kafka权限认证

背景：
最近公司因为用的云服务器，需要保证kafka的安全性。可喜的是kafka0.9开始，已经支持权限控制了。网上中文资料又少，特此基于kafka0.9，记录kafaka的权限控制 ( flume需要1.7及其以上才支持kafka的SSL认证)。

下面各位看官跟着小二一起开始kafak权限认证之旅吧！嘎嘎嘎！

介绍：
kafka权限控制整体可以分为三种类型：
1.基于SSL(CDH 5.8不支持)
2.基于Kerberos(此认证一般基于CDH，本文不与讨论)
3.基于acl的 (CDH5.8中的kafka2.X不支持 )

本文主要基于apace版本的，实现1和3，也是用的最多的展开讨论。

统一说明：
在本文中&符号表示注释

一，准备工作
组件分布
kafka centos11，centos12，centos13
zoopeeker centos11，centos12，centos13

二、在kafka集群任选一台机子 ( 先介绍基于SSL的 )

密码统一为123456

&Step 1  Generate SSL key and certificate for each Kafka broker
keytool -keystore server.keystore.jks -alias centos11 -validity 365 -genkey

%Step 2  Creating your own CA
openssl req -new -x509 -keyout ca-key -out ca-cert -days 365
keytool -keystore server.truststore.jks -alias CARoot -import -file ca-cert
keytool -keystore client.truststore.jks -alias CARoot -import -file ca-cert

&Step 3  Signing the certificate
keytool -keystore server.keystore.jks -alias centos11 -certreq -file cert-file
openssl x509 -req -CA ca-cert -CAkey ca-key -in cert-file -out cert-signed -days 365 -CAcreateserial -passin pass:123456
keytool -keystore server.keystore.jks -alias CARoot -import -file ca-cert
keytool -keystore server.keystore.jks -alias centos11 -import -file cert-signed

三、其他的kafka集群

 &机器centos13  centos12
 keytool -keystore kafka.client.keystore.jks -alias centos13 -validity 365 -genkey 
  keytool -keystore kafka.client.keystore.jks -alias centos13 -certreq -file cert-file
  cp cert-file cert-file-centos13

 &centos11
 scp ./ca* ce* server* root@centos13:/opt/kafka_2.10/

  openssl x509 -req -CA ca-cert -CAkey ca-key -in cert-file-centos13  -out cert-signed-centos13  -days 365 -CAcreateserial -passin pass:123456 
 keytool -keystore kafkacentos13.client.keystore.jks -alias CARoot -import -file ca-cert 
 keytool -keystore kafkacentos13.client.keystore.jks -alias centos13 -import -file cert-signed-centos13 



rm -rf producer.properties
echo "bootstrap.servers=centos13:9093" >> producer.properties  
echo "security.protocol=SSL" >> producer.properties  
echo "ssl.truststore.location=/opt/kafka_2.10/kafkacentos12.client.keystore.jks">> producer.properties  
echo "ssl.truststore.password=123456">> producer.properties  
echo "ssl.keystore.location=/opt/kafka_2.10/server.keystore.jks">> producer.properties  
echo "ssl.keystore.password=123456">> producer.properties  
echo "ssl.key.password=123456">> producer.properties   

4.验证：

openssl s_client -debug -connect localhost:9093 -tls1

output:
    -----BEGIN CERTIFICATE-----
        {variable sized random bytes}
        -----END CERTIFICATE-----
        subject=/C=US/ST=CA/L=Santa Clara/O=org/OU=org/CN=Sriharsha Chintalapani
        issuer=/C=US/ST=CA/L=Santa Clara/O=org/OU=org/CN=kafka/emailAddress=test@test.com

5.使用：

bin/kafka-console-consumer.sh --bootstrap-server kafka2:9093 --topic test --new-consumer --consumer.config  config/producer.properties

bin/kafka-console-producer.sh --broker-list centos11:9093 --topic test --producer.config  ./config/producer.properties  

bin/kafka-console-consumer.sh --bootstrap-server centos11:9093 --topic test --new-consumer --consumer.config ./config/producer.properties 

bin/kafka-console-consumer.sh --bootstrap-server centos13:9093 --topic test --new-consumer --consumer.config ./config/producer.properties  --from-beginning

6.基于ACL

server.properties中加配置

allow.everyone.if.no.acl.found=true
super.users=User:root
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer  
principal.builder.class=org.apache.kafka.common.security.auth.DefaultPrincipalBuilder 

7.ACL的简单使用：

bin/kafka-acls.sh --authorizer-properties zookeeper.connect=centos11:2181 --add --allow-principal User:Bob --allow-principal User:Alice --allow-host 198.51.100.0 --allow-host 198.51.100.1 --operation Read --operation Write --topic test

bin/kafka-acls.sh --authorizer-properties zookeeper.connect=centos11:2181 --remove --allow-principal User:Bob --allow-principal User:Alice --allow-host 198.51.100.0 --allow-host 198.51.100.1 --operation Read --operation Write --topic test

8.Java Demo
需要将server.keystore.jks、client.truststore.jks从任一台机器上拷贝下来即可。

SSL is supported only for the new Kafka Producer and Consumer, the older API is not supported
