#cd /opt/otrs/var/cron

2 - Vamos listar os arquivos para ver se os scripts estão dentro da pasta:

#ls

deverá aparecer os seguintes arquivos:

aaa_base.dist     generic_agent.dist       rebuild_ticket_index.dist
cache.dist      pending_jobs.dist      session.dist      fetchmail.dist
postmaster.dist      unlock.dist      generic_agent-database.dist
postmaster_mailbox.dist

Pode variar de acordo com a versão do OTRS em uso.

3-Vamos copiar os arquivos utilizando o comando abaixo:

#for foo in *.dist; do cp $foo`basename $foo .dist`; done

Feito isso você terá os scripts como backup.

4- Instalação do Cron do OTRS: Vamos entrar na pasta bin:

#cd /opt/otrs/bin/

Logar como usuário otrs: #su otrs

Executar o script:

./Cron.sh start

Voltaremos a conta de root do sistema: exit

Feitas as configurações acima vamos instalar o Cron do OTRS:

#crontab -l -u otrs Deverá aparecer o texto conforme abaixo:
