If you are comfortable setting up an Apache webserver and a MySQL database, then setting up ARK is very easy. Follow the guide below to get your ARK instance installed and set up.
If you are unfamiliar with the setup and administration of webservers along with the security risks to your system and data this entails, please consider contacting the ARK team to acquire a fully running ARK.
There are some further resources for learning about ARK and how to install it and some of the required dependencies on the ARK website.

Download the latest source code from http://sourceforge.net/projects/arkdb/ sourceforge.
ARK requires the following open source software packages to be installed on your server:
- PHP 5.4
ARK is able to connect to any WMC/WFS compliant server of geographic information. Mapserver is no longer an ARK dependency. This means that that administrators can connect to a geographic database of their choice, to suit their needs. Details on Mapserver setup can be found on their website.
ARK 1.1 requires PHP 5.4 or later. PHP 5.5 will run ARK but will produce "deprecated" errors as some functions used in ARK have been deprecated as of 5.5. If you are using PHP 5.5 and see deprecated messages, these can be hidden by following the relevant PHP documentation. These functions will be updated in a future release of ARK.
ARK runs on top of these packages and does not provide any set up of them or additional security to them. If you are using your server exposed to the internet, it is essential that you follow good standard security practice for the configuration of your packages. This setup is outside of the scope of this documentation and you are advised to undertake your research carefully.
In addition the following packages are useful:
Once you have Apache and MySQL running, phpMyAdmin is a very convenient tool for administering databases. More information on how to use phpmyadmin can be found on their website.
On most Linux distributions these packages will be installed by default.
Most Linux distros include an Apache webserver. Consult the documentation on your installation for instructions on how to configure your server. If your service path is configured, the service can be started with:
sudo service httpd start
If you need to install Apache, instructions can be found on their website.
Most Linux distros include PHP. Make sure that the version number of PHP installed on your system matches the requirements of ARK.
If you need to install PHP, instructions can be found on their website.
MySQL is included in many Linux distros, but if you do not have it you may need to install mysql-server and mysql, instructions are available on the MySQL website.
You will need to secure the installation,
OSX or WINDOWS
There are several ways to manually install each of the required packages on OSX or Windows. These methods will work perfectly well with ARK and if you are comfortable installing and configuring the required packages, please go ahead and do so. For OSX the instructions will be similar to the Linux instructions.
If you would prefer a simple package based installer, please consider using either WAMP/MAMP or if you are using Windows, MS4W also provides a good way to install a complete WAMP stack along with a Mapserver instance.
This package provides a standalone WAMP stack with a Mapserver instance. We have provided some walk through guidance on the ARK website for installing this package.
The ARK download consists of an SQL file and a folder of the php code and configuration files. All you need to do is to copy the arkv1_1 folder into the desired location in your webserver directory. Consult the documentation of your distribution if you are unsure where this is. It is likely to be something like
You should then rename the ark package's folder to your desired name. Make a note of the folder name because you will need to update the environment settings to match it. This folder name will be used to navigate your ARK using your browser (in the URL), so call it something short, easy to remember and unique to your installation.
Create Database and User
You now need to create a new database, import the SQL into it and create a new user on your MySQL server.
The basic ARK database is included in the ARK package as an SQL file.
ARK only requires one user on the database, this is the user that the php code will use to access the MySQL database. Actual end users of your ARK will be created later using the tools provided by ARK.
The easiest way to accomplish these steps is to use phpMyAdmin, but you can also accomplish it using the command line mysql tools:
Use the phpMyAdmin interface to create the new database. This is the database that will contain your ARK data, so make a note of the name so that you can update the settings files to match.
Now create a new user and grant them privileges on the new database.
Import the arkv1_1.sql file from the ARK source code into your database. Select the newly created database and then go to the Import tab and Browse to the .zip file that contains the SQL statement. This will copy all of the relevant tables to the database.
Using the Command Line
You can use MySQL from the command line to add the 'arkuser' user to the MySQL installation for instance:
CREATE USER arkuser'@'%' IDENTIFIED BY 'XXXXXX'; GRANT ALL PRIVILEGES ON *.* TO 'arkuser'@'%' WITH GRANT OPTION;
The values in this must be changed in order to secure your database. See the mysql manual for more information.
You will also need to create a database for your ARK to connect to.
CREATE DATABASE arkv1_1
You are encouraged to change these default names see the mysql manual for more information.
You should now load the ARK SQL into your database by using the
Source command on the mysql terminal specifying the location of the arkv1_1.sql file.
Once you have created the database and user, you should update your settings files
You will need to edit some of the configuration directives in the settings files located inside the
config folder of your ARK installation.
Start with the general
You can update the name of your ARK, this value will be used as the markup nickname (nname) for a piece of markup containing the human readable name of your ARK. This allows you to customise the name of your ARK as it appears in page headers and titles. You will now need to add the markup to the ARK database.
You should also set your default site code in this file. Make a note of your site code(s) and be sure to add them to the ARK database using the form provided in the data entry page as soon as you log in. You will now need to add the site code to the ARK database.
Next edit your
env_settings.php file. This file should be self-explanatory, however there is an explanation of the relevant settings on this wiki page.
Change the $server flag on line 52 to match your server type, either mac, windows or linux.
Then in the correct code block, alter the paths to match the locations of the relevant directories in your ARK environment.
Make sure that the various path directives are correct. Be aware that you should update these to match your new ark folder name as set up earlier. For example:
// The folder name of THIS instance of ARK (relative to the domain) $ark_dir // The server path to the ark directory $ark_server_path // The path to the PEAR installation $pear_path
Both local and remote paths for OpenLayers are offered, use // to comment out the line that you are not using.
Alter the database settings at the end of the file to match the database and user that you created earlier.
You are now ready to connect to your ARK!
Point your browser to the preflight checks file included in ARK to test that you have configured ARK correctly. It should be available on your server at www.example.com/'your ark directory'/config/preflight_checks.php. Depending on your setup you may be able to access it at localhost. Check your server documentation for details.
This tool will list set up options with either PASS or FAIL. If your config FAILs please follow the instructions on the preflight checks page, or refer to other pages on the wiki for more details.
File Uploads and phMagick
It is highly likely that a standard ARK install will fail on some or all of the tests in this section of the pre-flight tests.
If you intend to upload files such as PDFs or images to your ARK and would like them to have thumbnails, then you will need to pass all of these tests. If not, then ignore this section of the tests.
For further information on how to install the required PHP extensions, imageMagick and phMagick, please consult the relevant online documentation.
Browse to your ARK
Point your browser to the newly created ARK directory, typically this would be
localhost/ark_dir/ although the exact URL will vary according to both your hostname and your ARK directory settings.
After browsing to the ARK directory you should see the login pages for the new ARK system. The default ARK is created with the following admin user account:
username: doe_jd password: janedoe
Log in using these details and then finalise your configuration.
You will now need to create a new user for yourself. Once you have created this new administrator, you should logout and log back in again using you new username.
You should now remove the default doe_jd user to prevent unauthorised access.
Now add markup for the ARK name you specified in the settings file.
Now add your default site code as specified in the settings file.
If you experience problems after following the steps above, there are a range of possible reasons that your local setup may not be correct. In order to display debug messages, go to your settings file and turn on debug by adjusting the settings from:
error_reporting(0); // Turn off all error reporting - USE THIS FOR PRODUCTION SITES //error_reporting(E_ALL); // Report all PHP errors (see changelog) - USE THIS FOR SETUP AND TESTING
//error_reporting(0); // Turn off all error reporting - USE THIS FOR PRODUCTION SITES error_reporting(E_ALL); // Report all PHP errors (see changelog) - USE THIS FOR SETUP AND TESTING
Once you have passed the pre-flight checks you should remove (delete or make inaccessible) this file so that it cannot be seen by unwanted users.
Remove the Jane Doe default user. This is to prevent unauthorised access to your ARK via this account
If you plan on using your ARK on an unsecured network (such as the Internet) you should consider how you intend to encrypt traffic between the users and the server. You should consider how you will be securing passwords and login credentials against various kind of attacks. Such security measures are important but are outside the scope of this install document.
