apt-get install krb5-admin-server krb5-kdc krb5-user krb5-config
systemctl status krb5-admin-server
systemctl status krb5-kdc
systemctl start krb5-admin-server
systemctl startkrb5-kdc
vi /etc/krb5.conf
查看服务器名称
default_realm = CECGW.CN
# The following krb5.conf variables are only for MIT Kerberos.
kdc_timesync = 1
ccache_type = 4
forwardable = true
proxiable = true
[realms]
CECGW.CN = {
kdc = ubuntu
admin_server = ubuntu
}
创建数据库
cd /etc/krb5kdc
kdb5_util create -r CECGW.CN -s
输入俩次数据库密码
创建用户principal
kadmin.local
add_principal oneandonly/kerberos@CECGW.CN
输入俩次密码 oneandonly/kerberos@CECGW.CN
导出文件
xst -k oneandonly.keytab -norandkey oneandonly/kerberos@CECGW.CN
验证登录,使用密钥登录.
root@ubuntu:/opt/kafka/kafka_2.13-3.6.1# kinit -kt oneandonly.keytab oneandonly/kerberos
root@ubuntu:/opt/kafka/kafka_2.13-3.6.1# klist
退出登录
root@ubuntu:/opt/kafka/kafka_2.13-3.6.1# kdestroy
root@ubuntu:/opt/kafka/kafka_2.13-3.6.1# klist

复制 bin/kafka-server-start.sh 脚本重命名为 bin/kafka-server-start-sasl.sh,倒数第二行增加如下配置
export KAFKA_OPTS="-Dzookeeper.sasl.client=false -Dzookeeper.sasl.client.username=zk-server -Djava.security.krb5.conf=/opt/kafka/kafka_2.13-3.6.1/config/kerberos/krb5.conf -Djava.security.auth.login.config=/opt/kafka/kafka_2.13-3.6.1/config/kerberos/kafka-server-jaas.conf"
.新建 kafka-client-jaas.conf 文件,该文件也放到 Kafka 的 config/kerberos 目录下。
security.protocol=SASL_PLAINTEXT
sasl.mechanism=GSSAPI
sasl.kerberos.service.name=kafka-server
KafkaClient {

};

cd /opt/kafka/kafka_2.13-3.6.1
nohup bin/zookeeper-server-start.sh config/zookeeper.properties > /dev/null 2>&1 &
