可以使用mysqlslap --help来显示使用方法：
Default options are read from the following files in the given order:
/etc/mysql/my.cnf /etc/my.cnf ~/.my.cnf
--concurrency代表并发数量，多个可以用逗号隔开，concurrency=10,50,100, 并发连接线程数分别是10、50、100个并发。
--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。
--debug-info 代表要额外输出CPU以及内存的相关信息。
--number-int-cols ：创建测试表的 int 型字段数量
--auto-generate-sql-add-autoincrement : 代表对生成的表自动添加auto_increment列，从5.1.18版本开始
--number-char-cols 创建测试表的 char 型字段数量。
--create-schema 测试的schema，MySQL中schema也就是database。
--query 使用自定义脚本执行测试，例如可以调用自定义的一个存储过程或者sql语句来执行测试。
--only-print 如果只想打印看看SQL语句是什么，可以用这个选项。

mysqlslap -umysql -p123 --concurrency=100 --iterations=1 --auto-generate-sql --auto-generate-sql-add-autoincrement --auto-generate-sql-load-type=mixed --engine=myisam --number-of-queries=10 --debug-info

或：

指定数据库和sql语句:

mysqlslap -h192.168.0.129 -P4040 --concurrency=100 --iterations=1 --create-schema='test' --query='select * from test;' --number-of-queries=10 --debug-info -umysql -p123

要是看到底做了什么可以加上：--only-print

#h主机 u用户名 p密码 P端口号 create-schema 要查询的数据库名称 query查询的SQL语句 concurrency并发数量 iterations迭代次数 engine支持的引擎

mysqlslap -h192.168.0.129 -uroot -p123456 -P3306 --create-schema='tps_live' --query='/usr/local/src/testSql1.sql' --concurrency=10,20,30 --iterations=2 --engine=myisam,innodb
