mv /opt/apache-zookeeper-3.8.0-bin/ /opt/zookeeper


cd /opt/zookeeper/conf/
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg

# 修改如下内容
dataDir=/opt/zookeeper/zkData
dataLogDir=/opt/zookeeper/zkLog

cd /opt/zookeeper/bin/
# 启动zookeeper
./zkServer.sh start
# 查看进程是否启动
jps
# 查看状态
./zkServer.sh status
# 停止zookeeper
./zkServer.sh stop

安装kafka

tar -xzf kafka_2.13-3.1.0.tgz

如果使用集群，还要修改下面配置

启动命令:

# 先启动zookeeper
cd /opt/zookeeper/bin/
./zkServer.sh start
# 再启动kafka
cd /home/kafka_2.13-3.1.0/
bin/kafka-server-start.sh config/server.properties

此方式可以实时查看日志.

后台启动方式:

./kafka-server-start.sh -daemon ../config/server.properties

查询进程和关闭命令

jps
./kafka-server-stop.sh
