mysqlslap 使用总结
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 [root@davy libmysql]# mysqlslap -a --concurrency=50,100 --number-of-queries=1000 2 Benchmark 3 Average number of seconds to run all queries: 0.148 seconds 4 Minimum number of seconds to run all queries: 0.148 seconds 5 Maximum number of seconds to run all queries: 0.148 seconds 6 Number of clients running queries: 50 7 Average number of queries per client: 20 8 9 Benchmark 10 Average number of seconds to run all queries: 0.246 seconds 11 Minimum number of seconds to run all queries: 0.246 seconds 12 Maximum number of seconds to run all queries: 0.246 seconds 13 Number of clients running queries: 100 14 Average number of queries per client: 10 15 16 [root@Betty libmysql]#
3. 增加 --debug-info 选项，可以输出内存和CPU信息

5. 可以 针对远程主机上的 mysql 进行测试
1 [root@davy Shell]# mysqlslap -a --concurrency=50,100 --number-of-queries=1000 -h 172.18.121.99 -P 3306 -p 2 Enter password: 3 Benchmark 4 Average number of seconds to run all queries: 2.009 seconds 5 Minimum number of seconds to run all queries: 2.009 seconds 6 Maximum number of seconds to run all queries: 2.009 seconds 7 Number of clients running queries: 50 8 Average number of queries per client: 20 9 10 Benchmark 11 Average number of seconds to run all queries: 4.519 seconds 12 Minimum number of seconds to run all queries: 4.519 seconds 13 Maximum number of seconds to run all queries: 4.519 seconds 14 Number of clients running queries: 100 15 Average number of queries per client: 10
6. 使用 --only-print 选项，可以查看 mysqlslap 在测试过程中如何执行的 sql 语句。在这种方式下，仅会对数据库进行模拟操作。如下显示的自动产生测试表和数据的情况下，mysqlslap 的执行过程： 创建一个临时的库 mysqlslap ，并在测试结束是会将其删除。

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 [root@davy ~]# mysqlslap --delimiter=";" --create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" --query="SELECT * FROM a" --concurrency=50 --iterations=200 2 Benchmark 3 Average number of seconds to run all queries: 0.005 seconds 4 Minimum number of seconds to run all queries: 0.003 seconds 5 Maximum number of seconds to run all queries: 0.007 seconds 6 Number of clients running queries: 50 7 Average number of queries per client: 1
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 [root@davy ~]# mysqlslap --concurrency=5 --iterations=20 --number-int-cols=2 --number-char-cols=3 --auto-generate-sql 2 3 Benchmark 4 Average number of seconds to run all queries: 0.025 seconds 5 Minimum number of seconds to run all queries: 0.012 seconds 6 Maximum number of seconds to run all queries: 0.084 seconds 7 Number of clients running queries: 5 8 Average number of queries per client: 0
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=";"
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。
