Installation Guide 2.0
Do not forget to check the Platform Notes for a list of specific software requirements to build OpenNebula.
Follow these simple steps to install the OpenNebula software:
- Download and untar the OpenNebula tarball.
- Change to the created folder and run scons to compile OpenNebula<xterm>
$ scons [OPTION=VALUE] </xterm> the argument expression [OPTIONAL] is used to set non-default values for :
| OPTION | VALUE |
|---|---|
| sqlite_db | path-to-sqlite-install |
| sqlite | no if you don't want to build sqlite support |
| mysql | yes if you want to build mysql support |
| xmlrpc | path-to-xmlrpc-install |
| parsers | yes if you want to rebuild flex/bison files |
- OpenNebula can be installed in two modes:
system-wide, or inself-containeddirectory. In either case, you do not need to run OpenNebula as root. These options can be specified when running the install script:<xterm>
./install.sh <install_options> </xterm> where <install_options> can be one or more of:
| OPTION | VALUE |
|---|---|
| -u | user that will run OpenNebula, defaults to user executing install.sh |
| -g | group of the user that will run OpenNebula, defaults to user executing install.sh |
| -k | keep current configuration files, useful when upgrading |
| -d | target installation directory. If defined, it will specified the path for the self-contained install. If not defined, the installation will be performed system wide |
| -r | remove Opennebula, only useful if -d was not specified, otherwise rm -rf $ONE_LOCATION would do the job |
| -h | prints installer help |
We will do a self-contained installation. As oneadmin user:
<xterm> ~$ wget <opennebula tar gz> ~$ tar xzf <opennebula tar gz> ~$ cd one-2.0 ~/one-2.0$ scons -j2 [ lots of compiling information ] scons: done building targets. ~/one-2.0$ ./install.sh -d /srv/cloud/one </xterm>
Now you need to configure OpenNebula to adjust it to your particular cluster.
Verifying the Installation
Depending on the installation mode (defined by the presence or absence of the -d option in the installation script), there are two possibilities with respect to the layout of the OpenNebula files.
Self contained
Once the OpenNebula software is installed specifying a directory with the -d option, the next tree should be found under $ONE_LOCATION:
System wide
Once the OpenNebula software is installed without specifying a directory with the -d option, the next tree reflects the files installed:
