Installation through RPMs recommended It looks like you are on a Red Hat or CentOS operating system, with SELinux enabled. SELinux is a security mechanism for which special <%= SHORT_PROGRAM_NAME %>-specific configuration is required. We supply this configuration as part of our <%= SHORT_PROGRAM_NAME %> RPMs. However, <%= SHORT_PROGRAM_NAME %> is currently installed through <%= PhusionPassenger.packaging_method_description %> and does not include any SELinux configuration. Therefore, we recommend that you: 1. Uninstall your current <%= SHORT_PROGRAM_NAME %> install. 2. Reinstall <%= SHORT_PROGRAM_NAME %> through the RPMs that we provide: https://www.phusionpassenger.com/library/install/apache/yum_repo/ What would you like to do?
