redis压力测试

redis自带的redis-benchmark工具

Redis 自带了一个叫redis-benchmark的工具来模拟 N 个客户端同时发出 M 个请求。 (类似于 Apache ab 程序)。你可以使用 redis-benchmark -h 来查看基准参数。
+ 1 使用方法 redis-benchmark [-h ] [-p ] [-c ] [-n

[root@redis-test-slave ~ ]$ redis-benchmark --help
Usage: redis-benchmark [-h ] [-p ] [-c ] [-n  [-k <boolean>]

 -h       Server hostname (default 127.0.0.1)
 -p           Server port (default 6379)
 -s         Server socket (overrides host and port)
 -a       Password for Redis Auth
 -c        Number of parallel connections (default 50)
 -n       Total number of requests (default 100000)
 -d           Data size of SET/GET value in bytes (default 2)
 --dbnum         SELECT the specified db number (default 0)
 -k <boolean>       1=keep alive 0=reconnect (default 1)
 -r    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         Pipeline  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          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:
   # 运行默认配置下的测试
   $ redis-benchmark

 Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1:
   # 指定并发数20,总请求数为10W,redis server主机IP为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:
   # 测试SET随机数性能
   $ redis-benchmark -t set -n 1000000 -r 100000000

 Benchmark 127.0.0.1:6379 for a few commands producing CSV output:
   # 测试结果输出到csv
   $ redis-benchmark -t ping,set,get -n 100000 --csv

 Benchmark a specific command line:
   # 执行特定命令下的测试
   $ redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0

 Fill a list with 10000 random elements:
   # 测试list入队的速度
   $ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__

 On user specified command lines __rand_int__ is replaced with a random integer
 with a range of values selected by the -r option.
