• 3.给脚本赋权

chmod 777 /usr/local/bin/kafkacmd.sh

• 4.如果要使用stop

vim /export/servers/kafka/bin/kafka-server-stop.sh

# PIDS=$(ps ax | grep -i 'kafka\.Kafka' | grep java | grep -v grep | awk '{print $1}')
PIDS=$(ps ax | grep -i 'Kafka' | grep java | grep -v grep | awk '{print $1}')

• 5.再分发kafka-server-stop.sh

scp /export/servers/kafka/bin/kafka-server-stop.sh node02:/export/servers/kafka/bin/

scp /export/servers/kafka/bin/kafka-server-stop.sh node03:/export/servers/kafka/bin/

• 6.使用

kafkacmd.sh status 查看状态

kafkacmd.sh start 开启

kafkacmd.sh stop 停止
