Install Basic Operating System
The latest version of Debian GNU/Linux 7 (7.9 as of this writing) should be installed on each host used by a HUBzero installation.
HUBzero has packaging support for amd64 (64bit) Intel architectures. i386 (32bit) packaging is possible but was not produced for this release due to lack of demand. Debian 6 LTS support might be possible with third-party upgrade packages for PHP and MySQL and Debian 8 support will be available as soon as a reliable OpenVZ kernel installation process is available.
Installing Debian GNU/Linux using a small bootable CD (see iso-cd subdirectory) is the simplest method.
When the installation is complete your system will reboot into a Debian GNU/Linux system.
Don't forget to remove your installation media and/or change your server's boot media order if you changed them prior to installation.
The precise configuration (such as disk configuration, networking, etc) is dependent on how the hub is to be used and what hardware is being used. These instructions outline the simplest "hub in a box" configuration but may not be suitable for larger sites. It is expected that the hub will be managed by an experienced Linux administrator who can help scale your site to the capacity required.
Throughout this documentation you will see specific instructions for running commands, with part of the text highlighted. The highlighted text should be modified to your local configuration choices. (e.g. replace "example.com" with the fully qualified hostname of your machine).
Optional. If you didn't specify the fully qualified domain name when running setup you will need to set it here.
HUBzero expects the `hostname` command to return the fully qualified hostname for the system.
# hostname example.comTo make the change permanent you must also edit the file /etc/hostname, this be done simply with:
# echo "example.com" > /etc/hostname
Now edit /etc/hosts by making sure that a line exists that looks like
127.0.1.1 example.com example
Any other lines with "127.0.1.1" should be removed.
Delete local users
HUBzero reserves all user ids from 1000 up for hub accounts. As part of the HUBzero middleware every account must map to a corresponding system account. Therefore when starting up a hub it is required to remove all accounts that have user ids 1000 or greater. On a new installation there is typically one such account that is created when you set up the hub, and this account can be removed as follows:
# rm -fr /home/username # deluser username
If you require additional system accounts, they can be numbered between 500-999 without interfering with hub operations.
Optional. If you didn't configure networking during installation you will need to do so now.
For help with networking setup try this link.Setting up your IP address.
The IP addresses associated with any network cards you might have are read from the file /etc/network/interfaces. This file has documentation you can read with:
# man interfaces
A sample entry for a machine with a static address would look something like this:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.90 gateway 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255
Here we've setup the IP addresss, the default gateway, and the netmask.
For a machine running DHCP the setup would look much simpler:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface - use DHCP to find our address auto eth0 iface eth0 inet dhcp
(If you're using a DHCP based setup you must have a DHCP client package installed - usually one of pump or dhcp-client.)
If you make changes to this file you can cause them to take effect by running:
# /etc/init.d/networking restart
Setting up DNS
Use whatever nameserver and other options as recommended by your ISP. If you used DHCP to set up networking it is likely this has already been set.
When it comes to DNS setup Debian doesn't differ from other distributions. To cause your machine to consult with a particular server for name lookups you simply add their addresses to /etc/resolv.conf.
For example a machine which should perform lookups from the DNS server at IP address 192.168.1.10 would have a resolv.conf file looking like this:
Configure Advanced Package Tool
Now configure the location of the HUBzero package repository by adding the following line to /etc/apt/sources.list
deb http://packages.hubzero.org/deb ellie-deb7 main deb http://download.openvz.org/debian wheezy main
You will need to get and install the hubzero archive key to be able to verify packages from the hubzero archive:
apt-key adv --keyserver pgp.mit.edu --recv-keys 143C99EF
You will aso need the OpenVZ archive key to be able to verify packages from the OpenVZ archive:
wget http://ftp.openvz.org/debian/archive.key -q -O - | apt-key add -
With the above configure update the local package database with information about the packages now available through these new repositories:
# apt-get update
