1 概述
memtier_benchmark是一种高吞吐量的性能基准测试工具，主要用于Redis和Memcached。它是 Redis官方开发团队开发的，旨在生成各种流量模式，以便测试和优化以上两个数据库的性能。
memtier_benchmark的一些关键特点如下：
多协议支持
memtier_benchmark 支持 Redis 和 Memcached（包括二进制和文本协议），可以用于比较不同场景下的性能表现。
多线程与多客户端
该工具能够启动多个工作线程，每个线程可以驱动配置数量的客户端，从而更好地利用硬件资源，生成高负载流量。
可定制的测试选项
用户可以通过选项来控制 GET 和 SET 操作的比例、键的使用模式（随机或顺序）、键的过期时间范围等，以模拟不同的访问模式。
报告生成
memtier_benchmark 能够在多次测试迭代后自动生成最佳、最差和平均结果的报告，帮助用户深入了解系统性能。
2 环境
benchmark服务器（华为云），8C8G，centos 7.9，编译安装memtier_benchmark。
redis服务器（X实例并开启redis加速），8C16G，centos 7.9，IP是10.0.24.81。
两台服务器都处于同一个az和同一个子网中。
3 部署memtier_benchmark
安装编译memtier_benchmark需要的依赖文件，以及下载源码。
yum install git -y
yum install autoconf automake make gcc-c++ pcre-devel zlib-devel libmemcached-devel libevent-devel openssl-devel -y
cd /opt
git clone https://github.com/RedisLabs/memtier_benchmark.git
cd memtier_benchmark
编译程序，命令如下：
autoreconf -ivf
./configure
make && make install
which memtier_benchmark
memtier_benchmark -v
命令行的常用参数：
- -s, --server=ADDR: 服务器地址。
- -p, --port=PORT: 服务器端口（默认值：6379）。
- -n, --requests=NUMBER: 每个客户端的总请求数（默认值：10000）。使用 allkeys 在整个键范围内运行。
- --rate-limiting=NUMBER: 每个连接每秒最大请求数（默认无限制）。
- -c, --clients=NUMBER: 每个线程的客户端数（默认值：50）。
- -t, --threads=NUMBER: 线程数（默认值：4）。
- --test-time=SECS: 测试运行的秒数。
- --ratio=RATIO: Set:Get 比例（默认值：1:10）。
- --pipeline=NUMBER: 并发流水线请求数（默认值：1）。
- --reconnect-interval=NUM: 执行多少请求后重新连接。
- --multi-key-get=NUM: 启用多键获取命令，最多获取 NUM 键（默认值：0）。
- --select-db=DB: 选择数据库编号（测试 Redis 服务器时）。
- --distinct-client-seed: 为每个客户端使用不同的随机种子。
- --randomize: 基于时间戳的随机种子（默认值为固定值）。
4 部署redis
在华为云上购买X实例服务器，选择欧拉系统（使用此系统才有redis加速效果），并开启redis加速。
开启redis加速的X实例服务器是自动安装了redis rpm包，需要修改redis.conf文件以使得redis监听在所有网卡上，执行如下命令：
echo "bind 0.0.0.0" >> /etc/redis/redis.conf
systemctl restart redis
5 压测
目标redis的IP是10.0.24.81，-t表示压测工具开启的线程数，-c表示一个线程启动的客户端数量，-d表示请求消息的大小（单位为字节），-n表示一个客户端发送的请求数量。
memtier_benchmark -s 10.0.24.81 -p 6379 -t 32 -c 32 -d 1024 -n 100000
压测输出报告如下，重点关注Ops/sec和p99 Latency。
