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 ?php 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 ?php 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 its going to take a long time, periodically // tell beanstalk were alive to stop it rescheduling the job. $pheanstalk-touch($job); sleep(2); // eventually were 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
extensionbeanstalk 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 ?php
$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tubeadelete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 ?phprequire __DIR__ . /vendor/autoload.php;
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
?php $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 $start microtime( true ); for ($i0; $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 下载并安装 cygwin
1. 添加镜像地址 - http://mirrors.aliyun.com 2. 下载 gcc、gcc-core、make、automake, 在 Devel 分支下 下载 beanstalkd-win 包
1. 解压并进入beanstalkd-win目录 2. 打开CMD窗口,运行 ./beanstalkd.exe -l 127.0.0.1 -p 11300
