MySQL性能测试工具之mysqlslap

mysqlslap是mysql自带的基准测试工具,优点:查询数据,语法简单,灵活容易使用.该工具可以模拟多个客户端同时并发的向服务器发出查询更新,给出了性能测试数据而且提供了多种引擎的性能比较.msqlslap为mysql性能优化前后提供了直观的验证依据,建议系统运维和DBA人员应该掌握一些常见的压力测试工具,才能准确的掌握线上数据库支撑的用户流量上限及其抗压性等问题。

1.工具详细参数

–help      显示帮助

–concurrency      代表并发数量,多个可以用逗号隔开

–engines            测试的引擎,多个用分隔符隔开

–iterations          运行这些测试多少次

–auto-generate-sql      系统自己生成的SQL脚本来测试

–auto-generate-sql-load-type    测试的是读还是写还是两者混合的（read,write,update,mixed）

–number-of-queries                  总共要运行多少次查询

–debug-info                              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        生成的表自动添加auto_increment列

–number-char-cols                  测试表的 char 型字段数量

–create-schema              测试的database

–query                          用自定义脚本执行测试

–only-print                            如果只想打印看看SQL语句是什么,以用这个选项

2.测试实例(单个并发)

[root@node2 bin]# ./mysqlslap -uroot -psystem –concurrency=100 –iterations=1 –auto-generate-sql –auto-generate-sql-load-type=mixed –auto-generate-sql-add-autoincrement –engine=myisam –number-of-queries=10 –debug-info 
Warning: Using a password on the command line interface can be insecure.
