<div class =“post-text”itemprop =“text”> 以下是我如何配置Kafka在Ubuntu 14.04上自动启动： <pre> <code> sudo su cp -R ~/kafka_2.11-0.10.0.1 /opt ln -s /opt/kafka_2.11-0.10.0.1 /opt/kafka </code> </pre> 将以下init脚本复制到/etc/init.d/kafka： <pre> <code> 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 </code> </pre> 使用以下命令创建kafka服务： <pre> <code> chmod 755 /etc/init.d/kafka update-rc.d kafka defaults </code> </pre> 现在您应该可以像这样启动和停止kafka服务： <pre> <code> sudo service kafka start sudo service kafka status sudo service kafka stop </code> </pre> 如果您想稍后删除Kafka服务，请运行 <code> update-rc.d -f kafka remove </code> 。 </DIV>

<div class =“post-text”itemprop =“text”> 一种简单的方法是使用systemd。你应该注意在启动时环境变量如 JAVA_HOME 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的文件 <code> profile </code> 并添加所有必要的变量： <pre> <code> # /home/kafka/profile JAVA_HOME=/opt/jdk8 KAFKA_HOME=/opt/kafka </code> </pre> 假设你已经在路径上安装了Kafka <code> /opt/kafka </code> ，为了让Kafka在Ubuntu启动后自动运行（在Ubuntu 16.04和centOS7上测试，我猜它可以在systemd支持的任何发行版上工作）执行以下命令： <pre> <code> sudo nano /etc/systemd/system/kafka.service # open file to add service informations </code> </pre> 现在将以下内容添加到该文件中 <pre> <code> [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 </code> </pre> 的 注意： </强> 由于Kafka需要动物园管理员在开始时连接它，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。 现在保存后 <code> kafka.service </code> 文件，只需运行以下命令即可创建Kafka服务的链接，每次重启操作系统时都会启动它： <pre> <code> sudo systemctl enable kafka </code> </pre> 现在，您可以使用以下命令启动Kafka服务： <pre> <code> sudo systemctl start kafka.service </code> </pre> 并检查服务的状态： <pre> <code> sudo systemctl status kafka.service </code> </pre> </DIV>
