Error creating Kibana 6 pid file in /var/run/ directory

I have installed Kibana 6 in Centos 7.4 and I have configured pid file location to /var/run/mypidfile.pid. I want to write in this location because when server is rebooted, I need that Kibana starts automatically.

I have tried changing pid file location to under kibana owned directory. It only works when I start and stop manually the process, but not when the server is rebooted. Whether /var/run/mypidfile.pid location is setted previusly with right Kibana permissions, It is not valid after server has been rebooted.

Journalctl shows this.

I have reviewed audit.log file. There were no messages.

/etc/kibana.yml

pid.file: /var/run/mypidfile.pid

I have tried to resolve it by setting some unit-d file variables.

ExecStartPre=touch /var/run/mypidfile.pid

ExecStartPre=chown kibana /var/run/mypidfile.pid

It did not work. So, I tried with another variable, dropping after-mentioned variables.

PIDFile=/var/run/mypidfile.pid

Are there another manner to do this?
