-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
--   redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:

编译原则

1. 确定 的功能一定编译进内核
2. 可能 的功能编译为模块
3. 不确定 的功能保留默认值，或编译为模组
4. 选择 双号 版本内核，忽略 单号 内核
