清除测试数据：
sysbench fileio --file-total-size=40G cleanup
OLTP基准测试
OLTP基准测试模拟了一个简单的事务处理系统的工作负载。若要对数据库性能进行测试就要使用OLTP相关的脚本。
在/usr/share/sysbench/目录下有相关的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
对于未知的测试参数，可以通过 sysbench scripts-name help 来查看。
创建测试数据：
sysbench oltp_common --table-size=1000000 --db-driver=mysql \
--mysql-db=test --mysql-user=root --mysql-password=123456 prepare
Creating table 'sbtest1'...
Inserting 1000000 records into 'sbtest1'
Creating a secondary index on 'sbtest1'...
执行run命令进行测试：（只读）
sysbench oltp_read_only --table-size=1000000 --db-driver=mysql \
--mysql-db=test --mysql-user=root --mysql-password=123456 --time=60 --max-requests=0 --threads=8 run
#测试结果
