$ dd if=/dev/zero of=/swapfile bs=1024 count=1048576

$ mkswap /swapfile

Then edit /etc/fstab and add this line:

/swapfile none swap sw 0 0

To test the Python Image Library (PIL) I’d  executed this code on python console:

from PIL import Image
file = open("/tmp/logo.jpg")
image_test = Image.open(file)
image_test.load()

what output:

<PixelAccess object at 0x37dce100>

This is ok, but when I’d run the same code inside a Django view I got the error "decoding error when reading image file".

I checked the Python Path and it was the same for both console and Django Application.

After looking on google I discover a post from Peter Schoenster on “Django-Photologue“  wiki page saying he had the same problem and discovered that python shell was using one version of libjpeg and Apache was using other. (He, as me had two version of this library on the system). He discovered it using the command

# lsof | grep libjpeg

I just remove the old libjpe62 from my system using:

# apt-get remove libjpeg62

And everything works !

I’d founded the file ‘tk.h‘ on ‘/usr/include/tcl8.4‘ and after a look at the setup.py file I changed the line number 41 from:

TCL_ROOT = None

to

TCL_ROOT = “/usr/include/tcl8.4″

Now you can run your ‘python setup.py install’ again and get PIL working!

Note: You may perhaps have to install the tk-dev and tcl-dev packages before running the setup.py. I’d already had these packages, so I’m not sure about it.

On Ubuntu run:

apt-get install tk-dev tcl-dev

One of the best point of Satchmo is how easy and beautiful is to customize your application. You can create customized product model without touch the base Satchmo models. It’s a great feature, that make easy to apply future Satchmo updates.

You can learn how to create a custom product in JuanjoAlvarez Blog.

I followed the instructions but get the error:

Wed, 12 Aug 2009 11:57:17 configuration DEBUG SettingNotSet: PRODUCT.PRODUCT_TYPES
Traceback (most recent call last):
File "./manage.py", line 27, in
execute_manager(settings)
.
.
.
.
raise SettingNotSet('%s config group does not exist' % group)
livesettings.models.SettingNotSet

SOLUTION: After apply a grep in the Satchmo code for “PRODUCT_TYPES” I figured out my mistake: My package was named product: the same name of the Satchmo product application. So it was overriding the framework application.

Thank god Satchmo is a Open Source project!

You can get the PostgreSQL sources at http://www.postgresql.org/ftp/source/. I got the sources for the version 8.3.7, since it’s the latest stable version, so far.

Before installing the Postgres, first I have to install the readline library (I am using a Ubuntu 8.10 installed some days ago, maybe in a brand new installation you need to install some other packages):

# apt-get install libreadline5-dev

Then, extract the .tar.gz or .tar.bz2 file and inside the created directory run:

NOTE: The directory after the prefix argument (/opt/postgresql.org/…….) is where your postgres server will be installed, change it to wherever you want.

# ./configure --prefix=/opt/postgresql.org/postgresql-server/postgresql-8.3.7

And then:

# make

If everything goes well you’ll see the message :

All of PostgreSQL successfully made. Ready to install.

Now run:

# make install

Again, if everything goes well, the following message will be shown:

PostgreSQL installation complete.

So far, so good. Easy as said, but you still have some steps to do:

Create a new group and a new user to run the server:

# groupadd postgres
# useradd -g postgres -d /home/postgres -s /bin/bash -m postgres

Now create a directory to put the database files. You can choose any directory that you want. I use to put my variable size files on /var/local, so I create this one:

# mkdir /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data -p
# chown -R postgres:postgres /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data


Log as this user:

# su - postgres

edit the .bashrc file and append this to the end:

PATH=/opt/postgresql.org/postgresql-server/postgresql-8.3.7/bin:$PATH
export PATH

Run the following command:

$ source .bashrc

Now we are ready to create the database files.

$ initdb -D /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data

And then start the server (I’m using a tempory log file, you can choose other if you wish):

$ pg_ctl -D /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data -l /tmp/postgres.log start


See the log file to check if the server are ok.

Now stop the server:

$ pg_ctl -D /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data stop

The last thing: To start the server in system initialization copy the file linux from contrib/start-scripts/ to /etc/init.d/postgres. (Look in the sources directory)

Remember of change the permission of the file to 755:

# chmod 755 /etc/init.d/postgres

Open the file /etc/init.d/postgres on an editor and change the line with prefix to wherever you install the postgres (The same directory used in the prefix attribute from the configure command).

I had to change the following lines:

prefix=/opt/postgresql.org/postgresql-server/postgresql-8.3.7
PGDATA="/var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data"


Save the file and exit.
Now run:

# update-rc.d -f postgres defaults

To ensure that everything is ok run:

# /etc/init.d/postgres start

Check the file /var/local/postgresql.org/postgresql-server/postgresql-8.3.7/data/serverlog to verify that the server is up and ok.

Good job! You now have a brand new Postgres 8.3 server up and running!

One Tip: A lot of useful information can be found on file INSTALL inside the source directory. If you have some trouble installing Postgres take a look at this file.

One more tip: One great tool to work with Postgres Server is PgAdmin. You can find it in the Ubuntu Add/Remove Applications.

To install  (I’m using the version 2.0.10) you need to run two commands:

# python setup.py build

and after the build is complete:

# python setup.py install

Well, but it’s not so easy if you do not have the dependencies already installed.In my case I got errors like:

NameError: global name ‘w’ is not defined psycopg2

or

error: Setup script exited with error: command ‘gcc’ failed with exit status 1

To solve this I have to install the libpq-dev library and the python development package:

# apt-get install libpq-dev

# apt-get install python2.5-dev

After that I just run the usual python setup.py install and all done.

Workaround:

$ su - zimbra

$ zmprov mcf zimbraRemoteManagementPort <new port number>
