2. Write test scripts

sendEmail.phpThe code is as follows:

workload(), true); //这里模拟处理过程 //具体的业务，这里应该是请求发送邮件的接口，这里只做演示 sleep(1); echo "workId: {$workId} 发送 {$data['email']} 成功\n"; }

client.phpThe code is as follows:

addServer('127.0.0.1', 4730); $cnt = 5000; $ret = array(); //循环发送5000条邮件 for($i = 0; $i < $cnt; ++$i) { //doBackground异步，返回提交任务的句柄 $ret[$i] = $client->doBackground('sendEmail', json_encode(array( 'email' => "{$i}@qq.com", 'title' => "邮件标题{$i}", 'body' => "我是内容{$i}", ))); }

3. Modify the configuration information in gearmanManager

My gearmanManager is installed under /data/GearmanManager/

> vi /data/GearmanManager/etc/GearmanManager.ini

Add the following information, we start five processes for sendEmail

[sendEmail] ;指定5个进程 dedicated_count=5 ;5个进程都只做sendEmail工作 dedicated_only=1

4. Start gearman

> gearmand -d -q mysql \ --mysql-host=192.168.1.100 \ --mysql-port=3306 \ --mysql-user=gearman \ --mysql-password=123456 \ --mysql-db=gearman \ --mysql-table=gearman_queue &

5. Start gearmanManager

> cd /data/GearmanManager > ./bin/pecl_manager.php -c /data/GearmanManager/etc/GearmanManager.ini -vvv

##6. Run client.php

> /data/php56/bin/php /data/client.php

When we restart the worker, gearman will reload the unprocessed ones for processing.

My mysql is installed on the host machine, and gearman is installed on the virtual machine. If any friends find that gearman cannot connect to mysql, they can temporarily turn off the win10 firewall and enable the ping response of win10. Show.
