Step 2: Start the server
Step 2: 启动服务
Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don't already have one. You can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance.
运行kafka需要使用Zookeeper，所以你需要先启动Zookeeper，如果你没有Zookeeper，你可以使用kafka自带打包和配置好的Zookeeper。
> bin/zookeeper-server-start.sh config/zookeeper.properties [2013-04-22 15:01:37,495] INFO Reading configuration from: config/zookeeper.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig) ...
Now start the Kafka server:
现在启动kafka服务:
> bin/kafka-server-start.sh config/server.properties
[2013-04-22 15:01:47,028] INFO Verifying properties (kafka.utils.VerifiableProperties)
[2013-04-22 15:01:47,051] INFO Property socket.send.buffer.bytes is overridden to 1048576 (kafka.utils.VerifiableProperties)
...
官网中，提示很明显，先得开启zookeeper服务进程，再开启kafka服务进程。无论你是使用kafka自带的zookeeper还是外装的zookeeper集群。
(但是，单节点集群推荐使用自带的kafka，3或5或多集群推荐使用外装的zookeeper集群。）
Kafka使用Zookeeper所以你可能先要安装一个ZooKeeper.你可以使用kafka中打包好的脚本或者一个配置好的Zookeeper.
