Estou usando alguns projetos do Apache, como o Apache Kafka e o Apache Zookeeper. A diferença entre dois é que quando eu emito o comando Apache Kafka no terminal, kafka-server-start.sh $KAFKA_HOME/config/server.conf gera logs e não retorna o controle da linha de comando (a nova linha que eu posso emitir algum outro comando). Mas, ao emitir o serviço de zookeeper após algum registro de linha, ele retorna o comando do terminal para mim.
Agora eu criei serviços para o Kafka e o Zookeeper para iniciar no momento da inicialização automaticamente. A seguir, o modelo para *.service files:
[Unit]
Description=Zookeeper Daemon
Wants=syslog.target
[Service]
Type=forking
WorkingDirectory=/home/zookeeper
User=zookeeper
ExecStart=/opt/zookeeper/bin/zkServer.sh start
TimeoutSec=30
[Install]
WantedBy=multi-user.target
O arquivo .service para o Kafka e o Zookeeper tem a mesma estrutura.
Iniciar o serviço do Zookeeper na inicialização é ok, mas o problema é quando o comando para iniciar o serviço Kafka é emitido, pois a estrutura de comando do Kafka não retorna o comando ao usuário, o systemd o considera como mal sucedido e depois de um tempo limite, rotule-o como um serviço com falha ou inativo! O systemd tem uma solução para executar esses comandos como um serviço?
