Please note that a more detailed installation procedure is described in the install. A glossary of terms can be found in the glossary.
Before installing, please verify that you have the following programs:
- Xen Hypervisor, version 3.0 or above, if running on Xen
- KVM Hypervisor, version 72 or above, if running on KVM. In order to use advanced features, such as live migration, virtio, etc, an even newer version is recommended (qemu-kvm versions 0.11.X or above have shown good behavior).
- DRBD, kernel module and userspace utils, version 8.0.7 or above
- LVM2
- OpenSSH
- bridge utilities
- iproute2
- arping (part of iputils)
- ndisc6 (if using IPv6)
- Python, version 2.4 or above, not 3.0
- Python OpenSSL bindings
- simplejson Python module
- pyparsing Python module
- pyinotify Python module
- PycURL Python module
- ctypes Python module, if running on python 2.4 (optional, used for node daemon memory locking)
- socat
- Paramiko, if you want automated SSH setup; optional otherwise but manual setup of the nodes required
These programs are supplied as part of most Linux distributions, so usually they can be installed via the standard package manager. Also many of them will already be installed on a standard machine. On Debian/Ubuntu, you can use this command line to install all required packages, except for DRBD and Xen:
$ apt-get install lvm2 ssh bridge-utils iproute iputils-arping \
ndisc6 python python-pyopenssl openssl \
python-pyparsing python-simplejson \
python-pyinotify python-pycurl socatIf you want to build from source, please see doc/devnotes.rst for more dependencies.
To install, simply run the following command:
./configure --localstatedir=/var --sysconfdir=/etc && \
make && \
make installThis will install the software under /usr/local. You then need to copy doc/examples/ganeti.initd to /etc/init.d/ganeti and integrate it into your boot sequence (chkconfig, update-rc.d, etc.).
Before initialising the cluster, on each node you need to create the following directories:
/etc/ganeti/var/lib/ganeti/var/log/ganeti/srv/ganeti/srv/ganeti/os/srv/ganeti/export
After this, use gnt-cluster init.
