# OpenNebula



## Description



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: http://opennebula.org/documentation:documentation



How to contribute: http://opennebula.org/community:contribute



## Installation



### Requirements



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
