Seeker

Seeker是一个基于Swoole实现的服务架构整体实现

---

实现服务

• Master:负责管理所有节点
• Node:用于管理该节点下所有的Service
• ServiceProcess:运行具体的业逻辑
• Harbor:用于转发协议，连接所有Node.

LIST

• CLI命令行管理Master, 增加节点，发布service process ....
• 并行远程service调用
• 对发Node发出的协议 超时管理
• HTTP异步下载文件，用于节点收到发布任务时 进行下载执行源码或是文件
• .....
• ConnectClient向Node 进行协议注册
• 消息分发器
• 远程调用
• .....

启动Master

php ./bin/launcher.php --host=0.0.0.0 --port=9901 --type=master

启动Node

php ./bin/launcher.php --host=0.0.0.0 --port=9901 --type=node

启动Harbor

php ./bin/launcher.php --host=0.0.0.0 --port=9901 --type=harbor

开发时启动Service process

需要将目录切换到seeker的上次目录。

php ./seeker/bin/service.php --process=user --version=2.0.1 --vendor=./vendor --debug-user=./seeker/bin/demo/user/2.0.1 --debug-widget-demo=./seeker/bin/demo/widget_demo/1.0.0 --host=0.0.0.0 --port=9901 --key=894e6d6e55a41bfdd0603edfb1eb41a7 --id=10000

Service 示例

namespace Seeker\Service\Master;

use Seeker\Sharded;
use Seeker\Manager\NodeClient;
use Seeker\Protocol\Error;
use Seeker\Service\Common\Base;

class Deploy extends Base
{
    //节点认证
    public function progress()
    {
        //找到相应的Node...
        $nodeId = $this->request->getFromNode();
        $progress = $this->request->get('progress');
        $taskId = $this->request->get('taskId');

        print_r($this->request);

        echo 'Deploy Progress:' . sprintf('N:%d, T:%s, %d%%'
            , $nodeId
            , $taskId
            , $progress
        ) . PHP_EOL;
    }
}

调用别的Service 示例

$this->dispatcher->remoteCall('common.node.login')
    ->setToNode($this->nodeId)
    ->set('type', 'master')
    ->set('authKey', $this->authKey)
    ->then(function($connection, $response) {
        if (!$response->getCode()) {
            $connection->setAuthed(static::AUTHED_COMMON | static::AUTHED_NODE);
        } else {
            $connection->close();
        }
    })
    ->sendTo($this);
