项目分为Linux下和Window下，因为系统跑在Linux下所以Demo为Linux版，官网上有Window的版本。

页面端：

将项目放在Linux下随意目录下，不必非要放在apache和Nginx下。

php ws_test.php start

将html页面放在apache下。在浏览器端打开即可。

踩坑：

PHP Fatal error:  Call to undefined function Workerman\posix_getpid() in /var/temp/WebSocket03/Workerman/Worker.php on line 1908Fatal error: Call to undefined function Workerman\posix_getpid() in /var/temp/WebSocket03/Workerman/Worker.php on line 1908
