这篇文章我们继续分析BaseServer的启动相关的方法，这里先分析BaseServer的initRunTime方法，这里很多都是前面配置信息设置到BaseServer对象的属性中，字段也比较明确，不再展开太具体的分析。

//初始化运行环境，runPath值为/var/fsof/provider
public function initRunTime($runPath)
	{
		if (!empty($runPath))
		{
			$this->runPath = $runPath;
		}

    	//记录master进程号和manager进程号
        $this->masterPidFile =  $this->runPath.DIRECTORY_SEPARATOR.$this->processName.'.master.pid';
        $this->managerPidFile = $this->runPath.DIRECTORY_SEPARATOR.$this->processName.'.manager.pid';
        FileSystemUtil::makeDir(dirname($this->masterPidFile));
        
        //获取app的服务信息
		$services = isset($this->config['service_providers']) ? $this->config['service_providers'] : array();
		if (empty($services))
		{
            $this->logger->error($this->processName.".provider's service_providers is empty");
			exit(1);
		}

		foreach($services as $interface => $serviceInfo)
		{
			$this->serverProviders[$interface] = $serviceInfo;
		}

        $this->logger->info("services list:" . json_encode($this->serverProviders));
        
        //增加application, language, environment, set, owner, group信息等信息
        $this->config["service_properties"]["application"] = $this->processName;
        $this->config["service_properties"]["language"] = "php";
        //$this->config["service_properties"]["application_version"] = $this->deployVersion;
        if (empty($this->config["service_properties"]["owner"]))
        {
            $this->config["service_properties"]["owner"]  = $this->processName;
        }

        //swoole setting
        $runSetting = isset($this->config['setting']) ? $this->config['setting'] : array();
        $this->setting = array_merge($this->setting, $runSetting);

        //过载保护配置

		}

		//加载连续过载次数
		if (isset($this->setting['overload_number']))
		{
			$this->config['fsof_setting']['overload_number'] = $this->setting['overload_number'];
		}

		}

        //main setting
        $mainSetting = isset($this->config['server']) ? $this->config['server'] : array();

        // trans listener
        if (isset($mainSetting['listen']))
        {
            $this->transListener($mainSetting['listen']);
