Emdrive

此包提供了一个无限期运行的内建服务，允许按日或按间隔触发执行 Symfony\Component\Console\Command\Command

安装

打开命令控制台，进入您的项目目录，并执行以下命令以下载此包的最新版本

composer require maksslesarenko/emdrive

配置

emdrive:
    server_name: main # incase app is running on multiple servers this has to be unique
    pool_size: 5 # number of simultanious commands allowed to be execute
    tick_interval: 2000000 # interval in microseconds between service loop checks
    cmd_start: bin/console %s -vv -e prod > /dev/null 2>&1 & # template for scheduled commands to be executed with
    cmd_kill: kill -2 %s > /dev/null 2>&1 & # template for scheduled commands to be stopped with

    storage:
        dsn: '%env(DATABASE_URL)%' # dsn for mysql or sqlite database to store schedule

    lock: emdrive_lock # lock name that is configured in framework section
    pid_dir: var/pid # directory to store process ids for executed commands
    log_dir: var/elog # directory to store logs
    lock_dir: var/lock # directory to store lock files

framework:
    lock:
        enabled: true
        resources:
            emdrive_lock: flock
            #emdrive_lock: [flock, 'memcached://'] # incase multiple servers are used to run app

命令

bin/console emdrive:deploy # 主部署命令，检测其他部署命令并按顺序执行它们以部署包

bin/console emdrive:deploy:update-schedule # 更新计划的部署命令

bin/console emdrive:configure-schedule [<name>] # 更改命令计划时间/间隔

bin/console emdrive:service:run # 启动服务

bin/console emdrive:service:stop # 停止服务

bin/console emdrive:service:status [--watch] # 检查服务是否正在运行

bin/console emdrive:dump-schedule # 将计划输出到控制台

示例

+----+--------------------------+-------------+---------+---------------------+---------------------+---------------+----------------+
| Id | Name                     | Server name | Status  | Last start at       | Next start at       | Schedule type | Schedule value |
+----+--------------------------+-------------+---------+---------------------+---------------------+---------------+----------------+
| 1  | first-scheduled-command  | main        | stopped | 2018-04-06 23:19:01 | 2018-04-06 23:20:01 | interval      | 1 minutes      |
| 2  | second-scheduled-command | main        | stopped | 2018-04-06 23:05:00 | 2018-04-07 23:05:00 | time          | 23:05          |

创建计划命令

use Emdrive\Command\ScheduledCommandInterface;
use Emdrive\InterruptableExecutionTrait;
use Emdrive\LockableExecutionTrait;
use Symfony\Component\Console\Command\Command;

class FisrtScheduledCommand extends Command implements ScheduledCommandInterface
{
    use LockableExecutionTrait;
    use InterruptableExecutionTrait;

    public function configure()
    {
        $this->setName('first-scheduled-command');
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {        
        ...
        foreach ($collection as $item) {
            if ($this->isInterrupted()) {
                break;
            }
            ...
        }
    }
}

创建新的计划命令后，运行部署

bin/console emdrive:deploy

然后配置计划

bin/console emdrive:configure-schedule first-scheduled-command

Supervisord 配置

[program:emdrive]
command=/code/bin/console emdrive:service:run
stderr_logfile = /var/log/supervisor/emdrive.error.log
stdout_logfile = /var/log/supervisor/emdrive.log
stopsignal = INT
