# docker run -d --name zookeeper -p 2181:2181 -v /etc/localtime:/etc/localtime  -e TZ=Asia/Shanghai  wurstmeister/zookeeper

[root@localhost Docker-Compose-Master]# mkdir zookeeper
[root@localhost Docker-Compose-Master]# ls
docker-compose.yml  kafka  zookeeper
[root@localhost Docker-Compose-Master]# cd zookeeper/
[root@localhost zookeeper]# ls
[root@localhost zookeeper]#
[root@localhost zookeeper]# docker run -d --name zookeeper -p 2181:2181 -v /etc/localtime:/etc/localtime  -e TZ=Asia/Shanghai  wurstmeister/zookeeper

======================================================================================
# 以上命令参数解释说明：

docker run：用于创建并启动一个新的容器

--name zookeeper：指定容器的名称为 "zookeeper"

-p 2181:2181：将主机的端口 2181 映射到容器的端口 2181，允许从主机上的其他应用程序访问 ZooKeeper 服务

-v /etc/localtime:/etc/localtime：将主机的系统时间配置文件挂载到容器内，以便容器内的时间与主机保持同步

-e TZ=Asia/Shanghai: 设置容器系统时区

wurstmeister/zookeeper：指定要使用的容器镜像

总结：
执行该命令后，Docker 将使用 wurstmeister/zookeeper 镜像创建一个名为 "zookeeper" 的容器。ZooKeeper 是一个开源的分布式协调服务，该容器提供了运行 ZooKeeper 服务器所需的环境。
通过将主机的端口 2181 映射到容器的端口 2181，可以轻松地访问在容器中运行的 ZooKeeper 服务。使用 -v 参数将主机的系统时间配置文件挂载到容器内，可以确保容器的时间与主机保持一致。
这条命令执行后，ZooKeeper 容器将在后台运行，并且您可以使用 docker ps 命令来查看正在运行的容器。

2. 安装Kafka

2.1 拉取kafka image

# 拉取kafka 镜像
# docker pull wuristmeister/kafka

[root@localhost kafka]# pwd
/home/magx/Docker-Compose-Master/kafka
[root@localhost kafka]#
[root@localhost kafka]# ll

======================================================================================
# 以上命令参数解释说明：

docker pull：用于从 Docker 镜像仓库中拉取（下载）一个镜像

wurstmeister/kafka：要拉取的镜像的名称

总结：
执行该命令后，Docker 将尝试从 Docker 镜像仓库中下载名为 wurstmeister/kafka 的镜像。这个镜像是由 wurstmeister 团队维护的 Kafka 镜像，Kafka 是一个流行的分布式流处理平台。

注意：
执行该命令需要在网络环境良好的情况下，并且 Docker 需要与 Docker 镜像仓库建立连接。下载完成后，可以使用 docker images 命令来查看已下载的镜像列表，确认 wurstmeister/kafka 镜像已成功下载

2.2 查询本地docker images

# 查询本地docker 镜像文件

2.5 启动kafka 镜像

2.5.0 挂在自定义配置文件

# 为避免后期修改kafka 容器配置文件，直接挂在配置文件
1）本地创建同名 配置文件 consumer.properties
2）修改配置文件中 bootstrap.server=
3) 执行 docker run -v ：


[root@localhost kafka]# pwd
/home/magx/Docker-Compose-Master/kafka
[root@localhost kafka]#
[root@localhost kafka]# ll
total 12
-rw-r--r--. 1 root root 1224 Dec 25 14:40 consumer.properties       # 本地同名配置文件
-rw-r--r--. 1 root root 3112 Dec  4 17:48 docker-compose-kafka.yml
drwxr-xr-x. 5 root root 4096 Dec  4 16:40 kafka-docker
[root@localhost kafka]#
[root@localhost kafka]#

2.5.1 启动kafaka container

#启动kakfa 容器

[root@localhost kafka]#
[root@localhost kafka]# docker run -d --name kafka  -v /etc/localtime:/etc/localtime:ro -p 9092:9092   -v /home/magx/Docker-Compose-Master/kafka/consumer.properties:/opt/kafka/config/consumer.properties -e TZ=Asia/Shanghai --link zookeeper:zookeeper --env KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 --env KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.2.247:9092 --env KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 --env KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1 wurstmeister/kafka
caac221a5a61b11a524f4c2601e02f300cb7229b69f4667d600c3827443be312
[root@localhost kafka]#
[root@localhost kafka]#



或者：
 docker run -d --name kafka  -v /etc/localtime:/etc/localtime:ro -p 9092:9092  -e TZ=Asia/Shanghai --link zookeeper:zookeeper --env KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 --env KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092 --env KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 --env KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1 wurstmeister/kafka



======================================================================================

通过以上命令，我们链接了ZooKeeper容器，并且设置了几个环境变量来配置Kafka。

在这个命令中：

--name kafka: 设置容器的名字为“kafka”。
-v /etc/localtime:/etc/localtime:ro 文件挂载到容器内的相应位置。这将使容器内部的时间与主机系统时间保持一致;
ro选项将/etc/localtime文件挂载为只读模式，以防止容器内部意外修改主机系统时间

 -v /home/magx/Docker-Compose-Master/kafka/consumer.properties:/opt/kafka/config/consumer.properties
本地同名文件所在目录 ： 容器中挂在目录

-p 9092:9092: 将容器的9092端口映射到宿主机的9092端口。

-e TZ=Asia/Shanghai: 设置容器系统时区

--link zookeeper:zookeeper: 连接到名为“zookeeper”的另一个Docker容器，并且在当前的容器中可以通过zookeeper这个别名来访问它。

--env KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181: 设置环境变量，指定ZooKeeper的连接字符串。

--env KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092: 设置环境变量，指定Kafka的advertised listeners。

--env KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092: 设置环境变量，指定Kafka的listeners。

--env KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1: 设置环境变量，指定offsets topic的副本因子。

wurstmeister/kafka: 使用的Docker镜像名字

确保在运行这个命令之前ZooKeeper容器已经在运行，并且可以通过zookeeper:2181来访问。
如果你的ZooKeeper容器有一个不同的名字或者你使用的是不同的网络设置，需要相应地调整--link和KAFKA_ZOOKEEPER_CONNECT的值

2.6 创建测试主题

2.6.1 进入kafka容器

# 进入kafka容器
#  docker exec -it kafka /bin/bash

[root@localhost kafka]#
[root@localhost kafka]# docker exec -it kafka /bin/bash
root@b03ba55d79cb:/#
root@b03ba55d79cb:/#

2.6.2 创建topic

# 在Kafka容器中，运行以下命令创建一个测试主题
# 进入kafka 容器后，创建topic

# kafka-topics.sh --create --topic  --partitions 1 --replication-factor 1 --zookeeper zookeeper:2181


[root@localhost kafka]# docker exec -it kafka /bin/bash            # 进入kafka 容器
root@b03ba55d79cb:/#
root@b03ba55d79cb:/# kafka-topics.sh --create --topic test1221 --partitions 1 --replication-factor 1 --zookeeper zookeeper:2181                    # 创建 topic
Created topic test1221.
root@b03ba55d79cb:/#



注意： 如果topic 包含 . 或者 _ 时，在执行创建topic过程中，会出现一个警告信息，提示主题名称中句点和下划线的使用限制。最后，命令成功执行并显示创建主题的结果

root@b03ba55d79cb:/# kafka-topics.sh --create --topic "alarm_warning" --partitions 1 --replication-factor 1 --zookeeper zookeeper:2181
WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic alarm_warning.
root@b03ba55d79cb:/#

注意：
在执行命令之后，出现了一个警告信息，提示由于指标名称的限制，主题名称中的句点('.')或下划线('_')可能会发生冲突。为了避免问题，最好只使用其中一种符号，而不是同时使用

2.6.3 查询已创建的topic

# 查询已创建的所有topic

[root@localhost grafana_loki_vector]# docker exec -it kafka /bin/bash   # 进入容器

# 在创建的主题中，生产kafka 消息
# kafka-console-producer.sh --broker-list localhost:9092 --topic 

[root@localhost kafka]# docker exec -it kafka /bin/bash

2.6.5 kafka 消费者消费消息

在另一个终端窗口中后，操作如下：
1）需要先进入kakfa 容器
# docker exec -it kafka /bin/bash

2）打开一个消费者来读取测试主题的消息
#kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic  --from-beginning

--from-beginning 为可选参数： 每次消费 该主题所有消息
不带 --from-beginning  参数： 每次仅仅消费启动kafka 消费者后，该主题最新的消息

ex: kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic  

注意： kafka 消费者消费消息之前要先进入 kafka 容器
======================================================================================

[root@localhost ~]#
[root@localhost ~]# docker exec -it kafka /bin/bash       #进入kafka 容器
root@b03ba55d79cb:/#
root@b03ba55d79cb:/# kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test1221 --from-beginning

docker 部署kafka

到此，基本完成使用Docker运行ZooKeeper和Kafka，并进行基本验证的过程。

3 安装完kafka 容器后，修改docker 中kafka 容器配置文件

3.1 进入kafka 容器

# 进入kafka 容器
# docker exec -it   /bin/bash

[root@localhost ~]# docker exec -it kafka /bin/bash
root@b03ba55d79cb:/#

3.2 修改配置文件

3.2.1 安装 vim

############################# Server Basics #############################

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=-1

############################# Socket Server Settings #############################

# The address the socket server listens on. It will get the value returned from
# java.net.InetAddress.getCanonicalHostName() if not configured.
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
# listeners=PLAINTEXT://0.0.0.0:9092
listeners=PLAINTEXT://192.168.2.247:9092

# Hostname and port the broker will advertise to producers and consumers. If not set,
# it uses the value for "listeners" if configured. Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
#advertised.listeners=PLAINTEXT://localhost:9092
advertised.listeners=PLAINTEXT://192.168.2.247:9092 #//your_ip_address:9092
# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

socket.receive.buffer.bytes=102400

# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600

############################# Log Basics #############################

# A comma separated list of directories under which to store log files
log.dirs=/kafka/kafka-logs-b03ba55d79cb

# The default number of log partitions per topic. More partitions allow greater
# parallelism for consumption, but this will also result in more files across
# the brokers.
num.partitions=1

# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
# This value is recommended to be increased for installations with data dirs located in RAID array.
num.recovery.threads.per.data.dir=1

############################# Internal Topic Settings #############################
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state"
# For anything other than development testing, a value greater than 1 is recommended to ensure availability such as 3.
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1

############################# Log Flush Policy #############################

# Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
# 1. Durability: Unflushed data may be lost if you are not using replication.
# 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
# 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.

# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000

# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000

############################# Log Retention Policy #############################

# The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.

# The minimum age of a log file to be eligible for deletion due to age
log.retention.hours=168

# A size-based retention policy for logs. Segments are pruned from the log unless the remaining
# segments drop below log.retention.bytes. Functions independently of log.retention.hours.
#log.retention.bytes=1073741824

# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000

############################# Zookeeper #############################

# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
zookeeper.connect=zookeeper:2181

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=18000

############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms=0

port=9092

注意：修改kafka 配置文件后，重启kafka 服务即可生效。

若重启kafka 容器（比如：docker start/restart ）会自动调用生成kafka 容器时命令（docker run -d –name kafka -p 9092:9092 –link zookeeper:zookeeper –env KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 –env KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://localhost:9092 –env KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 –env KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR=1 wurstmeister/kafka ）

故，若第一次创建容器时配置写错，即便进入容器修改配置文件，只要执行 docker start / restart 的命令，容器配置文件会再次恢复，修改配置不生效。

以上有效解决放法，删除容器，重新创建，具体操作 3.3 修改配置，重启重建容器

重启容器中kafka 服务，配置更改生效，为避免已后麻烦，最好直接删除容器，修改配置参数，重建容器

以上有效解决放法，删除容器，重新创建，具体操作 3.3 修改配置，重启重建容器

3.3 重启重建容器

3.3.1 停止运行的kafka 容器

# 修改配置文件后，重启kafka 容器后，再次查看配置文件，修改没有保存，为此，删除kafka 缓存

3.3.3 删除Kafka数据目录

删除Kafka数据目录：Kafka存储数据的目录通常位于容器内部的/var/lib/kafka路径。删除该目录以清除Kafka的数据缓存。注意，删除数据目录将导致所有Kafka数据的丢失，包括主题、消费者偏移量等

root@b03ba55d79cb:/# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime  
root@b03ba55d79cb:/#
root@b03ba55d79cb:/# date                               # 设置之后，kafka container 时间
Fri Dec 22 17:08:13 CST 2023
root@b03ba55d79cb:/#
root@b03ba55d79cb:/# exit
exit
[root@localhost ~]#
[root@localhost ~]# date                                # 设置之后，主机时间
Fri Dec 22 17:08:18 CST 2023
[root@localhost ~]#



注意：
为了避免后期设置时间同步问题，在创建 容器时添加 参数  保证容器与主机时间一致
-v /etc/localtime:/etc/localtime:ro 

ro选项将/etc/localtime文件挂载为只读模式，以防止容器内部意外修改主机系统时间

至此，已结束kafka 部署

5. 远程连接kafka 容器失败原因定位

因远程连接kafka 容器失败，曾多次频繁删除kafka 容器，导致kafka 容器内生产者生产的消息，消费者接收不到。

5.1 删除zookeeper 容器

[root@localhost kafka]# docker stop zookeeper
zookeeper
[root@localhost kafka]#
[root@localhost kafka]#
[root@localhost kafka]#
[root@localhost kafka]# docker ps -a
