部署Kerberos

安装

java环境

使用java 安全类库，要替换自带的。
下载jce_policy-8.zip后：

ansible all --become -m shell  -a "ls -l /mnt/kbdsproject/jdk/jre/lib/security/"
ansible all --become -m shell  -a "rm -f  /mnt/kbdsproject/jdk/jre/lib/security/US_export_policy.jar"
ansible all --become -m shell  -a "rm -f  /mnt/kbdsproject/jdk/jre/lib/security/local_policy.jar


rz -be
unzip jce_policy-8.zip
cd UnlimitedJCEPolicyJDK8/
ll
ansible all -m copy -a "scr=/home/hadoop/UnlimitedJCEPolicyJDK8/local_policy.jar dest=/mnt/kbdsproject/jdk/jre/lib/security/"
ansible all --become -m copy -a "scr=/home/hadoop/UnlimitedJCEPolicyJDK8/local_policy.jar dest=/mnt/kbdsproject/jdk/jre/lib/security/"
ansible all --become -m copy -a "src=/home/hadoop/UnlimitedJCEPolicyJDK8/local_policy.jar dest=/mnt/kbdsproject/jdk/jre/lib/security/"
ansible all --become -m copy -a "src=/home/hadoop/UnlimitedJCEPolicyJDK8/US_export_policy.jar  dest=/mnt/kbdsproject/jdk/jre/lib/security/"

配置

服务端

more /etc/krb5.conf

使用已经部署的KDC，怎么管理呢？F

[root@v-app2-cloud krb5kdc]# kadmin.local -r KDBS.COM -p kadmin/admin@KDBS.COM
Authenticating as principal kadmin/admin@KDBS.COM with password.
kadmin.local: Cannot find master key record in database while initializing kadmin.local interface

解决方法：
重新执行创建数据库
还是不行：

客户端

• 安装

yum install krb5-workstation

• 修改 /etc/krb5.conf，跟服务端一样
