Do you think we are missing an alternative of OpenNebula or a related project?
OpenNebula is an open-source project delivering a simple but feature-rich and flexible solution to build and manage enterprise clouds and virtualized data centers.
Complete documentation: https://docs.opennebula.org
How to contribute: https://github.com/OpenNebula/one/wiki/How-to-Contribute-to-Development
This machine will act as the OpenNebula server and therefore needs to have installed the following software:
- ruby >= 1.8.7
- sqlite3 >= 3.5.2
- xmlrpc-c >= 1.06
- openssl >= 0.9
- sqlite3-ruby gem
Additionally, to build OpenNebula from source you need:
- Development versions of the sqlite3, xmlrpc-c and openssl packages, if your distribution does not install them with the libraries.
- scons >= 0.97
- g++ >= 4
- flex >= 2.5 (optional, only needed to rebuild the parsers)
- bison >= 2.3 (optional, only needed to rebuild the parsers)
- libvncserver-dev (optional, only needed to build svncterm_server)
Ruby Libraries Requirements
A set of gem requirements are needed to make several components work. We
include a handy script to install them and the requirements. It is located at
share/install_gems/install_gems and you should use it to install the
required gems. You have more information at:
If you want to install them manually here are the list of required rubygems:
OpenNebula and clients (plus cloud interfaces)
These packages are not needed to run or build OpenNebula. They improve the performance of the user-land libraries and tools of OpenNebula, nor the core system. You will probably experiment a more responsive CLI.
First install rubygems and ruby development libraries
Then install the following packages:
ruby xmlparser, some distributions include a binary package for this (libxml-parser-ruby1.8). If it is not available in your distribution install expat libraries with its development files and install xmlparser using gem:
$ sudo gem install xmlparser --no-ri --no-rdoc
Note the extra parameters to gem install. Some versions of xmlparser have problems building the documentation and we can use it without documentation installed.
ruby ox, fast xml parsing library:
$ sudo gem install ox --no-ri --no-rdoc
Compilation is done using scons command:
$ scons [OPTION=VALUE]
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 new_xmlrpc yes if you have an xmlrpc-c version >= 1.31 sunstone yes if you want to build sunstone minified files systemd yes if you want to build systemd support svncterm no if you want to skip building vnc support for LXD drivers
OpenNebula can be installed in two modes: system-wide, or in self-contained directory. In either case, you do not need to run OpenNebula as root. These options can be specified when running the install script:
$ ./install.sh install_options
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 -c only install client utilities: OpenNebula cli, occi and ec2 client files -r remove Opennebula, only useful if -d was not specified, otherwise rm -rf $ONE_LOCATION would do the job -p do not install OpenNebula Sunstone non-minified files -G install only OpenNebula Gate -f install only OpenNebula Flow -h prints installer help
