Available Memory

BlueMind's default configuration requires at least 6Gb.


The en_US.UTF-8 must be installed and generated (even if the system is configured to use another locale).

To check that it is installed correctly, use the following command line:

$ locale -a|grep en_US

If locale is not installed, you can generate it with the following command :

# local-gen en_US.utf8

Linux distribution

BlueMind requires a blank, dedicated server or virtual machine.

BlueMind requires a 64-bit version of supported distributions (for Ubuntu, make sure you have the Server version):

  • Ubuntu 14.04 LTS Server (Trusty Tahr)
  • Ubuntu 16.04 LTS Server (Xenial Xerus)
  • Ubuntu 18.04 LTS Server (Bionic Beaver)*
  • RedHat 6
  • RedHat 7
  • Debian 7 Wheezy
  • Debian 8 Jessie
  • Debian 9 Stretch

*available in BlueMind 3.5.9 and higher

Repository signature

Repositories are now signed for all supported Ubuntu/Debian distribution – this is a requisite for Ubuntu 18.04 and Debian 9.

You may, if you need or want to, manually import the key on all our supported distributions using the following command:

curl | apt-key add -

Otherwise, a warning may come up during earlier version updates. Note that this will not disrupt updates.

Network & DNS

IP address

The server must have a static IP, system defined or supplied by a DHCP server.


The BlueMind server hostname must be configured correctly, and the server name must be resolvable by name from another machine.

Specifically, BlueMind expects the following results to the hostname command:

$ hostname

  must return the short system name, e.g. here: mail 

$ hostname -f

 must return the fully qualified system name (FQDN), e.g. here:

The hostname also has to be properly set in the server's /etc/hosts file:


Network cards

If your server has several network cards, the first one (eth0) must bear the BlueMind server's external IP address.


The guidelines below are not required but recommended to make your server's maintenance more straightforward.
