这篇文章主要介绍了MySQL中压测工具Sysbench1.0怎么用,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
一、简介
Sysbench压测工具常用版本有0.4(较旧),0.5(据说非官方正宗开源版),1.0(最新的官方开源版本),不同版本之间的系统压测差异较小。但对数据库的压测参数、结果具有较大差异,这里针对sysbench压测MYSQL数据库做下安装、使用介绍。
二、压测环境
硬件环境:
测试机 | Dell PowerEdge R730xd |
CPU | Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz (2物理CPU,每个6核心,每个核心2线程,总共24processor) |
内存 | 128G |
RAID卡 | PERC H730P Mini Memory Size : 2048MB |
raid级别 | Raid-5 |
文件系统 | xfs |
硬盘 | 4T SAS * 12 |
软件环境:
操作系统 | Red Hat Enterprise Linux Server release 6.5 (Santiago) |
内核 | 2.6.32-431.el6.x86_64 |
MYSQL版本 | 5.7.17 |
压测工具 | sysbench 1.0.3 |
三、MYSQL核心参数
四、压测模型
测试工具 | sysbench |
测试记录数 | 1,000,000 |
测试模式 | complex |
run time(秒) | 300 |
最大请求数 | 100,000 |
并发线程数 | 1000 |
五、MYSQL压测过程
以oltp_read_write.lua压测为案例
1、sysbench2.0压测工具安装——请参照压测工具之Sysbench(1_系统压测)
2、sysbench oltp压测数据准备
sysbench /usr/local/sysbench/share/sysbench/oltp_read_write.lua --mysql-host=10.1.0.10 --mysql-port=3306 --mysql-user=dbuser --mysql-password=abc.1234 --mysql-db=dbtest --tables=10 --table-size=1000000 --report-interval=10 --threads=1000 --time=300 prepare

2、sysbench oltp压测开始
sysbench /usr/local/sysbench/share/sysbench/oltp_read_write.lua --mysql-host=10.1.0.10 --mysql-port=3306 --mysql-user=dbuser --mysql-password=abc.1234 --mysql-db=dbtest --tables=10 --table-size=1000000 --report-interval=10 --threads=1000 --time=300 run

[root@DB_TEST sysbench]# sysbench /usr/local/sysbench/share/sysbench/oltp_read_write.lua --mysql-host=10.1.0.10 --mysql-port=3306 --mysql-user=dbuser --mysql-password=abc.1234 --mysql-db=dbtest --tables=10 --table-size=1000000 --report-interval=10 --threads=1000 --time=300 run
sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)

##下面每隔10S产生的压测报告数据也与之前版本有较大差别

SQL statistics:

Threads fairness:

execution time (avg/stddev): 300.1863/0.07
备注:需要重点关注的数据有执行总时间、TPS:如果使用-skip-trx=on,这项事务数恒为0,需要用total number of events 去除以总时间,得到tps(其实还可以分为读tps和写tps),QPS和RT(平均响应时间),以及系统压测指标CPU、内存、IO等。
3、sysbench oltp压测数据清理
sysbench /usr/local/sysbench/share/sysbench/oltp_read_write.lua --mysql-host=10.1.0.10 --mysql-port=3306 --mysql-user=dbuser --mysql-password=abc.1234 --mysql-db=dbtest --tables=10 --table-size=1000000 --report-interval=10 --threads=1000 --time=300 cleanup

Dropping table 'sbtest2'...

Dropping table 'sbtest6'...
Dropping table 'sbtest7'...
Dropping table 'sbtest8'...
Dropping table 'sbtest9'...
Dropping table 'sbtest10'...
六、MYSQL压测附录
1、压测lua脚本
bulk_insert.lua
oltp_common.lua
oltp_delete.lua
oltp_insert.lua
oltp_point_select.lua
oltp_read_only.lua
oltp_read_write.lua
oltp_update_index.lua
oltp_update_non_index.lua
oltp_write_only.lua
select_random_points.lua
select_random_ranges.lua
2、其他重要参数
--histogram[=on|off] ##是否开启生成直方图,默认是off
--percentile=N ##调整响应时间的百分比,默认是95
--events=N ##最大的request数值,默认是0,表示无最大事件限制,别名是--max-requests=N
--db-driver=STRING ##数据库驱动mysql/oracle/pg
暂时简单的做下新版本的测试使用,后续完善压测脚本、压测结果整理...
