mysql benchmark基准测试

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）

 

mac上的用法：

一、安装 

brew install sysbench

 

二、先在mysql上创建一个专门的测试数据库，比如test

 

三、利用sysbench先生成测试数据 

sysbench --test=oltp --oltp-table-size=5000000 --oltp-table-name=t_test --mysql-table-engine=innodb --mysql-host=localhost --mysql-db=test --mysql-user=root --mysql-password=*** prepare

上面这一堆的意思，是在本机localhost的test数据库的t_test中创建500万条测试数据，表的数据库引擎为innodb.

tips:如果想知道还有哪些参数可用，可输入命令

sysbench --test=oltp help

　　 

四、运行测试

sysbench --test=oltp --oltp-table-size=5000000 --oltp-table-name=t_test --mysql-table-engine=innodb --mysql-host=localhost --mysql-db=test --mysql-user=root --mysql-password=*** run

最后一个prepare改成run就行了，测试完后，会输出类似以下结果：

sysbench 0.4.12:  multi-threaded system evaluation benchmark

No DB drivers specified, using mysql
Running the test with following options:
Number of threads: 1

Doing OLTP test.
Running mixed OLTP test
Using Special distribution (12 iterations,  1 pct of values are returned in 75 pct cases)
Using "BEGIN" for starting transactions
Using auto_inc on the id column
Maximum number of requests for OLTP test is limited to 10000
Threads started!
Done.

OLTP test statistics:
    queries performed:
        read:                            140000
        write:                           50000
        other:                           20000
        total:                           210000
    transactions:                        10000  (514.48 per sec.)
    deadlocks:                           0      (0.00 per sec.)
    read/write requests:                 190000 (9775.14 per sec.)
    other operations:                    20000  (1028.96 per sec.)

Test execution summary:
    total time:                          19.4371s
    total number of events:              10000
    total time taken by event execution: 19.3581
    per-request statistics:
         min:                                  1.65ms
         avg:                                  1.94ms
         max:                                 13.48ms
         approx.  95 percentile:               2.34ms

Threads fairness:
    events (avg/stddev):           10000.0000/0.00
    execution time (avg/stddev):   19.3581/0.00

一般我们比较关心：

    transactions:                        10000  (514.48 per sec.)

    read/write requests:                 190000 (9775.14 per sec.)

这代表每秒能处理的事务数，以及每秒的读写次数。

 

五、清理测试数据

sysbench --test=oltp --oltp-table-size=5000000 --oltp-table-name=t_test --mysql-table-engine=innodb --mysql-host=localhost --mysql-db=test --mysql-user=root --mysql-password=*** cleanup

最后一个换成cleanup即可。　

 

春晚实在太无聊了，还不如写二行代码有意思，祝各位园友猴年大吉，身体健康，心想事成！
