利用sysbench很容易对mysql做性能基准测试(当然这个工具很强大,除了测试主流数据库性能,还能测试其它方面,详情自己看官网项目文档)
Linux上的用法:
一、安装
yum install -y sysbench
二、先在mysql上创建一个专门的测试数据库,比如sbtest
FATAL: unable to connect to MySQL server, aborting...
FATAL: error 1049: Unknown database 'sbtest'
FATAL: failed to connect to database server!
...
错误提示说:mysql连接不上, sbtest库没找到。 需要创建一个sbtest库!
sysbench /usr/share/sysbench/tests/include/oltp_legacy/oltp.lua --db-driver=mysql --mysql-host=192.168.60.165 --mysql-port=18604 --mysql-user=root --mysql-password=cc.123 --oltp-test-mode=complex --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 prepare
--test=tests/db/oltp.lua 表示调用/db/oltp.lua 脚本进行模式测试
--oltp_tables_count=10表示会生成10个测试表
--oltp-table-size=100000表示每个测试表填充数据量为100000
--rand-init=on 表示每个测试表都是用随机数据来填充的
真实测试场景中,数据表建议不低于10个,单表数据量不低于500万行,当然了,要视服务器硬件配置而定。如果是配备了SSD或者PCIE SSD这种高IOPS设备的话,则建议单表数据量最少不低于1亿行。
真实测试场景中,建议持续压测时长不小于30分钟,否则测试数据可能不具参考意义。
三、利用sysbench先生成测试数据
sysbench /usr/share/sysbench/tests/include/oltp_legacy/oltp.lua --db-driver=mysql --mysql-host=192.168.60.165 --mysql-port=18604 --mysql-user=root --mysql-password=cc.123 --oltp-test-mode=complex --oltp-tables-count=10 --oltp-table-size=100000 --threads=10 --time=120 --report-interval=10 run >> /home/mysysbench.log

测试完成执行cleanup
测试结束后,记得执行cleanup,以确保测试所产生的文件都已删除
