mysqlslap 可以用于模拟服务器的负载,并输出计时信息。其被包含在 MySQL 5.1 的发行包中。测试时,可以指定并发连接数,可以指定 SQL 语句。如果没有指定 SQL 语句,mysqlslap 会自动生成查询 schema 的 SELECT 语句。

2. 以自动生成测试表和数据的形式,分别模拟 50 和 100 个客户端并发连接处理 1000 个 query 的情况。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | [root@Betty libmysql]# mysqlslap -a --concurrency=50,100 --number-of-queries=1000 Benchmark Average number of seconds to run all queries: 0.148 seconds Minimum number of seconds to run all queries: 0.148 seconds Maximum number of seconds to run all queries: 0.148 seconds Number of clients running queries: 50 Average number of queries per client: 20 Benchmark Average number of seconds to run all queries: 0.246 seconds Minimum number of seconds to run all queries: 0.246 seconds Maximum number of seconds to run all queries: 0.246 seconds Number of clients running queries: 100 Average number of queries per client: 10 [root@Betty libmysql]# |
3. 增加 --debug-info 选项,可以输出内存和CPU信息。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | [root@Betty libmysql]# mysqlslap -a --concurrency=50,100 --number-of-queries=1000 --debug-info Benchmark Average number of seconds to run all queries: 0.202 seconds Minimum number of seconds to run all queries: 0.202 seconds Maximum number of seconds to run all queries: 0.202 seconds Number of clients running queries: 50 Average number of queries per client: 20 Benchmark Average number of seconds to run all queries: 0.193 seconds Minimum number of seconds to run all queries: 0.193 seconds Maximum number of seconds to run all queries: 0.193 seconds Number of clients running queries: 100 Average number of queries per client: 10 User time 0.09, System time 0.05 Maximum resident set size 7848, Integral resident set size 0 Non-physical pagefaults 4221, Physical pagefaults 0, Swaps 0 Blocks in 0 out 0, Messages in 0 out 0, Signals 0 Voluntary context switches 7314, Involuntary context switches 1400 |

8. 使用存储过程进行测试。
略
========== 我是分割线=============
mysqlslap 运行分三个阶段:
创建 schema,table 和任何用来测试的已经存储了的程序和数据。这个阶段使用单客户端连接;
进行负载测试。这个阶段使用多客户端连接;
清除(断开连接,删除指定表)。这个阶段使用单客户端连接。
例子:
a. 提供你自己的创建 SQL 语句和查询 SQL 语句,有 50 个客户端查询,每个查询 200 次(在单行上输入命令):
1 2 3 4 5 6 7 8 | [root@Betty ~]# mysqlslap --delimiter=";" --create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" --query="SELECT * FROM a" --concurrency=50 --iterations=200 Benchmark Average number of seconds to run all queries: 0.005 seconds Minimum number of seconds to run all queries: 0.003 seconds Maximum number of seconds to run all queries: 0.007 seconds Number of clients running queries: 50 Average number of queries per client: 1 [root@Betty ~]# |
b. 让 mysqlslap 创建查询的 SQL 语句,使用的表有 2 个 INT 行和 3 个 VARCHAR 行。使用 5 个客户端,每一个查询 20 次!不要创建表或插入数据。(换言之,用之前测试的模式和数据):
1 2 3 4 5 6 7 8 | [root@Betty ~]# mysqlslap --concurrency=5 --iterations=20 --number-int-cols=2 --number-char-cols=3 --auto-generate-sql Benchmark Average number of seconds to run all queries: 0.025 seconds Minimum number of seconds to run all queries: 0.012 seconds Maximum number of seconds to run all queries: 0.084 seconds Number of clients running queries: 5 Average number of queries per client: 0 [root@Betty ~]# |
c. 告诉程序从指定的 create.sql 文件去加载 create,insert 和查询等 SQL 语句。该文件有多个表的 create 和insert 语句, 它们都是通过“;”分隔开的。query.sql 文件则有多个查询语句, 分隔符也是“;”。执行所有的加载语句,然后通过查询文件执行所有的查询语句,分别在 5 个客户端上每个执行 5 次:
1 | [root@Betty ~]# mysqlslap --concurrency=5 --iterations=5 --query=query.sql --create=create.sql --delimiter=";" |
========== 我是分割线 =============
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。
