hadoop-2.7.3安装kafka_2.11-2.1.0
软件下载:
http://mirrors.shu.edu.cn/apache/kafka/2.1.0/kafka_2.11-2.1.0.tgz
把下载好的包kafka_2.11-2.1.0.tgz 上传到hadoop集群上master:/home/hadoop
解压:
tar -zxvf kafka_2.11-2.1.0.tgz
mv kafka_2.11-2.1.0 kafka_2.11
修改配置文件:
vi server.properties
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=1
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
listeners = PLAINTEXT://master:9092
#listeners=PLAINTEXT://:9092
# A comma separated list of directories under which to store log files
log.dirs=/home/hadoop/kafka_2.11/tmp
# root directory for all kafka znodes.
zookeeper.connect=master:2181,saver1:2181,saver2:2181
一共以上四处地方需要修改!
分别SCP到其他节点
scp -r kafka_2.11 192.168.1.40:/home/hadoop/
scp -r kafka_2.11 192.168.1.50:/home/hadoop/
在192.168.1.40机器上修改的地方有:
vi server.properties
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=2
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
listeners = PLAINTEXT://saver1:9092
#listeners=PLAINTEXT://:9092
在192.168.1.50机器上修改的地方有:
vi server.properties
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=3
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
listeners = PLAINTEXT://saver2:9092
#listeners=PLAINTEXT://:9092
启动kafka
nohup /home/hadoop/kafka_2.11/bin/kafka-server-start.sh /home/hadoop/kafka_2.11/config/server.properties >/dev/null 2>&1 &
停止kafka
/home/hadoop/kafka_2.11/bin/kafka-server-stop.sh
在停止的时候,出现:No kafka server to stop,后天明明有进程,却无法停止。
查看kafka-server-stop.sh脚本,进行脚本修改:
PIDS=$(ps ax | grep -i 'kafka' | grep java | grep -v grep | awk '{print $1}')
三台机器都需要执行。
查看进行:jps
15856 Kafka
验证:
cd /home/hadoop/kafka_2.11/bin
./kafka-topics.sh --create --zookeeper master:2181 --replication-factor 1 --partitions 1 --topic test
完。
