The OpenEarth infrastructure supports a bottom-up approach for long-term project-transcending collaboration adhering to four basic criteria:
- open standards & open source - The infrastructure should be based on open standards, not require non-libre software and be transferable
- complete transparency - The collected data should be reproducible, unambiguous and self descriptive. Tools and models should be open source, well documented and tested
- centralized access - The collection and dissemination procedure for data, models and tools should be web-based and centralized to promote collaboration and impede divergence
- clear ownership and responsibility - Although data, models and tools are collected and disseminated via the OpenEarth infrastructure, the responsibility for the quality of each product remains at its original owner.
To make the OpenEarth infrastructure work, the following ICT components are required in practice(see figure):
- a linux server (either virtual or real),
- a subversion server to enable version control, backup and controlled access,
- a tomcat6 server running an OPeNDAP protocol to provide netCDF files,
- an apache2 webserver to provide data visualisation files like *.kml for visualisation in Google Earth, and
- the OpenSSH protocol to facilitate remote access to the server (for maintenance purposes).
The remainder of this tutorial addresses the steps needed to set up this infrastructure.

it
...
is
...
finished
...
you
...
need
...
to
...
reboot
...
the
...
virtual
...
machine.
...
TIP:
...
UBUNTU
...
will
...
request
...
to

...
If
...
your
...
virtual
...
machine
...
does
...
not
...
start
...
up
...
properly
...
a
...
possible
...
cause
...
could
...
be
...
that
...
the
...
ISO
...
image
...
is
...
still
...
selected
...
in
...
the
...
CDROM/DVD
...
drive
...
(see
...
previous
...
steps).
...
Unselecting
...
it
...
is
...
likely
...
to
...
fix
...
this
...
problem.
...
The
...
virtual
...
machine
...
will
...
indicate
...
that
...
the
...
virtual

...
You
...
may
...
need
...
to

install
...
these
...
packages.
...
Once
...
subversion
...
package
...
is
...
installed
...
the
...
instructions
...
on
...
https://help.ubuntu.com/community/Subversion
...
can
...
be
...
followed
...
to
...
set
...
up
...
subversion
...
repositories.
...
A
...
user
...
'subversion'
...
needs
...
to
...
be
...
added
...
by
...
typing
...
the
...
following
...
command
...
in
...
a
...
terminal
...
window:
Code Block |
---|
} sudo adduser subversion {code} |
A
...
directory
...
can
...
be
...
created
...
where
...
new
...
repositories
...
can
...
be
...
put:
Code Block |
---|
} sudo mkdir /home/svn cd /home/svn {code} * |
Tip:
...
you
...
will
...
probably
...
want
...
to
...
select
...
a
...
more
...
appropriate
...
directory
...
for
...
actual
...
applications
...
(something
...
like
...
/var/data/repos/).
...
The
...
appropriate
...
location
...
depends
...
on
...
a
...
companies
...
local
...
preferences.
...
A
...
new
...
repository
...
is
...
created
...
by
...
issuing
...
the
...
following
...
commands:
Code Block |
---|
} sudo mkdir myproject sudo chown -R www-data:subversion myproject sudo chmod -R g+rws myproject sudo svnadmin create /home/svn/myproject sudo chmod -R g+rws myproject {code} |
In
...
each
...
repository
...
directory
...
uncomment
...
the
...
password
...
keyword
...
in
...
the
...
svn
...
config
...
file
...
"svnserve.conf"
...
and
...
add
...
usernames
...
and
...
passwords
...
to
...
the
...
passwordfile
...
"passwd".
...
Set
...
the
...
authentication
...
settings
...
to
...
your
...
preference:
...
e.g.
...
anon-access
...
=
...
none.
...
Tip:
...
Use
...
'sudo
...
gedit'
...
to
...
start
...
an
...
editor
...
program.
...
You
...
need
...
to
...
run
...
gedit
...
as
...
sudo
...
to
...
allow
...
filesaving.
...
To
...
start
...
the
...
svnservice
...
and
...
make
...
it
...
remotely
...
accessible
...
start
...
the
...
following
...
svnserve
...
with
...
the
...
following
...
command:
Code Block |
---|
} sudo svnserve -d --foreground -r /home/svn {code} or {code} |
or
Code Block |
---|
sudo -u www-data svnserve -d --foreground -r /home/svn
{code}
|
NB:
...
running
...
svnserve
...
in
...
the
...
foreground
...
the
...
cursor
...
will
...
not
...
reappear
...
(until
...
the
...
service
...
is
...
stopped
...
with
...
crtl-z)
...
so
...
don't
...
wait
...
for
...
it
...
to
...
reappear.
...
If
...
you
...
want
...
to
...
execute
...
another
...
command
...
start
...
a
...
new
...
terminal
...
window.
...
If
...
no
...
error
...
messages
...
appear
...
subversion
...
is
...
running
...
and
...
you
...
can
...
now
...
remotely
...
access
...
the
...
repositories,
...
e.g.
...
with
...
a
...
program
...
like
...
TortoiseSVN.
...
Besides
...
starting
...
svnserve
...
manually
...
and
...
running
...
it
...
on
...
the
...
foreground,
...
it
...
is
...
also
...
possible
...
to
...
make
...
svnserve
...
start
...
automatically
...
on
...
bootup
...
running
...
it
...
in
...
the
...
background.
...
Follow
...
the
...
instructions
...
on:
...
http://odyniec.net/articles/ubuntu-subversion-server/
...
under
...
the
...
section
...
"Svnserve
...
Initialisation
...
Script".
...
It
...
basically
...
comes
...
down
...
to
...
copying
...
the
...
info
...
from:
...
http://odyniec.net/articles/ubuntu-subversion-server/svnserve
...
to
...
a
...
file
...
(e.g.
...
using
...
gedit)
...
and
...
saving
...
it
...
as
...
"/etc/init.d/svnserve".
...
Make
...
sure
...
the
...
info
...
in
...
svnserve
...
is
...
edited
...
to
...
include
...
the
...
directory
...
you
...
selected
...
for
...
the
...
location
...
of
...
repositories.
...
The
...
script
...
is
...
installed
...
by
...
running:
Code Block |
---|
} sudo update-rc.d svnserve defaults {code} |
Indicate
...
your
...
repository
...
locations
...
(e.g.
...
/var/data/repos/)
...
in
...
the
...
svnserve
...
script:
Code Block |
---|
} DAEMON_ARGS="-d -r /var/data/repos" {code} |
To
...
make
...
sure
...
the
...
svnserve
...
script
...
is
...
executed
...
on
...
bootup
...
it
...
needs
...
to
...
be
...
made
...
executable
...
by:
Code Block |
---|
} sudo chmod +x /etc/init.d/svnserve {code} |
Subversion
...
should
...
now
...
work
...
and
...
you
...
should
...
be
...
able
...
to
...
commit
...
your
...
first
...
files.

location
...
of
...
your
...
repository
...
will
...
be
...
svn://
...
[ip-address

]
...
[repositoryname
...
].
...
You
...
can
...
find
...
the
...
IP

machine
...
under
...
the

via
...
a
...
webinterface.
...
However,
...
Thredds
...
will
...
want
...
to
...
write
...
logfiles.
...
The
...
standard
...
security
...
settings
...
on
...
your
...
virtual
...
machine
...
are
...
too
...
strict.
...
An
...
adjusted
...
.policy
...
file
...
should
...
be
...
added
...
in
...
"/etc/tomcat6/policy.d/"
...
with
...
the
...
following
...
content:
Code Block |
---|
} grant codeBase "file:${catalina.base}/-" { permission java.security.AllPermission; }; {code} |
Name
...
it
...
either
...
00openpolicy.policy
...
or
...
51openpolicy.policy
...
so
...
that
...
it
...
is
...
run
...
either
...
first
...
or
...
last
...
(this
...
is
...
indicated
...
by
...
the
...
two
...
digits
...
in
...
the
...
name).
...
Apparently
...
this
...
works.
...
NB:
...
A
...
number
...
that
...
is
...
not
...
first
...
or
...
last
...
still
...
results in problems.
Now download Thredds and mount the file 'thredds.war'
...
file
...
(NB:
...
file
...
should
...
have
...
this
...
exact
...
name)
...
by
...
accessing
...
http://\[ip-number\]:8080/manager/html
...
,
...
where
...
[ip-number
...
]
...
is
...
the
...
ip-number
...
of
...
your
...
virtual
...
server.
...
Once
...
you
...
deployed
...
the
...
war
...
file
...
a
...
new
...
option
...
will
...
appear
...
in
...
the
...
Tomcat6
...
management
...
webpage.
...
Select
...
'start'
...
to
...
start
...
the
...
Thredds
...
service.
...
Edit
...
in
...
"/var/lib/tomcat6/content/thredds"
...
the
...
file
...
"tomcat-users.xml".
...
Create
...
a
...
role
...
admin
...
and
...
manager
...
in
...
the
...
config.xml
...
and
...
create
...
a
...
user
...
(e.g.
...
admin)
...
and
...
assign
...
it
...
both
...
roles.

you
