Configure Nginx with HTTP/2 Support

刚发布不久的 Nginx 1.9.5 正式支持HTTP/2，于是就来折腾一番吧。由于 HTTP/2 是基于 https，因此必须先配置 Nginx 支持 https。文中所有操作都在自己本地机器上进行测试，采用的是 openssl 生成自签名证书。

创建 Key：

1	$ openssl genrsa -des3 -out test.key 1024

创建签名请求：
1
$ openssl req -new -subj "/C=US/ST=Mars/L=iTranswarp/O=iTranswarp/OU=iTranswrap/CN=test" -key test.key -out test.csr
在实际部署时，必须将 CN 字段中的 test 换成域名，否则无法通过浏览器验证。

将 Key 的口令移除：

1 2	$ mv test.key test.origin.key $ openssl rsa -in test.origin.key -out test.key

用Key签名证书:

1	$ openssl x509 -req -days 3650 -in test.csr -signkey test.key -out test.crt

配置 Nginx

重定向所有的流量到 SSL/TLS

server {
    listen 80;
    location / {
            return 301 https://$host$request_uri;
    }
}

启用 HTTP/2

server {
    listen              443 ssl http2 default_server;
    server_name         localhost;
    keeplive_timeout    70;

    ssl_certificate     /path/to/test.crt;
    ssl_certificate_key /path/to/test.key;
    ssl_session_cache   shared:SSL:10m;
    ssl_session_timeout 10m;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA';
    ssl_prefer_server_ciphers on;
}

重新加载配置文件

1 2	$ sudo nginx -t # 检验配置文件是否有错误 $ sudo nginx -s reload
