添加入口文件
<?php
// +----------------------------------------------------------------------
// | ResQue执行入口文件
// +----------------------------------------------------------------------
// | 作者: Melody
// +----------------------------------------------------------------------
// [ PHP版本检查 ]
if (version_compare(PHP_VERSION, '5.5', '<')) {
die('PHP版本过低，最少需要PHP5.5，请升级PHP版本！');
}
fwrite(STDOUT, "Start init");
set_time_limit(0);
// [ 应用入口文件 ]
// 定义应用目录
define('APP_PATH', __DIR__ . '/application/');
define('MODE_NAME', 'cli'); // 自定义cli模式
// 处理自定义参数
$act = isset($argv[2]) ? $argv[2] : 'start';
putenv("Q_ACTION={$act}");
putenv("Q_ARGV=" . json_encode($argv));
// 加载框架引导文件
require './thinkphp/start.php';

/**

* 环境变量参数值：
* --queue|QUEUE: 需要执行的队列的名字
* --interval|INTERVAL：在队列中循环的间隔时间，即完成一个任务后的等待时间，默认是5秒
* --app|APP_INCLUDE：需要自动载入PHP文件路径，Worker需要知道你的Job的位置并载入Job
* --count|COUNT：需要创建的Worker的数量。所有的Worker都具有相同的属性。默认是创建1个Worker
* --debug|VVERBOSE：设置“1”启用更啰嗦模式，会输出详细的调试信息
* --pid|PIDFILE：手动指定PID文件的位置，适用于单Worker运行方式

创建Job处理类
示例创建的类为job/ComJob
<?php
/**
* Created by PhpStorm.
* User: melody
*/
namespace app\cisdi\job;
class ComJob
{
/**
* 任务执行函数
*/
public function perform()
{
$args = $this->args;
fwrite(STDOUT, json_encode($args) . '已处理完此信息' . PHP_EOL);
}
/**
* perform方法之前调用
*/
public function setUp()
{
// ... Set up environment for this job
}
/**
* perform方法之后调用
*/
public function tearDown()
{
// ... Remove environment for this job
}
}
添加任务示例
/**
* 测试添加消息队列
*/
public function testEnQueue(){
$job = '\\app\\cisdi\\job\\ComJob'; // 定义任务类
$args = array(
'time' => time(),
'array' => array(
'test' => 'test',
),
);
$jobId = \Resque::enqueue('default', $job, $args, true);
echo "Queued job ".$jobId."\n\n";
}
应用案例
- 创建任务
执行testEnQueue方法（可通过cli或者web端执行）
得到的返回信息：
Queued job fc7632470b1d7e69aede1675d79bdfe8
- 开启任务处理器
root@iZwz980sm1dapjhje7e6icZ:/home/wwwroot/default/wx_test# php resque.php cisdi/msg_queue/index start
Start init应用初始化开始
["resque.php","cisdi\/msg_queue\/index","start"]Start index 开始worker
地址/home/wwwroot/default/wx_test//application/cisdi/job/
*** Starting worker iZwz980sm1dapjhje7e6icZ:32471:*
{"time":1547713088,"array":{"test":"test"}}已处理完此信息
让应用长驻内存
- 安装supervisor
apt-get install supervisor
- 添加应用到supervisor
[program:resque]
command = php resque cisdi/msg_queue/index start &
numprocs=1
directory= 你的当前目录
stderr_logfile_maxbytes=10MB
stdout_logfile=/var/log/supervisor/%(program_name)s-stdout.log
stderr_logfile=/var/log/supervisor/%(program_name)s-stderr.log
redirect_stderr=true
autostart=true
autorestart=true
- 重启supervisor让配置文件生效
supervisorctl reload
- 启动应用进程
supervisorctl start
