1.环境信息
| OS Version | Zookeeper Version | User |
| RHEL7.7 | 3.8.0 | root |
kafka官网下载地址：Apache Kafka
备注：与<4.zookeeper单实例安装>在同一台服务器。也需要jdk支持
2.kafka单实例安装
1.上传kafka_2.13-3.3.2.tgz
E.g：上传至/opt目录
2.解压
命令：
tar -zxvf kafka_2.13-3.3.2.tgz
3.配置server.properties
命令：
cd /opt/kafka_2.13-3.3.2/config
vim server.properties
#kafka日志目录
log.dirs=/tmp/kafka-logs
更改至(按需更改)：
log.dirs=/opt/kafka
#zookeeper配置节点
#由于kafka与zookeeper在同一台服务器，保持localhost值不会
zookeeper.connect=localhost:2181
#其它参数保持默认
完整的server.properties
命令：
grep -aiwvE "^#|^$" server.properties
broker.id=0
listeners=PLAINTEXT://:9092
#advertised.listeners=PLAINTEXT://your.host.name:9092
#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

4.启动kakfa
前提：zookeeper要启动起来
命令：
./kafka-server-start.sh -daemon /opt/kafka_2.13-3.3.2/config/server.properties
[root@rhel77 bin]# pwd
/opt/kafka_2.13-3.3.2/bin
[root@rhel77 bin]#
[root@rhel77 bin]# ./kafka-server-start.sh -daemon /opt/kafka_2.13-3.3.2/config/server.properties
[root@rhel77 bin]#
5.查看kafka进程和端口
命令：
ps -ef |grep -ai kafka
netstat -antulp | grep -aiwE 9092
[root@rhel77 bin]# ps -ef |grep -ai kafka
