If the old version is still displayed or installed before, please make a copy of openssl bin file

LinuxHelp:/mnt/openssl-1.0.2t # mv /usr/bin/openssl   /root/

Create soft link for newly installed openssl under bin directory

LinuxHelp:/mnt/openssl-1.0.2t # ln -s /usr/local/ssl/bin/openssl    /usr/bin/openssl

To check the installed version of openssl

LinuxHelp:/mnt/openssl-1.0.2t # openssl version
OpenSSL 1.0.2t  10 Sep 2019

with this, Installation and use of openssl comes to end
