shell模拟php多进程从redis获取数据(多个redis实例)

﹏ヽ暗。殇╰゛Y 2023-10-17 17:48 55阅读 0赞

背景:现在的数据已经写到了redis队列里面，完成了入栈的操作，后期打算从redis获取数据，完成出栈的操作，出栈后然后做一系列的逻辑处理  
  
环境: VMware虚拟机 内存:1G 硬盘:60G php环境:PHP Version 5.6.31 php框架:TP

测试:事先在redis里面插入了30W条数据，分别模拟php单进程和多进程(3个多进程)

php单进程代码:

public function sinsert() \{  
//$redis = new Redis();  
//$redis->connect('127.0.0.1', 6379);  
//写到list类型缓存里面  
//lpush('zc\_hk\_list', serialize($zc\_hk))  
//$accountRepayModel = D('AccountRepay');  
$this->repay->start();  
for($i=1;$i<=300000;$i++) \{  
$arr = array("k"=>$i,"v"=>"dan".$i);  
//var\_dump($arr);//exit;  
$this->redis->lpush('hongniu', serialize($arr));  
\}  
$this->repay->stop();  
$spent\_time = $this->repay->spent($echo=true, '全量写入redis数据发送脚本');  
$this->repay->clear();  
/\*$key = 'name';  
$value = $redis->get($key);  
var\_dump($value);\*/  
\}  
public function slist() \{  
$this->repay->start();  
$list\_len = $this->redis->llen('hongniu');  
Log::write('单进程一共有:'.$list\_len."条");  
  
if ($list\_len == 0) return;  
while (true) \{  
//$result = $this->redis->rpop('hongniu');  
$result = $this->redis->lpop('hongniu');  
if(empty($result)) \{break;\}  
$repayment\_data= unserialize($result);  
if(is\_array($repayment\_data) && !empty($repayment\_data)) \{  
//Log::write('多进程写日志的结果是1:'.json\_encode($repayment\_data));  
Log::write('单进程写日志的结果是:'.json\_encode($repayment\_data));  
\}  
\}  
$this->repay->stop();  
$spent\_time = $this->repay->spent($echo=true, '单进程导出redis数据脚本');  
$this->repay->clear();  
\}

php多进程代码:

public function binsert() \{  
//$redis = new Redis();

//var\_dump($arr);//exit;  
if($i%3==0) \{  
$this->redis->lpush('hongniu0', serialize($arr));

\}else\{  
$this->redis81->lpush('hongniu2', serialize($arr));  
\}  
\}  
$this->repay->stop();  
$spent\_time = $this->repay->spent($echo=true, '全量分别写入不同redis数据发送脚本');  
$this->repay->clear();  
/\*$key = 'name';  
$value = $redis->get($key);  
var\_dump($value);\*/  
\}  
public function blist1() \{

总结：因为redis是单进程单线程的，在只有一个redis实例的情况下，不管开启多少个进程，读取速度不会变快!

所以想要读取速度加快可以开启多个redis实例，写入的时候写入到多个redis实例中，读取的时候也是从多个redis实例读取。
