使用mysqlslap进行MySQL压力测试

MySQL从5.1.4版开始带有一个压力测试工具mysqlslap，通过模拟多个并发客户端访问mysql来执行测试，使用起来非常的简单。通过mysqlslap –help可以获得可用的选项，这里列一些主要的参数，更详细的说明参考官方手册。

  1. --auto-generate-sql, -a
  2. 自动生成测试表和数据
  3.  
  4. --auto-generate-sql-load-type=type
  5. 测试语句的类型。取值包括：read，key，write，update和mixed(默认)。
  6.  
  7. --number-char-cols=N, -x N
  8. 自动生成的测试表中包含多少个字符类型的列，默认1
  9.  
  10. --number-int-cols=N, -y N
  11. 自动生成的测试表中包含多少个数字类型的列，默认1
  12.  
  13. --number-of-queries=N
  14. 总的测试查询次数(并发客户数×每客户查询次数)
  15.  
  16. --query=name,-q
  17. 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。
  18.  
  19. --create-schema
  20. 测试的schema，MySQL中schema也就是database
  21.  
  22. --commint=N
  23. 多少条DML后提交一次
  24.  
  25. --compress, -C
  26. 如果服务器和客户端支持都压缩，则压缩信息传递
  27.  
  28. --concurrency=N, -c N
  29. 并发量，也就是模拟多少个客户端同时执行select。可指定多个值，以逗号或者–delimiter参数指定的值做为分隔符
  30.  
  31. --engine=engine_name, -e engine_name
  32. 创建测试表所使用的存储引擎，可指定多个，用分隔符隔开。
  33.  
  34. --iterations=N, -i N
  35. 测试执行的迭代次数
  36.  
  37. --detach=N
  38. 执行N条语句后断开重连
  39.  
  40. --debug-info, -T
  41. 打印内存和CPU的信息
  42.  
  43. --only-print
  44. 只打印测试语句而不实际执行
  45.  
  46. --defaults-file
  47. 配置文件存放位置
  48.  
  49. --socket＝name,-S
  50. 指定socket文件位置

一些实例
　　用自动生成的测试数据进行测试，且只打印实际的测试过程。

  10. SELECT intcol1,charcol1 FROM t1;
  11. INSERT INTO t1 VALUES (73673339,'BN3152Gza4GW7atxJKACYwJqDbFynLxqc0kh30YTwgz3FktQ43XTrqJ4PQ25frn7kXhfXD8RuzN1j8Rf3y8ugKy6es3IbqPJM6ylCyD6xS7YcQCfHKZxYNvB7yTahm');
