参考连接

1.下载需要的安装包

wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
wget http://mirrors.shu.edu.cn/apache/kafka/1.1.0/kafka_2.11-1.1.0.tgz

http://kafka.apache.org/downloads

以前的版本在下面下载

 

 2.准备 zookeeper目录 三个节点192.168.120.81 192.168.120.82 192.168.120.83

mkdir /opt/zookeeper
mkdir /opt/zookeeper/zkdata
mkdir /opt/zookeeper/zkdatalog
cp /root/zookeeper-3.4.10.tar.gz /opt/
cd /opt/
tar -zxvf zookeeper-3.4.10.tar.gz -C /opt/zookeeper
cp /opt/zookeeper/zookeeper-3.4.10/conf/zoo_sample.cfg /opt/zookeeper/zookeeper-3.4.10/conf/zoo.cfg #备份配置文件

vi /opt/zookeeper/zookeeper-3.4.10/conf/zoo.cfg   # 这样查看的配置 cat /opt/zookeeper/zookeeper-3.4.10/conf/zoo.cfg | egrep -v "^$|^#"

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/zkdata
dataLogDir=/opt/zookeeper/zkdatalog
clientPort=2181
server.1=192.168.120.81:2888:3888
server.2=192.168.120.82:2888:3888
server.3=192.168.120.83:2888:3888

#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
#192.168.120.83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-3.4.10/bin/zkServer.sh /opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh.bak

vi /opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh

ZOO_LOG_DIR="$($GREP "^[[:space:]]*dataLogDir" "$ZOOCFG" | sed -e 's/.*=//')"  #125添加这一行

3.拷贝配置好的文件到其他主机

scp -r /opt/zookeeper 192.168.120.82:/opt/
scp -r /opt/zookeeper 192.168.120.83:/opt/

#server1
echo "1" > /opt/zookeeper/zkdata/myid
#server2
echo "2" > /opt/zookeeper/zkdata/myid
#server3
echo "3" > /opt/zookeeper/zkdata/myid

 

/opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start #启动服务
/opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh status #查看状态

 

kafa集群目录准备

mkdir /opt/kafka

mkdir /opt/kafka/kafkalogs

cd /opt/kafka
wget http://mirrors.shu.edu.cn/apache/kafka/1.1.0/kafka_2.11-1.1.0.tgz
tar -zxvf kafka_2.11-1.1.0.tgz

vi /opt/kafka/kafka_2.11-1.1.0/config/server.properties

listeners=PLAINTEXT://192.168.120.81:9092
log.dirs=/opt/kafka/kafkalogs/
zookeeper.connect=192.168.120.81:2181,192.168.120.82:2181,192.168.120.83:2181

 

[root@81server ~]# cat /opt/kafka/kafka_2.11-1.1.0/config/server.properties | egrep -v "^$|^#"  #查看所有参数

zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0

拷贝配置好的文件和程序

scp -r /opt/kafka 192.168.120.82:/opt/
scp -r /opt/kafka 192.168.120.83:/opt/

其他节点只修改两次
vi /opt/kafka/kafka_2.11-1.1.0/config/server.properties

broker.id=1 #此处不能重复
......
listeners=PLAINTEXT://192.168.120.82:9092

运行kafka服务在三个节点

nohup /opt/kafka/kafka_2.11-1.1.0/bin/kafka-server-start.sh /opt/kafka/kafka_2.11-1.1.0/config/server.properties >/dev/null 2>&1 &

 

随便在其中一台节点主机执行

/opt/kafka/kafka_2.11-1.1.0/bin/kafka-topics.sh --create --zookeeper 192.168.120.81:2181,192.168.120.82:2181,192.168.120.83:2181 --replication-factor 1 --partitions 1 --topic test

/opt/kafka/kafka_2.11-1.1.0/bin/kafka-topics.sh --list --zookeeper 192.168.120.81:2181,192.168.120.82:2181,192.168.120.83:2181 #查看刚才的信息

查看topic状态

/opt/kafka/kafka_2.11-1.1.0/bin/kafka-topics.sh --describe --zookeeper 192.168.120.81:2181,192.168.120.82:2181,192.168.120.83:2181 --topic test

 kafka内容查询

/opt/kafka/kafka_2.11-1.1.0/bin/kafka-consumer-groups.sh --bootstrap-server \
192.168.1.151:9092,192.168.1.152:9092,192.168.1.153:9092 --list groupid

/opt/kafka/kafka_2.11-1.1.0/bin/kafka-consumer-groups.sh --bootstrap-server \
192.168.1.151:9092,192.168.1.152:9092,192.168.1.153:9092 --group orderdy030_refund --describe

 

 

vi zookeeper.sh

/opt/zookeeper/zookeeper-3.4.10/bin/zkServer.sh start

vi kafka.sh

nohup /opt/kafka/kafka_2.11-1.1.0/bin/kafka-server-start.sh /opt/kafka/kafka_2.11-1.1.0/config/server.properties >/dev/null 2>&1 &
