--连接池大小,最大的空闲时间 redis:set_keepalive(redisKeepaliveSize, redisMaxRestTime) 我们是在什么情况下使用的keepalive: keepalive是在redis已经建立了连接,并进行相关值请求以后执行的!!! 我们在使用lua连接redis的时候,期望它自身具备以下几个特征: new、connect 函数合体,使用时只负责申请,尽量少关心什么...
2. 设置keepalive 接下来设置keepalive参数,保持redis连接长期有效。可以使用以下Lua代码实现: -- 设置keepalive local ok, err = red:set_keepalive(10000, 100) if not ok then ngx.say("failed to set keepalive: ", err) return end 1. 2. 3. 4. 5. 6. 3. 失败报错 如果设置keepalive失败,需...
set_keepalive syntax: ok, err = red:set_keepalive(max_idle_timeout, pool_size) 将当前redis链接放入ngx_lua cosocket链接池,可以设置连接的最大空闲时间和每个nginx工作进程的池的最大数 如果成功返回1,如果错误返回nil,并返回错误描述 注:这个方法用户替代close方法,调用该方法后,redis链接变为关闭状态,除...
I encountered a problem when I set keepalive to redis while using ngx.redirect. My intent is to keep the connection between nginx and redis always established so that I can reduce the cost on TCP connection while I can do query in redis ...
3、使用redis连接池 local ok, err = red:set_keepalive(60000, 20) 4、需要密码的redis的访问:使用 auth 方法 local ok, err = red.connect(red, "127.0.0.1", "6379") if not ok then return end local res, err = red:auth("password") if not res then return end ...
function RedisOption.close_redis(red)if not red then return end local pool_max_idle_time = 10000 local pool_size = 100 local ok, err = red:set_keepalive(pool_max_idle_time, pool_size)local log = ngx_log if not ok then log(ngx_ERR, "set redis keepalive error : ", err)end end...
我自己下面的代码是利用 coroutine, 每次当前 phase 结束后自动调用 set_keepalive localredis =require"resty.redis"localM = {}localfunctionset_keepalive(p, red, opts)whiletruedoif'dead'==coroutine.status(p)thenbreakendngx.sleep(0.01)endok, err = red:set_keepalive(opts.freetime, opts.poolsize)...
local pool_max_idle_time=10000local pool_size=100red:set("pool_size",pool_size)local ok,err=red:set_keepalive(pool_max_idle_time,pool_size)ifnot ok thenngx_log(ngx_ERR,"set redis keepalive error : ",err)end end local uri=ngx.var.urired:set_timeout(1000)red:connect("119.23.46.71...
set _ keepalive ( self , local sock rawget ( self ,"_ sock ") if not sock then retarn nil ," not initialized ” end 4.调用命令 现在数据中有一个 heima 值是 verygood, 直接调用 redis,key 是 heima, 获取数据也有可能成功和失败。这就是 redis 读取数据的实例 local ok , err =redis ...
I tried to check the "set_keepalive()" works or not by this way below : 1 nginx.conf location /lua { lua_code_cache off; content_by_lua_file /usr/local/nginx1.10.1/lua/access.lua; } 2 access.lua redis = require "redis" red = redis:new() ...
