parity report
  • CLI / TUI 必须提示 degraded / unsupported
  • 不允许用户以为“完全兼容 Apache”而实际静默丢失能力
