Basic premises for the hosting of a VHL site

This documento aims to describe the basic requirements for the hosting of a VHL. Hardware requirements are not included provided they depend on external factors such as: amount of installed applications, estimated amount of system users, data storage, memory and processing specific requirements.

Operating System

As any other application, it is required you have an operating system. This is the basic core for installing other software such as web server, PHP and the VHL model applications.

In BIREME, the standard operating system is OpenSUSE, a Linux flavor whose distribution is free and it has been chosen due to its stability and a broad capabality of setting up.

All VHL model's applications, as well as their pre-required software can be hosted under Windows and Linux.

Internet access

In order the VHL's applications can be accessible, it is essential to have an internet connection, all network infrastructure required (server's physical location, network cabling, net drivers well set etc), as well the hiring of an internet service provider.

This step depends on the previous step completely: installing and setting up the operating system.

Pre-required software

Note: We strongly recomment NOT TO USE preinstalled packages such as XAMPP and LAMP because they are intended to be used in development environments and are not set based on a secure environment required by production servers.

BIREME's applications have been tested and approved to run under Apache web server and PHP language, therefore being important the correct installing and setting up of both software so any VHL model application can be further installed.

BIREME makes available an installation and setting up manual of these pre-required software in its approved versions. The Installation manual of pre-required software to VHL applications.

ABCD specific requirements

To the specific case of ABCD, please take a look at ABCD.

Domain name for external browsing

The domain name aims to locate and identify one or more computer over the Internet, making it easier to memorize their addresses. Without this resource we would have to manage IP sequences. For further informatio, please go to Domain name.

Also, to announce and promote a VHL address, e.g.: Regional VHL, it is required to have a domain name registered and set accordingly. This process involves registering under one of the institutions that provide that service, the setting up of a web server and, lately its setting up into the DNS server.

Configuração do PHP

Para confirmar se os passos anteriores foram realizados com sucesso, desenvolvemos um script PHP para apresentar as configurações do ambiente criado. Este script deve ser colocado no diretório apontado como Document Root do Servidor Web, de forma a ser acessível por uma URL como no exemplo abaixo:

Supondo que o nome do script seja info.php

http://meudominio.bvs.br/info.php

O conteúdo deste script deve ser:

<?php phpinfo(); ?>

Se a página apresentada for parecida com esta abaixo, o processo foi realizado com sucesso.

Variações de Configuração

No caso da instância se destinar a instalação de BVS-site, DirEve ou LIS será necessário verificar a existência dos módulos de XML e XSL junto ao PHP, como orientado no manual de software pre-requisito. Por exemplo:

Para a maioria das aplicações da BVS, é necessário configurar o servidor - ou serviço de DNS - para que o mesmo saiba "resolver" o domínio das aplicações. Esta configuração é necessária porque muitas das aplicações fazem, internamente, chamadas HTTP para seu próprio endereço.

Esta configuração é facilmente testada pelo terminal de linha de comando do próprio servidor, com o comando PING:

$ ping meudominio.bvs.br
