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。

mysqlslap的运行有如下3个步骤：

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）。

案例：

[root@mysql ~]# mysqlslap -a --concurrency=50,100 --number-of-queries 1000 --auto-generate-sql-add-autoincrement --number-char-cols=10 --number-int-cols=5 -poracle

Warning: Using a password on the command line interface can be insecure.
