二、参考安装文档使用SSL加速卡

2.1 安装QAT软件

（1）百度搜索加速卡型号，获取QAT驱动程序
（2）安装QAT驱动程序

export ICP_ROOT=/opt/QAT
mkdir /opt/QAT
cd /opt/QAT
wget https://downloadmirror.intel.com/30178/eng/QAT1.7.L.4.13.0-00009.tar.gz  # 第一步官方的驱动程序
tar xf QAT1.7.L.4.13.0-00009.tar.gz
./configure
make -j 40
make install
service qat_service status
cpa_sample_code runTests=2    # 测试QAT驱动程序是否安装成功

2.2 安装openssl

git clone https://github.com/openssl/openssl.git
cd openssl/
git checkout OpenSSL_1_1_1    # 我使用最新版本，在后边编译其他qat_engine会报错，应该是QAT_engine还不支持最新版
./config --prefix=/usr/local/ssl -Wl,-rpath,/usr/local/ssl/lib
make -j 40
make install

2.3 安装QAT_engine

git clone https://github.com/intel/QAT_Engine.git
cd QAT_Engine/qat_contig_mem
make    # 我这里会报错error: dereferencing pointer to incomplete type ‘struct task_struct’，参考:http://www.voidcn.com/article/p-pwrzhtun-em.html 解决
vim qat_contig_mem.c
#include <linux/sched.h>   # 添加这条命令，我是在报错行前一行添加的。
make load
make test
……
Hello world!   # 返回信息
……

cd ..
./autogen.sh
./configure --with-qat_hw-dir=/opt/QAT --with-openssl_install_dir=/usr/local/ssl

2.4 安装QATzip

git clone https://github.com/intel/QATzip.git
cd QATzip/
./configure --with-ICP_ROOT=$ICP_ROOT
make clean
make all install
service qat_service restart

2.5 安装nginx + qat模块

git clone https://github.com/intel/asynch_mode_nginx.git
cd asynch_mode_nginx/
./configure --prefix=/usr/local/nginx --conf-path=/etc/nginx/nginx.conf --without-http_rewrite_module --with-http_ssl_module --with-http_stub_status_module --with-http_v2_module --with-stream --with-stream_ssl_module --add-dynamic-module=modules/nginx_qatzip_module --add-dynamic-module=modules/nginx_qat_module/ --with-cc-opt="-DNGX_SECURE_MEM -I$OPENSSL_LIB/include -I$QZ_ROOT/include -I$ICP_ROOT/quickassist/include -I$ICP_ROOT/quickassist/include/dc -Wno-error=deprecated-declarations" --with-ld-opt="-Wl,-rpath=$OPENSSL_LIB/lib -L$OPENSSL_LIB/lib -L$QZ_ROOT/src -lqatzip -lz"

以上服务都可以参考github或官方加速卡介绍安装，由于版本原因，后边可能和我版本不一致等，请参考官网安装. 包括在./configure make autogen时候都会需要一些依赖包，参考报错信息百度即可.

2.6 nginx配置

cp /root/QAT_Engine/qat/config/dh895xcc/multi_process_optimized/dh895xcc_dev0.conf  /etc   # 复制一份配置文件替换老的QAT驱动
service qat_service restart

# nginx 配置文件

    worker_connections  102400;
    use epoll;
    accept_mutex off;
}

        use_engine qatengine;

        qat_engine {

                qat_notify_mode poll;
                qat_poll_mode heuristic;
                qat_sw_fallback on;
        }
}
