Centos7编译安装kafka-manager-2.0.0.2

几个T的资料等你来白嫖
双倍快乐
一定要收藏这个宝藏网站防止丢失,求助资源~!!!

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:

  1. 管理kafka集群
  2. 方便集群状态监控 (包括topics, consumers, offsets, brokers, replica distribution, partition distribution)
  3. 方便选择分区副本
  4. 配置分区任务,包括选择使用哪些brokers
  5. 可以对分区任务重分配
  6. 提供不同的选项来创建及删除topic
  7. Topic list会指明哪些topic被删除
  8. 批量产生分区任务并且和多个topic和brokers关联
  9. 批量运行多个主题对应的多个分区
  10. 向已经存在的主题中添加分区
  11. 对已经存在的topic修改配置
  12. 可以在broker level和topic level的度量中启用JMX polling功能
  13. 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

20201123201824105.jpg

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)...
:: loading settings :: url = jar:file:/usr/share/sbt/bin/sbt-launch.jar!/org/apache/ivy/core/settings/ivysettings.xml

    confs: [default]
    6 artifacts copied, 0 already retrieved

sbt script version: 1.3.5

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. 2 root root   108 4月  12 2019 conf

-rwxrwxr-x. 1 root root 21353 4月  12 2019 sbt

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/

20201123201824262.png

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

20201123201824335.png

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

更多页面功能自己点点就行了。。。
