用mysqlslap对MySQL进行压力测试

MySQL5.1地的确提供了好多有力的工具来帮助我们DBA进行数据库管理。
现在看一下这个压力测试工具mysqlslap.
关于他的选项手册上以及--help介绍的很详细。
我解释一下一些常用的选项。
这里要注意的几个选项:
--concurrency代表并发数量,多个可以用逗号隔开,当然你也可以用自己的分隔符隔开,这个时候要用到--delimiter开关。
--engines代表要测试的引擎,可以有多个,用分隔符隔开。
--iterations代表要运行这些测试多少次。
--auto-generate-sql 代表用系统自己生成的SQL脚本来测试。
--auto-generate-sql-load-type 代表要测试的是读还是写还是两者混合的(read,write,update,mixed)
--number-of-queries 代表总共要运行多少次查询。每个客户运行的查询数量可以用查询总数/并发数来计算。比如倒数第二个结果2=200/100。
--debug-info 代表要额外输出CPU以及内存的相关信息。
--number-int-cols 代表示例表中的INTEGER类型的属性有几个。
--number-char-cols 意思同上。
--create-schema 代表自己定义的模式(在MySQL中也就是库)。
--query 代表自己的SQL脚本。
--only-print 如果只想打印看看SQL语句是什么,可以用这个选项。
现在来看一些我测试的例子。
1、用自带的SQL脚本来测试。
MySQL版本为5.1.23
Benchmark
Running for engine myisam
Average number of seconds to run all queries: 0.063 seconds
Minimum number of seconds to run all queries: 0.063 seconds
Maximum number of seconds to run all queries: 0.063 seconds
Number of clients running queries: 50
Average number of queries per client: 4
Benchmark
Running for engine myisam
Average number of seconds to run all queries: 0.070 seconds
Minimum number of seconds to run all queries: 0.070 seconds
Maximum number of seconds to run all queries: 0.070 seconds
Number of clients running queries: 100
Average number of queries per client: 2
Benchmark
Running for engine myisam
Average number of seconds to run all queries: 0.092 seconds
Minimum number of seconds to run all queries: 0.092 seconds
Maximum number of seconds to run all queries: 0.092 seconds
Number of clients running queries: 200
Average number of queries per client: 1
Benchmark
Running for engine innodb
Average number of seconds to run all queries: 0.115 seconds
Minimum number of seconds to run all queries: 0.115 seconds
Maximum number of seconds to run all queries: 0.115 seconds
Number of clients running queries: 50
Average number of queries per client: 4
Benchmark
Running for engine innodb
Average number of seconds to run all queries: 0.134 seconds
Minimum number of seconds to run all queries: 0.134 seconds
Maximum number of seconds to run all queries: 0.134 seconds
Number of clients running queries: 100
Average number of queries per client: 2
Benchmark
Running for engine innodb
Average number of seconds to run all queries: 0.192 seconds
Minimum number of seconds to run all queries: 0.192 seconds
Maximum number of seconds to run all queries: 0.192 seconds
Number of clients running queries: 200
Average number of queries per client: 1
User time 0.06, System time 0.15
Maximum resident set size 0, Integral resident set size 0
Non-physical pagefaults 5803, Physical pagefaults 0, Swaps 0
Blocks in 0 out 0, Messages in 0 out 0, Signals 0
Voluntary context switches 8173, Involuntary context switches 528
我来解释一下结果的含义。
拿每个引擎最后一个Benchmark示例。
对于INNODB引擎,200个客户端同时运行这些SQL语句平均要花0.192秒。相应的MYISAM为0.092秒。
2、用我们自己定义的SQL 脚本来测试。
这些数据在另外一个MySQL实例上。版本为5.0.45
先看一下这两个表的相关数据。
1)、总记录数。
2)、总列数。
3)、调用的存储过程
4)、我们用mysqlslap来测试
以下得这个例子代表用mysqlslap来测试并发数为25,50,100的调用存储过程,并且总共调用5000次。

Benchmark
Average number of seconds to run all queries: 3.507 seconds
Minimum number of seconds to run all queries: 3.507 seconds
Maximum number of seconds to run all queries: 3.507 seconds
Number of clients running queries: 25
Average number of queries per client: 200
平均每个并发运行200个查询用了3.507秒。
Benchmark
Average number of seconds to run all queries: 3.742 seconds
Minimum number of seconds to run all queries: 3.742 seconds
Maximum number of seconds to run all queries: 3.742 seconds
Number of clients running queries: 50
Average number of queries per client: 100
Benchmark
Average number of seconds to run all queries: 3.697 seconds
Minimum number of seconds to run all queries: 3.697 seconds
Maximum number of seconds to run all queries: 3.697 seconds
Number of clients running queries: 100
Average number of queries per client: 50
User time 0.87, System time 0.33
Maximum resident set size 0, Integral resident set size 0
Non-physical pagefaults 1877, Physical pagefaults 0, Swaps 0
Blocks in 0 out 0, Messages in 0 out 0, Signals 0
Voluntary context switches 27218, Involuntary context switches 3100
看一下SHOW PROCESSLIST 结果
mysql> show processlist;

+------+------+--------------------+--------------------+---------+-------+--------------------+------------------------------------------------------------------------------------------------------+
55 rows in set (0.00 sec)
上面的测试语句其实也可以这样写
小总结一下。
mysqlslap对于模拟多个用户同时对MySQL发起“进攻”提供了方便。同时详细的提供了“高负荷攻击MySQL”的详细数据报告。
而且如果你想对于多个引擎的性能。这个工具再好不过了。

2、用我们自己定义的SQL 脚本来测试。
这些数据在另外一个MySQL实例上。版本为5.0.45
先看一下这两个表的相关数据。
1)、总记录数。
mysql> select table_rows as rows from information_schema.tables where table_schema='t_girl' and table_name='article'; +--------+ | rows | +--------+ | 296693 | +--------+ 1 row in set (0.01 sec) mysql> select table_rows as rows from information_schema.tables where table_schema='t_girl' and table_name='category'; +------+ | rows | +------+ | 113 | +------+ 1 row in set (0.00 sec)
2)、总列数。

3)、调用的存储过程
DELIMITER $$ DROP PROCEDURE IF EXISTS `t_girl`.`sp_get_article`$$ CREATE DEFINER=`root`@`%` PROCEDURE `sp_get_article`(IN f_category_id int, IN f_page_size int, IN f_page_no int ) BEGIN set @stmt = 'select a.* from article as a inner join '; set @stmt = concat(@stmt,'(select a.aid from article as a '); if f_category_id != 0 then set @stmt = concat(@stmt,' inner join (select cid from category where cid = ',f_category_id,' or parent_id = ',f_category_id,') as b on a.category_id = b.cid'); end if; if f_page_size >0 && f_page_no > 0 then set @stmt = concat(@stmt,' limit ',(f_page_no-1)*f_page_size,',',f_page_size); end if; set @stmt = concat(@stmt,') as b on (a.aid = b.aid)'); prepare s1 from @stmt; execute s1; deallocate prepare s1; set @stmt = NULL; END$$ DELIMITER ;
4)、我们用mysqlslap来测试

上面的测试语句其实也可以这样写
[root@localhost ~]# mysqlslap --defaults-file=/usr/local/mysql-maria/my.cnf --concurrency=25,50,100 --iterations=1 --create-schema='t_girl' --query='call sp_get_article(2,10,1);' --number-of-queries=5000 --debug-info -uroot -p -S/tmp/mysql50.sock
小总结一下。
mysqlslap对于模拟多个用户同时对MySQL发起“进攻”提供了方便。同时详细的提供了“高负荷攻击MySQL”的详细数据报告。
而且如果你想对于多个引擎的性能。这个工具再好不过了。
