Drupal 7 on Ubuntu Maverick / Debian Lenny

Structure configuration

Blocks

1. Alter the login block

Replace the default login block with a new menu-item called login which points to /user/login. This will also assure, that - if you are using the #Secure Pages module - you will get a https login.

It will only show up, if you are logged out.

Modules configuration

This section shows how to configure the individual modules.

IMCE

1. Thumnail size

To get thumbnails like in drupal default settings (these can be viewed under configuration->media->image styles) go to configuration->media->imce->profile of User-1 and alter the "Thumbnails" settings according to the following values:

Name	Dimensions	Präfix	Suffix
Small	100x100		_100x100
Medium	220x200		_220x220
Large	480x480		_480x480

2. Secure pages

To function properly with https please see #Secure Pages

Secure Pages

Go to admin->structure and alter the secure pages sites to

[...]
admin
admin/*
imce
imce/*

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 aware: Using a database schema is NOT advised, because it breaks the update functionality of drupal 7. Instead using a prefix is possible.

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. The --nocreateuser parameter is used, when you are accessing different databases with one (existing) account.

#!/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};\" ";
}

#######################################################
# MAIN
#######################################################

[ "${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 Using prefix will result in tablenames with the assigned prefix. This is only necessary, if you are using the same database for more than one installation. If you use one database for one site, this is no problem.

[...]
$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. Edit your /etc/hosts

sudo gedit /etc/hosts

[...]
127.0.0.1 localhost drupal7.localhost
[...]

7. Start the installation within your webbrowser.

PHP

Uploadprogress and ACP

Thanks to joergfelser.at for this hint ...

If you are using Drupal 7 you will probably notice, that the system is not able to show an upload progress bar. You can fix this by installing the appropriate php modules and extensions:

apt-get install php5-dev php-apc
mkdir -p /tmp/pear/cache # BUG #619307: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=619307
pecl install uploadprogress
vim /etc/php5/apache2/php.ini

Scroll to the End of the file and add

; Uploadprogress for Drupal 7
apc.rfc1867 = 1
extension=uploadprogress.so

Restart the webserver

service apache2 restart

If you like to keep your production system more secure, uninstall the following packages:

apt-get remove autoconf automake1.4 autotools-dev binutils cpp cpp-4.1 gcc gcc-4.1 libc6-dev libssl-dev libssp0 libtool linux-kernel-headers php5-dev shtool zlib1g-dev

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
