## 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
> 如果当前版本不支持http2.0 那么请升级nginx版本,升级办法本博客有.
```
#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

修改 大约39-43行:

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

CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libcrypto.a"
CORE_LIBS="$CORE_LIBS $NGX_LIBDL"
```
**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: ; rel=preload; as=style
多个资源推送:
Link: ; rel=preload; as=style, ;
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
```
