Ambari启用Kerberos认证

演示环境

Centos7.4
Ambari-2.6.2.0

使用指南

PS: 以下带#号注释的都是修改的内容

在Server机子上安装Kerberos

yum install krb5-server krb5-libs krb5-workstation -y

修改主配置krb5.conf文件
cat /etc/krb5.conf

[libdefaults]
  renew_lifetime = 7d
  forwardable = true
  default_realm = FLINK.COM #Realm名
  ticket_lifetime = 24h
  dns_lookup_realm = false
  dns_lookup_kdc = false
  default_ccache_name = /tmp/krb5cc_%{uid}

[logging]
  default = FILE:/var/log/krb5kdc.log
  admin_server = FILE:/var/log/kadmind.log
  kdc = FILE:/var/log/krb5kdc.log

[realms]
  FLINK.COM = {
    admin_server = 10.3.111.0 #IP或者是主机名
    kdc = 10.3.111.0 #IP或者是主机名
  }

编辑Kdc文件
cat /var/kerberos/krb5kdc/kdc.conf

[kdcdefaults]
 kdc_ports = 88
 kdc_tcp_ports = 88

[realms]
 FLINK.COM = { #对应名称
  master_key_type = aes256-cts
  acl_file = /var/kerberos/krb5kdc/kadm5.acl
  dict_file = /usr/share/dict/words
  admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab
  supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal
 }

编辑acl文件
cat /var/kerberos/krb5kdc/kadm5.acl

*/admin@FLINK.COM   *

创建数据库
1.输入密码
2.输入确认密码

[root@storm1 ~]# kdb5_util create  -s -r FLINK.COM
Loading random data
Initializing database '/var/kerberos/krb5kdc/principal' for realm 'FLINK.COM',
master key name 'K/M@FLINK.COM'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key: 
Re-enter KDC database master key to verify:

创建管理员
1:输入两次上面的确认密码
2:输入退出

[root@storm1 ~]# kadmin.local 
Authenticating as principal root/admin@FLINK.COM with password.
kadmin.local:  addprinc admin/admin@FLINK.COM
WARNING: no policy specified for admin/admin@FLINK.COM; defaulting to no policy
Enter password for principal "admin/admin@FLINK.COM": 
Re-enter password for principal "admin/admin@FLINK.COM": 
Principal "admin/admin@FLINK.COM" created.
kadmin.local:  exit

重启服务

systemctl restart krb5kdc
systemctl restart kadmin

Ambari操作

打开启动Kerberos 勾选Kerberos 配置
测试配置正确 自定义配置 停止服务 安装Kerberize集群 验证完成
