redis压力测试详解 redis压力测试教程

linux下一般无需下载，windows下redis-benchmark压力测试工具下载地址：http://www.dai*x*iao*rui.com/source/18.html（解压后的redis-benchmark.exe）

压测命令：redis-benchmark -h 127.0.0.1 -p 6379 -c 50 -n 10000

-c表示连接数

-n表示请求数

更多参数请输入 --help 查看~

压测需要一段时间，因为它需要依次压测多个命令的结果，如：get、set、incr、lpush等等，所以我们需要耐心等待，如果只需要压测某个命令，如：get，那么可以在以上的命令后加一个参数-t（红色部分）：

redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -t get

压测结果：

[root@1234 ~]# redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -t get

这样看起来很冗余，如果我们只想看最终的结果，可以带上参数-q，完整的命令如下：

redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -q

显示结果为：

[root@1234 ~]# redis-benchmark -h 127.0.0.1 -p 6086 -c 50 -n 10000 -q

温馨提示：

压测结果跟机器的性能有关，其中windows下压测的结果要比在linux下差一大截。
