  • Last updated on: 2017-06-02
  • Authored by: Alex Juarez

This article outlines our Fanatical Support® of software and server configurations for machines (virtual and physical) running a supported Linux operating system.

Operating systems

The following operating systems are supported for both Dedicated and Managed Operations:

  • CentOS 7
  • CentOS 6
  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux 6
  • Ubuntu 16.04 LTS (Xenial Xerus)
  • Ubuntu 14.04 LTS (Trusty Tahr)

The following operating systems are supported only for Managed Operations:

  • Debian 8 (Jessie)
  • Debian 7 (Wheezy)

Note: Rackspace makes every effort to align our support dates for operating systems with the manufacturer’s support dates. If a manufacturer decides to shorten the support life of an operating system, Rackspace might be forced to end support sooner than originally anticipated. For full details on support life, see the Rackspace EOL Terms.

Web servers

The following types of web servers are supported in the indicated areas:

  Installation Configuration Troubleshooting Patching
Apache Yes Yes Yes Yes

Database servers

The following types of database servers are supported in the indicated areas:

  Installation Configuration Troubleshooting Patching
MySQL and MariaDB Yes Yes Yes Yes
Percona Yes Yes Yes Yes

Note: Linux OS administrators handle basic database support topics. Advanced topics might require DBA support assistance. PostgreSQL, MongoDB, and Oracle are not supported by Linux OS administrators. The Rackspace DBA team supports Oracle and MySQL. PostgreSQL requests can be considered on a case-by-case basis. The Rackspace DBA team is available for support consultation on database issues; fees might apply. For more information visit our DBA Services page.

Note: Rackspace will install and support the official Oracle MySQL, MariaDB and Percona MySQL software from the vendor’s repositories.

File servers

The following file servers are supported in the indicated areas:

  Installation Configuration Troubleshooting Patching
vsftpd Yes Yes Yes Yes
NFS Yes Yes Yes Yes
CIFS (client) Yes Yes Yes Yes

Note: Although lsyncd is not strictly a file server technology, we commonly use it at Rackspace in place of NFS services on cloud servers. Bidirectional data transfer with lsyncd is not supported.

Mail servers

The following mail servers are supported in the indicated areas:

  Installation Configuration Troubleshooting Patching
Postfix Yes Yes Yes Yes
Dovecot Yes Yes Yes Yes

Note: By their nature, cloud servers have ephemeral IP addresses which most email providers blacklist. Emails sent from a cloud server must go through a third-party application such as Mailgun. Rackspace does not support mail hosting services on cloud servers and recomends Rackspace Email Hosting for cloud environments.
