redis cluster 压力测试

测试工具：redis-benchmark

测试版本：redis cluster 5.0.7

测试架构：

基中m1,m2,m3 为三个独立机房

测试结果：

测试脚本：


#!/bin/bash

#CLIENTS=50              #defaul clients
HOST='192.168.1.1'
PORT=4000
PWD='benchtest'  # if have passwod
end_clients=2000
CMDS="set"
cmd_arry=(set get incr sadd mset mget hset)  #ad hoc test redis command
KEYSPACE=100000
TOTAL_REQUESTS=500000    #default 100000
data_size=100            #Data size of SET/GET value in bytes (default 3)
CURRENT_DATE=`date +%Y%m%d`
bench_file='redis-benchmark'-${CURRENT_DATE}
benchmark='/redis/base/bin/redis-benchmark'

benchmark(){
    cmd=$1
    for clients in `seq 50 50 $end_clients`;do
        if [ x"$pipeline" != "x" ];then
           with_pipeline="-P $pipeline"
        fi
        benchmark_cmd="$benchmark -h $HOST -p $PORT -c $clients  $with_pipeline -r $KEYSPACE -n $TOTAL_REQUESTS -t $cmd -d $data_size"
        echo "[info] `date +"%Y-%m-%d %H:%M:%S"` : $benchmark_cmd ">>benchmark_cmd.log
        tps=`$benchmark_cmd | grep "requests per second" | awk '{print $1}'`
        echo "$cmd,$clients,$data_size,$tps" | tee -a ${bench_file}_${cmd}.txt
    done
}

for cmdelement in ${cmd_arry[@]};do
    echo $cmdelement
    benchmark $cmdelement #don't use pipline 
done

测试结论：在value 为100byte 请求为500000 ，KEYSPACE 为100000的情况下，redis 的tps 为7w左右

redis-benchmark 帮助文档：

Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests>] [-k <boolean>]

 -h <hostname>      Server hostname (default 127.0.0.1)
 -p <port>          Server port (default 6379)
 -s <socket>        Server socket (overrides host and port)
 -a <password>      Password for Redis Auth
 -c <clients>       Number of parallel connections (default 50)
 -n <requests>      Total number of requests (default 100000)
 -d <size>          Data size of SET/GET value in bytes (default 3)
 --dbnum <db>       SELECT the specified db number (default 0)
 -k <boolean>       1=keep alive 0=reconnect (default 1)
 -r <keyspacelen>   Use random keys for SET/GET/INCR, random values for SADD
  Using this option the benchmark will expand the string __rand_int__
  inside an argument with a 12 digits number in the specified range
  from 0 to keyspacelen-1. The substitution changes every time a command
  is executed. Default tests use this to hit random keys in the
  specified range.
 -P <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).
 -e                 If server replies with errors, show them on stdout.
                    (no more than 1 error per second is displayed)
 -q                 Quiet. Just show query/sec values
 --csv              Output in CSV format
 -l                 Loop. Run the tests forever
 -t <tests>         Only run the comma separated list of tests. The test
                    names are the same as the ones produced as output.
 -I                 Idle mode. Just open N idle connections and wait.

Examples:

 Run the benchmark with the default configuration against 127.0.0.1:6379:
   $ redis-benchmark

 Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1:
   $ redis-benchmark -h 192.168.1.1 -p 6379 -n 100000 -c 20

 Fill 127.0.0.1:6379 with about 1 million keys only using the SET test:
   $ redis-benchmark -t set -n 1000000 -r 100000000

 Benchmark 127.0.0.1:6379 for a few commands producing CSV output:
   $ redis-benchmark -t ping,set,get -n 100000 --csv

 Benchmark a specific command line:
   $ redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0

 Fill a list with 10000 random elements:
   $ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__
