安装配置zookeeper

1、安装

[root@linux124 ~]# tar -zxf zookeeper-3.4.14.tar.gz -C /opt
[root@linux124 ~]# cd /opt/zookeeper-3.4.14/conf
[root@linux124 conf]# cp zoo_sample.cfg zoo.cfg
[root@linux124 conf]# vim zoo.cfg

##zoo.cfg

dataDir=/var/lagou/zookeeper/data

[root@linux124 conf]# vim /etc/profile

##/etc/profile

##zookeeper_home
export ZOOKEEPER_PREFIX=/opt/zookeeper-3.4.14
export PATH=$PATH:$ZOOKEEPER_PREFIX/bin
export ZOO_LOG_DIR=/var/lagou/zookeeper/log

# 生效
[root@linux124 conf]# source /etc/profile
# 验证 
[root@linux124 conf]# which zookeeper
/usr/bin/which: no zookeeper in  (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.8.0_261-amd64/bin:/opt/zookeeper-3.4.14/bin:/opt/kafka_2.12-1.0.2/bin:/root/bin)

3、安装配置Kafka

[root@linux124 ~]# tar -zxf kafka_2.12-1.0.2.tgz -C /opt
[root@linux124 ~]# vim /etc/profile

##/etc/profile

##kafka_home
export KAFKA_HOME=/opt/kafka_2.12-1.0.2
export PATH=$PATH:$KAFKA_HOME/bin

#配置/opt/kafka_2.12-1.0.2/config中的server.properties文件：
[root@linux124 ~]# cd /opt/kafka_2.12-1.0.2/config
[root@linux124 config]# vim server.properties

##server.properties

zookeeper.connect=linux124:2181/myKafka
log.dir=/var/lagou/kafka/kafka-logs

[root@linux124 config]# mkdir -p /var/lagou/kafka/kafka-logs

4、启动zookeeper，kafka

#启动zookeeper
[root@linux124 ~]# zkServer.sh start
[root@linux124 ~]# zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-3.4.14/bin/../conf/zoo.cfg

#启动kafka
[root@linux124 ~]# kafka-server-start.sh -daemon /opt/kafka_2.12-1.0.2/config/server.properties 
#验证
[root@linux124 ~]# jps
