jdk+zookeeper+kafka 搭建kafka集群

环境准备

环境资源包：
jdk-8u341-linux-x64.tar.gz
kafka_2.12-2.2.0.tgz
zookeeper-3.4.14.tar.gz

server-id	ip	状态
server1	10.206.120.10	leader
server2	10.206.120.2	follower
server3	10.206.120.3	follower

一、安装jdk

因为kafka需要Java环境，所以优先配置jdk环境，若已经配置了java环境，此步骤可以忽略

[root@VM-120-2-centos ~]# tar -xvf jdk-8u341-linux-x64.tar.gz 
[root@VM-120-2-centos ~]# mv jdk1.8.0_341/ /usr/local/
#在文件末尾加入以下语句
[root@VM-120-2-centos ~]# vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_341
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib

[root@VM-120-2-centos ~]# source /etc/profile
[root@VM-120-2-centos ~]# java -version
java version "1.8.0_341"
Java(TM) SE Runtime Environment (build 1.8.0_341-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.341-b10, mixed mode)
至此jdk环境配置完成

二、zookeeper集群安装

[root@VM-120-2-centos ~]#  cd 
[root@VM-120-2-centos ~]# tar -xvf zookeeper-3.4.14.tar.gz 
[root@VM-120-2-centos ~]# mv zookeeper-3.4.14 /usr/local/zookeeper
[root@VM-120-2-centos ~]# cd /usr/local/zookeeper/conf/
[root@VM-120-2-centos ~]# cp zoo_sample.cfg zoo.cfg
[root@VM-120-2-centos ~]# vim zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataLogDir=/usr/local/zookeeper/logs
dataDir=/usr/local/zookeeper/data
clientPort=2181
autopurge.snapRetainCount=500
autopurge.purgeInterval=24
server.1= 10.20
