lua_shared_dict使用，报500

phponcer

将redis缓存换成lua_shared_dict 报500错误 errlog无日志，第一次使用shared，见谅，谁帮分析，谢谢。

nginx.conf配置中配置

lua_shared_dict dogs 10m;

lua_code_cache off ; //on

test.lua

代码

local mysql = require "resty.mysql"
local luastring = require "resty.string"
local print = ngx.print
local ngx_null 	= ngx.null

local ngx_time  = ngx.time()  --os.time()¸
local tostring      = tostring
local tonumber      = tonumber

local cjson = require "cjson"

local dogs = ngx.shared.dogs

dogs:flush_all()
local body,flags = dogs:get("key2")

local res = body
--local res=ngx.null
if 1==1 then
	local db, err = mysql:new()
	if not db then
		ngx.say("failed to instantiate mysql: ", err)
		return
	end

	db:set_timeout(1000) -- 1 sec
	local ok, err, errno, sqlstate = db:connect{
			 host = "127.0.0.1",
			 port = 3306,
			 database = "mysql",

			 password = "root",
			 max_packet_size = 1024 * 1024 }

				 return
			 end
	 res, err, errno, sqlstate =
	 db:query("select * from mysql.user limit 100", 10)
	 if not res then
		 ngx.say("bad result: ", err, ": ", errno, ": ", sqlstate, ".")
		 return

	 local res=cjson.encode(res) 

	local body=res

改的惨不忍睹，格式化了代码。

你注意下 error_log 配置级别是否太高了，比如到了 CRIT？

这代码实在太乱了，还是找 error_log 出来看吧，我是看不下去了，哈哈 :)
