Drupal 7 on Ubuntu Maverick / Debian Lenny

Postgresql Support

1. Prepare the php environment:

sudo apt-get install php5-pgsql

For lenny it might be necessary to use the php version from dotdeb.org. UPDATE: In squeeze this is not necessary an more, because it comes already with php 5.3.

2. Prepare PostgreSQL

See Postgres_SQL on Ubuntu as described.

3. Create user and database

Install a database and user as described in the INSTALL.pgsql.txt file of the Drupal Installation.

Be sure to use the following syntax:

sudo su
su postgres -c "createuser --pwprompt --encrypted --no-createrole --no-createdb username"
su postgres -c "createdb --encoding=UTF8 --owner=username databasename"

I created a script, with does the job quiet well

#!/bin/bash

[ $UID -ne 0 ] && echo Have to be root.
[ $UID -ne 0 ] && exit

DATABASE="$1"
DATABASEUSER="$2"
CREATEUSER="$3"
DBSCHEMA="$4"

usage() {
echo 'Have to add: DATABASENAME DATABASEUSER (--nocreateuser|--createuser) [SCHEMA]'
echo 'DATABASENAME like:      db_mysite_com'
echo 'DATABASEUSER like:      blue_it_org'
echo 'Create a user or use an existing one:'
echo '                        --nocreateuser|--createuser'
echo 'SCHEMA must be unique with an underscoe < _ > at the end:'
echo '                        www_mysite_com_ | subdomain_mysite_com_'
exit 
}

[ "$3" = "" ]  && usage; 

db_schema_check() {
if echo -n ${DBSCHEMA} | fgrep -q "." 
then
	echo ""
	echo "ERROR in SCHEMA-Name: < ${DBSCHEMA}  >"
	echo ""
	echo "      Using of character < . > (point) is not allowed in SCHEMA definition."
	echo "      Use < _ > (underscore) instead"
	echo ""
	exit
fi
}

create_user() {
echo "Creating database user <${DATABASEUSER}>"
if su postgres -c "createuser --pwprompt --encrypted --no-createrole --no-createdb ${DATABASEUSER}"
then
	echo -n ""
else
        echo ""
        echo "If the error was due to an existing user, try parameter --nocreateuser"
        exit
fi
}

create_db() {
echo "Creating database <${DATABASE}> owned by user <${DATABASEUSER}>"
su postgres -c "createdb --encoding=UTF8 --owner=${DATABASEUSER} ${DATABASE}" || exit
}

create_schema() {
echo "Creating database schema <${DBSCHEMA}>"
su postgres -c "psql --dbname=${DATABASE} -c \"CREATE SCHEMA ${DBSCHEMA} AUTHORIZATION ${DATABASEUSER};\" ";
}

[ "${DBSCHEMA}" = "" ] || db_schema_check;

if [ "${CREATEUSER}" = "--createuser" ]
then 
	create_user;
	create_db;
fi

if [ "${CREATEUSER}" = "--nocreateuser" ]
then
	create_db;
fi

if [ "${DBSCHEMA}" = "" ]
then
	echo "NO database Schema will be created."
else
	create_schema;
fi

4. Edit the drupal configuration file as described in the INSTALL.txt like this

[...]
$databases['default']['default'] = array(
   'driver' => 'pgsql',
   'database' => 'db_name',
   'username' => 'db_user_name',
   'password' => 'db_pass',
   'host' => 'localhost',
   'prefix' => ,
);
$databases = array();
[...]

5. Edit an apache configuration file

<VirtualHost drupal7.localhost:80>
 NameVirtualHost  drupal7.localhost
 DocumentRoot /path/to/drupal7/

 <Directory "/path/to/drupal7/">
   Options ExecCGI FollowSymLinks
   DirectoryIndex index.php
   AllowOverride None
   Order allow,deny
   Allow from all
   DefaultType application/x-httpd-php

   RewriteEngine on
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

 </Directory>

</VirtualHost>

6. Start the installation within your webbrowser.

Drupal 7 Installation

Troubleshooting

Color module not working

File permissions has to be set to public !

Uploading files is not visible in the edit area

Check "content types" (german: Inhaltstypen) from the menu and activate the appropriate feature for the given content type (e.g. page, articel, blog, ...)

Contact form

* The contact form module has an entry in the "navigation" (!) menu which is NOT aktivated by default. Simply pput it e.g. into the secondary links.

PHP memory mimits

There are two ways to do this:

1. locally in your drupal installation

If error messages occur about memory limit when you try to install modules then edit sites/default/settings.php and add the following line:

ini_set('memory_limit',             '24M');

This sets memory limit on a per site basis.

The other way is to edit serverwide (!) apache's /etc/php5/apache2/php.ini and customize the value there. Image processing needs - for drupal 6 - a minimal amount of 96M memory size!

 memory_limit = 96M      ; Maximum amount of memory a script may consume (16MB)

2. server wide in php.ini

You can also set the memory limit server wide in the php.ini file of your webserver.

You can find it in the /etc/php5/apache2 directory.

Not satisfied with Translation (.po files)

Edit the .po files for the translation and add them via the translation module.

You can also add the following module which filters active content:

String Overrides

Alter Strings

Go to Setting->Translation and click to the Search button.

Search for

@username's blog

and add your own translation.

Cron

On your sit enable cron

crontab -e -u www-data

and enter a line like (45 runs every hour)

# m h  dom mon dow   command
 45 *  *   *   *     /usr/bin/lynx -source http://example.com/cron.php

or use wget to achieve the same:

  0 *  *   *   *     wget -O - -q -t 1 http://www.example.com/cron.php
