redhat6.4下面安装kerberos

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

1、安装rpm包
rpm -ivh krb5-libs-1.10.3-10.el6.x86_64.rpm
rpm -ivh krb5-server-1.10.3-10.el6.x86_64.rpm
rpm -ivh krb5-workstation-1.10.3-10.el6.x86_64.rpm

2、配置文件
/var/kerberos/krb5kdc/kdc.conf
  内容如下：
  [kdcdefaults]
   kdc_ports = 750,88

  [realms]
   psy.com = {
   database_name=/var/kerberos/krb5kdc/principal
   admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab
   acl_file = /var/kerberos/krb5kdc/kadm5.acl
   key_stash_file=/var/kerberos/krb5kdc/.k5.psy.com
   kdc_ports=750,88
   max_life=10h 0m 0s
   max_renewable_life=7d 0h 0m 0s
  }
/etc/krb5.conf
  [logging]
   default = FILE:/var/log/krb5libs.log
   kdc = FILE:/var/log/krb5kdc.log
   admin_server = FILE:/var/log/kadmind.log

  [libdefaults]
   default_realm = psy.com
   dns_lookup_realm = false
   dns_lookup_kdc = false
   ticket_lifetime = 24h
   renew_lifetime = 7d
   forwardable = true

  [realms]
   psy.com = {
   kdc = worknode
   admin_server = worknode
   }

3、生成数据库
kdb5_util create -r psy.com -s

4、创建管理用户
运行kadmin.local
addprinc admin/admin@psy.com
ktadd -k /var/kerberos/krb5kdc/kadm5.keytab kadmin/admin kadmin/changepw

5、编辑/etc/services
# # Kerberos (Project Athena/MIT) services
#kerberos 88/udp kdc # Kerberos 5 kdc
#kerberos 88/tcp kdc # Kerberos 5 kdc
#klogin 543/tcp # Kerberos rlogin -kfall
#kshell 544/tcp krcmd # Kerberos remote shell -kfall
krb5_prop 754/tcp # Kerberos v5 slave propagation
kerberos-adm 749/tcp # Kerberos v5 admin/chpwd
kerberos-adm 749/udp # Kerberos v5 admin/chpwd
#eklogin 2105/tcp # Kerberos encrypted rlogin -kfall
kpasswd 761/tcp kpwd # Kerberos "passwd" -kfall
#ktelnet 545/tcp # Kerberized telnet v4/v5
#kftp-data 546/tcp # Kerberized ftp data V5
#kftp 547/tcp # Kerberized ftp v5

6、重启krb5kdc 和kadmin服务
/etc/init.d/krb5kdc restart
/etc/init.d/kadmin restart

7、本机测试客户端连接
kinit admin/admin

8、远程客户机测试连接
需要配置相同的kdc.conf和krb5.conf
然后测试kinit admin/admin

问题：
[root@hadoop Packages]# kdb5_util create -r psy.com -s
Loading random data

通常是配置有问题，不是所有的EXAMPE.COM 都被替换成psy.com了。也有可能是创建的时间长一点。
