（注：在大資料分析系統中，不會安裝單機版，所以可以直接去看多機版教程，多機版教程也是完整的。）

下載zookeeper：

安裝zookeeper：

將zookeeper-3.4.6.tar.gz拿U盤複製到/home/hadoop目錄下

cd /home/hadoop

開啟目錄/home/hadoop

tar -zxvf zookeeper-3.4.6.tar.gz -C /usr/local

解壓到指定目錄/usr/local

cd /usr/local

開啟目錄/usr/local

mv zookeeper-3.4.6 zookeeper

將zookeeper-3.4.6名字變為zookeeper

配置zookeeper

cd /usr/local/zookeeper

進入zookeeper目錄

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

複製一個備份

cd conf

進入conf目錄

vim zoo.cfg

編輯zoo.cfg

修改後的內容如下：

# 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=/usr/local/zookeeper/zkdata #這個目錄是預先建立的

# 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

紅色文字原來的內容

# do not use /tmp for storage, /tmp here is just 

# example sakes.

dataDir=/tmp/zookeeper

上面兩行的意思是：

不要使用/tmp/zookeeper作為目錄

因此，需要對它做出修改

建立上面需要的資料夾：

mkdir /usr/local/zookeeper/zkdata

啟動zookeeper：

具體指令如下所示：

[[email protected] conf]# cd ../

[[email protected] zookeeper]# cd bin

[[email protected] bin]# sh zkServer.sh start

JMX enabled by default

Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg

  7687 pts/0    S+     0:00 grep zookeeper

[[email protected] bin]# 

下載Kafka：

安裝Kafka：

將kafka_2.10-0.8.2.1.tgz拿U盤複製到/home/hadoop目錄下

cd /home/hadoop

開啟目錄/home/hadoop

tar -zxvf kafka_2.10-0.8.2.1.tgz -C /usr/local

解壓到指定目錄/usr/local

cd /usr/local

開啟目錄/usr/local

mv kafka_2.10-0.8.2.1 kafka

將kafka_2.10-0.8.2.1名字變為kafka

啟動Kafka：

cd /usr/local/kafka

開啟目錄

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

啟動

備註：要掛到後臺使用：sh bin/kafka-server-start.sh config/server.properties

因為執行資訊如下所示，執行結束後，將不能再輸入命令：

新建立一個TOPIC：

cd /usr/local/kafka/bin

開啟目錄

sh kafka-topics.sh --create --topic kafkatopic --replication-factor 1 --partitions 1 --zookeeper Slave1:2181

此時報了一堆錯誤，嘗試進行修改

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

此時，正確

顯示如下：

[[email protected] bin]# sh kafka-topics.sh --create --topic kafkatopic --replication-factor 1 --partitions 1 --zookeeper localhost:2181

Created topic "kafkatopic"

備註：要掛到後臺使用：

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

把KAFKA的生產者啟動起來：

 cd /usr/local/kafka/bin/

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

sh kafka-console-producer.sh --broker-list Slave1:9092 --sync --topic kafkatopic

顯示資訊如下所示：

[[email protected] hadoop]# cd /usr/local/kafka/bin/

[[email protected] bin]# sh kafka-console-producer.sh --broker-list localhost:9092 --sync --topic kafkatopic

[2015-09-09 11:06:54,831] WARN Property topic is not valid (kafka.utils.VerifiableProperties)

會出現一個警告

原教程中也出現，繼續

備註：要掛到後臺使用：

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

另開一個終端，把消費者啟動起來：

（這一步驟還在同一臺電腦或虛擬機器上操作）

cd /usr/local/kafka/bin/

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

此時也會報錯
並與原教材不符合，待尋找原因

此教程可用性存疑，開始配置多機器環境

在後續的文章中，這個問題得到了解決
