用lua+redis实现一个简单的计数器功能（二）

环境已经搭建完毕传送门

计数方案

　　就目前来看nginx是最快的服务

　　我在设计方案时选择信任redis作为存储库，不做穿透处理，由于目前redis集群方案还不成熟，只在这里做了主备方案。想做集群方案的人可以考虑使用twemproxy

　　--如采用twemproxy 集群方案不要选择信任redis集群，最好有穿透机制一旦某机器当机，恢复会很麻烦

为方便管理lua文件，修改nginx.conf并重启

lua_package_path '/var/www/lib/?.lua';

init_by_lua_file '/usr/local/nginx/lua/init.lua';#将配置文件加载到nginx内存中
