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。

USER root

ENV Nginx_VERSION 1.9.9

RUN apt-get update && apt-get install -y build-essential zlib1g-dev libssl-dev libpcre3 libpcre3-dev unzip uuid-dev curl && \
    cd /root && curl -O http://Nginx.org/download/Nginx-1.9.9.tar.gz && \

    curl -O https://dl.google.com/dl/page-speed/psol/1.13.35.2-x64.tar.gz && tar -xzvf 1.13.35.2-x64.tar.gz

RUN cd /root/Nginx-1.9.9 && ./configure --add-module=/root/incubator-pagespeed-ngx-latest-stable --with-http_mp4_module \
    --with-http_sub_module  --with-http_stub_status_module  --with-http_v2_module && \

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：
