@Ritesh

I am using Centos6.6 not Centos 7 . The link which you have given for Centos 7

systemd is not available for with version 6, and version6 is not prepared for systemd. Do not attempt to install systemd on version6…
version 6 - RHEL/Centos6

@Ritesh

Thanks for your reply an information

You won`t install the systemd over initd system and service managers,

If you like systemd consider for upgrading your distro to CentOS 7
