lua-nginx-module : 该模块是 OpenResty 的核心组件,目录是将lua的功能嵌入到Nginx http服务器中。 lua-resty-redis : 该模块是在 OpenResty 项目下基于 cosocket API 的 ngx_lua 的 Lua redis 客户端驱动。 温馨提示: 如果不是现有业务大量使用Nginx进行承载不能直接替换其它优秀的解决方案,只能一步一步来,从而...

Theresty.websocketobject instance cannot be stored in a Lua variable at the Lua module level, because it will then be shared by all the concurrent requests handled by the same nginx worker process (seehttp://wiki.nginx.org/HttpLuaModule#Data_Sharing_within_an_Nginx_Worker) and result in bad...
