kafka滚动升级_kafka2升级到3版本

生产环境kafka版本为kafka_2.13-2.8.1.tgz，因存在漏洞需将kafka版本升级至kafka_2.13-3.4.0.tgz以上版本。

升级前验证zookeeper与kafka状态是否正常，使用kafka命令查看当前kafka集群的topic和版本号

/opt/hadoop/coer/kafka_2.13-2.8.1/bin/kafka-topics.sh --bootstrap-server 192.168.10.101:9092 --list

/opt/hadoop/coer/kafka_2.13-2.8.1/bin/kafka-topics.sh -version

在第一台broker上安装kafka_2.13-3.4.0版本的kafka，并启动新版本的kafka

cd /opt/hadoop/core
tar -zxvf kafka_2.13-3.4.0.tar.gz
cp kafka_2.13-2.8.1/config/server.properties   kafka_2.13-3.4.0/config
 
cd kafka_2.13-3.4.0/config
 
vi server.properties
#添加下面这一行配置，这里的版本号，是你的旧版本，不是将要升级的新版本，即是我目前环境的旧版本2.8.1，如果我这里写成我想要升级的新版本3.4.0，那么就会出现最下面的异常报错。
inter.broker.protocol.version=2.8-IV1
 
#关闭kafka_2.13-2.8.1进程
 
cd /opt/hadoop/core/kafka_2.13-2.8.1
bin/kafka-server-stop.sh
 
 
#启动kafka_2.13-3.4.0进程
cd /opt/hadoop/core/kafka_2.13-3.4.0
bin/kafka-server-start.sh -daemon config/server.properties
 
#查看是否能正常访问集群
/opt/hadoop/coer/kafka_2.13-3.4.0/bin/kafka-topics.sh --bootstrap-server --describe --topic topicname
 
#同时可以查看config/server.properties中的配置，查看brokerid
#访问zookeeper查看kafka是否加入集群
zkCli.sh
ls /kafka/broker/ids
 
#查看日志，正常日志应该如下所示：

 逐一对3台kafka进行升级，先停止旧版本的kafka，再启动新版本的kafka，完成滚动升级。
