ycsb是yahoo开源的一个多功能压测软件,支持mysql mongodb redis hbase等多种软件。
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

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
