Linux下升级openssl到新版本（如CentOS 7中openssl升级到openssl 1.1.1d）后，其实原nginx并没有真正调用新的openssl 1.1.1d。怎么办呢？需对nginx重新编译，但在编译安装过程中有人就无法编译nginx了，遇到如下问题：[root@centos7 nginx-1.16.1]# make
make -f objs/Makefile
make[1]: 进入目录“/usr/local/src/nginx-1.16.1”
cd /usr/local/openssl
&& if [ -f Makefile ]; then make clean; fi
&& ./config --prefix=/usr/local/openssl/.openssl no-shared no-threads
&& make
&& make install_sw LIBDIR=lib
/bin/sh:行2: ./config: 没有那个文件或目录
make[1]: *** [/usr/local/openssl/.openssl/include/openssl/ssl.h] 错误 127
make[1]: 离开目录“/usr/local/src/nginx-1.16.1”
make: *** [build] 错误 2
怎么办呢？解决办法如下：进入/usr/local/src/nginx-1.16.1/auto/lib/openssl中
#vim conf

也即去掉.openssl/就行。
改后：
#make clean
再依次执行./configure … ;make ;make install即重新编译安装即可。
