kafak权限管理

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，centos13zoopeeker 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

¢os11
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/[email protected]

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
