数据库压测工具Sysbench-0.4.12安装

作者: 程序员七哥 | 来源:发表于2019-10-16 02:06 被阅读0次

最近公司准备去oracle，迁移到mysql集群。分布式数据库中间件我们技术选型选择了mycat。这无疑前期的准备工作需要做好，在运维同学的帮助下，集群已经搭建好，接下来我们任务就是压测。这篇文章简单记录我所选择的压测工具Sysbench的安装和使用。

sysbench 简介

Sysbench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。它主要包括以下几种方式的测试：cpu性能，磁盘io性能，线程调度性能，内存分配及传输速度和数据库性能。由于本人是dba，因此重点关注sysbench测试数据库的场景。目前sysbench支持mysql，postgreSQL，oracle三种数据源。

测试环境

系统：Centos-8

Sysbench：sysbench-0.4.12.10,下载地址：https://github.com/akopytov/sysbench

也可以直接点击下载: http://downloads.mysql.com/source/sysbench-0.4.12.10.tar.gz

安装步骤

sysbench的一些依赖安装

yum -y install  make automake libtool pkgconfig libaio-devel vim-common
如果没有安装mysql,则需要安装mysql-devel
yum install mysql-devel

安装sysbench

cd /data/sysbench/sysbench-0.4.12

执行autogen.sh用它来生成configure这个文件

./autogen.sh

执行configure && make && make install 来完成sysbench的安装

./configure --prefix=/wls/sysbench/ --build=x86_64 
make && make install

注：如果不添加--build=x86_64可能会提示如下错误：

checking build system type... Invalid configuration `x86_64-unknown-linux-': machine `x86_64-unknown-linux' not recognized

configure: error: /bin/sh config/config.sub x86_64-unknown-linux- failed

sysbench 对数据库进行压力测试的过程

prepare 阶段这个阶段是用来做准备的、比较说建立好测试用的表、并向表中填充数据;
run阶段这个阶段是才是去跑压力测试的SQL;
cleanup 阶段这个阶段是去清除数据的、也就是prepare阶段初始化好的表要都drop掉;

sysbench 中的测试类型大致可以分成内置的，lua脚本自定义的测试

内置: fileio 、cpu 、memory 、threads 、 mutex
lua脚本自定义型：sysbench 自身内涵了一些测试脚本放在了安装目录下:

由于上面的命令都比较简单,相信大家都能看明白,有什么疑问也欢迎大家留言交流.

可以对数据库进行调优后，再使用sysbench对OLTP进行测试，看看TPS是不是会有所提高。

注意：sysbench的测试只是基准测试，并不能代表实际企业环境下的性能指标。
