今天的博客介绍大数据安全系列之flink的kerberos配置

一、flink安装

1、解压安装包

tar -zxvf flink-1.8.0-bin-scala_2.11.tgz -C /usr/local/

2、重命名安装目录

[root@cluster2-host1 local]# mv flink-1.8.0/ flink

3、修改环境变量文件

export FLINK_HOME=/usr/local/flink  export PATH=${PATH}:${FLINK_HOME}/bin

[root@cluster2-host1 data]# source /etc/profile

[root@cluster2-host1 data]# echo $FLINK_HOME

/usr/local/flink

4、修改flink的配置文件

[root@cluster2-host1 conf]# vim flink-conf.yaml  [root@cluster2-host1 conf]# pwd  /usr/local/flink/conf

jobmanager.rpc.address: cluster2-host1

修改slaver文件

[root@cluster2-host1 conf]# vim slaves  [root@cluster2-host1 conf]# pwd  /usr/local/flink/conf

cluster2-host2  cluster2-host3

修改master文件

[root@cluster2-host1 bin]# cat /usr/local/flink/conf/masters  cluster2-host1

修改yarn-site.xml文件

<property>    <name>yarn.nodemanager.vmem-pmem-ratio</name>    <value>5</value>  </property>

5、创建flink用户

[root@cluster2-host3 hadoop]# useradd flink -g flink  [root@cluster2-host3 hadoop]# passwd flink  Changing password for user flink.  New password:  BAD PASSWORD: The password fails the dictionary check - it is based on a dictionary word  Retype new password:

6、修改flink安装目录的属主和属组

[root@cluster2-host3 hadoop]# chown -R flink:flink /usr/local/flink/

7、启动flink验证安装步骤

[root@cluster2-host1 bin]# ./start-cluster.sh  Starting cluster.  [INFO] 1 instance(s) of standalonesession are already running on cluster2-host1.  Starting standalonesession daemon on host cluster2-host1.  Starting taskexecutor daemon on host cluster2-host2.  Starting taskexecutor daemon on host cluster2-host3.

检查进程

[root@cluster2-host1 bin]# jps  10400 Secur  30817 StandaloneSessionClusterEntrypoint  12661 ResourceManager  12805 NodeManager  4998 QuorumPeerMain  30935 Jps  2631 NameNode

关闭flink，上面的standalone的启动方法，下面启动flink-session模式

拷贝hadoop的依赖包到flink的lib目录

scp flink-shaded-hadoop2-uber-2.7.5-1.8.0.jar /usr/local/flink/lib/

启动flink-session模式

 ./yarn-session.sh -n 2 -s 6 -jm 1024 -tm 1024 -nm test -d

二、配置flink的kerberos的配置

1、创建flink的kerberos认证主体文件

kadmin.local:  addprinc flink/cluster2-host1  kadmin.local:  addprinc flink/cluster2-host2  kadmin.local:  addprinc flink/cluster2-host3

kadmin.local:  ktadd -norandkey -k /etc/security/keytab/flink.keytab flink/cluster2-host1  kadmin.local:  ktadd -norandkey -k /etc/security/keytab/flink.keytab flink/cluster2-host2  kadmin.local:  ktadd -norandkey -k /etc/security/keytab/flink.keytab flink/cluster2-host3

2、拷贝keytab文件到其它节点

[root@cluster2-host1 bin]# scp /etc/security/keytab/flink.keytab root@cluster2-host2:/usr/local/flink/  flink.keytab                                                                                                                                                                                                                                100% 1580     1.5KB/s   00:00  [root@cluster2-host1 bin]# scp /etc/security/keytab/flink.keytab root@cluster2-host3:/usr/local/flink/  flink.keytab

3、修改flink的配置文件

security.kerberos.login.use-ticket-cache: true  security.kerberos.login.keytab: /usr/local/flink/flink.keytab  security.kerberos.login.principal: flink/cluster2-host3  yarn.log-aggregation-enable: true

4、启动yarn-session，看到如下操作，则配置完成

flink@cluster2-host1 bin]$  ./yarn-session.sh -n 2 -s 6 -jm 1024 -tm 1024 -nm flink5 -d    2020-03-05 02:42:23,706 INFO  org.apache.hadoop.security.UserGroupInformation               - Login successful for user flink/cluster2-host1 using keytab file /usr/local/flink/flink.keytab
