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：
[[email protected]01 src]# tar -zxvf zookeeper-3.4.10.tar.gz -C /usr/local/ [[email protected]-Kafka-01 src]# cd .. [[email protected]-Kafka-01 local]# ln -s zookeeper-3.4.10 zookeeper [[email protected]-Kafka-01 local]# cd zookeeper/conf/ [[email protected]-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
[[email protected]01 conf]# mkdir /tmp/zookeeper [[email protected]-Kafka-01 conf]# touch /tmp/zookeeper/myid [[email protected]-Kafka-01 conf]# echo 1 > /tmp/zookeeper/myid
3.将zookeeper文件复制到另外两个节点：
[[email protected]01 local]# scp -r zookeeper-3.4.10/ 10.200.3.86:/usr/local/ [[email protected]-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:
[[email protected]02 local]# ln -s zookeeper-3.4.10 zookeeper [[email protected]-Kafka-02 local]# mkdir /tmp/zookeeper [[email protected]-Kafka-02 local]# touch /tmp/zookeeper/myid [[email protected]-Kafka-02 local]# echo 2 > /tmp/zookeeper/myid
#ZooKeeper-Kafka-03节点
[[email protected]03 local]# ln -s zookeeper-3.4.10 zookeeper [[email protected]-Kafka-03 local]# mkdir /tmp/zookeeper [[email protected]-Kafka-03 local]# touch /tmp/zookeeper/myid [[email protected]-Kafka-03 local]# echo 3 > /tmp/zookeeper/myid
5.分别在每个节点上启动 zookeeper测试：
[[email protected]01 zookeeper]# ./bin/zkServer.sh start [[email protected]-Kafka-02 zookeeper]# ./bin/zkServer.sh start [[email protected]-Kafka-03 zookeeper]# ./bin/zkServer.sh start
6.查看状态：
[[email protected]01 zookeeper]# ./bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Mode: follower [[email protected]-Kafka-02 zookeeper]# ./bin/zkServer.sh status ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg Mode: leader [[email protected]-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：
[[email protected]01 src]# tar -zxvf kafka_2.12-1.1.0.tgz -C /usr/local/ [[email protected]-Kafka-01 src]# cd .. [[email protected]-Kafka-01 local]# ln -s kafka_2.12-1.1.0 kafka
2.修改server.properties文件
[[email protected]01 local]# cd kafka/config/ [[email protected]-Kafka-01 config]# vim server.properties # master为0 broker.id=0 # 连接 zookeeper.connect=ZooKeeper-Kafka-01:2181,ZooKeeper-Kafka-02:2181,ZooKeeper-Kafka-03:2181 # 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
[[email protected]01 local]# scp -r kafka_2.12-1.1.0/ 10.200.3.86:/usr/local/ [[email protected]-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：
[[email protected]02 config]# cat server.properties |grep broker.id broker.id=1 [[email protected]-Kafka-03 config]# cat server.properties |grep broker.id broker.id=2
4.启动服务
bin/kafka-server-start.sh config/server.properties &
Zookeeper+Kafka集群测试
创建topic：
[[email protected]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：
[[email protected]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：
[[email protected]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
[[email protected]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
[[email protected]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
[[email protected]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
[[email protected]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.
