CentOS安装KafkaManager

一、下载

下载地址：https://github.com/yahoo/CMAK/releases

shell> wget https://codeload.github.com/yahoo/CMAK/tar.gz/2.0.0.2

说明：之前叫Kafka Manager，现在改名叫CMAK（Cluster Manager for Apache Kafka）了，网页下载之后的压缩包名字是CMAK-2.0.0.2.tar.gz，wget下载后的压缩包名字是2.0.0.2.tar.gz（如果是2.0.0.0或更老版本，wget下载后的压缩包名字只有版本号，没有后缀名，但是也可以直接解压）

二、解压

shell> tar -zxvf CMAK-2.0.0.2.tar.gz -C /usr/local/

解压后的目录为CMAK-2.0.0.2

三、sbt编译

kafka-manager需要sbt编译，所以如果没有安装sbt需要先安装下

1、yum

shell> curl https://bintray.com/sbt/rpm/rpm | sudo tee /etc/yum.repos.d/bintray-sbt-rpm.repo
shell> sudo yum install sbt

2、手动安装

下载地址：https://www.scala-sbt.org/download.html

shell> wget https://piccolo.link/sbt-1.3.8.tgz
shell> tar -zxvf sbt-1.3.8.tgz -C /usr/local/

添加环境变量

shell> vim /etc/profile

export PATH=/usr/local/sbt/bin:$PATH

shell> source /etc/profile

3、修改仓库地址（sbt默认下载库很慢，这里添加阿里云仓库，类似使用maven时添加阿里云仓库提高速度）

shell> vim ~/.sbt/repositories

添加以下内容

[repositories]
local
aliyun: http://maven.aliyun.com/nexus/content/groups/public/
typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
sonatype-oss-releases
maven-central
sonatype-oss-snapshots

4、编译

这个过程会很漫长，因为要下载很多依赖包，甚至开始看起来像是卡住了一样，耐心等待，再等待...

（如果真的要折腾，建议开个后台进程，不想等的下面有编译好的链接）

编译成功后会在target/universal/目录下生成一个可用于部署的kafka-manager-2.0.0.2.zip

我这里时间看起来没有那么那么长，主要是因为之前编译过一次了，为了测试和截图又重新来了一遍...

如果有时间愿意折腾可以按照以上步骤尝试一下，如果不想经历着漫长的等待，推荐大家直接下载编译好的zip，这里我把自己编译过的几个版本分享下：

1.3.3.22：链接:https://pan.baidu.com/s/1PyRI... 密码:7v8r

2.0.0.0：链接:https://pan.baidu.com/s/1lYvy... 密码:7wd9

2.0.0.2：链接:https://pan.baidu.com/s/1fiQv... 密码:hh4w

另外，3.0.0.2之后貌似已经提供了编译好的版本，不过我没有试，看大小和目录结构应该是，只是新版本要求JDK 11+，配置和启动部分名称都有所调整，需要稍微注意下（kafka-manager改成了cmak）有兴趣的可以尝试下

四、配置

shell> vim /usr/local/CMAK-2.0.0.2/conf/application.conf

编辑kafka-manager.zkhosts

kafka-manager.zkhosts="my.zookeeper.host.com:2181"

如果是集群：

kafka-manager.zkhosts="my.zookeeper.host.com:2181,other.zookeeper.host.com:2181"

五、运行

kafka-manager默认使用9000端口，使用-Dhttp.port指定端口

shell> cp kafka-manager-2.0.0.2.zip /usr/local/
shell> unzip kafka-manager-2.0.0.2.zip
shell> cd /usr/local/kafka-manager-2.0.0.2
shell> bin/kafka-manager -Dconfig.file=conf/application.conf -Dhttp.port=9002

后台启动

shell> nohup bin/kafka-manager -Dconfig.file=conf/application.conf -Dhttp.port=9002 >/dev/null 2>&1 &

六、使用

添加Cluster

Cluster ZooKeeper Hosts：zk1:2181,zk2:2181,zk3:2181/NAMESPACE

勾选红框部分，前提是 kafka 启动时开启了 JMX_PORT才会生效

shell> cd /usr/local/kafka_2.12-2.2.0
shell> JMX_PORT=9999 bin/kafka-server-start.sh -daemon config/server.properties

查看topic及Consumer

到目前为止，kafka-manager的安装和基本配置就完成了，更多详细用法可以参考开源项目：https://github.com/yahoo/CMAK
