升级到HTTP/2 | 哈喽哈咯

在看了一位V友的博文过后就心里有点痒，午饭的时候就忍不住动手了，整个过程居然还有点小坎坷。。。

首先是得添加Nginx的源：

1	sudo vim /etc/apt/sources.list

添加以下内容：

1 2	deb http://nginx.org/packages/mainline/ubuntu/ trusty nginx deb-src http://nginx.org/packages/mainline/ubuntu/ trusty nginx

这个跟V友博文里面写的不一样，但是我之前按照他写的来添加源有报404，Debian的源Ubuntu估计还是不能直接拿来用。

过后还要下载添加一个证书：

1	wget http://nginx.org/keys/nginx_signing.key && sudo apt-key add nginx_signing.key

然后更新源并重新安装Nginx

1	sudo apt-get update && sudo apt-get install nginx

这里有可能会报错：

Use 'apt-get autoremove' to remove them.

是跟nginx-common冲突了，所以需要卸载nginx-common

1	sudo apt-get remove nginx-common

然后再安装一遍就OK了。

装好Nginx过后注意要在nginx.conf里面更改用户名，因为Ubuntu源里面的Nginx默认用户是www-data，然后Nginx自己的源里面的默认用户是nginx，如果不改的话瞬间403，印象中之前在本地Archlinux上也碰到过这个问题，当时直接用了服务器上面的Nginx配置文件，然后死命403，我也就奇了怪了，在网上找来找去，各种解决方案都有，就是没人说Nginx用户不一致的问题。

1	user www-data;

然后这个时候Nginx就升级完毕了：

1 2	$ nginx -v nginx version: nginx/1.9.6

接着就可以开启HTTP/2了，直接修改网站的配置文件：

将

1	listen 443;

改成

1	listen 443 ssl http2;

就可以启动HTTP/2了，过后重启一下Nginx，过户打开浏览器的调试页面就可以看到是否已经是HTTP/2了

速度好像是。。。快了一丢丢。。。
