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rediscluster.lua和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()
