连接redis集群需要用到llua-resty-redis-cluster模块

github地址：https://github.com/cuiweixie/lua-resty-redis-cluster

下载完成后，只需要用到包中2个文件redis_slot.c

.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()
