redis 集群如何使用lua redis集群对lua的支持

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

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

下载完成之后，只需要用到包中的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

# centos自带lua需要执行此命令再编译，自己安装过lua不需要
yum install lua-devel

#编译命令
gcc redis_slot.c -fPIC -shared -o libredis_slot.so

[hadoop@slave2 lualib]$ ls
cjson.so  libredis_slot.so  lua2redis.lua  ngx  rds  redis  redis_slot.c  resty

如下是连接redis集群代码:

local config = {
                name = "test",
                serv_list = {
                    {ip="192.168.28.100", port = 7001},
                    {ip="192.168.28.100", port = 7002},
                    {ip="192.168.28.100", port = 7003},
                    {ip="192.168.28.100", port = 7004},
                    {ip="192.168.28.100", port = 7005},
                    {ip="192.168.28.100", port = 7006},
                },
            }
            local redis_cluster = require "resty.rediscluster"
            local red = redis_cluster:new(config)
            red:set("s1", "1000")
            red:get("s1")
            red:close()
