CDH6集成kerberos

作者: sysit 分类: d 发表于 2019-04-09 513人围观

## 1. 前置条件
* kerberos已经安装并正确配置，见《kerberos高可用安装与配置》
* CDH安装完成，见《CDH6.2.0安装配置手册》

## 2 安装配置kerberos 客户端

* 集群安装kerberos包

```
#为集群安装所有Kerberos客户端，包括Cloudera Manager

yum -y install krb5-libs krb5-workstation

# 在cloudera-manager-server节点上安装额外的包

yum install openldap-clients -y
```

* 将KDC Server上的krb5.conf文件拷贝到所有Kerberos客户端

```
scp krb-1.sysit.cn:/etc/krb5.conf /etc/krb5.conf
```

* 在KDC中给Cloudera Manager添加管理员账号

```
root@krb-1 ~]# kadmin.local
Authenticating as principal root/admin@SYSIT.CN with password.
kadmin.local:  addprinc cloudera-scm/admin@SYSIT.CN
WARNING: no policy specified for cloudera-scm/admin@SYSIT.CN; defaulting to no policy
Enter password for principal "cloudera-scm/admin@SYSIT.CN": 
Re-enter password for principal "cloudera-scm/admin@SYSIT.CN": 
Principal "cloudera-scm/admin@SYSIT.CN" created.
kadmin.local:  exit
```

## 3 cdh启用kerberos

进入Cloudera Manager的“Administration”-> “Security”界面

![title](/api/file/getImage?fileId=5cac6ec53cd7c905220001e8)

![title](/api/file/getImage?fileId=5cac6edf3cd7c905220001e9)

选择“Enable Kerberos”，进入如下界面：

确保如下列出的所有检查项都已完成

![title](/api/file/getImage?fileId=5cac6efe3cd7c905220001ea)

点击“Continue”，配置相关的KDC信息，包括类型、KDC服务器、KDC Realm、加密类型以及待创建的Service Principal（hdfs，yarn,，hbase，hive等）的更新生命期等

![title](/api/file/getImage?fileId=5cac6f2d3cd7c905220001eb)

点击“Continue”

![title](/api/file/getImage?fileId=5cac6f413cd7c905220001ec)

不建议让Cloudera Manager来管理krb5.conf, 点击“Continue”

![title](/api/file/getImage?fileId=5cac6fa43cd7c905220001ee)

输入Cloudera Manager的Kerbers管理员账号，必须和之前创建的账号一致，否则会提示错误，点击“Continue”进入下一步。

![title](/api/file/getImage?fileId=5cac6fcb3cd7c905220001ef)

导入完成，点击“Continue”进入下一步。

![title](/api/file/getImage?fileId=5cac70053cd7c905220001f0)

点击“Continue”进入下一步。

![title](/api/file/getImage?fileId=5cac711c3cd7c905220001f1)

等待安装完成后，点击“Continue”进入下一步。

![title](/api/file/getImage?fileId=5cac71403cd7c905220001f2)

提示成功，点击“Finish”。

## 4 使用kerberos

### 4.1 创建一个用户来测试kerberos

创建一个用户admin，在操作系统中也应该有admin这个账号。
```
[root@krb-1 ~]# kadmin.local
Authenticating as principal root/admin@SYSIT.CN with password.
kadmin.local:  addprinc admin@SYSIT.CN
WARNING: no policy specified for admin@SYSIT.CN; defaulting to no policy
Enter password for principal "admin@SYSIT.CN": 
Re-enter password for principal "admin@SYSIT.CN": 
Principal "admin@SYSIT.CN" created.
kadmin.local:  exit
```

### 4.2 使用kerberos访问hdfs

在没有经过kerberos认证的时候，执行hdfs dfs -ls /出现如下信息：
```
[admin@cdh-1 ~]$ hdfs dfs -ls /
19/04/09 20:54:19 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]
19/04/09 20:54:19 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]
19/04/09 20:54:19 INFO retry.RetryInvocationHandler: java.io.IOException: Failed on local exception: java.io.IOException: org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]; Host Details : local host is: "cdh-1.sysit.cn/10.50.101.106"; destination host is: "cdh-2.sysit.cn":8020; , while invoking ClientNamenodeProtocolTranslatorPB.getFileInfo over cdh-2.sysit.cn/10.50.101.64:8020 after 1 failover attempts. Trying to failover after sleeping for 754ms.
```

我们重新获取kerberos 认证后执行。

```
[admin@cdh-1 ~]$ kinit admin@SYSIT.CN
Password for admin@SYSIT.CN: 
[admin@cdh-1 ~]$ hdfs dfs -ls /      
Found 2 items
drwxrwxrwt   - hdfs supergroup          0 2019-04-09 17:07 /tmp
drwxr-xr-x   - hdfs supergroup          0 2019-04-09 17:33 /user
```

### 4.3 运行mapReduce作业

```
[admin@cdh-5 ~]$  hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples-3.0.0-cdh6.2.0.jar pi 10 1
