Problem solved, there was a configuration file for this app that specifically referenced /usr/bin/php, ie the default version php54. I am now able to run the script in a terminal window but creating a systemd unit still does not work and still references the default version php54. Googling I found this that suggests serviced works differently with respect to eg php installed from Software Collections: https://access.redhat.com/solutions/527703 Is anyone familiar with this? _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
