显示为1.0版本

编译安装Python3.10时需要openssl1.1.1，所以这里手动删除openssl1.0
yum remove openssl

下载openssl1.1.1源码压缩包：
https://www.openssl.org/source/old/1.1.1/

解压并进入openssl1.1.1路径下:
./config --prefix=/usr/local/openssl
make -j 2
make install

ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl

vim /etc/ld.so.conf
在文件末尾添加一行代码：
/usr/local/openssl/lib

使配置生效：
ldconfig -v

然后在任意路径下输入命令：
openssl version
可以看到版本为openssl 1.1.1
