Tengine开启http2传输协议

1.  http2的优势
   

2.  准备工作
        1.      需要重新编译openssl1.0.2以上版本
        2.      编译完成openssl后，需要重新使用openssl的库文件重新编译Tengine
   

3.  操作过程
        1.      安装openssl-1.0.2t
                    cd /usr/local/src
                    wget https://www.openssl.org/source/openssl-1.0.2t.tar.gz
                    tar -zxvf openssl-1.0.2t.tar.gz
                    cd openssl-1.0.2t
                    ./config shared zlib
                    make && make install
                    mv /usr/bin/openssl /usr/bin/openssl.old
                    mv /usr/include/openssl /usr/include/openssl.old  
                    ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
                    ln -s /usr/local/ssl/include/openssl /usr/include/openssl  
                    echo "/usr/local/ssl/lib" >> /etc/ld.so.conf
                    ldconfig -p
                    openssl version
        2.      安装tengine
                    ./configure --prefix=/usr/local/nginx --user=www --group=www --with-poll_module --with-pcre --with-http_realip_module --with-http_dav_module --with-http_gzip_static_module --with-http_degradation_module --with-http_addition_module --with-http_image_filter_module --with-http_sub_module --with-http_flv_module --with-http_slice_module --with-http_mp4_module --with-http_random_index_module --with-http_secure_link_module --add-module=/usr/local/nginx/modules/nginx-upsync-module --with-http_v2_module --with-http_secure_link_module --with-openssl=/usr/local/ssl
                    make
                    make install      如果是已经安装过tengine，不需要执行make install
                    cp -af objs/nginx /usr/local/nginx/sbin/
                    cp -af objs/dso_tool /usr/local/nginx/sbin/
                    ./nginx -s stop
                    ./nginx
        3.      配置nginx的server
                    server {
                      listen       443 ssl http2;      加入http2
                    }
        4.      浏览器访问页面,f12,出现h2字样
