1、下载kafka
wget https://www.apache.org/dyn/closer.cgi?path=/kafka/0.8.2.1/kafka_2.9.2-0.8.2.1.tgz
2、解压
tar -zxf kafka_2.9.2-0.8.2.1.tgz
创建软连接
ln -s /opt/workspace/apps/kafka_2.10-0.8.2.1 /opt/workspace/kafka
3、修改配置文件
(1)kafka配置文件
cd /opt/workspace/kafka/config
vim server.properties
############################# Server Basics #############################
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0
############################# Socket Server Settings #############################
# The port the socket server listens on
port=9092
# Hostname the broker will bind to. If not set, the server will bind to all interfaces
# 修改为主机ip,不然服务器返回给客户端的是主机的hostname,客户端并不一定能够识别
host.name=10.205.28.4
############################# Log Basics #############################
# A comma seperated list of directories under which to store log files
# 日志目录
log.dirs=/var/log/kafka
#zookeeper地址和端口
zookeeper.connect=localhost:2181
(2)zookeeper配置
vim zookeeper.properties
# the directory where the snapshot is stored.
dataDir=/var/zookeeper
dataLogDir=/var/log/zookeeper
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=100
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
具体解释请参考：http://nanchengru.com/2015/04/zookeeper%E5%AE%89%E8%A3%85%E9%85%8D%E7%BD%AE%E4%BB%A5%E5%8F%8A%E5%91%BD%E4%BB%A4/
4、启动zookeeper和kafka
写了个脚本
#!/bin/sh
#启动zookeeper
zookeeper-server-start.sh ../config/zookeeper.properties > /var/log/zookeeper/zk-server-start.log &
#休眠3秒
sleep 3 #等3秒后执行下一条
#启动kafka
kafka-server-start.sh ../config/server.properties > /var/log/kafka/kafka-server-start.log &
5、使用kafka
Step 3: Create a topic（创建主题:test）
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 --zookeeper localhost:2181 --topic test --from-beginning
This is a message
This is another message
心得总结：
1.produce启动的时候参数使用的是kafka的端口而consumer启动的时候使用的是zookeeper的端口；
2.必须先创建topic才能使用；
3.topic本质是以文件的形式储存在zookeeper上的。
