OpenNebula - The OpenSource Toolkit for Cloud Computing
DESCRIPTION
OpenNebula is an open-source project aimed at building the industry standard open source cloud computing tool to manage the complexity and heterogeneity of distributed data center infrastructures.
Complete documentation can be found at
http://opennebula.org/documentation:documentation
INSTALLATION
REQUISITES
This machine will act as the OpenNebula server and therefore needs to have installed the following software:
- ruby >= 1.8.5
- sqlite3 >= 3.5.2
- xmlrpc-c >= 1.06
- openssl >= 0.9
- ssh
- 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)
- libxml2-dev
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:
http://opennebula.org/documentation:documentation:compile
If you want to install them manually here are the list of required rubygems:
-
OpenNebula and clients (plus cloud interfaces)
- sqlite3
- json
- sequel
- mysql
- net-ldap
- amazon-ec2
- rack
- sinatra
- thin
- uuidtools
- curb
- nokogiri
-
OpenNebula zones (client and server)
- json
- sequel
- sqlite3
- mysql
- nokogiri
-
Sunstone server
- json
- rack
- sinatra
- thin
- sequel
- nokogiri
OPTIONAL PACKAGES
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
- ruby-dev
- rubygems
- rake
- make
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 nokogiri, to install this gem you will need libxml2 and libxslt libraries and their development versions. The we can install nokogiri library:
$ sudo gem install nokogiri --no-ri --no-rdoc
BUILDING
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
INSTALLATION
-
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
-h prints installer help
