生活随笔收集整理的這篇文章主要介紹了 Hadoop Kerberos 认证下 Sentry 安装 + Sentry 权限设置使用小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

一、安裝Sentry

１.ＭariaDB中創建sentry數據庫

2.CDH中添加sentry 服務

3.hive配置啟動Sentry

4.Impala配置啟動Sentry

5.Hue配置啟動Sentry

6.Hdfs配置啟動Sentry

7.重啟服務，使配置生效

二、Sentry權限測試

1.創建hive超級用戶

? 1.1 創建kerberos hive用戶

1.2創建Admin角色

?1.3為admin角色賦予管理員權限

1.4 將admin角色授權給hive用戶組

2. 創建test表

Sentry 介紹：　https://datamining.blog.csdn.net/article/details/98969244

一、安裝Sentry

１.ＭariaDB中創建sentry數據庫

MariaDB [(none)]> create database sentry default character set utf8; Query OK, 1 row affected (0.01 sec)MariaDB [(none)]> CREATE USER 'sentry'@'%' IDENTIFIED BY 'password'; Query OK, 0 rows affected (0.03 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON sentry. * TO 'sentry'@'%'; Query OK, 0 rows affected (0.01 sec)MariaDB [(none)]> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)

2.CDH中添加sentry 服務

填寫剛剛創建數據庫信息

?繼續安裝完成

3.hive配置啟動Sentry

啟動hive Sentry

取消模擬用戶身份提交

啟用數據庫中的存儲通知

保存

4.Impala配置啟動Sentry

5.Hue配置啟動Sentry

6.Hdfs配置啟動Sentry

啟動HDFS ACL控制，與Sentry權限同步

7.重啟服務，使配置生效

至此服務安裝成功

二、Sentry權限測試

1.創建hive超級用戶

? 1.1 創建kerberos hive用戶

[root@xxx ~]# kadmin.local Authenticating as principal hbase/admin@JAST.COM with password. kadmin.local: addprinc hive@JAST.COM WARNING: no policy specified for hive@JAST.COM; defaulting to no policy Enter password for principal "hive@JAST.COM": Re-enter password for principal "hive@JAST.COM": Principal "hive@JAST.COM" created. kadmin.local: exit [root@xxx ~]# kinit hive Password for hive@JAST.COM: [root@xxx ~]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: hive@JAST.COMValid starting Expires Service principal 2019-08-09T10:07:24 2019-08-10T10:07:24 krbtgt/JAST.COM@JAST.COMrenew until 2019-08-17T10:07:24

通過 beeline連接 hiveserver2

[root@xxx001 ~]# beeline Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0 Beeline version 1.1.0-cdh5.13.0 by Apache Hive beeline> !connect jdbc:hive2://192.168.1.101:10000/;principal=hive@JAST.COM scan complete in 2ms Connecting to jdbc:hive2://192.168.1.101:10000/;principal=hive@JAST.COM Kerberos principal should have 3 parts: hive@JAST.COM

這里就遇到問題了，提示?Kerberos principal should have 3 parts: hive@JAST.COM ，說是需要三個部分，翻閱資料發現創建kerberos principal指定三個部分，命名規則類似于：服務名/HOST@域名，域名就是/etc/krb5.conf 中 domain_realm 配置的，如 hive/hostname1@JAST.COM

此處參考：https://community.hortonworks.com/questions/22897/kerberos-principal-should-have-3-parts.html

注意這里hostname要與hiveserver2的相同，例：

!connect jdbc:hive2://hostname:10000/;principal=hive/hostname@JAST.COM

不相同會報錯：

Error: Could not open client transport with JDBC Uri: jdbc:hive2://hostname:10000/;principal=hive/hostname1@JAST.COM: GSS initiate failed (state=08S01,code=0)

?修改第一步創建principal

[root@xxx ~]# kadmin.local Authenticating as principal hbase/admin@JAST.COM with password. kadmin.local: addprinc hive/hostname@JAST.COM WARNING: no policy specified for hive/hostname@JAST.COM; defaulting to no policy Enter password for principal "hive/hostname@JAST.COM": Re-enter password for principal "hive/hostname@JAST.COM": Principal "hive/hostname@JAST.COM" created. kadmin.local: exit [root@xxx ~]# kinit hive Password for hive/hostname@JAST.COM: [root@xxx ~]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: hive/hostname@JAST.COMValid starting Expires Service principal 2019-08-09T10:07:24 2019-08-10T10:07:24 krbtgt/JAST.COM@JAST.COMrenew until 2019-08-17T10:07:24

再次通過beeline連接,成功

beeline> !connect jdbc:hive2://hostname:10000/;principal=hive/hostname@JAST.COM Connecting to jdbc:hive2://hostname:10000/;principal=hive/hostname@JAST.COM Connected to: Apache Hive (version 1.1.0-cdh5.13.0) Driver: Hive JDBC (version 1.1.0-cdh5.13.0) Transaction isolation: TRANSACTION_REPEATABLE_READ 0: jdbc:hive2://hostname:10000/>

1.2創建Admin角色

0: jdbc:hive2://xxx:10000/> create role admin; INFO : Compiling command(queryId=hive_20190811133535_e7b93b4e-ee8e-4aee-b0ce-49b62bda60c8): create role admin INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811133535_e7b93b4e-ee8e-4aee-b0ce-49b62bda60c8); Time taken: 0.532 seconds INFO : Executing command(queryId=hive_20190811133535_e7b93b4e-ee8e-4aee-b0ce-49b62bda60c8): create role admin INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811133535_e7b93b4e-ee8e-4aee-b0ce-49b62bda60c8); Time taken: 0.204 seconds INFO : OK No rows affected (2.118 seconds)

?1.3為admin角色賦予管理員權限

0: jdbc:hive2://XXX:10000/> GRANT ALL ON SERVER server1 TO ROLE admin; INFO : Compiling command(queryId=hive_20190811134141_549bde26-29b1-48fc-a5b1-62ffe2ced6e9): GRANT ALL ON SERVER server1 TO ROLE admin INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811134141_549bde26-29b1-48fc-a5b1-62ffe2ced6e9); Time taken: 0.12 seconds INFO : Executing command(queryId=hive_20190811134141_549bde26-29b1-48fc-a5b1-62ffe2ced6e9): GRANT ALL ON SERVER server1 TO ROLE admin INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811134141_549bde26-29b1-48fc-a5b1-62ffe2ced6e9); Time taken: 0.104 seconds INFO : OK No rows affected (0.241 seconds)

1.4 將admin角色授權給hive用戶組

0: jdbc:hive2://xxx:10000/> GRANT ROLE admin TO GROUP hive; INFO : Compiling command(queryId=hive_20190811134242_2e020ff8-08ee-4b68-a19c-ff83b68a24ae): GRANT ROLE admin TO GROUP hive INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811134242_2e020ff8-08ee-4b68-a19c-ff83b68a24ae); Time taken: 0.088 seconds INFO : Executing command(queryId=hive_20190811134242_2e020ff8-08ee-4b68-a19c-ff83b68a24ae): GRANT ROLE admin TO GROUP hive INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811134242_2e020ff8-08ee-4b68-a19c-ff83b68a24ae); Time taken: 0.061 seconds INFO : OK No rows affected (0.163 seconds)

?以上操作創建了一個admin角色：

admin :?具有管理員權限，可以讀寫所有數據庫，并授權給hive組（對應操作系統的組）

2. 創建test表

使用hive用戶登錄Kerberos，通過beeline登錄HiveServer2，創建test表，并插入測試數據

0: jdbc:hive2://xxx:10000/> create table test (s1 string, s2 string) row format delimited fields terminated by ','; INFO : Compiling command(queryId=hive_20190811134747_3bf78819-78e0-4f3f-921d-57aae50184ab): create table test (s1 string, s2 string) row format delimited fields terminated by ',' INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811134747_3bf78819-78e0-4f3f-921d-57aae50184ab); Time taken: 0.352 seconds INFO : Executing command(queryId=hive_20190811134747_3bf78819-78e0-4f3f-921d-57aae50184ab): create table test (s1 string, s2 string) row format delimited fields terminated by ',' INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811134747_3bf78819-78e0-4f3f-921d-57aae50184ab); Time taken: 0.465 seconds INFO : OK No rows affected (0.856 seconds)

?插入數據

0: jdbc:hive2://hostname:10000/> insert into test values('a','b'),('1','2'); INFO : Compiling command(queryId=hive_20190811134848_7d61ee56-7e53-4889-bd3b-7833bbe45793): insert into test values('a','b'),('1','2') INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:[FieldSchema(name:values__tmp__table__1.tmp_values_col1, type:string, comment:null), FieldSchema(name:values__tmp__table__1.tmp_values_col2, type:string, comment:null)], properties:null) INFO : Completed compiling command(queryId=hive_20190811134848_7d61ee56-7e53-4889-bd3b-7833bbe45793); Time taken: 0.856 seconds INFO : Executing command(queryId=hive_20190811134848_7d61ee56-7e53-4889-bd3b-7833bbe45793): insert into test values('a','b'),('1','2') INFO : Query ID = hive_20190811134848_7d61ee56-7e53-4889-bd3b-7833bbe45793 INFO : Total jobs = 3 INFO : Launching Job 1 out of 3 INFO : Starting task [Stage-1:MAPRED] in serial mode INFO : Number of reduce tasks is set to 0 since there's no reduce operator INFO : number of splits:1 INFO : Submitting tokens for job: job_1565402085038_0001 INFO : Kind: HDFS_DELEGATION_TOKEN, Service: 10.248.161.16:8020, Ident: (token for hive: HDFS_DELEGATION_TOKEN owner=hive/hostname.zh@IZHONGHONG.COM, renewer=yarn, realUser=, issueDate=1565502522452, maxDate=1566107322452, sequenceNumber=62, masterKeyId=8) INFO : The url to track the job: http://hostname.zh:8088/proxy/application_1565402085038_0001/ INFO : Starting Job = job_1565402085038_0001, Tracking URL = http://hostname.zh:8088/proxy/application_1565402085038_0001/ INFO : Kill Command = /opt/cloudera/parcels/CDH-5.13.0-1.cdh5.13.0.p0.29/lib/hadoop/bin/hadoop job -kill job_1565402085038_0001 INFO : Hadoop job information for Stage-1: number of mappers: 1; number of reducers: 0 INFO : 2019-08-11 13:48:56,862 Stage-1 map = 0%, reduce = 0% INFO : 2019-08-11 13:49:02,147 Stage-1 map = 100%, reduce = 0%, Cumulative CPU 2.08 sec INFO : MapReduce Total cumulative CPU time: 2 seconds 80 msec INFO : Ended Job = job_1565402085038_0001 INFO : Starting task [Stage-7:CONDITIONAL] in serial mode INFO : Stage-4 is selected by condition resolver.

?查詢數據

0: jdbc:hive2://hostname:10000/> select * from test; INFO : Compiling command(queryId=hive_20190811134949_edeab35a-b1ae-49b8-b4b7-8281ae736fa8): select * from test INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:[FieldSchema(name:test.s1, type:string, comment:null), FieldSchema(name:test.s2, type:string, comment:null)], properties:null) INFO : Completed compiling command(queryId=hive_20190811134949_edeab35a-b1ae-49b8-b4b7-8281ae736fa8); Time taken: 0.201 seconds INFO : Executing command(queryId=hive_20190811134949_edeab35a-b1ae-49b8-b4b7-8281ae736fa8): select * from test INFO : Completed executing command(queryId=hive_20190811134949_edeab35a-b1ae-49b8-b4b7-8281ae736fa8); Time taken: 0.0 seconds INFO : OK +----------+----------+--+ | test.s1 | test.s2 | +----------+----------+--+ | a | b | | 1 | 2 | +----------+----------+--+ 2 rows selected (0.345 seconds)

3. 創建其他角色，授予權限

?創建兩個角色：jast_r 與 jast_w ，一個是讀權限，一個是寫權限

注意：集群所有節點必須存在fayson和user_w用戶，用戶默認用戶組與用戶名一致，賦權是針對用戶組而不是針對用戶。

3.1 創建用戶，默認用戶組與用戶名相同

[root@hostname ~]# useradd jast_r [root@hostname ~]# id jast_r uid=1002(jast_r) gid=1002(jast_r) 組=1002(jast_r) [root@hostname ~]# useradd jast_w [root@hostname ~]# id jast_w uid=1003(jast_w) gid=1003(jast_w) 組=1003(jast_w)

?3.2?授權read角色對test表的select權限，write角色對test表的insert權限

0: jdbc:hive2://hostname:10000/> create role read; INFO : Compiling command(queryId=hive_20190811140000_d4a8362b-c976-4a83-a189-c806ba909f2b): create role read INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140000_d4a8362b-c976-4a83-a189-c806ba909f2b); Time taken: 0.082 seconds INFO : Executing command(queryId=hive_20190811140000_d4a8362b-c976-4a83-a189-c806ba909f2b): create role read INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140000_d4a8362b-c976-4a83-a189-c806ba909f2b); Time taken: 0.024 seconds INFO : OK No rows affected (0.12 seconds) 0: jdbc:hive2://hostname:10000/> GRANT SELECT ON TABLE test TO ROLE read; INFO : Compiling command(queryId=hive_20190811140000_df975a0d-1eef-4e80-adea-c0a5a2a83370): GRANT SELECT ON TABLE test TO ROLE read INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140000_df975a0d-1eef-4e80-adea-c0a5a2a83370); Time taken: 0.089 seconds INFO : Executing command(queryId=hive_20190811140000_df975a0d-1eef-4e80-adea-c0a5a2a83370): GRANT SELECT ON TABLE test TO ROLE read INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140000_df975a0d-1eef-4e80-adea-c0a5a2a83370); Time taken: 0.025 seconds INFO : OK No rows affected (0.125 seconds) 0: jdbc:hive2://hostname:10000/> CREATE ROLE write; INFO : Compiling command(queryId=hive_20190811140101_5688fe84-9e95-49e3-86df-5bf599ab31c7): CREATE ROLE write INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140101_5688fe84-9e95-49e3-86df-5bf599ab31c7); Time taken: 0.091 seconds INFO : Executing command(queryId=hive_20190811140101_5688fe84-9e95-49e3-86df-5bf599ab31c7): CREATE ROLE write INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140101_5688fe84-9e95-49e3-86df-5bf599ab31c7); Time taken: 0.012 seconds INFO : OK No rows affected (0.113 seconds) 0: jdbc:hive2://hostname:10000/> GRANT INSERT ON TABLE test TO ROLE write; INFO : Compiling command(queryId=hive_20190811140202_4ac6ca45-9829-47ae-893e-376778c17030): GRANT INSERT ON TABLE test TO ROLE write INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140202_4ac6ca45-9829-47ae-893e-376778c17030); Time taken: 0.082 seconds INFO : Executing command(queryId=hive_20190811140202_4ac6ca45-9829-47ae-893e-376778c17030): GRANT INSERT ON TABLE test TO ROLE write INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140202_4ac6ca45-9829-47ae-893e-376778c17030); Time taken: 0.014 seconds INFO : OK No rows affected (0.107 seconds)

?3.3?將read角色授權給 jast_r 用戶組，write角色授權給 jast_w 用戶組

0: jdbc:hive2://hostname:10000/> GRANT ROLE read TO GROUP jast_r; INFO : Compiling command(queryId=hive_20190811140303_914d96ac-577e-49fd-99a4-69e6ef2c977c): GRANT ROLE read TO GROUP jast_r INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140303_914d96ac-577e-49fd-99a4-69e6ef2c977c); Time taken: 0.082 seconds INFO : Executing command(queryId=hive_20190811140303_914d96ac-577e-49fd-99a4-69e6ef2c977c): GRANT ROLE read TO GROUP jast_r INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140303_914d96ac-577e-49fd-99a4-69e6ef2c977c); Time taken: 0.02 seconds INFO : OK No rows affected (0.112 seconds) 0: jdbc:hive2://hostname:10000/> GRANT ROLE write TO GROUP jast_w; INFO : Compiling command(queryId=hive_20190811140303_0f5e0d44-e853-4ffe-a184-f3c5beebf46f): GRANT ROLE write TO GROUP jast_w INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20190811140303_0f5e0d44-e853-4ffe-a184-f3c5beebf46f); Time taken: 0.081 seconds INFO : Executing command(queryId=hive_20190811140303_0f5e0d44-e853-4ffe-a184-f3c5beebf46f): GRANT ROLE write TO GROUP jast_w INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20190811140303_0f5e0d44-e853-4ffe-a184-f3c5beebf46f); Time taken: 0.011 seconds INFO : OK No rows affected (0.1 seconds)

?3.4?使用kadmin創建 jast_r 和 jast_w 用戶

[root@xxx ~]# kadmin.local Authenticating as principal hive/admin@JAST.COM with password. kadmin.local: addprinc jast_r@JAST.COM WARNING: no policy specified for jast_r@JAST.COM; defaulting to no policy Enter password for principal "jast_r@JAST.COM": Re-enter password for principal "jast_r@JAST.COM": Principal "jast_r@JAST.COM" created. kadmin.local: addprinc jast_w@JAST.COM WARNING: no policy specified for jast_w@JAST.COM; defaulting to no policy Enter password for principal "jast_w@JAST.COM": Re-enter password for principal "jast_w@JAST.COM": Principal "jast_w@JAST.COM" created. kadmin.local: exit

?3.5 Hive 驗證

使用 jast_r 用戶登錄kerberos

[root@xxx ~]# kinit jast_r Password for jast_r@JAST.COM: [root@xxx ~]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: jast_r@JAST.COMValid starting Expires Service principal 2019-08-11T14:10:15 2019-08-12T14:10:15 krbtgt/JAST.COM@JAST.COMrenew until 2019-08-18T14:10:15

?我們發現，

讀用戶可以讀取所有內容，但是不能刪除和添加hdfs中內容

寫用戶可以讀取非hive目錄下的文件，但是不能讀取hive/warehouse目錄下的的數據，可以寫入數據，但是也不能刪除數據（這個和網上部分資料說的不太相同，我又測了一下，使用hive用用戶的話是可以刪除的，jast_w 就是不可以）

說明hive的權限對hdfs權限是同步的

?3.7 HUE 驗證

在HUE中創建 read_r 與 read_w 用戶，登錄查詢hive測試，結果相同

?3.8 Impala 驗證

kerberos 登錄 jast_r 用戶

Impala與Sentry集成后可以使用Sentry來進行權限管理，擁有read角色的fayson用戶組只能對test表進行select和count操作不能插入數據，擁有write角色的user_w

用戶組只能對test表插入數據不能進行select和count操作。說明Sentry實現了Hive權限與Impala的同步。

4. Sentry 列權限設置

其實這里的步驟就是：創建kerberos 賬號 ->創建 role -> 給role賦予相關權限 -> 給用戶/用戶組賦予role權限?

kerberos 登錄hive用戶，鏈接hiveserver2

4.1?創建test表列讀角色并授權給用戶組?

?發現，我們只能查看我們指定的列

去hdfs查看是否有權限查看數據

發現無權限查看hive中的數據

注意：Sentry只支持SELECT的列授權，不能用于INSERT和ALL的列授權。?

5. Sentry 權限命令詳解（更多介紹參考：https://datamining.blog.csdn.net/article/details/99212770）

#權限分為 SELECT ,INSERT ,ALL #查看所有role show roles;#創建role create role role_name;#刪除rolt drop role role_name; #將某個數據庫讀權限授予給某個role GRANT SELECT ON DATABASE db_name TO ROLE role_name;#將test 表的 S1 列的讀權限授權給role_name （TABLE也可以不寫） GRANT SELECT(s1) ON TABLE test TO ROLE role_name;
