zookeeper:
http://archive.apache.org/dist/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz
kafka地址:
https://archive.apache.org/dist/kafka/0.10.1.1/kafka_2.11-0.10.1.1.tgz
jdk:
1.8版本 可以自己找
1.解压
tar -zxvf zookeeper-3.4.13.tar.gz -C /root
2.创建存放数据日志地址
cd zookeeper-3.4.13 mkdir zkData mkdir zkLogs
3.修改配置文件
cd conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
配置文件修改内容:
dataDir=/root/zookeeper-3.4.13/zkData
dataLogDir=/root/zookeeper-3.4.13/zkLogs
server.1=192.168.9.184:2888:3888
server.2=192.168.9.185:2888:3888
server.3=192.168.9.186:2888:3888
4.添加标识
cd /root/zookeeper-3.4.13/zkData
echo 1 > myid
集群每台服务器添加不一样的id? 184 185 186分别为1 2 3
5.启动
/root/zookeeper-3.4.13/bin/zkServer.sh start
/root/zookeeper-3.4.13/bin/zkServer.sh stop
6.配置快捷命令
vi /etc/profile
#末尾添加
export ZOOKEEPER_HOME=/root/zookeeper-3.4.13
export PATH=$PATH:$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf
?刷新配置
source /etc/profile
7.快捷指令
zkServer.sh start
zkServer.sh stop
1.解压
tar -zxvf kafka_2.12-2.1.1.tgz
2.创建存放数据日志地址
cd kafka_2.12-2.1.1 mkdir Data
3.修改配置文件(注意自己的解压地址)
/root/kafka_2.12-2.1.1/config
vi server.properties
broker.id=1
log.dirs=/root/kafka_2.12-2.1.1/kafka-logs
zookeeper.connect=192.168.9.186:2181,192.168.9.184:2181,192.168.9.185:2181
ps:broker.id? 集群中不能重复
4.启动
/root/kafka_2.12-2.1.1/bin/kafka-server-start.sh /root/kafka_2.12-2.1.1/config/server.properties &
5.配置快捷命令
vi /etc/profile
#末尾添加
export KAFKA_HOME=/root/kafka/kafka_2.12-2.1.1
export PATH=$PATH:$KAFKA_HOME/bin
生效
source /etc/profile
6.重新启动
kafka-server-start.sh /root/kafka_2.12-2.1.1/config/server.properties &
zookeeper常用命令(需配置快捷命令)
zkServer.sh start
zkServer.sh status
zkServer.sh stop
zkServer.sh restart
kafka常用命令(需配置快捷命令)
启动
kafka-topics.sh --bookafka-server-start.sh /root/kafka_2.12-2.1.1/config/server.properties &
查看状态
jps -l
创建topic
kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 3 --topic test
topic 详细分区信息(注意避坑)
kafka-topics.sh --bootstrap-server localhost:9092 --describe
#kafka版本《2.2 查询分区、topic等涉及到zookeeper的命令
# --bootstrap-server 替换--zookeeper
kafka-topics.sh --zookeeper localhost:9092 --describe
#具体topic查看 不加<>
kafka-topics.sh --zookeeper localhost:2181 --describe --topic <topic_name>
topic信息
kafka-topics.sh --zookeeper localhost:2181 --list
查看Kafka Consumer的状态:
kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group
#OR
kafka-consumer-groups.sh --zookeeper localhost:9092 --describe --group
1.
#kafka版本<2.2? 查询分区、topic等涉及到zookeeper的命令?
# --bootstrap-server 替换--zookeeper?
2.启动kafka失败 ,配置没问题情况下
