Zookeeper+Kafka集群部署

主机规划：

10.200.3.85  　　Kafka+ZooKeeper

10.200.3.86  　　Kafka+ZooKeeper

10.200.3.87 　　 Kafka+ZooKeeper

软件下载地址：

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
wget http://mirror.bit.edu.cn/apache/kafka/1.1.0/kafka_2.12-1.1.0.tgz

三台主机hosts文件一致：

# cat /etc/hosts
10.200.3.85 ZooKeeper-Kafka-01
10.200.3.86 ZooKeeper-Kafka-02
10.200.3.87 ZooKeeper-Kafka-03

一、安装zookeeper

1.在master节点上操作：

[root@ZooKeeper-Kafka-01 src]# tar -zxvf zookeeper-3.4.10.tar.gz -C /usr/local/
[root@ZooKeeper-Kafka-01 src]# cd ..
[root@ZooKeeper-Kafka-01 local]# ln -s zookeeper-3.4.10 zookeeper
[root@ZooKeeper-Kafka-01 local]# cd zookeeper/conf/
[root@ZooKeeper-Kafka-01 conf]# cp zoo_sample.cfg zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/tmp/zookeeper
clientPort=2181
server.1=ZooKeeper-Kafka-01:2888:3888
server.2=ZooKeeper-Kafka-02:2888:3888
server.3=ZooKeeper-Kafka-03:2888:3888

2.创建dataDir目录创建/tmp/zookeeper

# 在master节点上

[root@ZooKeeper-Kafka-01 conf]# mkdir /tmp/zookeeper
[root@ZooKeeper-Kafka-01 conf]# touch /tmp/zookeeper/myid
[root@ZooKeeper-Kafka-01 conf]# echo 1 > /tmp/zookeeper/myid

3.将zookeeper文件复制到另外两个节点：

[root@ZooKeeper-Kafka-01 local]# scp -r zookeeper-3.4.10/ 10.200.3.86:/usr/local/
[root@ZooKeeper-Kafka-01 local]# scp -r zookeeper-3.4.10/ 10.200.3.87:/usr/local/

4.在两个slave节点创建目录和文件

#ZooKeeper-Kafka-02节点:

[root@ZooKeeper-Kafka-02 local]# ln -s zookeeper-3.4.10 zookeeper
[root@ZooKeeper-Kafka-02 local]# mkdir /tmp/zookeeper
[root@ZooKeeper-Kafka-02 local]# touch /tmp/zookeeper/myid
[root@ZooKeeper-Kafka-02 local]# echo 2 > /tmp/zookeeper/myid

#ZooKeeper-Kafka-03节点

[root@ZooKeeper-Kafka-03 local]# ln -s zookeeper-3.4.10 zookeeper
[root@ZooKeeper-Kafka-03 local]# mkdir /tmp/zookeeper
[root@ZooKeeper-Kafka-03 local]# touch /tmp/zookeeper/myid
[root@ZooKeeper-Kafka-03 local]# echo 3 > /tmp/zookeeper/myid

5.分别在每个节点上启动 zookeeper测试：

[root@ZooKeeper-Kafka-01 zookeeper]# ./bin/zkServer.sh start
[root@ZooKeeper-Kafka-02 zookeeper]# ./bin/zkServer.sh start
[root@ZooKeeper-Kafka-03 zookeeper]# ./bin/zkServer.sh start

6.查看状态：

[root@ZooKeeper-Kafka-01 zookeeper]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower
[root@ZooKeeper-Kafka-02 zookeeper]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: leader
[root@ZooKeeper-Kafka-03 zookeeper]# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: follower

至此zookeeper集群安装成功！！！

Kafka集群安装配置

1.安装：

[root@ZooKeeper-Kafka-01 src]# tar -zxvf kafka_2.12-1.1.0.tgz -C /usr/local/
[root@ZooKeeper-Kafka-01 src]# cd ..
[root@ZooKeeper-Kafka-01 local]# ln -s kafka_2.12-1.1.0 kafka

2.修改server.properties文件

# master为0
broker.id=0
listeners=PLAINTEXT://ZooKeeper-Kafka-01:9092
advertised.listeners=PLAINTEXT://ZooKeeper-Kafka-01:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
log.dirs=/tmp/kafka-logs
num.partitions=5
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=24
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
# 连接
zookeeper.connect=ZooKeeper-Kafka-01:2181,ZooKeeper-Kafka-02:2181,ZooKeeper-Kafka-03:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
# 可删除topic
delete.topic.enable=true

3.将 kafka_2.12-1.1.0 文件夹复制到另外两个节点下

[root@ZooKeeper-Kafka-01 local]# scp -r kafka_2.12-1.1.0/ 10.200.3.86:/usr/local/
[root@ZooKeeper-Kafka-01 local]# scp -r kafka_2.12-1.1.0/ 10.200.3.87:/usr/local/

并修改每个节点对应的 server.properties 文件的 broker.id和listenrs：

[root@ZooKeeper-Kafka-02 config]# cat server.properties
broker.id=1
listeners=PLAINTEXT://ZooKeeper-Kafka-02:9092
advertised.listeners=PLAINTEXT://ZooKeeper-Kafka-02:9092
 
[root@ZooKeeper-Kafka-03 config]# cat server.properties
broker.id=2
listeners=PLAINTEXT://ZooKeeper-Kafka-03:9092
advertised.listeners=PLAINTEXT://ZooKeeper-Kafka-03:9092

4.启动服务

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

Zookeeper+Kafka集群测试

创建topic：

[root@ZooKeeper-Kafka-01 kafka]# bin/kafka-topics.sh --create --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181 --replication-factor 3 --partitions 3 --topic test

显示topic：

[root@ZooKeeper-Kafka-01 kafka]# bin/kafka-topics.sh --describe --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181 --topic test

列出topic：

[root@ZooKeeper-Kafka-01 kafka]# bin/kafka-topics.sh --list --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181
test

创建 producer(生产者);

# 在master节点上 测试生产消息

[root@ZooKeeper-Kafka-01 kafka]# bin/kafka-console-producer.sh --broker-list ZooKeeper-Kafka-01:9092 -topic test
>hello world
>[2018-04-03 12:18:25,545] INFO Updated PartitionLeaderEpoch. New: {epoch:0, offset:0}, Current: {epoch:-1, offset:-1} for Partition: test-0. Cache now contains 0 entries. (kafka.server.epoch.LeaderEpochFileCache)
this is example ...
>[2018-04-03 12:19:16,342] INFO Updated PartitionLeaderEpoch. New: {epoch:0, offset:0}, Current: {epoch:-1, offset:-1} for Partition: test-2. Cache now contains 0 entries. (kafka.server.epoch.LeaderEpochFileCache)
welcome to china
>[2018-04-03 12:20:53,141] INFO Updated PartitionLeaderEpoch. New: {epoch:0, offset:0}, Current: {epoch:-1, offset:-1} for Partition: test-1. Cache now contains 0 entries. (kafka.server.epoch.LeaderEpochFileCache)

创建 consumer(消费者):

# 在ZooKeeper-Kafka-02节点上 测试消费

[root@ZooKeeper-Kafka-02 kafka]# bin/kafka-console-consumer.sh --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181 -topic test --from-beginning
Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
this is example ...
hello world
[2018-04-03 12:20:53,145] INFO Updated PartitionLeaderEpoch. New: {epoch:0, offset:0}, Current: {epoch:-1, offset:-1} for Partition: test-1. Cache now contains 0 entries. (kafka.server.epoch.LeaderEpochFileCache)
welcome to china

#在ZooKeeper-Kafka-03节点上 测试消费

[root@ZooKeeper-Kafka-03 kafka]# bin/kafka-console-consumer.sh --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181 -topic test --from-beginning
Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
welcome to china
hello world
this is example ...

然后在 producer 里输入消息，consumer 中就会显示出同样的内容，表示消费成功

删除 topic 和关闭服务

[root@ZooKeeper-Kafka-01 kafka]# bin/kafka-topics.sh --delete --zookeeper ZooKeeper-Kafka-01:2181, ZooKeeper-Kafka-02:2181, ZooKeeper-Kafka-03:2181 --topic test

启动服务:

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

停止服务：

bin/kafka-server-stop.sh

至此Zookeeper+Kafka集群配置成功.
