System

Available Memory

BlueMind's default configuration requires at least 6Gb.

Locales

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
en_US.utf8

# local-gen en_US.utf8

Linux distribution

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 7 Wheezy is no longer supported by Debian

  To continue being able to update BlueMind in this distribution, you must update repository addresses in the file /etc/apt/sources.list:

  deb http://archive.debian.org/debian/ wheezy main
  deb http://archive.debian.org/debian/ wheezy-backports main

• Debian 8 Jessie
• Debian 9 Stretch*

*available for BlueMind 3.5.9 and above

curl https://pkg.bluemind.net/bluemind-deb.asc | apt-key add -

add-apt-repository universe
apt update

System configuration

To ensure that the installation script is able to run commands with elevated privileges (sudo), the requiretty directive must not be enabled in the /etc/sudoers configuration file. If it is present, you must remove it or keep it as a comment.

Network & DNS

IP address

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

Hostname

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 -s
mail

  must return the short system name, e.g. in this example mail 

$ hostname -f
mail.blue-mind.net

 must return the fully qualified system name (FQDN), e.g. in this example mail.blue-mind.net

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

IP_SERVER mail.blue-mind.net mail

Network cards

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

Partitioning

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