3. Build Eucalyptus
===================
First, make sure JAVA_HOME and EUCALYPTUS are defined. For example,

For instance, on Ubuntu,

export JAVA_HOME="/usr/lib/jvm/java-1.7.0-openjdk-amd64/"
export JAVA="$JAVA_HOME/jre/bin/java"
export EUCALYPTUS="/"

On RHEL or CentOS,

export JAVA_HOME="/usr/lib/jvm/jre-1.7.0/"
export JAVA="$JAVA_HOME/bin/java"
export EUCALYPTUS="/"

Then run the "configure" script.

For instance, on Ubuntu,

./configure --with-axis2c=/usr/lib/axis2 \
--with-axis2c-services=/usr/lib/axis2/services --prefix=$EUCALYPTUS \
--with-apache2-module-dir=/usr/lib/apache2/modules \
--with-db-home=/usr/lib/postgresql/9.1 \
--with-axis2=/opt/axis2-1.4

On RHEL or CentOS,

./configure '--with-axis2=/usr/share/axis2-*' \
--with-axis2c=/usr/lib64/axis2c --prefix=$EUCALYPTUS \
--with-apache2-module-dir=/usr/lib64/httpd/modules \
--with-db-home=/usr/pgsql-9.1 \
--with-wsdl2c-sh=/opt/euca-WSDL2C.sh

make clean ; make ; make install

4. Deploy Eucalyptus
====================
At this point, if you plan to use Eucalyptus on more than one system, you're
ready to push the software out to the other systems (although not all software
components are required on all systems, it is simpler to just mirror everything
and selectively enable components via start-up scripts). If you installed
Eucalyptus in its own directory, you can just sync the entire package to all of
the hosts listed above using whatever mechanism you typically use to push
changes to systems (rsync, for instance).

rsync -a $EUCALYPTUS/ root@{host-2}:$EUCALYPTUS/
rsync -a $EUCALYPTUS/ root@{host-3}:$EUCALYPTUS/
...

On installations without a root user that can log in, such as Ubuntu, it may be
easier to pull the software from each system one at a time:

host-2# rsync -a {user}@{host-1}:$EUCALYPTUS/ $EUCALYPTUS/
host-3# rsync -a {user}@{host-1}:$EUCALYPTUS/ $EUCALYPTUS/

NOTE: For the system running the NC you will also need to install the policykit
configuration. Copy the file './tools/eucalyptus-nc-libvirt.pkla' to the NC and
put it under the directory '/var/lib/polkit-1/localauthority/10-vendor.d/'

5. Configure and Use Eucalyptus
===============================

At this point forward, please follow instructions from the "Configuring
Eucalyptus" section of the Installation Guide.

You can access Eucalyptus Documentation here (under construction):

1. Prerequisites
================
What follows is a comprehensive list of dependencies that must be satisfied
before building Eucalyptus or running it. While we provide
distribution-specific installation instructions that help satisfy these
dependencies, this list should be useful if you are installing or building
Eucalyptus on an unsupported distribution. NOTE - If you are upgrading from a
Eucalyptus 1.6.2 or older installation, please consult the Upgrade
Documentation for instructions that will explain how to preserve user account
information, images, volumes and snapshots.

Prerequisites for compiling from source:

    * C compilers
    * Java Developer Kit (SDK) version 1.6 or above
    * Apache ant 1.6.5 or above
    * libc development files
    * pthreads development files
    * libvirt development files
    * Axis2C and rampart development files (included with Eucalyptus)
    * Curl development files
    * openssl development files
    * Optional: zlib development files

Prerequisites for running Eucalyptus:

There are a few different Eucalyptus components that run on either the
'front-end or 'node'. There are different run-time dependencies for 'front-end'
and 'node' components. One physical machine can play the role of the front-end
and the node.

Front-end run-time dependencies:

    * Java 6 is needed by the Eucalyptus components running on the front end.
      Note that GNU Compiler for Java (gcj), included by default with some Linux
      distributions, is not sufficient. Make sure that your JAVA_HOME environment
      variable is set to the location of your JDK.

    * Perl is used by helper scripts
    
    * The head node must run a server on port 25 that can deliver or relay email
      messages to cloud users' email addresses. This can be Sendmail, Exim, or
      postfix, or even something simpler, given that this server does not have to
      be able to receive incoming mail. Many Linux distributions satisfy this
      requirement out of the box. To test whether you have a properly functioning
      mail relay for localhost, try to send email to yourself from the terminal
      using "mail".

    * Dependencies for network support differ depending on the mode used (see
      Eucalyptus Network Configuration for details). For full functionality
      satisfy all of them:
          o For all modes:
                + iproute and iptables packages (ip and iptables commands must work)
          o For all modes except SYSTEM:
                + DHCP Server compatible with ISC DHCP Daemon version 3.0.X (dhcp3-server)
          o For MANAGED and MANAGED-NOVLAN modes:
                + bridge-utils package (brctl command must work)
                + vtun package, for multi-cluster configurations
          o Additionally, for MANAGED mode:
                + vlan package (vconfig command must work)
    * For persistent dynamic block storage (aka EBS) to work, the front end will
      need to have the following software packages installed:
          o lvm2 package (e.g., command lvm should work)
          o aoetools package. The aoe module needs to be loaded on the front end
            as well as all nodes (modprobe aoe). If your kernel does not have
            ATA-over-Ethernet support, you will have to add that.
          o vblade package

Node run-time dependencies:

    * Perl scripts are invoked by the Node Controller
    * Two hypervisors are supported:
         1. Xen (version >= 3.0.x)
                o Furthermore, xen-utils package is needed (xm command must work)
         2. KVM
    * Dependencies for network support differ depending on the mode used (see
      Eucalyptus Network configuration for details). For full functionality
      satisfy all of them:
          o For all modes:
                + iproute and iptables packages (ip and iptables commands must work)
          o For MANAGED and MANAGED-NOVLAN modes:
                + bridge-utils package (brctl command must work)
          o Additionally, for MANAGED mode:
                + vlan package (vconfig command must work)
    * libvirt package (potentially with libvirtd, depending on hypervisor configuration)

All Eucalyptus components:

    * You must be root to install and start Eucalyptus components (by default
      they will run under a different user after start). This document assumes
      that all commands will be executed as root.

Attention CentOS users:The version of OpenJDK that is bundled with CentOS-5
cannot compile the version of GWT that comes with Eucalyptus as a dependency.
You will need to install JDK 1.6.0 "manually". We use Sun's JDK, which can be
found at http://java.sun.com/javase/downloads/index.jsp. Be sure to set your
JAVA_HOME and PATH properly before running the Eucalyptus 'configure' script.

Distribution-specific examples:

What follows is a superset of all packages necessary for building and running
Eucalyptus on each supported distribution:

    * For Opensuse 11.2, download and install RPMs the appropriate OpenSUSE RPM
      dependency package from the Eucalyptus website, then run the following
      command to install all required dependency packages:

zypper -n install curl bzr python-paramiko make gcc ant apache-ivy apache2 \
    apache2-prefork apache2-devel java-1_7_0-openjdk java-1_7_0-openjdk-devel \
    libvirt-devel libcurl-devel vlan dhcp-server bridge-utils ant-contrib \
    ant-nodeps openssl libvirt libcurl-devel vlan apache2 perl-Crypt-OpenSSL-Random \
    perl-Crypt-OpenSSL-RSA libfuse2 tgt swig

    * For Ubuntu 10.04, run the following command to install all required dependency packages:

apt-get install bzr gcc make apache2-threaded-dev ant openjdk-7-jdk libvirt-dev \
    libcurl4-openssl-dev dhcp3-server vblade apache2 unzip curl vlan bridge-utils \
    libvirt-bin kvm vtun

    * For CentOS 5 and Fedora 12, download and install RPMs the appropriate
      CentOS or Fedora RPM dependency package from the Eucalyptus website, then
      run the following command to install all required dependency packages:

yum install -y java-1.7.0-openjdk-devel ant ant-nodeps apache-ivy libvirt-devel curl-devel httpd httpd-devel apr-devel openssl-devel dhcp libxml2 libxml2-devel gnutls gnutls-devel xen-devel libgcrypt-devel zlib-devel perl-Convert-ASN1 perl-Crypt-OpenSSL-RSA perl-Crypt-OpenSSL-Random chkfontpath scsi-target-utils fuse-libs swig gcc

    * For Debian, run the following command to install all required dependency packages:

apt-get install gcc make apache2-threaded-dev ant openjdk-7-jdk\
   libvirt-dev libcurl4-dev dhcp3-server vblade apache2 unzip curl vlan\
   bridge-utils libvirt-bin kvm sudo vtun

Please, consult the distribution-specific pages for detailed installation instructions.

Tools for interacting with Eucalyptus:

To interact with Eucalyptus, you need to install EC2-compatible command-line
tools. The instructions in Eucalyptus documentation rely on the euca2ools
command-line tools distributed by the Eucalyptus Team. Many other third-party
tools can also be used for some of the tasks, as described on the ecosystem
page.

2. Download Eucalyptus and supplied dependencies
================================================
In what follows substitute the desired version (e.g., 2.0.1) for $VERSION
either manually or by setting a shell variable.

Download either

    * eucalyptus-$VERSION-src.tar.gz (Eucalyptus source with included java libraries)

or

    * eucalyptus-$VERSION-src-online.tar.gz (Eucalyptus source that will download java libraries at build-time)

and for both

    * eucalyptus-$VERSION-src-deps.tar.gz (Eucalyptus C library dependency packages)

All packages can be found on the Eucalyptus Web site:

    * http://open.eucalyptus.com/downloads

Unpack the Eucalyptus source:

tar zvxf eucalyptus-$VERSION-src.tar.gz

Now you should have a directory eucalyptus-$VERSION. To simplify the remainder
of the installation, define EUCALYPTUS_SRC environment variable to be the top
of the source tree of eucalyptus and the variable EUCALYPTUS to be the
directory where eucalyptus will be installed (we recommend using
/opt/eucalyptus/):

cd eucalyptus-$VERSION
export EUCALYPTUS_SRC=`pwd`
export EUCALYPTUS=/opt/eucalyptus

3. Build Dependencies
=====================
To install Eucalyptus, you need to build packages that Eucalyptus depends on,
which we provide in the above-mentioned package
eucalyptus-$VERSION-src-deps.tar.gz. For the sake of this discussion, we are
going to assume that all packages have been untarred inside
"$EUCALYPTUS_SRC/eucalyptus-src-deps/" as above and will be installed in
"$EUCALYPTUS/packages".

Unpack the dependencies and create the directory you'll use to install them:

cd $EUCALYPTUS_SRC
tar zvxf ../eucalyptus-$VERSION-src-deps.tar.gz
mkdir -p $EUCALYPTUS/packages/

Build and install the dependencies. The following instructions work on some
Linux distributions, but aren't universal. Please, consult the documentation
for the specific packages for help with building them on your distribution.

a. Axis2
--------
cd $EUCALYPTUS/packages
tar zxvf $EUCALYPTUS_SRC/eucalyptus-src-deps/axis2-1.4.tgz

b. Axis2/C
----------
To compile Axis2/C, you will need to locate development headers for Apache and
for APR. On some distributions (e.g., Ubuntu and Debian) the following values
    should work:

export APACHE_INCLUDES=/usr/include/apache2
export APR_INCLUDES=/usr/include/apr-1.0

On CentOS 5, the headers should be in the following location:

export APACHE_INCLUDES=/usr/include/httpd/
export APR_INCLUDES=/usr/include/apr-1/

while on OpenSuse 11 you may find them at:

export APACHE_INCLUDES=/usr/include/apache2/
export APR_INCLUDES=/usr/include/apr-1/

With the two environment variables set, you can build and install Axis2/C as follows:

export AXIS2C_HOME=$EUCALYPTUS/packages/axis2c-1.6.0
cd $EUCALYPTUS_SRC/eucalyptus-src-deps/
tar zvxf axis2c-src-1.6.0.tar.gz
cd axis2c-src-1.6.0
CFLAGS="-w" ./configure --prefix=${AXIS2C_HOME} --with-apache2=$APACHE_INCLUDES \
    --with-apr=$APR_INCLUDES --enable-multi-thread=no
make ; make install

c. Rampart/C
------------
export AXIS2C_HOME=$EUCALYPTUS/packages/axis2c-1.6.0
export LD_LIBRARY_PATH=${AXIS2C_HOME}/lib:$LD_LIBRARY_PATH
cd $EUCALYPTUS_SRC/eucalyptus-src-deps/
tar zvxf rampartc-src-1.3.0-0euca1.tar.gz
cd rampartc-src-1.3.0
./configure --prefix=${AXIS2C_HOME} --enable-static=no --with-axis2=${AXIS2C_HOME}/include/axis2-1.6.0
make ; make install

Next, change the following in $AXIS2C_HOME/axis2.xml. In the 'inflow' section, change:

        <!--phase name="Security"/-->

to

        <phase name="Security"/>

In the 'outflow' section, change:

        <!--phase name="Security"/-->

to

        <phase name="Security"/>

4. Building Eucalyptus
=======================
First, make sure JAVA_HOME is defined. For example, on Centos 5:

export JAVA_HOME="/usr/lib/jvm/java-openjdk/"
export JAVA="$JAVA_HOME/JRE/bin/java"

then, build Eucalyptus:

cd $EUCALYPTUS_SRC
./configure --with-axis2=$EUCALYPTUS/packages/axis2-1.4 \
    --with-axis2c=$EUCALYPTUS/packages/axis2c-1.6.0 \
    --enable-debug --prefix=$EUCALYPTUS
make ; make install

5. Deploying Eucalyptus
=======================
At this point, if you plan to use Eucalyptus on more than one node, you're
ready to push the software out to the other nodes (although not all software
components are required on all nodes, it is simpler to just mirror everything
and selectively enable components via start-up scripts). If you installed
Eucalyptus in its own directory, you can just sync the entire package to all of
the hosts listed above using whatever mechanism you typically use to push
changes to nodes (rsync, for instance).

rsync -a $EUCALYPTUS/ root@{node-host-1}:$EUCALYPTUS/
rsync -a $EUCALYPTUS/ root@{node-host-1}:$EUCALYPTUS/
...

On installations without a root user, such as Ubuntu, it may be easier to pull
the software from each node one at a time:

node1# rsync -a {user}@{front-end}:$EUCALYPTUS/ $EUCALYPTUS/
node2# rsync -a {user}@{front-end}:$EUCALYPTUS/ $EUCALYPTUS/
...

NOTE: Installing Eucalyptus in the same directory on all nodes will make it
easier to manage it, so we strongly advise you to do so.

6. Configure Hosts

a. Set up a 'eucalyptus' user on all machines
---------------------------------------------
Eucalyptus will run as regular user on your systems, which you'll need to add
before running Eucalyptus (we will use eucalyptus) on all machines. For most
distributions, this task is accomplished by running the command:

useradd eucalyptus

For OpenSUSE, use:

groupadd eucalyptus
useradd eucalyptus -m -g eucalyptus

b. Configure your hypervisor
----------------------------
Ensure that this user can control your hypervisor through libvirt on all
compute nodes. On some distributions, this can be accomplished by adding
eucalyptus to group libvirt or libvirtd in file /etc/group. Please consult the
documentation for libvirt on your distribution for instructions. See Hypervisor
Configuration for more detailed information.

c. Configure your network
-------------------------
Eucalyptus provides several networking modes from which to choose, depending on
your local network setup, capabilities, and the networking features that you
wish to take advantage of within Eucalyptus. Most networking options require
that, on your node controllers, the primary interface is configured to be a
bridge (this is the default configuration with some distribution's Xen
hypervisor configuration). See Network Configuration for more information and
set-up instructions. Once you have decided which network mode you will be
using, you may be required to set up ethernet bridges on Eucalyptus component
machines. Example bridge configuration steps can be found here.

d. Configure Eucalyptus components
----------------------------------
On your compute nodes, create a local directory where VM images are to be
placed temporarily while VMs are running (images will be cached under the same
path, too). It is important that the directory is empty as everything in it
will be removed. Be sure to pick a partition with ample disk space as VM images
can be large. We use /usr/local/eucalyptus in the example below.

Place the mandatory parameters (including the type of hypervisor you plan to
use) into the configuration file and set up the permissions on Eucalyptus files
appropriately on all nodes. Both tasks can be accomplished with flags to
euca_conf tool:

    * -d specifies the root of Eucalyptus installation ($EUCALYPTUS)
    * --hypervisor specifies the hypervisor ('xen' or 'kvm')
    * --instances specifies where, on compute nodes, instance files will be stored
    * --user specifies the user that you created for running Eucalyptus
    * --setup invokes the first-time setup tasks

$EUCALYPTUS/usr/sbin/euca_conf -d $EUCALYPTUS --hypervisor kvm \
    --instances /usr/local/eucalyptus --user eucalyptus --setup

e. Distribution-specific post configuration steps
-------------------------------------------------
Some linux distributions require that the admin perform a few extra steps
before bringing up Eucalyptus. This section details some of these steps:

For Ubuntu, apparmor needs to be configured to allow dhcpd3 to write to the
filesystem. Add the following lines to '/etc/apparmor.d/usr.sbin.dhcp3':

/opt/eucalyptus/var/run/eucalyptus/net/ r,
/opt/eucalyptus/var/run/eucalyptus/net/** r,
/opt/eucalyptus/var/run/eucalyptus/net/*.pid lrw,
/opt/eucalyptus/var/run/eucalyptus/net/*.leases* lrw,
/opt/eucalyptus/var/run/eucalyptus/net/*.trace lrw,

where you substitute '/opt/eucalyptus' with the path to where you have chosen
to install Eucalyptus. Then, restart apparmor (NOTE: sometimes changes don't
take effect right away - either wait or reboot the system to be sure):

/etc/init.d/apparmor stop
/etc/init.d/apparmor start

Also, since Ubuntu DHCP daemon is configured to run as 'dhcpd' and not root,
ensure that the following two variables are set as follows in the
$EUCALYPTUS/etc/eucalyptus/eucalyptus.conf file on the Cluster head-node:

VNET_DHCPDAEMON="/usr/sbin/dhcpd3"
VNET_DHCPUSER="dhcpd"

At this point you should be ready to start Eucalyptus processes on all nodes
but before doing so you may want to configure the Eucalyptus network: you can
read more about it at Network Configuration.

f. Configure your startup scripts
---------------------------------
If you want to have eucalyptus started automatically when your machines are
(re)booted, you can add the following symlinks on the appropriate hosts: add
eucalyptus-cloud on the Cloud head-node, add eucalyptus-cc on the Cluster
head-node(s), and add eucalyptus-nc on the compute node(s)

ln -sf $EUCALYPTUS/etc/init.d/eucalyptus-cloud /etc/init.d/eucalyptus-cloud
ln -sf $EUCALYPTUS/etc/init.d/eucalyptus-cc /etc/init.d/eucalyptus-cc
ln -sf $EUCALYPTUS/etc/init.d/eucalyptus-nc /etc/init.d/eucalyptus-nc

and then add the symlinks to the distribution's booting process. This process
differs from distribution to distribution. For example if you have update-rc.d
available you can run:

update-rc.d eucalyptus-cloud defaults

or if you have chkconfig available you can run:

chkconfig eucalyptus-cloud on

7. Running Eucalyptus
=====================
Eucalyptus comes with the euca_conf script for configuring Eucalyptus. For some
requests it modifies the configuration file located in
'$EUCALYPTUS/etc/eucalyptus/eucalyptus.conf' (which can also be edited
manually), for other requests it modifies the database maintained by the Cloud
Controller (much of that functionality is duplicated in the Web interface, to
be described later).

In addition to modifying the configuration, euca_conf attempts to synchronize
x509 credentials across the nodes of a Eucalyptus installation by relying on
rsync and scp. We highly recommend setting up password-less SSH access for the
root user across all nodes of your Eucalyptus installation (otherwise,
euca_conf will prompt you for remote system passwords).

As explained in the overview, a Eucalyptus installation consists of five types
of components: cloud controller (CLC), Walrus, cluster controller (CC), storage
controller (SC), and the node controller(s) (NCs). In following instructions we
assume that all components except the NCs are co-located on one machine that we
refer to as the front end and that NCs run on one or more other machines
referred to ascompute nodes.

To run Eucalyptus, first, make sure that you have all of the runtime
dependencies of Eucalyptus installed, based on your chosen set of configuration
parameters. If there is a problem with runtime dependencies (for instance, if
Eucalyptus cannot find/interact with them), all errors will be reported in log
files located in $EUCALYPTUS/var/log/eucalyptus. For more information on
Eucalyptus log files and error reports, please see Troubleshooting Eucalyptus.

Next, inspect the contents of $EUCALYPTUS/etc/eucalyptus/eucalyptus.conf
carefully, on each machine, to make sure that the settings are appropriate for
your environment. Once you have confirmed that everything is configured
properly, enable the cloud services on the front-end:

# enable services on the front-end
$EUCALYPTUS/usr/sbin/euca_conf -d $EUCALYPTUS --setup
$EUCALYPTUS/usr/sbin/euca_conf -d $EUCALYPTUS --enable cloud --enable walrus --enable sc

BEFORE STARTING EUCALYPTUS SERVICES! If you are upgrading from Eucalyptus 1.6.2
to Eucalyptus 2.0, return now to the Upgrade Instructions, and proceed with
running the upgrade commands for the front-end and nodes as specified. If you
are performing a first-time installation, you may proceed with the following
steps and start Eucalyptus services:

Start each component on the appropriate host.

# start enabled front-end services
$EUCALYPTUS/etc/init.d/eucalyptus-cloud start

# start the cluster controller
$EUCALYPTUS/etc/init.d/eucalyptus-cc start

And on each of the compute nodes run:

$EUCALYPTUS/etc/init.d/eucalyptus-nc start

To stop them you call the script with stop instead of start.

NOTE: if you later decide to make changes to
$EUCALYPTUS/etc/eucalyptus/eucalyptus.conf that will effect the
cluster-controller, make sure to use the 'cleanstart', 'cleanstop', and/or
'cleanrestart' directives to the init scripts (as opposed to
start/stop/restart). This will both remove all existing CC state, and will
cause it to re-read the configuration file.

Something went wrong with that request. Please try again.
