./kafka-console-producer.sh –topic mmm_m_m_topic –bootstrap-server 9.124.353.105:9092

提供交互式终端，可以写入消息

./kafka-topics.sh –create –botstrap-server 9.134.153.105:9092 –replication-factor 1 –partition 12 –topic mmm_m_m_topic

创建topic

yum install fio

fio -filename=test.data -direct=1 -iodepth 1 -thread -rw=randrw -ioengine=psync -bs=16k -size=500M -numjobs=10 -runtime=10 -group_reporting -name=mytest

关注write IOPS 和 read IOPS所在行的数据

mkdir -p /etc/etcd.d
mkdir -p /var/etcd/
mkdir -p /var/etcd/wal
vi /etc/etcd.d/etcd.conf
