SASL/SCRAM+ACL实现动态创建用户及权限控制

本篇文档中使用的是自己部署的zookeeper, zookeeper无需做任何特殊配置

使用SASL / SCRAM进行身份验证

请先在不配置任何身份验证的情况下启动Kafka

1. 创建SCRAM Credentials

Kafka中的SCRAM实现使用Zookeeper作为凭证(credential)存储。可以使用kafka-configs.sh在Zookeeper中创建凭据。对于启用的每个SCRAM机制，必须通过添加具有机制名称的配置来创建凭证。必须在启动Kafka broker之前创建代理间通信的凭据。可以动态创建和更新客户端凭证，并使用更新的凭证来验证新连接。

创建broker建通信用户(或称超级用户)

bin/kafka-configs.sh --zookeeper node1:2181 --alter --add-config 'SCRAM-SHA-256=[password=admin-secret],SCRAM-SHA-512=[password=admin-secret]' --entity-type users --entity-name admin

创建客户端用户fanboshi

bin/kafka-configs.sh --zookeeper node1:2181 --alter --add-config 'SCRAM-SHA-256=[iterations=8192,password=fanboshi],SCRAM-SHA-512=[password=fanboshi]' --entity-type users --entity-name fanboshi

查看SCRAM证书

[root@node002229 kafka]# bin/kafka-configs.sh --zookeeper node1:2181 --describe --entity-type users --entity-name fanboshi
Configs for user-principal 'fanboshi' are SCRAM-SHA-512=salt=MWwwdWJqcjBncmUwdzY1Mzdoa2NwNXppd3A=,stored_key=mGCJy5k3LrE2gs6Dp4ALRhgy37l1WYPUIdoOncCF+B3Ti3wL2sQNmzg8oEz3tUs9DFsclFCygjbysb0S0BU9bA==,server_key=iTyX0U0Jt02dkddUm6QrVwNf3lJk72dBNs9EDHTqe8kLlNGIp9ypzRkcgkc+WVMd1bkAF3cg8vk9Q1LrJ/2i/A==,iterations=4096,SCRAM-SHA-256=salt=ZDg5MHVlYW40dW9jbXJ6MndvZDVlazd3ag==,stored_key=cgX1ldpXnDL1+TlLHJ3IHn7tAQS/7pQ7BVZUtECpQ3A=,server_key=i7Mcnb5sPUqfIFs6qKWWHZ2ortoKiRc7oabHOV5dawI=,iterations=8192

删除SCRAM证书

这里只演示,不操作

[root@node002229 kafka]# bin/kafka-configs.sh --zookeeper node1:2181 --alter  --delete-config 'SCRAM-SHA-512' --entity-type users --entity-name fanboshi

2. 配置Kafka Brokers

在每个Kafka broker的config目录中添加一个类似下面的JAAS文件，我们称之为kafka_server_jaas.conf：

[root@node002229 config]# cat kafka_server_jaas.conf
KafkaServer {
  org.apache.kafka.common.security.scram.ScramLoginModule required
  username="admin"
  password="admin-secret";
};

注意不要少写了分号

将JAAS配置文件位置作为JVM参数传递给每个Kafka broker：
修改 /usr/local/kafka/bin/kafka-server-start.sh
将exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@" 注释, 增加下面的内容

#exec $base_dir/kafka-run-class.sh $EXTRA_ARGS kafka.Kafka "$@"
exec $base_dir/kafka-run-class.sh $EXTRA_ARGS -Djava.security.auth.login.config=$base_dir/../config/kafka_server_jaas.conf kafka.Kafka "$@"

或者不修改kafka-server-start.sh脚本, 而是将下面的内容添加到~/.bashrc

export KAFKA_PLAIN_PARAMS="-Djava.security.auth.login.config=/usr/local/kafka/config/kafka_server_jaas.conf"
export KAFKA_OPTS="$KAFKA_PLAIN_PARAMS $KAFKA_OPTS"

如此处所述，在server.properties中配置SASL端口和SASL机制。例如：

# 认证配置
listeners=SASL_PLAINTEXT://node002229:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.mechanism.inter.broker.protocol=SCRAM-SHA-256
sasl.enabled.mechanisms=SCRAM-SHA-256

# ACL配置
allow.everyone.if.no.acl.found=false
super.users=User:admin
authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

再官方文档中写的是

listeners=SASL_SSL://host.name:port
security.inter.broker.protocol=SASL_SSL

这里其实没必要写成SASL_SSL , 我们可以根据自己的需求选择SSL或PLAINTEXT, 我这里选择PLAINTEXT不加密明文传输, 省事, 性能也相对好一些

重启ZK/Kafka
重启ZK / Kafka服务. 所有broker在连接之前都会引用'kafka_server_jaas.conf'.
Zookeeper所有节点

[root@node002229 zookeeper]# zkServer.sh stop /usr/local/zookeeper/bin/../conf/zoo.cfg  
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo1.cfg
Stopping zookeeper ... STOPPED

[root@node002229 zookeeper]# zkServer.sh start /usr/local/zookeeper/bin/../conf/zoo.cfg  
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo1.cfg

Kafka所有Broker

cd /usr/local/kafka/;bin/kafka-server-stop.sh
cd /usr/local/kafka/;bin/kafka-server-start.sh -daemon config/server.properties

客户端配置

先使用kafka-console-producer 和 kafka-console-consumer 测试一下

kafka-console-producer

创建 config/client-sasl.properties 文件

[root@node002229 kafka]# vim config/client-sasl.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256

创建config/kafka_client_jaas_admin.conf文件

[root@node002229 kafka]# vim config/kafka_client_jaas_admin.conf 
KafkaClient {
  org.apache.kafka.common.security.scram.ScramLoginModule required
  username="admin"
  password="admin-secret";
};

修改kafka-console-producer.sh脚本
这里我复制一份,再改

cp bin/kafka-console-producer.sh bin/kafka-console-producer-admin.sh
vim bin/kafka-console-producer-admin.sh
#exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleProducer "$@"
exec $(dirname $0)/kafka-run-class.sh -Djava.security.auth.login.config=$(dirname $0)/../config/kafka_client_jaas_admin.conf kafka.tools.ConsoleProducer "$@"

创建测试topic

bin/kafka-topics.sh --create --zookeeper node1:2181 --partitions 1 --replication-factor 1 --topic test

测试生产消息

bin/kafka-console-producer-admin.sh --broker-list node1:9092 --topic test --producer.config config/client-sasl.properties
>1
>

可以看到admin用户无需配置ACL就可以生成消息

测试fanboshi用户
如法炮制, 我们创建一个bin/kafka-console-producer-fanboshi.sh文件, 只是修改其中的kafka_client_jaas_admin.conf 为 kafka_client_jaas_fanboshi.conf

vim config/kafka_client_jaas_fanboshi.conf 
KafkaClient {
  org.apache.kafka.common.security.scram.ScramLoginModule required
  username="fanboshi"
  password="fanboshi";
};

cp bin/kafka-console-producer-admin.sh bin/kafka-console-producer-fanboshi.sh
vi bin/kafka-console-producer-fanboshi.sh
exec $(dirname $0)/kafka-run-class.sh -Djava.security.auth.login.config=$(dirname $0)/../config/kafka_client_jaas_fanboshi.conf kafka.tools.ConsoleProducer "$@"

生产消息

[root@node002229 kafka]# bin/kafka-console-producer-fanboshi.sh --broker-list node1:9092 --topic test --producer.config config/client-sasl.properties
>1
[2019-01-26 18:07:50,099] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 1 : {test=TOPIC_AUTHORIZATION_FAILED} (org.apache.kafka.clients.NetworkClient)
[2019-01-26 18:07:50,100] ERROR Error when sending message to topic test with key: null, value: 1 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TopicAuthorizationException: Not authorized to access topics: [test]

可以看到报错了, 因为fanboshi用户还没有权限

kafka-console-consumer

创建 config/consumer-fanboshi.properties 文件

[root@node002229 kafka]# vim config/consumer-fanboshi.properties
security.protocol=SASL_PLAINTEXT
sasl.mechanism=SCRAM-SHA-256
group.id=fanboshi-group

创建 bin/kafka-console-consumer-fanboshi.sh 文件

cp bin/kafka-console-consumer.sh bin/kafka-console-consumer-fanboshi.sh
vim bin/kafka-console-consumer-fanboshi.sh
#exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleConsumer "$@"
exec $(dirname $0)/kafka-run-class.sh -Djava.security.auth.login.config=$(dirname $0)/../config/kafka_client_jaas_fanboshi.conf kafka.tools.ConsoleConsumer "$@"

测试消费者

bin/kafka-console-consumer-fanboshi.sh --bootstrap-server node1:9092 --topic test --consumer.config config/consumer-fanboshi.properties --from-beginning

其实也会报错的, 报错内容就不贴了

ACL配置

授予fanboshi用户对test topic 写权限, 只允许 192.168.2.* 网段

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=node1:2181 --add --allow-principal User:fanboshi --operation Write --topic test --allow-host 192.168.2.*

授予fanboshi用户对test topic 读权限, 只允许 192.168.2.* 网段

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=node1:2181 --add --allow-principal User:fanboshi --operation Read --topic test --allow-host 192.168.2.*

授予fanboshi用户, fanboshi-group 消费者组对test topic 读权限, 只允许 192.168.2.* 网段

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=node1:2181 --add --allow-principal User:fanboshi --operation Read --group fanboshi-group --allow-host 192.168.2.*

查看acl配置

[root@node002229 kafka]# bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=node1:2181 --list
Current ACLs for resource `Group:LITERAL:fanboshi-group`: 
        User:fanboshi has Allow permission for operations: Read from hosts: * 

Current ACLs for resource `Topic:LITERAL:test`: 
        User:fanboshi has Allow permission for operations: Write from hosts: *
        User:fanboshi has Allow permission for operations: Read from hosts: *

删除配置

bin/kafka-acls.sh --authorizer kafka.security.auth.SimpleAclAuthorizer --authorizer-properties zookeeper.connect=node1:2181 --remove --allow-principal User:fanboshi  --operation Write --topic test --allow-host *

再次测试

生产者

[root@node002229 kafka]# bin/kafka-console-producer-fanboshi.sh --broker-list node1:9092 --topic test --producer.config config/client-sasl.properties
>1
[2019-01-26 18:07:50,099] WARN [Producer clientId=console-producer] Error while fetching metadata with correlation id 1 : {test=TOPIC_AUTHORIZATION_FAILED} (org.apache.kafka.clients.NetworkClient)
[2019-01-26 18:07:50,100] ERROR Error when sending message to topic test with key: null, value: 1 bytes with error: (org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TopicAuthorizationException: Not authorized to access topics: [test]
>1

消费者

[root@node002229 kafka]# bin/kafka-console-consumer-fanboshi.sh --bootstrap-server node1:9092 --topic test --consumer.config config/consumer-fanboshi.properties --from-beginning
1
1

都没问题了

如何查看我们创建了哪些"用户"

好像只能去zookeeper看?

zkCli.sh -server node1:2181
ls /config/users
[admin, alice, fanboshi]

尝试删除alice

[root@node002229 kafka]# bin/kafka-configs.sh --zookeeper node1:2181 --describe --entity-type users --entity-name alice
Configs for user-principal 'alice' are SCRAM-SHA-512=salt=MWt1OHRhZnd3cWZvZ2I4bXcwdTM0czIyaTQ=,stored_key=JYeud1Cx5Z2+FaJgJsZGbMcIi63B9XtA9Wyc+KEm2gXK8+2IxxAVvi1CfSjlkqeupfeIMFJ7/EUkOw+zqvYz6w==,server_key=O4NIgjleroia7puK01/ZZoagFeoxh+zHzckGXXooBsWTdx/7Shb0pMHniMu4IY2jb5orWB2t9K8MZkxCliJDsg==,iterations=4096,SCRAM-SHA-256=salt=MTJ3bXRod3EyN3FtZWdsNHk0NXoyeWdlNjE=,stored_key=chQX35reoBYtfg/U5HBtkzvBAk+gSCgskNzUiScOrUE=,server_key=rRTbUzAehwVMUDTMuoOMumGEuvc7wDecKcqK6yYlbWY=,iterations=8192

[root@node002229 kafka]# bin/kafka-configs.sh --zookeeper node1:2181 --describe --entity-type users --entity-name alice

Configs for user-principal 'alice' are

去ZK查看

[zk: node1:2181(CONNECTED) 0] ls /config/users
[admin, alice, fanboshi]

kafka ACL常用权限操作

创建topic

使用bin/kafka-topics.sh创建
注意工具bin/kafka-topics.sh访问的是zookeeper而不是kafka，即他是一个zookeeper client而不是一个kafka client，所以它的认证都是通过zookeeper完成的。
Case 1：如果zookeeper没有配置ACL激活：

/opt/kafka/bin/kafka-topics.sh --create \
  --zookeeper node1:2181 \
  --replication-factor 1 \
  --partitions 1 \
  --topic kafkaclient-topic

Case 2：如果zookeeper已经配置ACL激活：
命令还是前面的那个命令，但是必须提供java.security.auth.login.config指向jaas.conf文件。例如：

$ cat $ZOOKEEPER_HOME/conf/zookeeper_client_jaas_admin.conf 
Client {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="adminpwd";
};

命令的配置可以直接修改jvm的启动脚本，或者设置在环境变量里：

export KAFKA_OPTS=-Djava.security.auth.login.config=$ZOOKEEPER_HOME/conf/zookeeper_client_jaas_admin.conf

这里配置的用户必须是zookeeper服务端已经配置运行可以访问的客户端用户。例如，下面的zookeeper服务端配置：

$ cat $ZOOKEEPER_HOME/conf/zookeeper_jaas.conf 
Server {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="adminpwd"
    user_admin="adminpwd";
};

运行客户端为admin的用户作为zookeeper客户端连接访问。

查询topic

kafka-topics.sh --list --zookeeper node1:2181

查询topic操作的ACL认证，同前面创建topic操作的认证一样，不细说，参考前面。

删除topic

/kafka-topics.sh \
  --delete \
  --zookeeper node1:2181 \
  --topic kafkaclient-topic

删除topic操作的ACL认证，同前面创建topic操作的认证一样，不细说，参考前面。
