数据库压测工具Sysbench-0.4.12安装

时间 2019-12-20

原文原文链接

最近公司准备去oracle，迁移到mysql集群。分布式数据库中间件咱们技术选型选择了mycat。这无疑前期的准备工做须要作好，在运维同窗的帮助下，集群已经搭建好，接下来咱们任务就是压测。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类不一样系统参数下的数据库负载状况。它主要包括如下几种方式的测试：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。因为本人是dba，所以重点关注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-8mysql

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

也能够直接点击下载: http://downloads.mysql.com/so...git

安装步骤

sysbench的一些依赖安装

yum -y install  make automake libtool pkgconfig libaio-devel vim-common
若是没有安装mysql,则须要安装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：若是不添加--build=x86_64可能会提示以下错误：github

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作准备的、比较说创建好测试用的表、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 中的测试类型大体能够分红内置的，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:

因为上面的命令都比较简单,相信你们都能看明白,有什么疑问也欢迎你们留言交流.sql

能够对数据库进行调优后，再使用sysbench对OLTP进行测试，看看TPS是否是会有所提升。docker

注意：sysbench的测试只是基准测试，并不能表明实际企业环境下的性能指标。shell
