kafka 学习（四）安装部署

kafka集群安装部署到使用

由于条件有限整了三台虚拟机进行部署

主机规划：

10.250.23.213 ZooKeeper-Kafka-01
10.250.23.214 ZooKeeper-Kafka-02
10.250.23.215 ZooKeeper-Kafka-03

一段小插曲：虚拟机网络不通：

1、设置网络为桥接模式

2、修改配置文件内容/etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
BOOTPROTO=static
NAME=ens33
DEVICE=ens33
ONBOOT=yes
GATEWAY=10.250.23.254
IPADDR=10.250.23.213
DNS1=8.8.8.8
NETMASK=255.255.255.0

3、关掉防火墙

4、更新yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache
yum -y update

言归正传，软件下载地址：

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.5.4-beta/zookeeper-3.5.4-beta.tar.gz
wget http://mirror.bit.edu.cn/apache/kafka/2.2.0/kafka_2.12-2.2.0.tgz

三台主机hosts文件一致：

vim /etc/hosts
10.250.23.213 ZooKeeper-Kafka-01 
10.250.23.214 ZooKeeper-Kafka-02
10.250.23.215 ZooKeeper-Kafka-03

一、安装zookeeper

1.在master节点上操作：

[root@ZooKeeper-Kafka-01 src]# tar -zxvf zookeeper-3.5.4-beta.tar.gz -C /usr/local/
[root@ZooKeeper-Kafka-01 src]# cd ..
[root@ZooKeeper-Kafka-01 local]# ln -s zookeeper-3.5.4-beta 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=10.250.23.213-01:2888:3888
server.2=10.250.23.214-02:2888:3888
server.3=10.250.23.215-03:2888:3888

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-3.5.4-beta/ 10.250.23.214:/usr/local/
[root@ZooKeeper-Kafka-01 local]# scp -r zookeeper-3.5.4-beta/ 10.250.23.215:/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-3.5.4-beta 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-3.5.4-beta 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！！！

二、Kafka集群安装配置

1.安装：

[root@ZooKeeper-Kafka-01 src]# tar -zxvf kafka_2.12-2.2.0.tgz -C /usr/local/
[root@ZooKeeper-Kafka-01 src]# cd ..
[root@ZooKeeper-Kafka-01 local]# ln -s kafka_2.12-2.2.0 kafka

2.修改server.properties文件

# master为0
broker.id=0
listeners=PLAINTEXT://10.250.23.213:9092
advertised.listeners=PLAINTEXT://10.250.23.213:9092
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=10.250.23.213:2181,10.250.23.214:2181,10.250.23.215:2181
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_2.12-2.2.0/ 10.250.23.214:/usr/local/
[root@ZooKeeper-Kafka-01 local]# scp -r kafka_2.12-2.2.0/ 10.250.23.215:/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://10.250.23.214:9092
advertised.listeners=PLAINTEXT://10.250.23.214:9092

[root@ZooKeeper-Kafka-03 config]# cat server.properties
broker.id=2
listeners=PLAINTEXT://10.250.23.215:9092
advertised.listeners=PLAINTEXT://10.250.23.215:9092

4.启动三台服务器（三台的操作一样）

./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 10.250.23.213:2181, 10.250.23.214:2181, 10.250.23.215:2181 
--replication-factor 3 --partitions 3 --topic test

显示topic：

[root@ZooKeeper-Kafka-01 kafka]# ./bin/kafka-topics.sh --describe --zookeeper 10.250.23.213:2181, 10.250.23.214:2181, 10.250.23.215:2181 --topic test

列出topic：

[root@ZooKeeper-Kafka-01 kafka]# ./bin/kafka-topics.sh --list --zookeeper 10.250.23.213:2181, 10.250.23.214:2181, 10.250.23.215:2181 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 10.250.23.213:9092 -topic test 
>hello world

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 --bootstrap-server 10.250.23.213:9092, 10.250.23.214:9092, 10.250.23.215:9092
-topic test --from-beginning

#在ZooKeeper-Kafka-03节点上测试消费

[root@ZooKeeper-Kafka-03 kafka]# ./bin/kafka-console-consumer.sh --bootstrap-server 10.250.23.213:9092, 10.250.23.214:9092, 10.250.23.215:9092
-topic test --from-beginning

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 10.250.23.213:2181, 10.250.23.214:2181, 10.250.23.215:2181 --topic test

至此Zookeeper+Kafka集群配置成功.
