连接redis集群需要用到ua-resty-redis-cluster模块

github地址：

下载完成后，只需要用到包中2个文件和

.c文件无法在nginx配置文件中引入，需要编译成.so文件，编译命令：  gcc SOURCE_FILES -fPIC -shared -o TARGET

如下则是连接redis集群代码：

local config = {                name = "test",                serv_list = {                    {ip="127.0.0.1", port = 3100},                    {ip="127.0.0.1", port = 3101},                    {ip="127.0.0.1", port = 3102},                    {ip="127.0.0.1", port = 3200},                    {ip="127.0.0.1", port = 3201},                    {ip="127.0.0.1", port = 3202},                },            }            local redis_cluster = require "resty.rediscluster"            local red = redis_cluster:new(config)            for i = 1, 2 do                red:init_pipeline()                red:set("dog", "an animal")                red:get("dog")                red:set("dog", "hello")                red:get("dog")                local results = red:commit_pipeline()                local cjson = require "cjson"                ngx.say(cjson.encode(results))            end            red:close()
