Redis-benchmark是Redis官方自带的Redis性能测试工具,可以有效的测试Redis服务的性能,本文主要介绍相关信息。
Redis-benchmark参数的使用说明如下所示。
Usage: redis-benchmark [-h] [-p] [-c] [-n[-k] -h Server hostname (default 127.0.0.1) -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.
Redis-benchmark命令的使用示例如下所示。
redis-benchmark -h 192.X.X.201 -p 6379 -c 100 -n 100000
redis-benchmark -h X.X.X.X -p 6379 -q -d 100
redis-benchmark -t set,lpush -n 100000 -q
redis-benchmark -n 100000 -q script load "redis.call('set','foo','bar')"
redis-benchmark -h X.X.X.X -p 18000 -c 5000 -n 100000 -q系统显示类似如下。
netstat -an
命令,查看Redis相关端口是否有很多。如果很多,重启Redis实例释放连接数,然后重新测试即可。
