Ambari2.6.2集成Kerberos

名词解释

Kerberos: Network Authentication protocol（网络认证协议）
KDC: Key Distribution center（密钥分配中心）
Kadmin: Kerberos Administrator（Kerberos管理）

我这边环境是docker 安装的单节点 Ambari

1配置/etc/hosts

在ip 后面加上kerberos-auth

127.0.0.1	localhost
172.18.0.3    sandbox-hdp.hortonworks.com sandbox-hdp  kerberos-auth

2安装Kerberos

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

3配置Kerberos Server配置文件

[root@ambari-agent01 ~]$ cat /etc/krb5.conf
# Configuration snippets may be placed in this directory as well
includedir /etc/krb5.conf.d/

[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h     # 认证凭证生命周期
 renew_lifetime = 7d      # 认证凭证最长延期时限
 forwardable = true
 renewable = true
 rdns = false
 pkinit_anchors = /etc/pki/tls/certs/ca-bundle.crt
 default_realm = TEST.COM
 default_ccache_name = KEYRING:persistent:%{uid}

[realms]
TEST.COM = {
  kdc = kerberos-auth            # TEST.COM 域中的 KDC 接口 为我们刚才添加的主机名，下同
  admin_server = kerberos-auth  # TEST.COM 域中的 Admin Server 接口
}

[domain_realm]
.TEST.com = TEST.COM
TEST.com = TEST.COM

 

4管理帐号 ACL 配置

[root@ambari-agent01 ~]$ cat /var/kerberos/krb5kdc/kadm5.acl
*/[email protected]        *

5初始化并创建 Kerberos 数据库

重新创建数据则是清空该 /ar/kerberos/krb5kdc/目录下principal相关文件，再重新执行一下命令

[root@ambari-agent01 ~]$ kdb5_util create -r TEST.COM -s
Loading random data
Initializing database '/var/kerberos/krb5kdc/principal' for realm 'TEST.COM',
master key name 'K/[email protected]'
You will be prompted for the database Master Password.
It is important that you NOT FORGET this password.
Enter KDC database master key:                                  # 设置密码
Re-enter KDC database master key to verify:               # 确认密码

6创建管理帐号 Principal

[root@ambari-agent01 krb5kdc]$ kadmin.local -q "addprinc admin/admin"
Authenticating as principal root/[email protected] with password.
WARNING: no policy specified for admin/[email protected]; defaulting to no policy
Enter password for principal "admin/[email protected]":          # 设置管理帐号密码
Re-enter password for principal "admin/[email protected]":    # 确认密码
Principal "admin/[email protected]" created.

7查看 Kerberos 数据库帐号列表

[root@ambari-agent01 krb5kdc]$ kadmin.local listprincs
K/[email protected]
admin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kadmin/[email protected]
kiprop/[email protected]
krbtgt/[email protected]

8启动 Kerberos-Server

systemctl start krb5kdc.service

9启动 Kadmin-Server

systemctl start kadmin.service

配置Ambari集成Kerberos，Ambari页面配置

 

 

 

配置并测试KDC连通性

配置测试kadmin连通性并继续

# 在 Admin Principal 和 Admin Password 中填入手动创建的管理帐号与帐号密码
# 创建的帐号为 admin/[email protected] 注意：账号输入不正确则会Test Kerberos Clients会报找不到databases

接下来按步骤安装即可完成！
