Eu comprei recentemente um vps e tentei criar um script de inicialização / reinicialização para iniciar o meu programa java. Estou executando o CentOS 6. O script funciona se eu o executar manualmente com este comando:
service policyserver start
Mas não é executado automaticamente, cria um arquivo no /tmp/test.log com o seguinte erro:
Starting Policy Server: failed
Aqui está o script de inicialização dentro de /etc/init.d/
#!/bin/bash
#
#policyserver: Startup script for CamSpark Policy Server Application.
#
#chkconfig: 3 80 05
#description: Startup script for Cam Spark Policy Server Application.
CAMSPARK_POLICY_HOME=/tools/camsparkserver/Policy;
export CAMSPARK_POLICY_HOME
start() {
echo -n "Starting Policy Server: "
$CAMSPARK_POLICY_HOME/Policy.sh start >> /tmp/test.log
sleep 2
echo "done"
}
stop() {
echo -n "Stopping Policy Server: "
$CAMSPARK_POLICY_HOME/Policy.sh stop
echo "done"
}

echo $"Usage: policyserver {start|stop|restart}"

Alguém sabe qual poderia ser o problema?

Você pode depurar um problema como este executando o script de início de maneira mais detalhada.
$ bash -x service policyserver start
Você pode querer capturar essa saída para um arquivo de log também.
$ bash -x service policyserver start |& tee policyserver_startup.log
Você pode então passar pelo arquivo de log e ver qual comando está falhando.
