When Dédalo is downloaded from GitHub, some config files should be configured with the proper parameters. All those config files come with a 'sample' prefix that need to be removed from the names to get the functionality.

The first step would be locating and renaming config files from their original value in GitHub to target file names that Dédalo can will locate and use. Some of these files may already be renamed, if you was followed the installation and configuration process and you will use the same server for the back-end and front-end, but if you want create a separate publication server you will need rename this files in the publication server.
Rename Dédalo config file
config4.php
This is the main config for all Dédalo system, this file is used to configure Dédalo when it is starting. In publication context, the main configuration will be used to get the diffusion domain in ontology and publish the information from PostgreSQL (back-end) to MySQL (front-end).
1
Locate the file into the directory: ../httpdocs/dedalo/lib/dedalo/config/
cd ../httpdocs/dedalo/lib/dedalo/config/
2
Rename the sample.config4.php to config4.php
mv sample.config4.php config4.php
Dédalo DB config file
config4_db.php
This config file set the Dédalo connection to databases. This file will be used to configure both PostgreSQL and MySQL databases connections. In publication context, this file will be used to connect the backend to MySQL.
1
Locate the file into the directory: ../httpdocs/dedalo/lib/dedalo/config/
cd ../httpdocs/dedalo/lib/dedalo/config/
2
Rename the file from sample.config4_db.php to config4_db.php
mv sample.config4_db.php config4_db.php
Rename public API server config file
server_config_api.php
This config file sets the public API server. This file will be used to configure all server parameters for the public API. It is independent from the back-end config files and has its own properties and DDBB connection. The API server files can be moved to other server machines, to create an independent space for the public websites because the server API is not connected to the back-end.
Public API is located in ../httpdocs/dedalo/lib/dedalo/publication/server_api/v1/ and it has its own config file.
1
Locate the file into the directory: ../httpdocs/dedalo/lib/dedalo/publication/server_api/v1/
cd ../httpdocs/dedalo/lib/dedalo/publication/server_api/v1/
2
Rename the config file from sample.server_config_api.php to server_config_api.php
mv sample.server_config_api.php server_config_api.php
