webstats_common.lua - WebStats 统计系统核心模块
|
|||
|
|
==================================================
|
|||
|
|
|
|||
|
|
本模块提供 WebStats 系统的核心功能，包括：
|
|||
|
|
- 数据库连接管理
|
|||
|
|
- 日志数据处理与存储
|
|||
|
|
- 定时任务调度
|
|||
|
|
- 爬虫/客户端识别
|
|||
|
|
- IP/URL 统计
|
|||
|
|
|
|||
|
|
架构说明：
|
|||
|
|
1. 单例模式：通过 getInstance() 获取全局唯一实例
|
|||
|
|
2. 共享内存：使用 ngx.shared.mw_total 作为日志缓存队列
|
|||
|
|
3. SQLite 数据库：每个站点独立一个数据库文件
|
|||
|
|
4. 定时任务：每 0.5 秒执行一次日志持久化
|
|||
|
|
|
|||
|
|
主要数据流向：
|
|||
|
|
webstats_log.lua (日志采集) -> ngx.shared.mw_total (缓存队列) -> cron() (定时处理) -> SQLite (持久化)
|
|||
|
|
|
|||
|
|
依赖模块：
|
|||
|
|
- cjson: JSON 编解码
|
|||
|
|
- lsqlite3: SQLite 数据库操作
|
|||
|
|
- webstats_config: 全局配置
|
|||
|
|
- webstats_sites: 站点配置
