kafka3.0集群搭建过程
1.环境说明
服务器资源规划如下表:
IP | hostname | 部署资源 |
---|---|---|
192.168.162.201 | m162p201 | zookeeper,kafka |
192.168.162.202 | m162p202 | zookeeper,kafka |
192.168.162.203 | m162p203 | zookeeper,kafka |
操作系统版本(三个节点均相同):
[root@m162p201 software]# lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch:cxx-4.1-amd64:cxx-4.1-noarch:desktop-4.1-amd64:desktop-4.1-noarch:languages-4.1-amd64:languages-4.1-noarch:printing-4.1-amd64:printing-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.7.1908 (Core) Release: 7.7.1908 Codename: Core
2.环境准备
2.1 依赖软件下载
计划安装的软件:
软件 | 版本 | 安装节点 | 下载地址 |
---|---|---|---|
jdk | jdk-8u311-linux-x64.rpm | m162p201,m162p202,m162p203 | https://www.oracle.com/java/technologies/downloads/#java8 |
zookeeper | apache-zookeeper-3.5.6-bin.tar.gz | m162p201,m162p202,m162p203 | https://archive.apache.org/dist/zookeeper/zookeeper-3.5.6/ |
kafka | kafka_2.12-3.0.0.tgz | m162p201,m162p202,m162p203 | https://kafka.apache.org/downloads#3.0.0 |
eagle | kafka-eagle-bin-1.4.8.tar.gz | m162p201 | http://download.kafka-eagle.org/ |
将上述软件上传到对应服务器的/opt/software目录。
2.2 jdk安装
由于下载的是rpm包。因此直接执行rpm安装命令即可:
[root@m161p114 software]# rpm -ivh jdk-8u311-linux-x64.rpm warning: jdk-8u311-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY Preparing... ################################# [100%] Updating / installing... 1:jdk1.8-2000:1.8.0_311-fcs ################################# [100%] Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... [root@m161p114 software]#
2.3 zookeeper安装
在每台服务器都新建一个zookeeper用户:
useradd -d /opt/zookeeper zookeeper
在 /etc/security/limit.conf中增加如下内容:
zookeeper soft nproc 16384zookeeper hard nproc 16384zookeeper soft nofile 65535zookeeper hard nofile 65536
切换到zookeeper用户 su - zookeeper
建立软链接,便于以后切换版本:
ln -s /opt/zookeeper/zookeeper-3.4.10 /opt/zookeeper/zookeeper
由于采用rpm安装了jdk,因此并不需要重新配置jdk的环境变量。
为了便于后续操作,将zookeeper的环境变量配置上。修改.bash_profile文件。
export ZOOKEEPER_HOME=/opt/zookeeper/apache-zookeeperexport PATH=$ZOOKEEPER_HOME/bin:$PATH
之后重新加载环境变量:
soure .bash_profile
zookeeper配置文件:
# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.# do not use /tmp for storage, /tmp here is just # example sakes.dataDir=/opt/zookeeper/data# the port at which the clients will connectclientPort=2181# the maximum number of client connections.# increase this if you need to handle more clients#maxClientCnxns=60## Be sure to read the maintenance section of the # administrator guide before turning on autopurge.## http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance## The number of snapshots to retain in dataDir#autopurge.snapRetainCount=3# Purge task interval in hours# Set to "0" to disable auto purge feature#autopurge.purgeInterval=1server.1=192.168.162.201:2888:3888 server.2=192.168.162.202:2888:3888 server.3=192.168.162.203:2888:3888
之后建立data目录:
mkdir /opt/zookeeper/dataecho 1 > /opt/zookeeper/data/myid
同样在另外两台服务器将myid配置为 2和3.
上述操作完成之后,可以启动zookeeper:
zkServer.sh start
2.安装kafka
2.1 建立用户并修改环境变量
useradd -d /opt/kafka kafka
在 /etc/security/limit.conf中增加如下内容:
kafka soft nproc 16384kafka hard nproc 16384kafka soft nofile 65535kafka hard nofile 65536
切换到kafka 用户 su - kafka
建立软链接,便于以后切换版本:
tar -zxvf /opt/soft/kafka_2.12-3.0.0.tar.gz ln -s /opt/kafka/kafka_2.12-3.0.0 /opt/kafka/apache-kafka
修改环境变量 .bash_profile文件增加如下内容:
KAFKA_HOME=/opt/kafka/apache-kafkaexport PATH=$KAFKA_HOME/bin:$PATHalias acdconf='cd /opt/kafka/apache-kafka/config/'
2.2 修改kafka配置文件
配置/opt/kafka/apache-kafka/config/server.properties
要修改的参数如下:
m162p201:
broker.id=1listeners=PLAINTEXT://192.168.162.201:9092 log.dirs=/opt/kafka/kafka-logs zookeeper.connect=192.168.162.201:2181,192.168.162.202:2181,192.168.162.203:2181
m162p202:
broker.id=2listeners=PLAINTEXT://192.168.162.202:9092 log.dirs=/opt/kafka/kafka-logs zookeeper.connect=192.168.162.201:2181,192.168.162.202:2181,192.168.162.203:2181
m162p203:
broker.id=3listeners=PLAINTEXT://192.168.162.203:9092 log.dirs=/opt/kafka/kafka-logs zookeeper.connect=192.168.162.201:2181,192.168.162.202:2181,192.168.162.203:2181
2.3 启动kafka
cd /opt/kafka/apache-kafka bin/kafka-server-start.sh -daemon config/server.properties
3.安装管理工具eagle
eagle安装在kafka用户下,不用重新创建目录。此外eagle只需要在一个节点安装即可。
切换到kafka用户:
sudo su - kafkatar -zxvf kafka-eagle-bin-1.4.8.tar.gz
建立软链接,便于后续切换版本:
ln -s /opt/kafka/kafka-eagle-web-1.4.8 /opt/kafka/kafka-eagle
在环境变量中增加eagle的相关内容:
KE_HOME=/opt/kafka/kafka-eagleexport KE_HOME
重新加载环境变量:
source .bash_profile
修改期配置文件:
vim /opt/kafka/kafka-eagle/conf/system-config.properties
修改为如下内容:

由于服务器上没有安装mysql因此,用sqlite即可
kafka.eagle.username=admin
kafka.eagle.password=123456
则指定了eagle登陆的用户名和密码。
监听8048端口。此外,为了eagle采集更多的kafka运行信息,需要开启kafka的jmx服务,修改每个节点kafka的启动脚本
vim /opt/kafka/apache-kafka/bin/kafka-server-start.sh
增加30行内容
28 if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then 29 export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G" 30 export JMX_PORT="7788" 31 fi
之后重启即可。注意每个节点都需要修改。
现在启动eagle
cd /opt/kafka/kafka-eagle/bin

eagle启动完毕。
可以通过如下地址访问:

通过上面配置的用户,admin / 123456登陆。
登陆后界面如下;
另外还提供了一个精美的BScreen:
