阿里云openssl升级,实现nginx主动推送，nginx主动推送能够有效减少不必要的报文传输,减少用户请求次数,以达到更快访问速度

现有版本检查

[root@node3 ~]# openssl version               #这个版本是无法支持http2.0主动推送功能.需要升级为2019版本.

OpenSSL 1.0.2k-fips 26 Jan 2017

安装一个nginx

 #安装一个nginx 也可以自定义安装.  yum安装的nginx默认路径: /etc/nginx
 yum install -y nginx
 yum install -y pcre pcre-devel openssl openssl-devel gd-devel  zlib-devel

 #检查编译参数 , 我们需要后面重新编译来添加 openssl

然后输入  make  进行预编译

make

make install

编译出错信息和解决办法:

compilation terminated.

make[1]: Leaving directory `/server/tools/openssl-1.1.1d'
make: *** [all] Error 2

缺少openssl开发依赖包:
yum install openssl-devel -y

安装完成后再次进行 make预编译

出现以下信息,则安装成功.:

创建新的openssl软连接:

mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/include/openssl /usr/include/openssl.old
ln -s /usr/local/bin/openssl /usr/bin/openssl
ln -s /usr/local/include/openssl/ /usr/include/openssl

修改 大约39-43行:

CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libssl.a"

到这里openssl版本升级完成

openssl添加到nginx

1. yum安装一个nginx, 检查nginx openssl版本

2. 将新版本openssl加入到nginx中

现有nginx版本检查

配置nginx主动推送

nginx主动推送配置
主动推送,可以减少用户请求的报文,缩短响应时间,提高用户访问速度.

nginx配置中添加http2支持:
server {
...
listen 443 ssl http2 default_server;
...
}

主动推送方法1. :
http2_push_preload on;
Link: </styles.css>; rel=preload; as=style

多个资源推送:
Link: </styles.css>; rel=preload; as=style, </example.png>;
rel=preload; as=image

主动推送方式2. :
http2_push /mi.txt;
http2_push /style.css;

nghttp测试:
nghttp工具默认并没有安装,需要使用 yum install -y nghttp 来安装该测试工具.

nghttp -ns https://wh02.com

结果图:

注意

[当编译安装openssl 没有指定路径后,在当前服务器重装nignx,需要指定openssl路径,如果修改成下面的配置,就可以不用指定openssl路径 [默认路径--with-openssl=/usr/local] ]
nginx-1.16.1/auto/lib/openssl/conf 大约139行的位置,修改完成后再做编译.
