kerberos生成principal
## 创建principal
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey zookeeper/orchome@EXAMPLE.COM'
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey kafka/orchome@EXAMPLE.COM'
sudo /usr/sbin/kadmin.local -q 'addprinc -randkey clients/orchome@EXAMPLE.COM'
sudo /usr/sbin/kadmin.local -q "ktadd -k /etc/security/keytabs/kafka_server.keytab kafka/[email protected]"
sudo /usr/sbin/kadmin.local -q "ktadd -k /etc/security/keytabs/kafka_server.keytab zookeeper/[email protected]"
sudo /usr/sbin/kadmin.local -q "ktadd -k /etc/security/keytabs/kafka_client.keytab clients/[email protected]"
## 检查
klist -t -e -k /etc/security/keytabs/kafka_zookeeper.keytab
klist -t -e -k /etc/security/keytabs/kafka_server.keytab
klist -t -e -k /etc/security/keytabs/kafka_client.keytab
