手机安装linux性能测试,Linux 性能测试工具 sysbench 的安装与简单使用

2023-05-16

一背景

sysbench是一款开源的多线程性能测试工具，可以执行CPU/内存/线程/IO/数据库等方面的性能测试。

sysbench 支持以下几种测试模式：

1、CPU运算性能

2、内存分配及传输速度

3、磁盘IO性能

4、POSIX线程性能

5、互斥性测试

6、数据库性能(OLTP基准测试)。目前sysbench主要支持 MySQL,PostgreSQL 等几种数据库。

二实验环境

2.1 操作系统

[gysl@gysl-DevOps ~]$ cat /etc/centos-release

CentOS Linux release 7.6.1810 (Core)

2.2 其他配置

安装EPEL，安装方法之前的文章有介绍。

三安装

安装命令如下：

[gysl@gysl-DevOps ~]$ sudo yum -y install sysbench

4.3 测试过程

sysbench 的测试过程一般分为三个阶段：

prepare：准备阶段，准备测试数据。

run：执行测试阶段。

cleanup：清理垃圾数据阶段。

4.4 CPU 性能测试

找出指定范围内最大质数，时间越短 CPU 性能越好。
