Nginx配置http2

Nginx配置支持Http2.0

配置支持前提：

1. Nginx1.10.0以上版本才支持Http2.0，如果使用的是Tengine，版本需要大于2.2.1，且需要添加--with-http_v2_module模块。
2. Http2.0只支持Https协议的网站，且openssl版本需要高于1.0.2。

一、查看当前Nginx安装了哪些模块

/usr/sbin/nginx -V
nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E'

二、安装，升级

这里以最新版的Tengine为例

> wget http://tengine.taobao.org/download/tengine-2.2.3.tar.gz
> cd tengine-2.2.3
> ./configure --prefix=/usr/share/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module
# 执行make编译
> make
# 如果是首次安装Nginx，执行make install；如果是升级，执行make upgrade
> make upgrade
# 完成后查看已经安装的模块，可以发现已经有http2（--with-http_v2_module）模块了
> nginx -V

三、配置Nginx

Nginx配置http2很简单，只需要在listen的端口后新增http2标识即可，如下

server {
    listen       443 ssl http2;
    server_name  hostname.com;

    ssl_certificate   cert/214547145790616.pem;
    ssl_certificate_key  cert/214547145790616.key;

    location / {
        proxy_pass http://localhost:12345;
    }
}

四、检查http2是否生效
打开chrome控制台，在Name一栏右键把Protocol勾选上
