Http2.0已经发布很久了，其优点前篇文章已经介绍过了HTTP2-0原理解析，今天我们来配置Nginx使其支持Http2.0安装前必读：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2.2.1Http2.0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（如果事先没有安装Nginx，请忽略此步骤）> /usr/sbin/nginx -Vnginx version: nginx/1.12.2built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)built with OpenSSL 1.0.2k-fips 26 Jan 2017TLS SNI support enabledconfigure 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’可以看到http2.0模块–with-http_v2_module已经存在了，方便演示就重新执行一遍二、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NginxNginx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勾选上欢迎订阅「K叔区块链」 - 专注于区块链技术学习 博客地址：http://www.jouypub.com简书主页：https://www.jianshu.com/u/756c9c8ae984segmentfault主页：https://segmentfault.com/blog/jouypub腾讯云主页：https://cloud.tencent.com/developer/column/72548
