ycsb / go-ycsb压测工具的简单试用

官方地址： https://github.com/brianfrankcooper/YCSB

本次这里我们以ycsb压测redis为例。

tar xf ycsb-0.15.0.tar.gz -C /usr/local/
cd /usr/local/ycsb-0.15.0
其中，workloads 目录下是各个压测模板文件

# cat workloads/workload_read   这是我写的一个纯读取的场景的压测模板

recordcount=1000000     # 总共的操作条数
operationcount=1000000  # 总共操作的次数
workload=com.yahoo.ycsb.workloads.CoreWorkload
readallfields=true  # 在读取的时候，是否需要读取所有字段
readproportion=1  # 读取比例
updateproportion=0   # update比例
scanproportion=0
insertproportion=0
requestdistribution=zipfian

开始压测远程的一个codis-proxy

./bin/ycsb load redis -s -P workloads/workload_read -p redis.host=192.168.2.4 -p redis.port=19000 -threads 10    造数据（这步涉及到写操作）

./bin/ycsb run redis -s -P workloads/workload_read -p redis.host=192.168.2.4 -p redis.port=19000  -threads 10    测试纯读取测试
单次测试的结果：

此外，国内的pingcap的唐刘大佬也写了一个go-ycsb的软件，功能上与ycsb类似。

编译方式可以看这个： https://github.com/pingcap/go-ycsb

yum install golang

mkdir /home/gocode/

echo 'export GOPATH=/home/gocode/' >> /root/.bashrc
source /root/.bashrc

git clone https://github.com/pingcap/go-ycsb.git $GOPATH/src/github.com/pingcap/go-ycsb
cd $GOPATH/src/github.com/pingcap/go-ycsb
make
稍等片刻即可完成编译。

编译完成后，用法和 ycsb基本上一样的，压测redis如下写法：

load：

./bin/go-ycsb load redis -P workloads/workload_dba  -p redis.mode=single -p redis.addr=192.168.2.4:19000

run：

./bin/go-ycsb run  redis -P workloads/workload_dba  -p redis.mode=single -p redis.addr=192.168.2.4:19000
