[AWS]MKS调用报错：WARN Session 0x0 for server z-2.sconceptmqprd.y5xuv6.c1.kafka.me-central-1.amazonaws.co-优快云博客

背景，公司使用了AWS 的MSK，在命令行连接配置的时候，报错：
报错1:

以上的报错都是因为MSK的连接真的很麻烦。不能通过Apache ZooKeeper 的方式连接。其次要保证跳板机和MSK在一个VPC中。

解决方式：
1.登录跳板机，下载kafka命令

#wget https://archive.apache.org/dist/kafka/{YOUR MSK VERSION}/kafka_2.13-{YOUR MSK VERSION}.tgz
#我的3.5.1的版本
wget https://archive.apache.org/dist/kafka/3.5.1/kafka_2.13-3.5.1.tgz
#下载慢的，可以在本地电脑下载之后，再上传到服务器。
tar -xzf kafka_2.13-3.5.1.tgz

2.必做，下载 Amazon MSK IAM JAR 文件
java要用，这里要保证java-11以上的版本

cd kafka_2.13-3.5.1/libs
wget https://github.com/aws/aws-msk-iam-auth/releases/download/v1.1.1/aws-msk-iam-auth-1.1.1-all.jar

3.编辑验证方式的文件，必须，不然必定出现报错：

vim kafka_2.13-3.5.1/bin/client.properties 
security.protocol=SASL_SSL
sasl.mechanism=AWS_MSK_IAM
sasl.jaas.config=software.amazon.msk.auth.iam.IAMLoginModule required;
sasl.client.callback.handler.class=software.amazon.msk.auth.iam.IAMClientCallbackHandler

4.尝试连接，创建topic：

.kafka-topics.sh --create --bootstrap-server BootstrapServerString --command-config client.properties --replication-factor 3 --partitions 1 --topic MSKTutorialTopic

#BootstrapServerString为端点地址
