+## 安装使用kafka ##
+
+Step 1: Download the code
+
+    >tar -xzf kafka_2.12-1.1.0.tgz
+    >cd kafka_2.12-1.1.0
+
+
+Step 2: Start the server
+
+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.
+
+    >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:
+
+    > 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)
+
+Step 3: Create a topic
+
+Let's create a topic named "test" with a single partition and only one replica:
+
+    > bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
+
+We can now see that topic if we run the list topic command:
+
+    > bin/kafka-topics.sh --list --zookeeper localhost:2181
+    test
+
+Alternatively, instead of manually creating topics you can also configure your brokers to auto-create topics when a non-existent topic is published to.
+
+Step 4: Send some messages
+
+Kafka comes with a command line client that will take input from a file or from standard input and send it out as messages to the Kafka cluster. By default, each line will be sent as a separate message.
+
+Run the producer and then type a few messages into the console to send to the server.
+
+    > bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
+    This is a message
+    This is another message
+
+Step 5: Start a consumer
+
+Kafka also has a command line consumer that will dump out messages to standard output.
+
+    > bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
+    This is a message
+    This is another message
+
+If you have each of the above commands running in a different terminal then you should now be able to type messages into the producer terminal and see them appear in the consumer terminal.
+
+All of the command line tools have additional options; running the command with no arguments will display usage information documenting them in more detail.
