创建topic脚本

#!/bin/bash
# create topic
topic='vehiclepass'
cd /opt/ops/kafka/kafka_2.12-2.0.0/bin
zk_ip=$(cat /opt/ops/kafka/kafka_2.12-2.0.0/config/server.properties | grep zookeeper.connect= | awk -F'=' '{ print $2 }' | sed s/[[:space:]]//g)
partitions_num=$(cat /opt/ops/kafka/kafka_2.12-2.0.0/config/server.properties | grep num.partitions= | awk -F'=' '{ print $2 }' | sed s/[[:space:]]//g)
./kafka-topics.sh --create --zookeeper $zk_ip --topic $topic --partitions $partitions_num --replication-factor 1
