kafka＋zookeeper环境配置（Mac 或者 linux环境）

一.zookeeper下载与安装

1）下载

adeMacBook-Pro:zookeeper_soft apple$ wget http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

2）解压

tar zxvf zookeeper-3.4.6.tar.gz

3）配置

cd zookeeper-3.4.6

cp -rf conf/zoo_sample.cfg conf/zoo.cfg

vim zoo.cfg

zoo.cfg:

# 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
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/Users/apple/Documents/soft/zookeeper_soft/zkdata #这个目录是预先创建的
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

4）启动zookeeper

adeMacBook-Pro:bin apple$ sh zkServer.sh start
JMX enabled by default
Using config: /Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../conf/zoo.cfg
-n Starting zookeeper ... 
STARTED
adeMacBook-Pro:bin apple$ ps ax| grep zookeeper.out 
10311 s003  S+     0:00.01 grep zookeeper.out
adeMacBook-Pro:bin apple$ ps ax| grep zookeeper
10307 s003  S      0:00.63 /usr/bin/java -Dzookeeper.log.dir=. -Dzookeeper.root.logger=INFO,CONSOLE -cp /Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../build/classes:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../build/lib/*.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../lib/slf4j-log4j12-1.6.1.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../lib/slf4j-api-1.6.1.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../lib/netty-3.7.0.Final.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../lib/log4j-1.2.16.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../lib/jline-0.9.94.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../zookeeper-3.4.6.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../src/java/lib/*.jar:/Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../conf: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /Users/apple/Documents/soft/zookeeper_soft/zookeeper-3.4.6/bin/../conf/zoo.cfg

二 下载并且安装kafka（预先得安装配置好scala的环境，Mac环境参照：http://www.cnblogs.com/super-d2/p/4534208.html）

1).下载kafka:

wget http://apache.fayea.com/kafka/0.8.2.1/kafka_2.10-0.8.2.1.tgz

2) 解压：

tar -zxf kafka_2.10-0.8.2.1.tgz

3）启动kafka

  adeMacBook-Pro:kafka_2.10-0.8.2.1 apple$ sh bin/kafka-server-start.sh config/server.properties

备注：要挂到后台使用：

sh bin/kafka-server-start.sh config/server.properties &

4)新建一个TOPIC

adeMacBook-Pro:bin apple$ sh kafka-topics.sh --create --topic kafkatopic --replication-factor 1 --partitions 1 --zookeeper localhost:2181

备注：要挂到后台使用：

sh kafka-topics.sh --create --topic kafkatopic --replication-factor 1 --partitions 1 --zookeeper localhost:2181 &

5) 把KAFKA的生产者启动起来：

adeMacBook-Pro:bin apple$ sh kafka-console-producer.sh --broker-list localhost:9092 --sync --topic kafkatopic

备注：要挂到后台使用：

sh kafka-console-producer.sh --broker-list localhost:9092 --sync --topic kafkatopic &

6）另开一个终端，把消费者启动起来：

adeMacBook-Pro:bin apple$ sh kafka-console-consumer.sh --zookeeper localhost:2181 --topic kafkatopic --from-beginning

备注：要挂到后台使用：

sh kafka-console-consumer.sh --zookeeper localhost:2181 --topic kafkatopic --from-beginning &

7）使用

1. 在发送消息的终端输入aaa，则可以在消费消息的终端显示，如下图所示：
