kafka开启kerberos

一、基本环境准备

创建票据创建Kerberos主体（Principal）：

使用kadmin.local或kadmin命令为Zookeeper和Kafka服务创建Kerberos主体。例如：

注意有几台机器创建几个

kadmin.local -q "addprinc -randkey zookeeper/[email protected]"

kadmin.local -q "addprinc -randkey kafka/[email protected]"

验证主体是否创建成功

kadmin.local -q "listprincs"

root@dshieldcdh02 \~\]# kadmin.local -q "listprincs" Authenticating as principal root/[email protected] with password. K/[email protected] host/[email protected] host/[email protected] kadmin/[email protected] kadmin/[email protected] kadmin/[email protected] kafka/[email protected] kafka/[email protected] kafka/[email protected] kiprop/[email protected] krbtgt/[email protected] root/[email protected] zookeeper/[email protected] zookeeper/[email protected] [zookeeper/[email protected]](mailto:zookeeper/[email protected]) 1. 创建keytab mkdir /etc/security/keytabs/ kadmin.local -q "xst -k /etc/security/keytabs/kafka.keytab [kafka/[email protected]](mailto:kafka/[email protected])" kadmin.local -q "xst -k /etc/security/keytabs/kafka.keytab [kafka/[email protected]](mailto:kafka/[email protected])" kadmin.local -q "xst -k /etc/security/keytabs/kafka.keytab [kafka/[email protected]](mailto:kafka/[email protected])" 1. 验证KeyTab文件内容： klist -kt /etc/security/keytabs/zookeeper.keytab klist -kt /etc/security/keytabs/kafka.keytab kinit -kt /etc/security/keytabs/zookeeper.keytab [zookeeper/[email protected]](mailto:zookeeper/[email protected]) 1. 将keytab文件拷贝到其他两天zookeeper上,需要将keytab文件拷贝过去才可以使用 scp /etc/security/keytabs/\*keytab root@dshieldcdh01:/etc/security/keytabs/ scp /etc/security/keytabs/\*keytab root@dshieldcdh03:/etc/security/keytabs/ 1. 在其他机器上验证keytab文件可用 kinit -kt /etc/security/keytabs/zookeeper.keytab [zookeeper/[email protected]](mailto:zookeeper/[email protected]) 二、Zookeeper配置Kerberos 1. 配置Zookeeper的JAAS文件： 在Zookeeper的配置目录下创建JAAS配置文件（如zookeeper_jaas.conf），内容如下： java Server { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true keyTab="/etc/security/keytabs/zookeeper.keytab" principal="zookeeper/[email protected]" useTicketCache=false; }; Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true keyTab="/etc/security/keytabs/zookeeper.keytab" principal="zookeeper/[email protected]" useTicketCache=false; }; 注意修改principal和keyTab路径以匹配实际环境。 在Zookeeper的启动脚本中添加JVM参数，指定JAAS配置文件的路径。 配置zookeeper的kerberos验证，切换到配置文件目录下cd conf，添加zoo.cfg配置文件，cp zoo_sample.cfg zoo.cfg打开zoo.cfg配置文件，添加配置，修改Zookeeper的配置文件cat zoo.cfg 启用SASL认证，并指定认证提供者。 authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider jaasLoginRenew=3600000 kerberos.removeHostFromPrincipal=true kerberos.removeRealmFromPrincipal=true export JVMFLAGS="-Djava.security.auth.login.config= /usr/local/apache-zookeeper-3.6.4/conf/zookeeper_jaas.conf" scp /usr/local/apache-zookeeper-3.6.4/conf/zookeeper_jaas.conf root@dshieldcdh02:/usr/local/apache-zookeeper-3.6.4/conf scp /usr/local/apache-zookeeper-3.6.4/conf/zookeeper_jaas.conf [root@dshieldcdh03:/usr/local/apache-zookeeper-3.6.4/conf](mailto:root@dshieldcdh03:/usr/local/apache-zookeeper-3.6.4/conf) \[root@dshieldcdh03 \~\]# cat /usr/local/apache-zookeeper-3.6.4/conf/zookeeper_jaas.conf Server { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true useTicketCache=false keyTab="/etc/security/keytabs/zookeeper.keytab" principal="zookeeper/[email protected]"; }; cat /usr/local/apache-zookeeper-3.6.4/conf/zookeeper_client_jaas.conf Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true useTicketCache=false keyTab="/usr/local/apacje-zookeeper-3.6.4/conf/zk.service.keytab" principal="zookeeper/[email protected]"; }; 三、Kafka配置Kerberos 将kafka用户的keytab文件拷贝到其他服务器上 scp /etc/security/keytabs/kafka.keytab root@ dshieldcdh02:/etc/security/keytabs/kafka.keytab 配置Kafka的JAAS文件： 在Kafka的配置目录下创建JAAS配置文件（如kafka_client_jaas.conf），内容如下： kafka_client_jaas.conf KafkaServer { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; KafkaClient { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/zookeeper.keytab" storeKey=true useTicketCache=false serviceName="zookeeper" principal=" zookeeper/[email protected]"; }; com.sun.security.jgss.krb5.initiate { com.sun.security.auth.module.Krb5LoginModule required renewTGT=false doNotPrompt=true useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; kafka_server_jaas.conf KafkaServer { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; KafkaClient { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="/etc/security/keytabs/zookeeper.keytab" storeKey=true useTicketCache=false serviceName="zookeeper" principal=" zookeeper/[email protected]"; }; com.sun.security.jgss.krb5.initiate { com.sun.security.auth.module.Krb5LoginModule required renewTGT=false doNotPrompt=true useKeyTab=true keyTab="/etc/security/keytabs/kafka.keytab" storeKey=true useTicketCache=false serviceName="kafka" principal="kafka/[email protected]"; }; 注意修改principal、keyTab路径和serviceName以匹配实际环境。 修改Kafka的启动脚本： 在Kafka的启动脚本中添加JVM参数，指定JAAS配置文件的路径。 cat kafka_client_jaas.conf kafkaClient { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true storeKey=true serviceName=kafka keyTab="/etc/security/keytabs/kafka.keytab" principal="kafka/[email protected]";
