使用swoole http server（生产环境不建议使用）

ps:对性能有要求的同学，届时请关照Group的异步协程版本，极大降低i/o阻塞带来的等待，支持高并发。 [猛戳](https://github.com/fucongcong/Group-Co)

1.配置文件在config/app.php

2.nginx配置文件示例在最下方

3.执行php server.php &

4.访问http://127.0.0.1:9776

5.压测。测试机:mac mini 双核8G。

附nginx 配置：

server {

    listen 9776;
    root /var/www/Group;
    //server_name local.swoole.com;


    location / {
        try_files $uri @rewriteapp;
    }
    location @rewriteapp {
        rewrite ^(.*)$ /index.php$1 last;
    }
    location ~ ^/(index)\.php(/|$) {
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $host;
        proxy_pass http://127.0.0.1:9777;
    }

    location ~* \.(jpg|jpeg|gif|png|ico|swf)$ {
        # 过期时间为3年
        expires 3y;

        # 关闭日志记录
        access_log off;

        # 关闭gzip压缩，减少CPU消耗，因为图片的压缩率不高。
        gzip off;
    }

    # 配置css/js文件
    location ~* \.(css|js)$ {
        access_log off;
        expires 3y;
    }
}
