【大数据安全】Apache Kylin 安全配置(Kerberos)
1. 概述 本文首先会简单介绍Kylin的安装配置，然后介绍启用Kerberos的CDH集群中如何部署及使用Kylin。 Apache Kylin™是一个开源的分布式分析引擎，提供Hadoop/Spark之上的SQL查询接口及多维分析（OLAP）能力以支持超大规模数据，最初由eBay Inc. 开发并贡献至开源社区。它能在亚秒内查询巨大的Hive表。 1.2 环境说明 CDH版本：5.11.2 Linux版本：7.4.1708 Docker版本：Docker version 18.06.0-ce JDK版本：1.8 操作用户：root 2.Kylin安装配置 2.1 安装 此处以Kylin 2.0.0版本为例。社区版Kylin地址：https://archive.apache.org/dist/kylin/ [root@node-3 ~]# cd /usr/local/src/ [root@node-3 src]# wget https://archive.apache.org/dist/kylin/apache-kylin-2.0.0/apache-kylin-2.0.0-bin-cdh57.tar.gz [root@node-3 src]# tar xf apache-kylin-2.0.0-bin-cdh57.tar.gz [root@node-3 src]# cp -a apache-kylin-2.0.0-bin /usr/local/ [root@node-3 src]# ln -s /usr/local/apache-kylin-2.0.0-bin /usr/local/kylin 2.2 环境配置 export BASE_PATH_BIG=/opt/cloudera/parcels/CDH/lib #added by Hbase export HBASE_HOME=$BASE_PATH_BIG/hbase #added by HCat export HCAT_HOME=/opt/cloudera/parcels/CDH/lib/hive-hcatalog/share/hcatalog #added by Kylin export KYLIN_HOME=/usr/local/kylin export PATH=$HBASE_HOME/bin:$PATH 然后执行source /etc/profile生效。 2.3 Kylin配置 编辑/usr/local/kylin/conf/kylin.properites文件，新增以下配置： Kylin2.0+版本配置的名称有变化，具体参考：https://github.com/apache/kylin/blob/2.0.x/core-common/src/main/resources/kylin-backward-compatibility.properties ## 修改配置（替换地址） kylin.rest.servers=192.168.100.102:7070 ## 新增配置 kylin.job.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-job-2.0.0.jar kylin.coprocessor.local.jar=/usr/local/apache-kylin-2.0.0-bin/lib/kylin-coprocessor-2.0.0.jar ## 替换地址 kylin.job.yarn.app.rest.check.status.url=http://cdh-node-2:8088/ws/v1/cluster/apps/${job_id}?anonymous=true kylin.job.mr.lib.dir=/opt/cloudera/parcels/CDH-5.11.2-1.cdh5.11.2.p0.4/lib/sentry/lib 配置说明： kylin.rest.servers：kylin实例服务器列表，注意：不包括以job模式运行的服务器实例！ kylin.job.jar：MR jobs依赖 kylin.coprocessor.local.jar：Hbase协同处理依赖，用于提高性能。 kylin.job.yarn.app.rest.check.status.url：yarn工作区 kylin.job.mr.lib.dir：Hive/Hbase依赖目录。（在没有安装Hive/Hbase的节点上构建Cube会因为找不到依赖报ClassNotFoundException错误，需要此配置。具体参考这边博文[《上传Kylin MR依赖》](http://www.whitewood.me/2017/11/04/Kylin%E5%AE%9E%E6%88%98%EF%BC%88%E5%85%AD%EF%BC%89%EF%BC%9A%E4%B8%8A%E4%BC%A0Kylin%20MR%E4%BE%9D%E8%B5%96/))。 更多配置请参考官网配置指南。 2.4 创建用户 在每个节点创建Kylin用户 useradd kylin 3. Kerberos配置 3.1 创建kylin账号 在Kerberos server上创建kylin账号： [root@cdh-node-1 /]# kadmin.local Authenticating as principal admin/admin@HWINFO.COM with password. kadmin.local: addprinc kylin WARNING: no policy specified for kylin@HWINFO.COM; defaulting to no policy Enter password for principal "kylin@HWINFO.COM": Re-enter password for principal "kylin@HWINFO.COM": add_principal: Principal or policy already exists while creating "kylin@HWINFO.COM". kadmin.local: 3.2 生成keytab文件 生成kylin账号keytab文件： xst -norandkey -k klin.keytab kylin@HWINFO.COM 将kylin.keytab复制到每个kylin节点上。 3.3 定时刷新kt 在kylin节点上配置定时任务进行kinit命令： kinit -k -t /root/kylin.keytab kylin@HWINFO.COM 添加定时任务,这里设置每天凌晨1点执行一次，可根据kerberos的过期时间自己配置。 编写shell脚本： [root@cdh-node-2 security]# cat init_kt.sh #!/bin/bash kinit -kt ./kylin.keytab kylin@HWINFO.COM 添加定时任务： [root@cdh-node-2 security]# crontab -e # 添加以下内容 0 1 * * * root /home/security/init_kt.sh > /tmp/kylin-ktinit.log 2>&1 # 查看定时任务 [root@cdh-node-2 security]# crontab -l 0 1 * * * root /home/security/init_kt.sh > /tmp/kylin-ktinit.log 2>&1 3.4 添加Hive权限 登录Hive使用拥有操作hive权限的kerberos账户登录beeline： [root@cdh-node-3 hive]# beeline -u 'jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM' 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 scan complete in 2ms Connecting to jdbc:hive2://cdh-node-3:10000/default;principal=hive/cdh-node-3@HWINFO.COM Connected to: Apache Hive (version 1.1.0-cdh5.11.2) Driver: Hive JDBC (version 1.1.0-cdh5.11.2) Transaction isolation: TRANSACTION_REPEATABLE_READ Beeline version 1.1.0-cdh5.11.2 by Apache Hive 0: jdbc:hive2://cdh-node-3:10000/default> 添加kylin权限将admin角色权限赋予kylin： 0: jdbc:hive2://cdh-node-3:10000/default> grant role admin to user kylin; INFO : Compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili INFO : Semantic Analysis Completed INFO : Returning Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8); Time taken: 0.069 seconds INFO : Executing command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8): grant role admin to user leili INFO : Starting task [Stage-0:DDL] in serial mode INFO : Completed executing command(queryId=hive_20180914174141_6359e1a1-251f-4116-b646-0aa9f55dcfa8); Time taken: 0.331 seconds INFO : OK No rows affected (0.528 seconds) 3.5 添加Hbase权限 使用拥有操作hbase权限的kerberos账户登录hbase shell： [root@cdh-node-3 hive]# hbase shell Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release 18/09/14 17:44:40 INFO Configuration.deprecation: hadoop.native.lib is deprecated.

KYLIN_HOME is set to /usr/local/apache-kylin-2.0.0-bin 3.7 启动kylin服务 先确认主机使用kerberos凭据为kylin，再启动： [root@cdh-node-2 bin]# klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: kylin@HWINFO.COM Valid starting Expires Service principal 09/14/2018 17:48:28 09/15/2018 17:48:28 krbtgt/HWINFO.COM@HWINFO.COM renew until 09/21/2018 17:48:28 [root@cdh-node-2 bin]# ./kylin.sh start Retrieving hadoop conf dir... KYLIN_HOME is set to /usr/local/kylin Retrieving hive dependency... Retrieving hbase dependency... Retrieving hadoop conf dir... Retrieving kafka dependency... Retrieving Spark dependency... KYLIN_JVM_SETTINGS is -Xms1024M -Xmx4096M -Xss1024K -XX:MaxPermSize=128M -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:/usr/local/kylin/logs/kylin.gc.3982 -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M A new Kylin instance is started by root. To stop it, run 'kylin.sh stop' Check the log at /usr/local/kylin/logs/kylin.log Web UI is at http://<hostname>:7070/kylin 4. 使用Kylin Sample测试 Kylin本身自带了一个测试例子，创建流程如下：执行sample.sh脚本，这个主要是创建kylin的project、model、cube以及相关的hive表等。 [root@cdh-node-2 bin]# ./sample.sh Retrieving hadoop conf dir... Retrieving hadoop conf dir... KYLIN_HOME is set to /usr/local/kylin Loading sample data into HDFS tmp path: /tmp/kylin/sample_cube/d ... Sample cube is created successfully in project 'learn_kylin'. Restart Kylin server or reload the metadata from web UI to see the change. 进入Kylin Web界面system - reload metadata然后构建示例的cube，如果构建成功，并且能成功执行查询命令，则表示整个配置全部完成。 [1] Cloudera Configuring Authentication Doc： https://www.cloudera.com/documentation/enterprise/5-11-x/topics/sg_authentication.html [2] Kylin官网配置指南： http://kylin.apache.org/cn/docs/install/configuration.html [3] Linux下的crontab定时执行任务命令详解： https://www.cnblogs.com/longjshz/p/5779215.html
