kafka 0.10 集群部署

预备工作：

3台机器分别编辑/etc/hosts文件，添加主机名映射
10.1.2.17 master
10.1.2.22 slave01
10.1.7.12 slave02

配置免密登陆

ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.1.2.17
ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.1.2.22
ssh-copy-id -i ~/.ssh/id_rsa.pub root@10.1.7.12

安装jdk

安装zookeeper

解压安装包
tar -zxvf zookeeper-3.4.10.tar.gz -C /data

/data/zookeeper-3.4.10/conf文件下重命名文件
mv zoo_sample.cfg zoo.cfg

编辑zoo.cfg文件
dataDir=/data/zookeeper-3.4.10/data
clientPort=12181
server.0=master:2888:3888
server.1=slave01:2888:3888
server.2=slave02:2888:3888

创建data目录
mkdir /data/zookeeper-3.4.10/data

/data/zookeeper-3.4.10/data目录下添加myid文件
echo 0 > myid

分发zookeeper文件夹到另外2个节点
scp -r /data/zookeeper-3.4.10 slave01:/data
scp -r /data/zookeeper-3.4.10 slave02:/data

在另外2个节点下分别修改myid文件中的值
slave01：
echo 1 > myid
slave02:
echo 2 > myid

编写zookeeper操作脚本：
vi zk.sh

#!/bin/bashfor host in master slave01 slave02do    echo "$host $1......"    ssh $host "source /etc/profile;/data/zookeeper-3.4.10/bin/zkServer.sh $1" ## 参数为start/stop/statusdone

./zk.sh start 启动zookeeper集群
./zk.sh stop 关闭zookeeper集群
./zk.sh status 查看zookeeper集群状态

安装kafka

解压kafka压缩包

tar -zxvf kafka_2.10-0.10.0.1.tgz -C /data/

编辑配置文件server.properties

/data/kafka_2.10-0.10.0.1/config/server.propertiesbroker.id=0listeners=PLAINTEXT://master:19092log.dirs=/data/kafka-logszookeeper.connect=master:12181,slave01:12181,slave02:12181

kafka文件夹分发到另外2个节点

scp -r /data/kafka_2.10-0.10.0.1 slave01:/datascp -r /data/kafka_2.10-0.10.0.1 slave02:/data

修改另外2个节点下的server.properties文件
slave01:
broker.id=1
listeners=PLAINTEXT://slave01:19092

slave02:
broker.id=2
listeners=PLAINTEXT://slave02:19092

编写kafka操作脚本
vi kafka.sh

#!/bin/bashsource /etc/profileif [ $1 = "start" ]then    echo "------------ensure that zookeeper is started------------------"    cat /data/kafka_2.10-0.10.0.1/config/nodes | while read host    do    {        echo "$host is starting..."        ssh $host "source /etc/profile;nohup /data/kafka_2.10-0.10.0.1/bin/kafka-server-start.sh /data/kafka_2.10-0.10.0.1/config/server.properties >/dev/null 2>&1 &"    }&    wait    done    elif [ $1 = "stop" ]then    cat /data/kafka_2.10-0.10.0.1/config/nodes | while read host    do    {        echo "$host is stoping..."        ssh $host "source /etc/profile;nohup /data/kafka_2.10-0.10.0.1/bin/kafka-server-stop.sh /data/kafka_2.10-0.10.0.1/config/server.properties >/dev/null 2>&1 &"    }&    wait    doneelif [ $1 = "producer" ]then    kafka-console-producer.sh --broker-list master:19092,slave01:19092,slave02:19092 --topic $2 # 启动生产者，$2是topicelif [ $1 = "consumer" ]then    kafka-console-consumer.sh --zookeeper localhost:12181 --from-beginning --topic $2 #启动消费topicelif [ $1 = "delete" ]then    kafka-topics.sh --delete --zookeeper localhost:12181 --topic $2 #删除topicelif [ $1 = "create" ]then    kafka-topics.sh --create --zookeeper localhost:12181 --replication-factor 1 --partitions 3 --topic $2 #创建topicelif [ $1 = "list" ]then    kafka-topics.sh --list --zookeeper localhost:12181 #查看topicelse    echo "parameter invalid"fi

脚本运行要求有nodes文件
vi /data/kafka_2.10-0.10.0.1/config/nodes
10.1.2.17
10.1.2.22
10.1.7.12

启动kafka之前先启动zookeeper

./kafka.sh start 启动kafka集群
./kafka.sh stop 停止kafka集群
./kafka.sh list 查看所有topic列表
./kafka.sh create [topic_name] 创建topic
./kafka.sh producer [topic_name] 给topic生产消息
./kafka.sh consumer [topic_name] 给topic消费消息
