While i'm deploying my rails application through capistrano to my CentOS server all the time i have been receiving this error:
*** ERROR: Phusion Passenger doesn't seem to be running. If you are sure that it is running, then the causes of this problem could be one of:
- You customized the instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument. If so, please set the environment variable PASSENGER_INSTANCE_REGISTRY_DIR to that directory and run this command again.
- The instance directory has been removed by an operating system background service. Please set a different instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument.
On my server i have apache and passenger 5.0.30 Firstly i was looking on others answers here on stack: Link to one of these topics. Unfortunately nothing hasn't helped me. I tried to set the env path and others settings from apache conf as well. Any idea what should i change in order to deploy my rails app? Where is the full path to the first passenger-status in PATH? Does it match passenger_root? Below are my logs:

USERNAME=root

SUDO_USER=userr
SUDO_UID=1001
SUDO_GID=100
PASSENGER_INSTANCE_REGISTRY_DIR=/tmp
For sure i'm making something wrong. Thanks for every advice.
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"
}
