[openresty]第三节:操作redis数据

同样的看redis组件

https://github.com/openresty/lua-resty-redis

按照实例添加redis.conf

worker_processes 1;
error_log logs/error.log;
events {
worker_connections 1024;
}
http {
server {
listen 8091;
location / {
default_type text/html;
content_by_lua_block {
local redis = require "resty.redis"
local red = redis:new()

red:set_timeout(1000)
local ok,err = red:connect("127.0.0.1", 6379)
if not ok then
ngx.say("fail to connent", err)
return
end

local res,err = red:get("lua")
if not res then
ngx.say("failed to get lua", err)
return
end
ngx.say(res)
}
}
}
}

启动redis.conf配置

../nginx/sbin/nginx -p `pwd`/ -c conf/redis.conf

访问localhost:8091 获取了key为lua的数据，使用起来非常简单。
