Create a new database in MySQL with name: ppion. Can be anything, doesn't need to be ppion, but make sure to assign the database name in application/config/database.php (the database name you created in the mysql should be the same as the database name you define in database.php file).

Open Terminal (Unix/Mac).

Go to application directory in the root folder of this app.

Run this: php doctrine.php orm:schema-tool:create

If no error, the tables should be created in the database.

Dump/import the file sqls/sql-acl.sql to the database.

Populate the database with some dummy data (sqls/ppion-dummy.sql), for example using phpmyadmin.

Open /Applications/MAMP/conf/apache/httpd.conf file.

Add the following at the end of the file:

NameVirtualHost *
<VirtualHost *>
    ServerName ppion.local
    DocumentRoot /path/to/root/folder/of/this/app

    SetEnv APPLICATION_ENV "development"

    <Directory /path/to/root/folder/of/this/app>
        DirectoryIndex index.php
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

Save it.

Edit the host database of your Mac in /etc/hosts file. You will need root access.

Add ppion.local after the localhost. For example,

127.0.0.1       localhost ppion.local

Flush the DNS by running this: dscacheutil -fluscache

Restart Apache.

Open browser then go to http://ppion.local:8888/
