异步redis队列实现数据入库的方法

时间：2019-12-04来源：系统城作者：电脑系统城

业务需求

app客户端向服务端接口发送来json 数据每天发一次清空缓存后会再次发送

出问题之前业务逻辑：

php 接口首先将 json 转为数组去重在一张大表中插入不存在的数据

该用户已经存在和新增的id

入另一种详情表

问题所在：

当用户因特殊情况清除缓存导致app 发送json串入库并发高导致CPU 暴增到88% 并且居高不下

优化思路：

1、异步队列处理

2、redis 过滤（就是只处理当天第一次请求）

3、redis 辅助存储app名称（验证过后批量插入数据app名称表中）

4、拼接插入的以及新增的如详细表中

解决办法：

1、接口修改 redis 过滤 + 如list队列并将结果存入redis中

首先 redis将之前的历史数据放在redis 哈希里面中文为键名 id 为键值

<?php
/**
* Created by haiyong.
* User: jia
* Date: 2017/9/18
* Time: 20:06
*/
namespace App\Http\Controllers\App;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Redis;
class OtherAppController extends Controller{
/**
* app应用统计接口
* @param Request $request
* @return string
*/
public function appTotal(Request $request)
{
// //历史数据入库
//$redis = Redis::connection('web_active');
// $app_name = DB::connection('phpLog')->table('app_set_name')->where("appName", '<>', ' ')->lists('id', 'appName');
// $str = '';
// foreach ($app_name as $key => $val) {
// $str.= "{$val} {$key} ";
// }
// $redis->hmset('app_name', $app_name);
// echo $str;exit;
$result = $request->input('res');
$list = json_decode($result, true);
if (empty ($list) || !is_array($list)) {
return json_encode(['result' => 'ERROR', 'msg' => 'parameter error']);
}
$data['uid'] = isset($list['uid']) ? $list['uid'] : '20001' ;
$data['time'] = date('Y-m-d');
$redis_key = 'log_app:'.$data['time'];
//redis 过滤
$redis = Redis::connection('web_active');
//redis 键值过期设置
if (empty($redis->exists($redis_key))) {
$redis->hset($redis_key, 1, 'start');
$redis->EXPIREAT($redis_key, strtotime($data['time'].'+2 day'));
}
//值确定
if ($redis->hexists($redis_key, $data['uid'])) {
return json_encode(['result' => 'SUCCESS']);
} else {
//推入队列
$redis->hset($redis_key, $data['uid'], $result);
$redis->rpush('log_app_list', $data['time'] . ':' . $data['uid']);
return json_encode(['result' => 'SUCCESS']);
}
}
}

2、php 脚本循环监控redis 队列执行逻辑防止内存溢出

mget 获取该用户的app id 不存在就会返回null

通过判断null 运用redis 新值作为自增id指针将null 补齐之后批量入mysql 并跟新redis 哈希和指针值并入库详情表

<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\Redis;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Storage;
class AppTotal extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'AppTotal:run';
/**
* The console command description.
*
* @var string
*/
protected $description = 'Command description';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
//历史数据入库
// $redis = Redis::connection('web_active');
// $app_name = DB::connection('phpLog')->table('app_set_name')->where("appName", '<>', ' ')->lists('id', 'appName');
// $redis->hmset('app_name', $app_name);
// exit;
while(1) {
$redis = Redis::connection('web_active');
//队列名称
$res = $redis->lpop('log_app_list');
//开关按钮
$lock = $redis->get('log_app_lock');
if (!empty($res)) {
list($date,$uid) = explode(':',$res);
$result = $redis->hget('log_app:'.$date, $uid);
if (!empty($result)) {
$table_name = 'app_total'.date('Ym');
$list = json_decode($result, true);
$data['uid'] = isset($list['uid']) ? $list['uid'] : '20001' ;
$data['sex'] = isset($list['sex']) ? $list['sex'] : '' ;
$data['device'] = isset($list['device']) ? $list['device'] : '' ;
$data['appList'] = isset($list['list']) ? $list['list'] : '' ;
//数据去重 flip比unique更节约性能
$data['appList'] = array_flip($data['appList']);
$data['appList'] = array_flip($data['appList']);
$data['time'] = date('Y-m-d');
//app应用过滤
$app_res = $redis->hmget('app_name', $data['appList']);
//新增加app数组
$new_app = [];
//mysql 入库数组
$mysql_new_app = [];
//获取当前redis 自增指针
$total = $redis->get('app_name_total');
foreach ($app_res as $key =>& $val) {
if (is_null($val)) {
$total += 1;
$new_app[$data['appList'][$key]] = $total;
$val = $total;
array_push($mysql_new_app,['id' => $total, 'appName'=> $data['appList'][$key]]);
}
}
if (count($new_app)){
$str = "INSERT IGNORE INTO app_set_name (id,appName) values";
foreach ($new_app as $key => $val) {
$str.= "(".$val.",'".$key."'),";
}
$str = trim($str, ',');
//$mysql_res = DB::connection('phpLog')->table('app_set_name')->insert($mysql_new_app);
$mysql_res = DB::connection('phpLog')->statement($str);
if ($mysql_res) {
// 设置redis 指针
$redis->set('app_name_total', $total);
// redis 数据入库
$redis->hmset('app_name', $new_app);
}
}
// 详情数据入库
$data['appList'] = implode(',', $app_res);
//app统计入库
DB::connection('phpLog')->statement("INSERT IGNORE INTO ".$table_name." (uid,sex,device,`time`,appList)
values('".$data['uid']."',".$data['sex'].",'".$data['device']."','".$data['time']."','".$data['appList']."')");
//log 记录当文件达到123MB的时候产生内存保错所有这个地方可是利用日志切割或者不写入日志
Storage::disk('local')->append(DIRECTORY_SEPARATOR.'total'.DIRECTORY_SEPARATOR.'loaAppTotal.txt', date('Y-m-d H:i:s').' success '.$result."\n");
} else {
Storage::disk('local')->append(DIRECTORY_SEPARATOR.'total'.DIRECTORY_SEPARATOR.'loaAppTotal.txt', date('Y-m-d H:i:s').' error '.$result."\n");
}
}
//执行间隔
sleep(1);
//结束按钮
if ($lock == 2) {
exit;
}
//内存检测
if(memory_get_usage()>1000*1024*1024){
exit('内存溢出');//大于100M内存退出程序，防止内存泄漏被系统杀死导致任务终端
}
}
}
