提供者：MappleZF

版本：1.0.0

一、部署zookeeper

1.1 准备环境

准备安装包、安装jdk

1.2 安装解压

tar xf apache-zookeeper-3.6.2-bin.tar.gz -C /opt/
cd /opt && mv apache-zookeeper-3.6.2-bin/ zookeeper
mkdir /opt/zookeeper/{data,logs}

1.3 添加DNS域名解析或修改hosts文件

[[email protected]:/root]# vim /var/named/lowan.com.zone
zk01            A       192.168.13.101
zk02            A       192.168.13.102
zk03            A       192.168.13.103

1.4 配置zoo.cfg文件

cd /opt/zookeeper/conf/
cp -p zoo_sample.cfg zoo.cfg

conf]# vim zoo.cfg
内容如下：
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/logs
clientPort=2181
server.1=192.168.13.101:2888:3888
server.2=192.168.13.102:2888:3888
server.3=192.168.13.103:2888:3888
autopurge.purgeInterval=12
max_session_timeout=40000
min_session_timeout=4000

分发cfg文件
scp zoo.cfg k8smaster02:/opt/zookeeper/conf/
scp zoo.cfg k8smaster03:/opt/zookeeper/conf/

1.5 创建myid文件

# 每个服务器上的myid内容都不同，且需要保证和自己的zoo.cfg配置文件中"server.id=host:port:port"的id值一致
# id的范围是1~255

[[email protected]:/opt/zookeeper/conf]# echo "1" > /opt/zookeeper/data/myid
[[email protected]:/opt]# echo "2" > /opt/zookeeper/data/myid
[[email protected]:/opt]# echo "3" > /opt/zookeeper/data/myid

1.6 启动zookeeper

/opt/zookeeper/bin/zkServer.sh start
ps -ef | grep zookeeper

1.7 添加守护进程

vim /etc/systemd/system/zookeeper.service

[Unit]
Description=zookeeper server
Requires=network.target remote-fs.target
After=network.target remote-fs.target

[Service]
Type=forking
User=root
Environment=JAVA_HOME=/usr/local/java
ExecStart=/bin/sh -c '/opt/zookeeper/bin/zkServer.sh start /opt/zookeeper/conf/zoo.cfg'
ExecStop=/opt/zookeeper/bin/zkServer.sh stop
Restart=on-failure
RestartSec=2s
[Install]
WantedBy=multi-user.target

:x 保存退出
/opt/zookeeper/bin/zkServer.sh stop

systemctl daemon-reload
systemctl enable zookeeper.service
systemctl start zookeeper.service
systemctl status zookeeper.service

二、部署Kafka

2.1 准备安装包

wget -c https://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.6.0/kafka_2.13-2.6.0.tgz

2.2 安装解压

tar -xf kafka_2.13-2.6.0.tgz -C /opt/
cd /opt/
mv kafka_2.13-2.6.0 kafka

mkdir -p /mnt/cephfs/kafka0/logs /mnt/cephfs/kafka1/logs /mnt/cephfs/kafka2/logs

2.3 添加DNS域名解析或修改hosts文件

[[email protected]:/root]# vim /var/named/lowan.com.zone

kafka0          A       192.168.13.101
kafka1          A       192.168.13.102
kafka2          A       192.168.13.103

systemctl restart named

systemctl start kafka.service 
systemctl status kafka.service 

三、Kubernetes部署kafka-manager

3.1 准备docker镜像文件

方式一：直接pull

docker tag vimagick/cmak:3.0.0.5 harbor.iot.com/kubernetes/kubernetes-kafkamanager:3.0.5
docker push harbor.iot.com/kubernetes/kubernetes-kafkamanager:3.0.5
方式二： 编辑Dockerfile
vim Dockerfile
内容如下：
FROM debian:buster

ENV SCALA_VERSION 2.12.10
ENV SBT_VERSION 1.3.8
ENV CMAK_VERSION 3.0.0.5

RUN set -xe \
    && apt update \
    && apt install -y openjdk-11-jre-headless curl wget \
    && wget -q https://downloads.lightbend.com/scala/$SCALA_VERSION/scala-$SCALA_VERSION.deb -O scala.deb \
    && wget -q https://dl.bintray.com/sbt/debian/sbt-$SBT_VERSION.deb -O sbt.deb \
    && dpkg -i scala.deb sbt.deb \
    && rm scala.deb sbt.deb \
    && rm -rf /var/lib/apt/lists/*

WORKDIR /opt/cmak

RUN set -xe \
    && mkdir src \
    && curl -sSL https://github.com/yahoo/CMAK/archive/$CMAK_VERSION.tar.gz | tar xz --strip 1 -C src \
    && cd src \
    && sbt clean universal:packageZipTarball \
    && cd .. \
    && tar xzf src/target/universal/cmak-$CMAK_VERSION.tgz --strip 1 \
    && rm -rf src

VOLUME /opt/cmak/conf

EXPOSE 9000

ENTRYPOINT ["bin/cmak"]
CMD ["-Dconfig.file=conf/application.conf", "-Dhttp.port=9000", "-Dpidfile.path=/dev/null"]

HEALTHCHECK CMD curl -f http://127.0.0.1/api/health || exit 1


:x 保存退出

docker build -t harbor.iot.com/kubernetes/kubernetes-kafkamanager:3.0.5 .
