zookeeper部署kafka集群

1.准备工作:

iptables -F      #关闭防火墙

systemctl stop firewalld.service #关闭防火墙

准备三台虚拟机并放入/etc/hosts下

192.168.100.242    testceph

192.168.100.244    redis1

192.168.100.245    redis2

将testceph的/etc/hosts文件拷贝到其他两台虚拟机上

命令:

[root@testceph ~]# for i in 244 245
> do
> scp /etc/hosts  192.168.100.$i:/etc/
> done
root@192.168.100.244's password:  输入密码
hosts                                                                                         100%  238   231.1KB/s   00:00    
root@192.168.100.245's password:  输入密码
hosts                                                                                         100%  238   418.2KB/s   00:00   

2.安装依赖包

[root@testceph ~]yum install -y gcc g++ make gcc-c++ kernel-devel automake autoconf libtool make wget tcl vim  unzip git java

3.准备 zookeeper目录 三个节点 192.168.100.242   192.168.100.244  192.168.100.245 (三台都要操作)

命令:mkdir /opt/zookeeper

           mkdir /opt/zookeeper/zkdata

           mkdir /opt/zookeeper/zkdatalog

 

zookeeper安装路径:wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz

 

 

命令:cp /root/zookeeper-3.4.14.tar.gz /opt/

命令:cd /opt

命令:tar -zxvf zookeeper-3.4.14.tar.gz -C /opt/zookeeper

命令:cp /opt/zookeeper/zookeeper-3.4.14/conf/zoo_sample.cfg /opt/zookeeper/zookeeper-3.4.14/conf/zoo.cfg     #备份配置文件

4.修改zookeeper配置文件

命令:vim /opt/zookeeper/zookeeper-3.4.14/conf/zoo.cfg     # 这样查看的配置 cat /opt/zookeeper/zookeeper-3.4.14/conf/zoo.cfg | egrep -v "^$|^#"

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/zkdata
dataLogDir=/opt/zookeeper/zkdatalog
clientPort=2181
server.1=192.168.100.242:2888:3888
server.2=192.168.100.244:2888:3888
server.3=192.168.100.245:2888:3888

(注意:前面不能有空格)

 

 

 注意:server.1 这个1是服务器的标识也可以是其他的数字, 表示这个是第几号服务器,用来标识服务器,这个标识要写到快照目 录下面myid文件里
           192.168.100.245为集群里的IP地址,第一个端口是master和slave之间的通信端口,默认是2888,第二个端口是leader选举的 端口,集群刚启动的时候选举或者leader挂掉之后进行新的选举的端口默认是3888

 

注意
如果指定了日志位置需要修改下面参数
cp /opt/zookeeper/zookeeper-3.4.14/bin/zkServer.sh /opt/zookeeper/zookeeper-3.4.14/bin/zkServer.sh.bak

命令:vim /opt/zookeeper/zookeeper-3.4.14/bin/zkServer.sh

ZOO_LOG_DIR="$($GREP "^[[:space:]]*dataLogDir" "$ZOOCFG" | sed -e 's/.*=//')"  #124添加这一行

 

 

 

5.拷贝配置好的文件到其他主机

命令:scp -r /opt/zookeeper 192.168.100.244:/opt/

命令:scp -r /opt/zookeeper 192.168.100.245:/opt/

创建快照目录myid文件

#server.1

echo "1" > /opt/zookeeper/zkdata/myid

#server.2

echo "2" > /opt/zookeeper/zkdata/myid

#server.3

echo "3" > /opt/zookeeper/zkdata/myid

6.启动服务

命令:/opt/zookeeper/zookeeper-3.4.14/bin/zkServer.sh start    

命令:/opt/zookeeper/zookeeper-3.4.14/bin/zkServer.sh status      #查看状态

注意:当看见有一台Mode:leader(管理节点)    两台Mode:follower(节点)即为成功

 

以上就是zookeeper配置完成,接下来配置kafka

 

1.kafka集群目录准备

命令:mkdir /opt/kafka

命令:mkdir /opt/kafka/kafkalogs

命令:cd /opt/kafka

命令:wget http://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.3.1/kafka_2.12-2.3.1.tgz        #安装包路径

命令:tar -zvxf kafka_2.12-2.3.1.tgz          #解包

 

2.修改配置文件

有三处需要修改

listeners=PLAINTEXT://192.168.100.242:9092          #开启PLAINTEXT认证(用户名和密码认证)确保9092端口能够连接

log.dirs=/opt/kafka/kafkalogs/                                    #指定kafka日志路径

zookeeper.connect=192.168.100.242:2181,192.168.100.244:2181,192.168.100.245:2181         #指定zookeeper集群路径

[root@testceph kafka]# cat /opt/kafka/kafka_2.12-2.3.1/config/server.properties | egrep -v "^$|^#"      #查看所有参数
broker.id=0
listeners=PLAINTEXT://192.168.100.242:9092
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=/opt/kafka/kafkalogs/
num.partitions=1
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=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=192.168.100.242:2181,192.168.100.244:2181,192.168.100.245:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0

 

3.拷贝配置好的文件和程序

命令:scp -r /opt/kafka 192.168.100.244:/opt/

命令:scp -r /opt/kafka 192.168.100.245:/opt/

 

4.其他节点只需修改两处

broker.id=1             #节点id号不能一样

listeners=PLAINTEXT://192.168.100.244:9092      #认证的IP号和自己的主机IP一致

 

5.运行kafka服务在三个节点

命令:nohup /opt/kafka/kafka_2.12-2.3.1/bin/kafka-server-start.sh /opt/kafka/kafka_2.12-2.3.1/config/server.properties >/dev/null 2>&1 &

 

 

6.随便在其中一台节点主机执行

命令:/opt/kafka/kafka_2.12-2.3.1/bin/kafka-topics.sh --create --zookeeper 192.168.100.242:2181,192.168.100.244:2181,192.168.100.245:2181 --replication-factor 1 --partitions 1 --topic test

#通过zookeeper集群创建topics名字test(消息主题:相当于文件系统目录,用于保存消息内容)

 

 命令:/opt/kafka/kafka_2.12-2.3.1/bin/kafka-topics.sh --list --zookeeper 192.168.100.242:2181,192.168.100.244:2181,192.168.100.245:2181

#通过zookeeper集群来查看topics列表(只有刚才创建的test)

 

 

7.查看topic状态

命令:/opt/kafka/kafka_2.12-2.3.1/bin/kafka-topics.sh --describe --zookeeper 192.168.100.242:2181,192.168.100.244:2181,192.168.100.245:2181 --topic test

#通过zookeeper集群查看topic状态

 

有什么做得不对的指正一下,在下不胜感激

 

知识扩展:

1.如果kafka已经输入过内容,查看内容的命令就是

命令:/opt/kafka/kafka_2.12-2.3.1/bin/kafka-consumer-groups.sh --bootstrap-server 192.168.100.242:9092,192.168.100.244:9092,192.168.100.245:9092 --list groupid

#通过zookeeper集群来查看列表组ID

2.查看具体的消费者group的详情信息,需要给出group的名称

命令:/opt/kafka/kafka_2.12-2.3.1/bin/kafka-consumer-groups.sh --bootstrap-server 192.168.100.242:9092,192.168.100.244:9092,192.168.100.245:9092 --group orderdy030_refund --describe

总结:。。。。。。。。。。。(此处省略一万字)
