sysbench是一款压力测试工具，可以测试系统的硬件性能，也可以用来对数据库进行基准测试，使用起来很方便，
同时sysbench支持以下几种测试模式：
1、CPU运算性能
2、磁盘IO性能
3、调度程序性能
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能(OLTP基准测试)
目前sysbench主要支持 mysql,drizzle,pgsql,oracle 等几种数据库。
1.
安装sysbench：
yum install epel-release

yum install sysbench -y

使用sysbench --help 查看帮助。

2.sysbench提供了很多自带压测脚本，脚本放在 /usr/share/sysbench 目录下，本文使用安装sysbench压测mysql数据库：

在准备压测的数据库上创建用户和数据库信息：
grant all privileges on *.* to sysbench identified by 'sysbench';
flush privileges;
create database sysbench_db;

a.准备压测数据：

sysbench /usr/share/sysbench/oltp_insert.lua \

 --tables=15 \
 --table-size=500000 \
 --report-interval=10 \
 --threads=128 \
 --time=120 \
 prepare
