下面是我如何配置Kafka在ubuntu 14.04上自动启动：

sudo su
cp -R ~/kafka_2.11-0.10.0.1 /opt
ln -s /opt/kafka_2.11-0.10.0.1 /opt/kafka

将以下init脚本复制到/etc/init.d/kafka：

DAEMON_PATH=/opt/kafka/
PATH=$PATH:$DAEMON_PATH/bin

# See how we were called.

case "$1" in
  start)
        # Start daemon.
        echo "Starting Zookeeper";
        nohup $DAEMON_PATH/bin/zookeeper-server-start.sh -daemon /$DAEMON_PATH/config/zookeeper.properties 2> /dev/null && \
        echo "Starting Kafka";
        nohup $DAEMON_PATH/bin/kafka-server-start.sh -daemon /$DAEMON_PATH/config/server.properties 2> /dev/null
        ;;
  stop)
        # Stop daemons.
        echo "Shutting down Zookeeper";
        pid=`ps ax | grep -i 'org.apache.zookeeper.server' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          kill -9 $pid
        else
          echo "Zookeeper was not Running"
        fi
        echo "Shutting down Kafka";
        pid=`ps ax | grep -i 'kafka.Kafka' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          kill -9 $pid
        else
          echo "Kafka was not Running"
        fi
        ;;
  restart)
        $0 stop
        sleep 2
        $0 start
        ;;
  status)
        pid=`ps ax | grep -i 'org.apache.zookeeper.server' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          echo "Zookeeper is Running as PID: $pid"
        else
          echo "Zookeeper is not Running"
        fi
        pid=`ps ax | grep -i 'kafka.Kafka' | grep -v grep | awk '{print $1}'`
        if [ -n "$pid" ]
          then
          echo "Kafka is Running as PID: $pid"
        else
          echo "Kafka is not Running"
        fi
        ;;
  *)
        echo "Usage: $0 {start|stop|restart|status}"
        exit 1
esac

exit 0

使用以下命令创建kafka服务：

chmod 755 /etc/init.d/kafka
update-rc.d kafka defaults

现在您应该可以像这样启动和停止Kafka服务：

sudo service kafka start
sudo service kafka status
sudo service kafka stop

如果以后要删除kafka服务，请运行 update-rc.d -f kafka remove .

一个简单的方法是使用systemd。您应该注意，在启动时，像javahome这样的环境变量还没有加载，所以我们应该将它们引入系统。一个好的解决方案是创建一个名为 profile 再加上所有必要的变量：

# /home/kafka/profile

JAVA_HOME=/opt/jdk8
KAFKA_HOME=/opt/kafka

假设你在路上安装了Kafka /opt/kafka ，为了在ubuntu启动后自动运行kafka（在ubuntu 16.04和centos7上测试过，我猜它在systemd支持的任何发行版上都能工作），请执行以下命令：

sudo nano /etc/systemd/system/kafka.service  # open file to add service informations

现在将以下内容添加到文件中

[Unit]
Description=Kafka Daemon
Wants=syslog.target

# suppose you have a service named zookeeper that it start zookeeper and we want Kafka service run after the zookeeper service

After=zookeeper.service

[Service]    
Type=forking

# the user whom you want run the Kafka start and stop command under

User=kafka    

# the file path that contains envirnment variables

EnvironmentFile=/home/kafka/profile

# the directory that the commands will run there

WorkingDirectory=/home/kafka/ 

# Kafka server start command

ExecStart=/opt/kafka/bin/kafka-server-start.sh -daemon /opt/kafka/config/server.properties

# Kafka server stop command

ExecStop=/opt/kafka/bin/kafka-server-stop.sh -daemon

TimeoutSec=30
Restart=on-failure

[Install]
WantedBy=multi-user.target

注意：由于kafka需要zookeeper在启动时连接它，我想我们也有一个zookeeper服务，我设置kafka服务在zookeeper服务启动后运行。
现在在保存 kafka.service 文件，只需运行以下命令来创建kafka服务的链接，它将在每次重新启动操作系统时启动：

sudo systemctl enable kafka

现在可以使用以下命令启动kafka服务：

sudo systemctl start kafka.service

并检查服务的状态：

sudo systemctl status kafka.service
