Get it from here: http://sourceforge.net/projects/ajaxplorer/files/pydio/stable-channel/

Eg:

wget -O pydio-core-5.0.4.tar.gz http://sourceforge.net/projects/ajaxplorer/files/pydio/stable-channel/5.0.4/pydio-core-5.0.4.tar.gz/download

Extract the file to a chosen directory.

tar xf pydio-core-5.0.4.tar.gz
mv pydio-core-5.0.4 /var/www/explore
chown -R www-data /var/www/explore/data/

Install mysql-server if not already installed.

apt-get install mysql-server-5.5

Install mcrypt, php5-gd, php5-mysql:

apt-get install php5-mcrypt php5-gd php5-mysql

Now, add “AllowOverride All” to /etc/apache2/sites-available/default

<Directory "/var/www/explore">
                    AllowOverride All
 </Directory>

Restart apache2:

service apache2 restart

Create a mysql database, then a user and assign a password for the user on the database.

mysql -u root -p

And the following on the mysql shell.

CREATE DATABASE IF NOT EXISTS pydiodbase;
CREATE USER 'pydiouser'@'localhost' IDENTIFIED BY 'yourpassword';
GRANT ALL PRIVILEGES ON pydiodbase.* TO 'pydiouser'@'localhost';
FLUSH PRIVILEGES;

To change password of the dbuser:

UPDATE mysql.user SET Password=PASSWORD('yourpassword') WHERE User='pydiouser';

Then, access the web install at http://yourip/explore, and follow the onscreen prompts.

Your files appear in ./data/files/

Troubleshoot:
Error message during installation:

It seems that your data/ folder is not correctly protected, and that subfolders (like the data/cache/ folder) are web-accessible. If you are using Apache, make sure the AllowOverride All option is active for your current directory. If you are running Windows IIS, you must manually add a RequestFiltering/HiddenSegments configuration to prevent web access to these folders. If you have defined a different AJXP_DATA_PATH pointing outside the webfolder, you can ignore this warning.

Solution:
Check the default apache config:


ServerAdmin [email protected]
DocumentRoot /var/www

Options FollowSymLinks
AllowOverride None


Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all

ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/

AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all

ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined

In the code:


Options Indexes FollowSymLinks MultiViews
AllowOverride none
Order allow,deny
allow from all

change none to All:

Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all

Warning about locale not set:

dpkg-reconfigure locales
Generating locales...
  en_IN.UTF-8... up-to-date
Generation complete.

Now, 

grep -in AJXP_LOCALE conf/bootstrap_conf.php
30: * define("AJXP_LOCALE", "");
32://define("AJXP_LOCALE", "en_EN.UTF-8");
33://define("AJXP_LOCALE", "");

And edit line 33 of the file to change it to:

33:define("AJXP_LOCALE", "en_IN.UTF-8");

Warning: PHP Output Buffer disabled
You should disable php output_buffering parameter for better performances with Pydio.

Solution:
Check php value:

#grep -in output_buffering /etc/php5/apache2/php.ini
126:; output_buffering
245:output_buffering = 4096

Edit it to:

245:output_buffering = Off

Restart apache2 when you’re done.
