Kafka集群部署（docker容器方式）SASL认证（zookeeper)

一、服务器环境

序号	部署版本	版本
1	操作系统	CentOS Linux release 7.9.2009 (Core)
2	docker	Docker version 20.10.6
3	docker-compose	docker-compose version 1.28.2

 二、服务规划

序号	服务	名称	端口
1	zookeeper	zookeeper	2181,2888,3888
2	kafka	kafka	9092:9092

 三、部署kafka

1、创建/opt/beidousky/kafka-zk目录，添加docker-compose.yaml文件

version: "3"
services:
  zookeeper-sasl:
    image: zookeeper:3.6.3
    container_name: zookeeper-sasl
    user: root
    restart: always
    ports:
      - 2181:2181
      - 2888:2888
      - 3888:3888
    environment:
      ZOO_MY_ID: 1
      TZ: Asia/Shanghai
    volumes:
      - ./zk-conf/zoo.cfg:/conf/zoo.cfg
      - ./zk-conf/zookeeper_server_jaas.conf:/conf/zookeeper_server_jaas.conf
      - ./zk-conf/java.env:/conf/java.env
      - ./zk-data/data:/data
      - ./zk-data/datalog:/datalog
      - ./zk-data/logs:/logs
  kafka:
    image: wurstmeister/kafka:2.13-2.8.1
    container_name: kafka
    depends_on:
      - zookeeper-sasl
    ports:
      - 9092:9092
    volumes:
      - ./kafka-data:/kafka
      - ./kafka-conf:/opt/kafka/secrets/
    environment:
      KAFKA_BROKER_ID: 0
      KAFKA_ADVERTISED_PORT: 9092
     #KAFKA_ADVERTISED_LISTENERS: SASL_PLAINTEXT://192.168.1.244:9092
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://192.168.1.244:9092
     #KAFKA_LISTENERS: SASL_PLAINTEXT://0.0.0.0:9092
      KAFKA_LISTENERS: PLAINTEXT://0.0.0.0:9092
     #KAFKA_SECURITY_INTER_BROKER_PROTOCOL: SASL_PLAINTEXT
      KAFKA_PORT: 9092
     #KAFKA_SASL_MECHANISM_INTER_BROKER_PROTOCOL: PLAIN
     #KAFKA_SASL_ENABLED_MECHANISMS: PLAIN
     #KAFKA_AUTHORIZER_CLASS_NAME: kafka.security.auth.SimpleAclAuthorizer
     #KAFKA_SUPER_USERS: User:admin
      KAFKA_ALLOW_EVERYONE_IF_NO_ACL_FOUND: "true" #设置为true，ACL机制为黑名单机制，只有黑名单中的用户无法访问，默认为false，ACL机制为白名单机制
，只有白名单中的用户可以访问
      KAFKA_ZOOKEEPER_CONNECT: 192.168.1.244:2181
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
      KAFKA_GROUP_INITIAL_REBALANCE_DELAY_MS: 0
      KAFKA_HEAP_OPTS: "-Xmx512M -Xms16M"
      KAFKA_OPTS: -Djava.security.auth.login.config=/opt/kafka/secrets/server_jaas.conf  
    restart: always

2、创建/opt/beidousky/kafka-zk/zk-conf目录，添加zoo.cfg文件

dataDir=/data
dataLogDir=/datalog
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=true
quorumListenOnAllIPs=true

server.1=192.168.1.244:2888:3888;2181
#server.2=192.168.1.xxx:2888:3888;2181
#server.3=192.168.1.xxx:3888;2181

authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider
sessionRequireClientSASLAuth=true
#requireClientAuthScheme=sasl
jaasLoginRenew=3600000

3、在/opt/beidousky/kafka-zk/zk-conf目录下，添加java.env文件

# 指定jaas文件的位置
SERVER_JVMFLAGS="-Djava.security.auth.login.config=/conf/zookeeper_server_jaas.conf"

4、在/opt/beidousky/kafka-zk/zk-conf目录下，添加zookeeper_server_jaas.conf文件

数据格式为user_用户名="用户密码"或者username="用户名" password="用户密码"

Server {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       user_admin="admin123"
       user_kafka="kafka123"
       ;
};

Client {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       username="kafka"
       password="kafka123"
       ;
};

5、创建/opt/beidousky/kafka-zk/kafka-conf目录，添加server_jaas.conf文件

Server {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       user_admin="admin123"
       user_kafka="kafka123"
       ;
};

Client {
       org.apache.zookeeper.server.auth.DigestLoginModule required
       username="kafka"
       password="kafka123"
       ;
};

6、启动kafka服务

cd /opt/server/kafka-zk
docker-compose up -d
