kafka集群环境搭建
1、初始化环境准备
安装jdk，安装zookeeper并保证zk服务正常启动
2、下载安装包并上传解压
通过以下地址进行下载安装包
node01执行以下命令，下载并解压
cd /export/softwares
wget http://archive.apache.org/dist/kafka/1.0.0/kafka_2.11-1.0.0.tgz
tar –zxvf kafka_2.11-1.0.0.tgz -C /export/servers/3、node01服务器修改kafka配置文件
node01执行以下命令进入到kafka的配置文件目录，修改配置文件
node01执行以下命令创建数据文件存放目录
mkdir -p /export/servers/kafka_2.11-1.0.0/logs
cd /export/servers/kafka_2.11-1.0.0/config
vim server.properties
broker.id=0
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=/export/servers/kafka_2.11-1.0.0/logs
num.partitions=2
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.flush.interval.messages=10000
log.flush.interval.ms=1000
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=node01:2181,node02:2181,node03:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
delete.topic.enable=true
host.name=node014、安装包分发到其他服务器上面去
node01执行以下命令，将node01服务器的kafka安装包发送到node02和node03服务器上面去
cd /export/servers/
scp -r kafka_2.11-1.0.0/ node02:$PWD
scp -r kafka_2.11-1.0.0/ node03:$PWD5、node02与node03服务器修改配置文件
node02与node03服务器修改kafka配置文件
node02使用以下命令修改kafka配置文件
cd /export/servers/kafka_2.11-1.0.0/config
vim server.propertiesbroker.id=1
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=/export/servers/kafka_2.11-1.0.0/logs
num.partitions=2
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.flush.interval.messages=10000
log.flush.interval.ms=1000
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=node01:2181,node02:2181,node03:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
delete.topic.enable=true
host.name=node02
node03使用以下命令修改kafka配置文件
cd /export/servers/kafka_2.11-1.0.0/config
vim server.propertiesbroker.id=2
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=/export/servers/kafka_2.11-1.0.0/logs
num.partitions=2
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.flush.interval.messages=10000
log.flush.interval.ms=1000
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=node01:2181,node02:2181,node03:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
delete.topic.enable=true
host.name=node03
6、kafka集群启动与停止
注意事项：在kafka启动前，一定要让zookeeper启动起来。
node01执行以下命令将kafka进程启动在后台
cd /export/servers/kafka_2.11-1.0.0
nohup bin/kafka-server-start.sh config/server.properties 2>&1 &node02执行以下命令将kafka进程启动在后台
cd /export/servers/kafka_2.11-1.0.0
nohup bin/kafka-server-start.sh config/server.properties 2>&1 &node03执行以下命令将kafka进程启动在后台
cd /export/servers/kafka_2.11-1.0.0
nohup bin/kafka-server-start.sh config/server.properties 2>&1 &三台机器也可以执行以下命令停止kafka集群
cd /export/servers/kafka_2.11-1.0.0
bin/kafka-server-stop.sh7、kafka集群的一键启动与关闭
在kafka的bin目录下添加kf.sh
cd cd /export/servers/kafka_2.11-1.0.0/bin
vim kf.sh
#!/bin/bash
case $1 in
"start"){
for i in node01 node02 node03
do
echo "*******$i*******"
ssh $i "source /etc/profile;/export/servers/kafka_2.11-1.0.0/bin/kafka-server-start.sh -daemon /export/servers/kafka_2.11-1.0.0/config/server.properties"
done
};;
"stop"){
for i in node01 node02 node03
do
echo "*******$i*******"
ssh $i "source /etc/profile;/export/servers/kafka_2.11-1.0.0/bin/kafka-server-stop.sh"
done
};;
esac修改文件权限
chmod 751 kf.sh
kafka集群启动：
cd /export/servers/kafka_2.11-1.0.0
bin/kf.sh startkafka集群关闭：
cd /export/servers/kafka_2.11-1.0.0
bin/kf.sh stop
