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 en_US.utf8
If no locale is installed, you can generate it with the following command:
BlueMind requires a blank, dedicated server or virtual machine.
BlueMind doesn't support LXC technology, you should use KVM instead.
BlueMind requires a 64-bit version of supported distributions (for Ubuntu, make sure you have the Server version):
Debian 7 Wheezy
To continue being able to update BlueMind in this distribution, you must update repository addresses in the file
*available for BlueMind 3.5.9 and above
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:
Otherwise, a warning may come up during earlier version updates. Please note that this will not disrupt updates.
To ensure to that the installation script is able to run commands with elevated privileges (sudo), the
requiretty directive must not be enabled in the configuration file
/etc/sudoers. If it is present, you must remove it or keep it as a comment.
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 -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
IP_SERVER mail.blue-mind.net mail
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.
