Redis学习2之redis-benchmark使用方法总结

redis-benchmark使用方法总结：包括各个指令的详细解释。

redis-3.0.4

1.redis-benchmark -help 

hadoop@Master:~$ redis-benchmark -help
Invalid option "-help" or option argument missing

Usage: redis-benchmark [-h ] [-p ] [-c ] [-n  [-k ]

 -h       Server hostname (default 127.0.0.1)                    //服务主机名
 -p           Server port (default 6379)                             //服务器端口号
 -s         Server socket (overrides host and port)                //socket，覆盖host和port
 -a       Password for Redis Auth                                //密码
 -c        Number of parallel connections (default 50)            //并行请求的客户端数量，默认50
 -n       Total number of requests (default 100000)              //请求的总量，默认100000
 -d           Data size of SET/GET value in bytes (default 2)        //set或get的数据尺寸，单位是字节，默认是2
 -dbnum         SELECT the specified db number (default 0)             //选择指定的数据号
 -k        1=keep alive 0=reconnect (default 1)                   //布尔量，1代表保持活跃，0代表重连
 -r    Use random keys for SET/GET/INCR, random values for SADD //set/get/incr使用随机的keys,SADD使用随机值...
  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).    //管道请求，默认是1，没管道（并行？）
 -q                 Quiet. Just show query/sec values                       //安静，仅仅展示每秒的查询值
 --csv              Output in CSV format                                    //输出按CSV格式
 -l                 Loop. Run the tests forever
 -t          Only run the comma separated list of tests. The test    //仅仅运行tests
                    names are the same as the ones produced as output.
 -I                 Idle mode. Just open N idle connections and wait.       //闲置模型，进打开N个闲置链接且等待

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__

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

自己看下就能明白意思。

下面简单抛下：

3.测试实例：redis-benchmark -n 1000000 -c 100

这里-n从

-n       Total number of requests (default 100000)

可以看出，代表是请求，总计的请求数量，默认是100000，这里改为了1000000；

-c从

 -c        Number of parallel connections (default 50)

可以看出代表并行链接的客户端数量，默认是50，这里改为了100.
