#打开nginx源文件下的/usr/local/src/nginx-1.17.2/auto/lib/openssl/conf文件：
找到这么一段代码：
CORE_INCS="$CORE_INCS $OPENSSL/.openssl/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/.openssl/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libcrypto.a"
CORE_LIBS="$CORE_LIBS $NGX_LIBDL"
修改成以下代码：
CORE_INCS="$CORE_INCS $OPENSSL/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libcrypto.a"
CORE_LIBS="$CORE_LIBS $NGX_LIBDL"

#上面修改比较麻烦 可以通过sed进行修改：
sed -i 's#CORE_INCS="$CORE_INCS $OPENSSL/.openssl/include"#CORE_INCS="$CORE_INCS $OPENSSL/include"#g'  /usr/local/src/nginx-1.17.2/auto/lib/openssl/conf

sed -i 's#CORE_LIBS="$CORE_LIBS $NGX_LIBDL"#CORE_LIBS="$CORE_LIBS $NGX_LIBDL"#g' /usr/local/src/nginx-1.17.2/auto/lib/openssl/conf

#再次执行：
