25.5. Prerequisites

Ensure that you do the following before using Red Hat Gluster Storage Object Store.
  • Ensure that the openstack-swift-* and swiftonfile packages have matching version numbers. 
    # rpm -qa | grep swift
openstack-swift-container-1.13.1-6.el7ost.noarch
openstack-swift-object-1.13.1-6.el7ost.noarch
swiftonfile-1.13.1-6.el7rhgs.noarch
openstack-swift-proxy-1.13.1-6.el7ost.noarch
openstack-swift-doc-1.13.1-6.el7ost.noarch
openstack-swift-1.13.1-6.el7ost.noarch
openstack-swift-account-1.13.1-6.el7ost.noarch
  • Ensure that SELinux is in permissive mode. 
    # sestatus 
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   permissive
Mode from config file:          permissive
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Max kernel policy version:      28
    If the Current mode and Mode from config file fields are not set to permissive, run the following commands to set SELinux into permissive mode persistently, and reboot to ensure that the configuration takes effect. 
    # setenforce 1
# reboot
  • Ensure that the gluster-swift services are owned by and run as the root user, not the swift user as in a typical OpenStack installation. 
    # cd /usr/lib/systemd/system
# sed -i s/User=swift/User=root/ openstack-swift-proxy.service openstack-swift-account.service openstack-swift-container.service openstack-swift-object.service openstack-swift-object-expirer.service
  • Start the memcached service: 
    # service memcached start
  • Ensure that the ports for the Object, Container, Account, and Proxy servers are open. Note that the ports used for these servers are configurable. The ports listed in Table 25.1, “Ports required for Red Hat Gluster Storage Object Store” are the default values.
