一、kafka-manager简介
项目地址为:https://github.com/yahoo/kafka-manager
为了简化开发者和服务工程师维护Kafka集群的工作,yahoo构建了一个叫做Kafka管理器的基于Web工具,叫做 Kafka Manager。这个管理工具可以很容易地发现分布在集群中的哪些topic分布不均匀,或者是分区在整个集群分布不均匀的的情况。它支持管理多个集群、选择副本、副本重新分配以及创建Topic。同时,这个管理工具也是一个非常好的可以快速浏览这个集群的工具,有如下功能:
- 管理kafka集群
- 方便集群状态监控 (包括topics, consumers, offsets, brokers, replica distribution, partition distribution)
- 方便选择分区副本
- 配置分区任务,包括选择使用哪些brokers
- 可以对分区任务重分配
- 提供不同的选项来创建及删除topic
- Topic list会指明哪些topic被删除
- 批量产生分区任务并且和多个topic和brokers关联
- 批量运行多个主题对应的多个分区
- 向已经存在的主题中添加分区
- 对已经存在的topic修改配置
- 可以在broker level和topic level的度量中启用JMX polling功能
- 可以过滤在ZK上没有ids/ owners/offsets/ directories的consumer
二、下载kafka-manager源码包
源码包下载地址:https://github.com/yahoo/kafka-manager/archive/2.0.0.2.tar.gz
github上没有提供安装包,需要我们自行编译之后在进行安装,需要现在sbt编译工具。
再此我已经编译好安装包了kafka-manager-2.0.0.2.zip,可以直接下载使用:https://pan.baidu.com/s/10hiEuECfZ6UuI4yIY1dluw
关注微信公众号回复【kafka manager】或者【卡夫卡】获取提取码
看到我这篇文章,就不要去编译,没意思还浪费时间,直接从百度网盘链接下载编译好的安装包就行了,编译步骤参考一下就行了。
三、安装sbt-1.3.5
[root@localhost ~]# curl https://bintray.com/sbt/rpm/rpm > bintray-sbt-rpm.repo
[root@localhost ~]# mv bintray-sbt-rpm.repo /etc/yum.repos.d/
[root@localhost ~]# yum install sbt -y
因为Kafka-manager使用的Play框架,为了编译的速度更快,先配置sbt的maven仓库,由于默认仓库速度较慢,因此使用aliyun提供的maven仓库。
修改仓库地址:(sbt 默认下载库文件很慢, 还时不时被打断,不行的话就重试),我们可以在用户目录下创建 touch ~/.sbt/repositories, 填上阿里云的镜像 # vi ~/.sbt/repositories
cd ~
mkdir .sbt
touch ~/.sbt/repositories
vi ~/.sbt/repositories
内容:
[repositories]
local
#oschina: http://maven.oschina.net/content/groups/public/
aliyun-nexus: http://maven.aliyun.com/nexus/content/groups/public/
jcenter: http://jcenter.bintray.com/
typesafe-ivy-releases: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
maven-central: http://repo1.maven.org/maven2/
以上配置文件解释顺序是:本地→阿里云镜像→jcenter→typesafe-ivy-releases→Maven主镜像。如果需要添加公司的maven镜像,可以按照 key: value 的形式添加,key 的命名没有要求(暂时没注意到,但是最好也不要用什么特殊符号吧)
验证:检查sbt是否安装成功,查看命令输出,发现已经成功可以从maven.aliyun.com/nexus
下载到依赖即表示成功
sbt -version
需要很长时间~耐心等待,我这里已经执行过了,再次执行显示如下:
[root@localhost ~]# sbt -version
[info] [launcher] getting org.scala-sbt sbt 1.3.5 (this may take some time)...

四、解压编译kafka-manager源码包
在【二、下载kafka-manager源码包】步骤中我们已经已下载了源码包,
解压kafka-manager源码包:
[root@localhost soft]# tar -zxvf kafka-manager-2.0.0.2.tar.gz
解压后显示目录如下
[root@localhost soft]# ll
总用量 56
drwxrwxr-x. 9 root root 109 4月 12 2019 app
-rw-rw-r--. 1 root root 4242 4月 12 2019 build.sbt

drwxrwxr-x. 4 root root 37 4月 12 2019 src
drwxrwxr-x. 5 root root 51 4月 12 2019 test
然后执行:
./sbt clean dist
编译时间会很长,需要耐心等待,可以到~/.sbt/boot/update.log 查看sbt更新日志。sbt更新好,就开始下载各种jar包,最后看到:[info] Your package is ready in /home/soft/kafka-manager-2.0.0.2/target/universal/kafka-manager-2.0.0.2.zip 证明编译好了。
我这个已经编译过了,由于记录笔记,我再次进行了编译就很快了,日志如下:
[root@localhost kafka-manager-2.0.0.2]# ./sbt clean dist

五、安装kafka-manager
由于使用kafka-manager是在JDK8基础上的,所以先安装JDK8,JDK安装不再叙述。
由于【四、解压编译kafka-manager源码包】步骤已经编译完成,我们可以把 /home/soft/kafka-manager-2.0.0.2/target/universal/kafka-manager-2.0.0.2.zip 的安装包移动到你要安装的地方解压。
在此我解压到/usr/local/目录下
unzip kafka-manager-2.0.0.2.zip -d /usr/local/
解压后查看目录如下:
[root@localhost kafka-manager-2.0.0.2]# ll
总用量 28
drwxr-xr-x. 2 root root 4096 12月 25 14:57 bin
drwxr-xr-x. 2 root root 108 12月 25 14:57 conf
drwxr-xr-x. 2 root root 8192 12月 25 14:57 lib
-rw-r--r--. 1 root root 8686 4月 12 2019 README.md
drwxr-xr-x. 3 root root 17 12月 25 14:57 share
接下来就是配置kafka-manager了
vi conf/application.conf
#修改kafka-manager.zkhosts列表为自己的zk节点
kafka-manager.zkhosts="192.168.184.133:2181"
#添加http访问端口配置,默认9000
http.port=9090
想要看到读取,写入速度需要开启JMX,修改kafka-server-start.sh 添加一行即可:添加JMX端口8999
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
export JMX_PORT="8999"
fi
注意:每个kafka broker都需要修改,修改后进行重启kafka。
最后,启动kafka-manager
cd kafka-manager/bin
nohup ./kafka-manager -Dconfig.file=../conf/application.conf >/dev/null 2>&1 &
六、测试kafka-manager
访问:http://192.168.184.133:9090/
1、新建Cluster
点击【Cluster】>【Add Cluster】打开如下添加集群配置界面:输入集群的名字(如KafkaCluster
)和 Zookeeper 服务地址(如192.168.184.133:2181/kafka
),选择最接近的Kafka版本
其他broker的配置可以根据自己需要进行配置,默认情况下,点击【保存】时,会提示几个默认值为1
的配置错误,需要配置为>=2
的值。提示如下。
添加完集群之后查看
topics相关:
更多页面功能自己点点就行了。。。

命令: nload
真是个良心站点哇,大公无私,爱了爱了
还可以直接搞一张映射表,存 uid | time | source_index, 第一次直接查对应的 time 选出前100, 第二次直接用 CompleteFuture 去分别用 source_in
干得漂亮,多个朋友堵条路
2021.2.2版本的不适用吧
现在还可以用么
激活码有用,感谢分享
