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
- 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：
