Sqoop2开启Kerberos安全模式,
基于版本sqoop-1.99.7,
在已经安装好的sqoop2环境上配置kerberos。
1.安装规划
10.43.159.9 zdh-9
sqoop2krb/zdh1234
10.43.159.11 zdh-11
kerberos server
2.创建keytab
在zdh-11上,登陆root用户在/root/keytabs目录下,
创建sqoop2krb和HTTP的principal,并导出到sqoop.keytab:
kadmin.local addprinc -randkey HTTP/zdh-9@ZDH.COM addprinc -randkey sqoop/zdh-9@ZDH.COM xst -k HTTPzdh9.keytab HTTP/zdh-9@ZDH.COM xst -k sqoopzdh9.keytab sqoop/zdh-9@ZDH.COM exit
3.分发keytab
将sqoop.keytab复制到sqoop2krb相应目录下:
scp HTTPzdh9.keytab sqoop2krb@zdh-9:/home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs
scp sqoopzdh9.keytab sqoop2krb@zdh-9:/home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs
修改为用户只读权限:
chmod 400 HTTPzdh9.keytab
chmod 400 sqoopzdh9.keytab
需要kinit初始化principal,否则sqoop2无法启动:
kinit -kt HTTPzdh9.keytab HTTP/zdh-9@ZDH.COM
kinit -kt sqoopzdh9.keytab sqoop/zdh-9@ZDH.COM
4.修改配置文件
登陆sqoop2krb,修改conf/sqoop.properties文件:
org.apache.sqoop.security.authentication.type=KERBEROS org.apache.sqoop.security.authentication.handler=org.apache.sqoop.security.authentication.KerberosAuthenticationHandler org.apache.sqoop.security.authentication.kerberos.principal=sqoop/_HOST@ZDH.COM org.apache.sqoop.security.authentication.kerberos.keytab=/home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs/sqoopzdh9.keytab org.apache.sqoop.security.authentication.kerberos.http.principal=HTTP/_HOST@ZDH.COM org.apache.sqoop.security.authentication.kerberos.http.keytab=/home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs/HTTPzdh9.keytab org.apache.sqoop.security.authentication.enable.doAs=true
注意:sqoop/_HOST@ZDH.COM中的_HOST不用修改,运行时会自动改为sqoop/zdh-9@ZDH.COM之类的。
5.配置环境变量
export SQOOP2_HOST=$(hostname -f)
SQOOP2_HOST(zdh-9)的值会被用来替换上面_HOST
6.启动sqoop2
sqoop2-server start
停止sqoop2:
sqoop2-server stop
启动成功并且开启kerberos可以在sqoop.log看到如下日志:
2018-03-09 10:35:12,376 INFO [org.apache.sqoop.security.authentication.KerberosAuthenticationHandler.secureLogin(KerberosAuthenticationHandler.] Using Kerberos authentication, principal [sqoop/_HOST@ZDH.COM] keytab [/home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs/sqoopzdh9.keytab]2018-03-09 10:35:16,744 INFO [org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler.init(KerberosAuthenticationHandler.] Login using keytab /home/sqoop2krb/sqoop-1.99.7-bin-hadoop200/keytabs/HTTPzdh9.keytab, for principal HTTP/zdh-9@ZDH.COM
7.客户端验证
先初始化凭据:
kinit -kt sqoopzdh9.keytab sqoop/zdh-9@ZDH.COM
客户端登陆:
sqoop2-shell
展示所有的connector:
show connector
sqoop2客户端执行命令时,会使用sqoop作为用户去sqoop2服务查询,
如果kinit -kt HTTPzdh9.keytab HTTP/zdh-9@ZDH.COM,
则会用HTTP用户作为请求的用户,即会使用最近一次的kinit的用户作为
登陆用户去服务端查询结果。
查询结果正确,且可以在sqoop.log看到如下日志:
2018-03-09 10:46:08,377 INFO [org.apache.sqoop.audit.FileAuditLogger.logAuditEvent(FileAuditLogger.] user=sqoop ip=10.43.159.9 op=get obj=connectors objId=all
8.Rest服务验证
其他服务通过HTTP请求访问rest接口,
比如RangerAdmin使用rangerlookup用户进行testConnection测试,
测试连接成功可以在sqoop.log看到如下日志:
2018-03-09 10:49:13,085 INFO [org.apache.sqoop.audit.FileAuditLogger.logAuditEvent(Fil
