kerberos安装
kerberos安装
1.server端
# yum install -y krb5-server krb5-libs krb5-auth-dialog
client端
# yum install -y krb5-workstation krb5-libs krb5-auth-dialog
各机器上均虚安装openssl
# yum install krb5-pkinit-openssl
//修改/etc/krb5.conf
vim /etc/krb5.conf

#default_principal_flags = +renewable, +forwardable
}
拷贝krb5.conf到集群中其他机器上
修改kadm5.acl
创建krb数据库
kdb5_util create -r HADOOP.COM -s
//启动kdc服务器
/sbin/service krb5kdc start
/sbin/service kadmin start
chkconfig --level 35 krb5kdc on
chkconfig --level 35 kadmin on
创建管理员用户 cloudera/admin 123456
cm里点击主机 重新运行安装向导 升级java包
整理的升级指的是启用java里的jce功能，jce是负责安全模块,去网上下载jce自行安装也是可以的。
