Esta é a minha primeira contribuição ao fórum, qualquer erro por favor me avisem. Este script surgiu da necessidade de auxiliar um colega  que está iniciando no mundo linux e precisava instalar o Zabbix em uma distro CentOS 6.

Está todo automatizado, inclusive as configurações da pagina web. Apenas por segurança altere as variáveis abaixo:

SENHA="123456";      # Essa é a senha que sera configurada no bando criado, nessa caso o zabbix
SENHAROOT="123456";  # Essa é a senha de root do mysql

• Download instalador_zabbix
• Enviar nova versão

Versão 2 - Enviado por fabio brigido em 30/11/2016

Changelog: Mudanças na estrutura do script sendo as principais:
- Mudança do banco mysql. Agora o script pede para inserir a senha na tela, não sendo mais necessária sua prévia inserção;
- Correção de bugs;
