Linux安装kafka 分布式

下载kafka，地址：http://kafka.apache.org/downloads.html选择Binary
downloads下载

上传到linux并解压

$ tar -zxvf kafka_2.11-0.8.2.1.tgz

修改server.properties文件

$ vi config/server.properties

broker.id=1  (每台机器不能一样，我的另外两台机器写的是2，3)
host.name=192.168.10.117 (写服务器ip)
zookeeper.connect= 192.168.10.117:2181, 192.168.10.114:2181, 192.168.10.115:2181

启动zookeeper (安装略…..)

在每台机器上启动kafka 启动脚本在bin目录下

$ cd kafka_2.11-0.8.2.1/bin/
$ ./kafka-server-start.sh ../config/server.properties &

创建topic：创建topic：创建topic：

./kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 1 --topic mykafka

查看Topic：

./kafka-topics.sh --list --zookeeper localhost:2181

单机模式收发消息

发送消息：

./kafka-console-producer.sh --broker-list localhost:9092 --topic mykafka

接收消息：

./kafka-console-consumer.sh --zookeeper localhost:2181 --topic mykafka --from-beginning

发送消息和接收消息是在两个窗口

在发送消息窗口输入字符串，在接收消息窗口查看



分布式收发消息

发送消息：

./kafka-console-producer.sh --broker-list 192.168.10.114:9092 --topic mykafka

接收消息：

./kafka-console-consumer.sh --zookeeper 192.168.10.114:2181 --topic mykafka --from-beginning

写--from-beginning会显示历史消息，如果只想显示最新的可以不写

停止服务：

./kafka-server-stop.sh

报错和解决：

[2015-06-16 11:24:13,015] ERROR Failed to send requests for topics mykafka with correlation ids in [0,8] (kafka.producer.async.DefaultEventHandler)

这个错误是config/server.properties的host.name写的不对，可能是前面的“#”没有去掉或是写的主机名称，改成服务器ip地址就可以了，如果改成localhost单机模式不会有问题，但分布式的时候会报下面错误。
