mysqlslap是一个mysql官方提供的压力测试工具。以下是比较重要的参数：

–defaults-file，配置文件存放位置

–concurrency，并发数

–engines，引擎

–iterations，迭代的实验次数

–socket，socket文件位置

自动测试：

–auto-generate-sql，自动产生测试SQL

–auto-generate-sql-load-type，测试SQL的类型。类型有mixed，update，write，key，read。

–number-of-queries，执行的SQL总数量

–number-int-cols，表内int列的数量

–number-char-cols，表内char列的数量

例如：

shell>mysqlslap –defaults-file=/u01/mysql1/mysql/my.cnf –concurrency=50,100 –iterations=1 –number-int-cols=4 –auto-generate-sql –auto-generate-sql-load-type=write –engine=myisam –number-of-queries=200 -S/tmp/mysql1.sock
