in the last lines we see remove systemd and yum

Error: Trying to remove "yum", which is protected

how we can force yum remove in order to remove openssl-libs rpm?

Answer

I formally advice you to not delete openssl version provided with the os core, this will break as you seen your package manager “yum” and “systemd” that depends mostly on it.
Instead i would recommend to :

  • Upgrade the system to RHEL6 using yum

Or

  • Install new openssl OS independent package, then your system packages and application will be based and this featured one :

    mkdir ~/src/

    cd ~/src/

    wget https://www.openssl.org/source/openssl-1.0.2a.tar.gz

    tar -zxvf openssl-*.tar.gz

    cd openssl-*

    ./config -fpic shared && make && make install

    echo "/usr/local/ssl/lib" >> /etc/ld.so.conf

    ldconfig

Now check your openssl version :

openssl version
