While i\'m deploying my rails application through capistrano to my CentOS server all the time i have been receiving this error:

*** ERROR: Phusion Pas

Answer 1

The problem seems to be systemd private temp feature, you can disable that for httpd:

mkdir /etc/systemd/system/httpd.service.d
echo "[Service]" >  /etc/systemd/system/httpd.service.d/nopt.conf
echo "PrivateTmp=false" >> /etc/systemd/system/httpd.service.d/nopt.conf
systemctl daemon-reload
systemctl restart httpd

Passenger 5.0 no longer use /tmp for status information so it should work out of box even on private temps.

Finally i resolved my issue. I have done two things.

Firstly i created new temp folder in my home directory. Then inside Apache config file i added

PassengerInstanceRegistryDir /home/userr/instancetemp

Then i pushed this to my env path with

echo 'PASSENGER_INSTANCE_REGISTRY_DIR=/home/userr/instancetemp' >> ~/.bash_profile

I think this is enough but i added also this path to my capistrano config

set :default_env, { 
  "PASSENGER_INSTANCE_REGISTRY_DIR" => "/home/userr/instancetemp"
}
