安装
# 安装sysbench
brew install sysbench -g
支持的测试模式
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
测试数据库(OLTP基准测试)
# 准备数据库
mysqladmin create test
# 准备测试数据
# 准备十万条测试数据的量
sysbench --test=/usr/local/Cellar/sysbench/1.0.17/share/sysbench/oltp_common.lua --table-size=100000 --mysql-host=k8s-n1 --mysql-port=3307 --mysql-user=root --mysql-password=123456 --mysql-db=test prepare
# 进行插入性能测试
# 插入10万条数据,8个线程执行,每10秒中报告一次
sysbench --test=/usr/local/Cellar/sysbench/1.0.17/share/sysbench/oltp_insert.lua --table-size=100000 --mysql-host=k8s-n1 --mysql-port=3307 --mysql-user=root --mysql-password=123456 --mysql-db=test --threads=8 --max-requests=0 --report-interval=10 --time=300 run
# 结果解读
Running the test with following options:
Number of threads: 8
Report intermediate results every 10 second(s)
Random number generator seed is 0 and will be ignored
