参考文章：kafka学习笔记十kafka-SSL安全认证机制_hwhanwan的专栏-CSDN博客_kafka ssl认证
一、生成配置cert
1.1生成 server keystore
keytool -keystore server.keystore.jks -alias kafka-server -validity 365 -keyalg RSA -genkey
#注:在生成 server.keystore.jks 时，-alias需要指定为 localhost,此处是表示的主机的host,而且根本不需要生成client.keystore.jks文件
keytool -keystore server.keystore.jks -alias localhost -validity 365 -keyalg RSA -genkey
[root@iZbp19pf0xgaj0oo0041u6Z cert]# keytool -keystore server.keystore.jks -alias kafka-server -validity 365 -keyalg RSA -genkey
Enter keystore password:
