*Redis 模块

Redis Modules System是4.0出现一大改动点，使得可以通过外部模块对Redis进行功能性扩展。 Redis的模块采用的是动态链接库的方式，可以启动的时候加载，也可以在运行时加载（MODULE LOAD）,在Linux系统里面，可以通过dlopen，dlsym等实现动态加载库，在业务系统里面，经常用于将业务代码和框架代码进行分离，以实现插件化开发。在Redis里面也是同样的道理。要实现分离，首先需要的是初始化，以便让框架可以找到对应的方法，这就需要进行注册，Redis通过RedisModule_Init方法进行注册模块，和RedisModule_CreateCommand注册自定义方法。

Redis导出了redismodule.h头文件，通过实现该头文件相关API函数，然后编译为so动态库即可，可以在配置文件中使用loadmodule指明，也可以在运行时使用命令动态加载（MODULE LOAD）。

Redis 模块列表，适用于 redis v4.0 或更高版本，以 Github stars 数量排序。此列表包含两组模块：OSI许可证下的模块和某些专有许可证下的模块。非OSI模块被明确标记为非开源。
