前言

测试服务器：10.255.60.149

一. 编写docker-compose文件

1.docker-compose.yml

version: '3.8'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    volumes:
       - /data/zookeeper/data:/data
       - /home/docker-compose/kafka/config:/opt/zookeeper-3.4.13/conf/
       - /home/docker-compose/kafka/config:/opt/zookeeper-3.4.13/secrets/ 
    container_name: zookeeper
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
      SERVER_JVMFLAGS: -Djava.security.auth.login.config=/opt/zookeeper-3.4.13/secrets/server_jaas.conf
    ports:
      - 12181:2181
    restart: always
  kafka_node1:
    image: wurstmeister/kafka
    container_name: kafka_node1
    depends_on:
      - zookeeper
    ports: 
      - 9092:9092
    volumes:
      - /home/docker-compose/kafka/data:/kafka
      - /home/docker-compose/kafka/config:/opt/kafka/secrets/
    environment:
      KAFKA_BROKER_ID: 0
      KAFKA_ADVERTISED_LISTENERS: SASL_PLAINTEXT://10.255.60.149:9092
      KAFKA_ADVERTISED_PORT: 9092 
      KAFKA_LISTENERS: SASL_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: zookeeper: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
 ##  kafdrop 监控kafka的Ui工具 
  kafdrop:
    image: obsidiandynamics/kafdrop
    restart: always
    ports:
       - "19001:9000"
    environment:
       KAFKA_BROKERCONNECT: "kafka_node1:9092"
    ## 如kafka开启了sasl认证后以下 sasl认证链接是必要的，下面的事经过base64加密后的结果
       KAFKA_PROPERTIES: c2FzbC5tZWNoYW5pc206IFBMQUlOCiAgICAgIHNlY3VyaXR5LnByb3RvY29sOiBTQVNMX1BMQUlOVEVYVAogICAgICBzYXNsLmphYXMuY29uZmlnOiBvcmcuYXBhY2hlLmthZmthLmNvbW1vbi5zZWN1cml0eS5zY3JhbS5TY3JhbUxvZ2luTW9kdWxlIHJlcXVpcmVkIHVzZXJuYW1lPSdhZG1pbicgcGFzc3dvcmQ9J2pkeXgjcXdlMTInOw==
    depends_on:
      - zookeeper
      - kafka_node1
    cpus: '1'
    mem_limit: 1024m
    container_name: kafdrop
    restart: always

把此文件放入/home/docker-compose目录下，文件夹可自定义，不过要注意修改yml文件中的挂载位置

其中KAFKA_PROPERTIES使用base64解密后内容如下

sasl.mechanism: PLAIN
      security.protocol: SASL_PLAINTEXT
      sasl.jaas.config: org.apache.kafka.common.security.scram.ScramLoginModule required username='admin' password='jdyx#qwe12';

对文件内容进行base64加密方式为

base64 file
或者
cat file | base64

二.添加配置文件

在宿主机新建目录/home/docker-compose/kafka/config，然后新增下面配置文件

其中log4j.properties和configuration.xsl 可以使用docker cp 命令 从zookeeper容器copy出来的，文件没变化

1. server_jaas.conf
Client {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="admin"
    password="jdyx#qwe12";
}; 
Server {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="admin"
    password="jdyx#qwe12"
    ## user_用户名="密码" 这种格式是用来配置账号跟密码的
    user_super="jdyx#qwe12"
    user_admin="jdyx#qwe12";
};
KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="jdyx#qwe12"  
  ## user_用户名="密码"  这种格式是用来配置账号跟密码的
    user_admin="jdyx#qwe12";
};

KafkaClient {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="jdyx#qwe12";
};
2. zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/opt/zookeeper-3.4.13/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1

## 开启SASl关键配置
authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider

requireClientAuthScheme=sasl

jaasLoginRenew=3600000
zookeeper.sasl.client=true
3. configuration.xsl

<xsl:template match="configuration">

# Example with rolling log file
#log4j.rootLogger=DEBUG, CONSOLE, ROLLINGFILE

# Example with rolling log file and tracing

log4j.appender.TRACEFILE=org.apache.log4j.FileAppender
log4j.appender.TRACEFILE.Threshold=TRACE
log4j.appender.TRACEFILE.File=${zookeeper.tracelog.dir}/${zookeeper.tracelog.file}

log4j.appender.TRACEFILE.layout=org.apache.log4j.PatternLayout

log4j.appender.TRACEFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L][%x] - %m%n

三. 搭建与测试

执行docker-compse up -d，正常情况下容器可成功运行，多查看日志排查下

编写kafkacat.conf

security.protocol=SASL_PLAINTEXT
sasl.mechanisms=PLAIN
sasl.username=admin
sasl.password=jdyx#qwe12

安装kafkacat

ubuntu安装：apt install kafkacat
centos安装：参考https://blog.51cto.com/u_15067222/4321386

测试命令

echo '{"data":[{"value":"00002192","type":2,"id":300011},{"value":"00000D7
A","type":2,"id":300009}],"plcId":0,"endTime":1571894892,"startTime":157189 1260,"tag":28690}' | kafkacat -b 10.255.60.149:9092 -t device-data -P -F ./kafkacat.conf

kafkacat -C -b 10.255.60.149:9092 -t device-data -F ./kafkacat.conf
