Installation of the software |
| 48 |
============================ |
| 49 |
|
| 50 |
To install, simply do ``./configure --localstatedir=/var --sysconfdir=/etc && \ |
| 51 |
make && make install`` |
| 52 |
|
| 53 |
This will install the software under /usr/local. You then need to copy |
| 54 |
ganeti.init to /etc/init.d/ganeti and integrate it into your boot sequence |
| 55 |
(``chkconfig``, ``update-rc.d``, etc.). |
| 56 |
|
| 57 |
|
| 58 |
Cluster initialisation |
| 59 |
====================== |
| 60 |
|
| 61 |
Before initialising the cluster, on each node you need to create the following |
| 62 |
directories: |
| 63 |
|
| 64 |
- /etc/ganeti |
| 65 |
- /srv/ganeti, /srv/ganeti/os, /srv/ganeti/export |
| 66 |
|
| 67 |
After this, use ``gnt-cluster init``. |
