mysql之 mysql数据库压力测试工具(mysqlslap)
mysqlslap是从MySQL的5.1.4版开始就开始官方提供的压力测试工具。通过模拟多个并发客户端并发访问MySQL来执行压力测试,同时提供了较详细的SQL执行数据性能报告,并且能很好的对比多个存储引擎(MyISAM,InnoDB等)在相同环境下的相同并发压力下的性能差别。

--create-schema 代表自定义的测试库名称,测试的schema,MySQL中schema也就是database。
(没指定使用哪个数据库时,可能会遇到错误mysqlslap: Error when connecting to server: 1049 Unknown database
'mysqlslap'
)
--query=name,-q 使用自定义脚本执行测试(可以是SQL字符串或脚本),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。
--create 创建表所需的SQL(可以是SQL字符串或脚本)
--concurrency=N, -c N 表示并发量,也就是模拟多少个客户端同时执行query。可指定多个值,以逗号或者--delimiter参数指定的值做为分隔符。例如:--concurrency=100,200,500(分别执行100、200、500个并发)。
--iterations=N, -i N 测试执行的迭代次数,代表要在不同的并发环境中,各自运行测试多少次;多次运行以便让结果更加准确。
--number-of-queries=N 总的测试查询次数(并发客户数×每客户查询次数)
--engine=engine_name, -e engine_name 代表要测试的引擎,可以有多个,用分隔符隔开。例如:--engine=myisam,innodb,memory。
--auto-generate-sql, -a 自动生成测试表和数据,表示用mysqlslap工具自己生成的SQL脚本来测试并发压力。
--auto-generate-sql-load-
type
=
type
测试语句的类型。代表要测试的环境是读操作还是写操作还是两者混合的。取值包括:
read
(scan tables), write (insert into tables), key (
read
primary keys), update (update primary keys), or mixed (half inserts, half scanning selects). 默认值是:mixed.
--auto-generate-sql-add-auto-increment 代表对生成的表自动添加auto_increment列,从5.1.18版本开始支持。
--number-char-cols=N, -x N 自动生成的测试表中包含多少个字符类型的列,默认1
--number-int-cols=N, -y N 自动生成的测试表中包含多少个数字类型的列,默认1
--commint=N 多少条DML后提交一次。
--compress, -C 如果服务器和客户端支持都压缩,则压缩信息传递。
--only-print 只打印测试语句而不实际执行。
--detach=N 执行N条语句后断开重连。
--debug-info, -T 打印内存和CPU的相关信息。
1. 创建schema、table、test data 等 (在MySQL中,schema就是database);
2. 运行负载测试,可以使用多个并发客户端连接;
3. 测试环境清理(删除创建的数据、表等)。
