sysbench对MySQL的压测,使用sysbench压测磁盘io

QPS - query per second
TPS - transaction per second 不是特别关注,每个业务场景中事务标准是不一样的

Ⅰ、sysbench测试框架

Ⅱ、常用测试脚本

[root@VM_42_63_centos lua]# pwd
/usr/local/src/sysbench-master/src/lua
[root@VM_42_63_centos lua]# ll *.lua
-rwxr-xr-x 1 root root  1446 Jun 27 02:35 bulk_insert.lua

-rwxr-xr-x 1 root root  1440 Jun 27 02:35 oltp_write_only.lua

-rwxr-xr-x 1 root root  2132 Jun 27 02:35 select_random_ranges.lua

Ⅲ、开搞

这个老版本好像有参数设置热数据的量什么的,现在最新版本不知道咋搞,就先将就直接弄吧,不管了

准备数据
[root@VM_42_63_centos lua]# sysbench --mysql-host=127.0.0.1 --mysql-port=3307 --mysql-db=sbtest --tables=10 --table-size=10000 --mysql-user=root --mysql-password=123 oltp_update_index.lua prepare
sysbench 1.1.0 (using bundled LuaJIT 2.1.0-beta3)

Creating table ‘sbtest1‘...
Inserting 10000 records into ‘sbtest1‘
Creating a secondary index on ‘sbtest1‘...
Creating table ‘sbtest2‘...
Inserting 10000 records into ‘sbtest2‘
Creating a secondary index on ‘sbtest2‘...
Creating table ‘sbtest3‘...

...

开始测试
[root@VM_42_63_centos lua]# sysbench oltp_update_index.lua --mysql-host=127.0.0.1 --mysql-port=3307 --mysql-user=root --mysql-password=123 --threads=10 --time=120 --report-interval=10 run
sysbench 1.1.0 (using bundled LuaJIT 2.1.0-beta3)

Running the test with following options:
Number of threads: 10
Report intermediate results every 10 second(s)
Initializing random number generator from current time


Initializing worker threads...

看结果,这里就不解释了,比较简单,随便看看就好
