Usage: redis-benchmark [-h] [-p] [-c] [-n[-k]
 -h     Server hostname (default
 -p     Server port (default 6379)
 -s     Server socket (overrides host and port)
 -c     Number of parallel connections (default 50)
 -n     Total number of requests (default 10000)
 -d      Data size of SET/GET value in bytes (default 2)
 -k      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 get/set keys
  in the form mykey_rand:000000012456 instead of constant
  keys, the argument determines the max
  number of values for the random number. For instance
  if set to 10 only rand:000000000000 - rand:000000000009
  range will be allowed.
 -P       Pipelinerequests. Default 1 (no pipeline).
 -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.


  1. redis-benchmark -h -p 6379 -c 100 -n 100000


  2. redis-benchmark -h -p 6379 -q -d 100


  3. redis-benchmark -t set,lpush -n 100000 -q


  4. redis-benchmark -n 100000 -q script load "‘set’,’foo’,’bar’)"


实测报错如下:writing to socket: connection timed out

输入netstat -an看下端口是不是有很多,重启Redis实例释放连接数,然后重新测试。
