1，关于pagespeed

---

是一个 google的 pagespeed 优化页面nginx 模块。
能够压缩html css js 图片，自动优化网页。
超级厉害呢。
项目地址：
https://www.modpagespeed.com
GitHub：
https://github.com/apache/incubator-pagespeed-ngx
已经放到apache 孵化器里面了。

2，构建dockerfile

---

docker已经非常的流行了。
给出dockerfile 别人就能一样构建出环境。
超级喜欢。

    --with-http_sub_module  --with-http_stub_status_module  --with-http_v2_module && \
    make && make install && rm -rf /root/* && apt-get remove -y build-essential unzip

ADD nginx.conf /usr/local/nginx/conf/nginx.conf

ENTRYPOINT ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]

最重要的是nginx 的配置文件：
nginx.conf：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
events {
    worker_connections  1024;
    use                epoll;
    multi_accept          on;
}

        location = /50x.html {
            root   html;
        }

    }
}

编译好了，之后就可以启动了。
折腾半天，原来是配置不对，没有启动。

3，查看效果

---

启动之后就可以看效果了。把html 空格去掉了。自动优化呢。

同时使用pagespeed_admin 可以看到很多配置。直观很多。

4，总结

---

pagespeed 非常强大，使用非常简单。直接压缩优化了。
这个只是简单的跑通了，更多nginx 参数可以参考：
