1、安装jdk,kafka的使用要用到jdk
node2:/root#which java
/usr/java/jdk1.8.0_20/bin/java
node2:/root#java -version
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
You have new mail in /var/spool/mail/root
2、安装zookeeper
cd /usr/local/kafka
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz
tar -zxvf zookeeper-3.3.6.tar.gz
export zookeeper_home=/usr/local/kafka/zookeeper-3.3.6
测试zookeeper 是否按照成功:
node2:/usr/local/kafka/zookeeper-3.3.6/bin#./zkServer.sh start
JMX enabled by default
Using config: /usr/local/kafka/zookeeper-3.3.6/bin/../conf/zoo.cfg
grep: /usr/local/kafka/zookeeper-3.3.6/bin/../conf/zoo.cfg: No such file or directory
Starting zookeeper ... STARTED
node2:/usr/local/kafka/zookeeper-3.3.6/bin#
说明启动成功
3、安装kafka
cd /usr/local/kafka
wget https://archive.apache.org/dist/kafka/0.8.0/kafka_2.8.0-0.8.0.tar.gz
tar -zxvf kafka_2.8.0-0.8.0.tar.gz
配置kafka,修改文件server.properties
cd /usr/local/kafka/kafka_2.8.0-0.8.0/config
host.name=192.168.137.3
log.dirs=/usr/local/kafka/log/kafka
zookeeper.connect=localhost:2181
默认为2181端口
配置kafka下zookeeper
mkdir /usr/local/kafka/zookeeper #创建zookeeper目录
mkdir /usr/local/kafka/log/zookeeper #创建zookeeper日志目录
cd /usr/local/kafka/kafka_2.8.0-0.8.0/config
vim zookeeper.properties
dataDir=/usr/local/kafka/zookeeper
dataLogDir=/usr/local/kafka/log/zookeeper
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=100
tickTime=2000
initLimit=10
启动kafka:
cd /usr/local/kafka/kafka_2.8.0-0.8.0/bin
