BeansTalkd 做消息队列服务

无意间看到这个仓库讲php关于 BeanStalkd 的扩展,然后就去了解了一下beanstalkd,用它可以用来做队列服务。

话不多说,安装一下试试。

首先 sudo apt search beanstalk 搜索一下发现

好了,找到这个beanstalkd了

然后安装

 sudo apt-get install beanstalkd

安装成功,这个东西会监听 11300 端口
然后使用这个工具来看看


监控工具:

wget https://github.com/src-d/beanstool/releases/download/v0.2.0/beanstool_v0.2.0_linux_amd64.tar.gz

获取文件后解压

tar -xvzf beanstool_v0.2.0_linux_amd64.tar.gz

然后拷贝到 /usr/local/bin/

sudo cp beanstool_v0.2.0_linux_amd64/beanstool /usr/local/bin/

这样就直接用 beanstool 了

查看当前状态

beanstool stats

结果

+---------+----------+----------+----------+----------+----------+----------+----------+
| Name    | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+---------+----------+----------+----------+----------+----------+----------+----------+
| default | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
+---------+----------+----------+----------+----------+----------+----------+----------+

然后使用composer的vendor包

composer require pda/pheanstalk
安装完毕后创建一个input.php文件做生产者


require __DIR__ . '/vendor/autoload.php';

use Pheanstalk\Pheanstalk;

$pheanstalk = Pheanstalk::create('127.0.0.1');

// Queue a Job
$pheanstalk
  ->useTube('testtube')
  ->put("job payload goes here\n");

$pheanstalk
    ->useTube('testtube')
    ->put(
        json_encode(['test' => 'data']),  // encode data in payload
        Pheanstalk::DEFAULT_PRIORITY,     // default priority
        30, // delay by 30s
        60  // beanstalk will retry job after 60s
     );


再创建一个output.php文件做消费者


require __DIR__ . '/vendor/autoload.php';
use Pheanstalk\Pheanstalk;

$pheanstalk = Pheanstalk::create('127.0.0.1');

// we want jobs from 'testtube' only.
$pheanstalk->watch('testtube');

// this hangs until a Job is produced.
$job = $pheanstalk->reserve();

try {
    $jobPayload = $job->getData();
    // do work.

    sleep(2);
    // If it's going to take a long time, periodically
    // tell beanstalk we're alive to stop it rescheduling the job.
    $pheanstalk->touch($job);
    sleep(2);

    // eventually we're done, delete job.
    $pheanstalk->delete($job);
}
catch(\Exception $e) {
    // handle exception.
    // and let some other worker retry.
    $pheanstalk->release($job); 
}
 

然后执行一下  php input.php

查看 状态

 
$ beanstool stats
+----------+----------+----------+----------+----------+----------+----------+----------+
| Name     | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+----------+----------+----------+----------+----------+----------+----------+----------+
| default  | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
| testtube | 0        | 1        | 1        | 0        | 0        | 0        | 2        |
+----------+----------+----------+----------+----------+----------+----------+----------+
 
我们看到有一个在ready状态,一个在delayed状态,这是由于第二次的put采用了延时30s,然后过一段时间后再看

 
$ beanstool stats
+----------+----------+----------+----------+----------+----------+----------+----------+
| Name     | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+----------+----------+----------+----------+----------+----------+----------+----------+
| default  | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
| testtube | 0        | 0        | 2        | 0        | 0        | 0        | 2        |
+----------+----------+----------+----------+----------+----------+----------+----------+
复制代码
已经有2个在ready状态了。

此时我们用消费者执行一下 php output.php 

与此同时迅速看状态

复制代码
$ beanstool stats
+----------+----------+----------+----------+----------+----------+----------+----------+
| Name     | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+----------+----------+----------+----------+----------+----------+----------+----------+
| default  | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
| testtube | 0        | 0        | 1        | 1        | 0        | 0        | 2        |
+----------+----------+----------+----------+----------+----------+----------+----------+
再次执行
$ beanstool stats
+----------+----------+----------+----------+----------+----------+----------+----------+
| Name     | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+----------+----------+----------+----------+----------+----------+----------+----------+
| default  | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
| testtube | 0        | 0        | 1        | 0        | 0        | 0        | 2        |
+----------+----------+----------+----------+----------+----------+----------+----------+
复制代码
因为我们有sleep(2),所以要尽量快点操作这个状态监控的命令,可以看到有一个拿出来放入了reserved,然后就消失了(实际上这是后面的代码delete导致的,因为已经消费完毕)

再次执行 php output.php 

 
$ beanstool stats:
+----------+----------+----------+----------+----------+----------+----------+----------+
| Name     | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+----------+----------+----------+----------+----------+----------+----------+----------+
| default  | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
| testtube | 0        | 0        | 0        | 1        | 0        | 0        | 2        |
+----------+----------+----------+----------+----------+----------+----------+----------+

$ beanstool stats:
+---------+----------+----------+----------+----------+----------+----------+----------+
| Name    | Buried   | Delayed  | Ready    | Reserved | Urgent   | Waiting  | Total    |
+---------+----------+----------+----------+----------+----------+----------+----------+
| default | 0        | 0        | 0        | 0        | 0        | 0        | 0        |
+---------+----------+----------+----------+----------+----------+----------+----------+
 
同样也是迅速观测这个状态,发现消费1个,然后删除1个,现在队列空了,这说明确实是符合我们的期望的。

然后回到文章开头提到的扩展,这个扩展就是帮我们实现了composer装的那个pheanstalk包。


这个扩展如何安装呢?

步骤如下:

克隆项目

git clone https://gitee.com/qzfzz/php-beanstalk.git
进行编译 

phpize

然后

./configure

之后

make && make install

sudo make install

然后修改 php.ini

sudo gedit /etc/php/7.4/cli/php.ini /etc/php/7.4/apache2/php.ini

加上这句

extension=beanstalk

重启apache2

sudo /etc/init.d/apache2 restart
之后就可以使用这个扩展了。

这个扩展它封装为函数了,可以看到他有个例子文件

简单的找了几个例子

复制代码

$config = [
  'host' => '127.0.0.1',
  'port' => 11300
];
$beanstalk_obj = beanstalk_connect($config['host'], $config['port']);
$last_job_id = beanstalk_put($beanstalk_obj, "message detail");
beanstalk_delete($beanstalk_obj, $last_job_id);
$last_job_id = beanstalk_putInTube($beanstalk_obj, 'tubea', "message detail");
复制代码
可以看到使用 connect 连接, put 塞入新的job消息, putInTube 来塞入指定管道的tubea,delete来删除等等,具体可以看看源代码学习一下,我对比了一下这两种方式实现效率。

第一种采用composer包(我还特意去掉了加载文件所需要的时间)

复制代码

use Pheanstalk\Pheanstalk;

$start = microtime( true );
$pheanstalk = Pheanstalk::create('127.0.0.1');

$pheanstalk
  ->useTube('testtube')
  ->put(date("Y-m-d H:i:s") . "job payload goes here\n");

$end = microtime(true);

echo ($end - $start) * 1000 . " ms";
复制代码
执行需要2.59ms

第二种直接用扩展函数


$start = microtime(true);

$config = [
  'host' => '127.0.0.1',
  'port' => 11300
];

$beanstalk_object = beanstalk_connect($config['host'], $config['port']);
$last_job_id = beanstalk_putInTube($beanstalk_object, 'testtube', date("Y-m-d H:i:s") . "job payload goes here\n");

$end = microtime(true);

echo ($end - $start) * 1000 . " ms";
复制代码
执行需要0.34ms

不得不说,扩展就是扩展,就是快的多啊!

我另外测试了一下投递极限

循环投递10000次消息,大概在500ms左右

复制代码
$start = microtime( true );
for ($i=0; $i < 10000; $i++) { 
  $pheanstalk
  ->useTube('testtube')
  ->put(date("Y-m-d H:i:s") . "job payload goes here\n");
}
$end = microtime( true );
echo ($end - $start) * 1000 . " ms";


 
也就意味着1秒钟只能投递20000条消息,这比rabbitmq的投递慢多了(参见这篇文章)

但是它执行1次投递消息的时候却比这个rabbitmq的代码执行的快,原因是我测试了一下这个rabbitmq的连接上就耗费了9ms

$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');

更别提还有这两步了

$channel = $connection->channel();
$channel->queue_declare('hello', false, false, false, false);
这样来看,想迅速投递一条短消息,或者建立小信息量的job用beanstalk是很不错的,如果有大量消息集中投递,那使用 rabbitmq 是很不错的。

另外这个beanstalk投递可以延时,非常适合有些时候需要在当前时间一段时间后执行某个任务,往后弄个类似于一次性的定时器的功能,这个东西值得尝试。

而且如果使用while死循环将 output.php 脚本一直挂着跑,它就能一直消费消息了,这样就等于有个后端进程一直能帮我们做消费者处理堆积的任务了,特殊场景可以考虑一下这个方案。

Windows 安装 Beanstalkd
