redis-benchmark使用教程

redis-benchmark

redis-benchmark是一个测试redis性能的工具，Redis 性能测试是通过同时执行多个命令实现的

语法

redis-benchmark [option] [option value]
注意：该命令是在 redis 的目录下执行的，而不是 redis 客户端的内部指令。

参数

序号 选项 描述 默认值
1 -h 指定服务器主机名 127.0.0.1
2 -p 指定服务器端口 6379
3 -s 指定服务器 socket
4 -c 指定并发连接数 50
5 -n 指定请求数 10000
6 -d 以字节的形式指定 SET/GET 值的数据大小 2
7 -k 1=keep alive 0=reconnect 1
8 -r SET/GET/INCR 使用随机 key, SADD 使用随机值
9 -P 通过管道传输 请求 1
10 -q 强制退出 redis。仅显示 query/sec 值
11 --csv 以 CSV 格式输出
12 -l 生成循环，永久执行测试
13 -t 仅运行以逗号分隔的测试命令列表。
14 -I Idle 模式。仅打开 N 个 idle 连接并等待。

实例

# 随机set,get 1000000条命令
redis-benchmark -h $host -p $port -t set,get -r 1000000 -n 1000000 -c 100 -a $password
