systemctl edit [name of service].service
That I believe will take care of both creating the directory and file structure and take care of daemon-reload once editing is complete.

A small correction;
The “su – apache -c ‘ulimit -aHS’ -s ‘/bin/bash'” responds to the user not the process.

To find the limits for the process, point to the PID ogf the wrapper:
e.g. for haproxy
pidof haproxy-systemd-wrapper | awk ‘{print “/proc/”$1″/limits”}’ | xargs cat | grep -i open

You can look up via man systemd.exec

If you prefer online version: https://www.freedesktop.org/software/systemd/man/systemd.exec.html

What is the corresponding parameter for it like LimitNOFILE
Can you point to the relevant link

You can type 

su - apache -c 'ulimit -aHS' -s '/bin/bash'

for apache or any other user that you want to check for. You can check here for man of ulimit function: http://ss64.com/bash/ulimit.html
