      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。

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。
[root@Betty libmysql]# mysqlslap -a --only-print

7. 实际测试中的复杂情况。
使用 --defaults-file 选项,指定从配置文件中读取选项配置。
使用 --number-int-cols 选项,指定表中会包含 4 个 int 型的列。
使用 --number-char-cols 选项,指定表中会包含 35 个 char 型的列。
使用 --engine 选项,指定针对何种存储引擎进行测试。

8. 使用存储过程进行测试。



========== 我是分割线 =============

mysqlslap 运行分三个阶段:
  1. 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;
  2. 进行负载测试。这个阶段使用多客户端连接;
  3. 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):
[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):
[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:
[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。

请教一下 --debug-info 被禁用了 是怎么回事!

楼主能对测试的结果,信息能详细的说明吗? 那些值说明数据库的性能良好!
