標杆:: MySQL中,CPU,文件I / O,內存:: Sysbench與Apache的基準

Original Post: http://anothermysqldba.blogspot.com/2013/05/benchmarking-mysql-cpu-file-io-memory.html


決定你想用哪一種工具:
我將使用Sysbench的這個例子:
首先下載sysbench
安裝:
SysBench手冊
查看你的選擇:
#sysbench - 測試= OLTP幫助

編譯測試:
FILEIO - 文件I / O測試
CPU - CPU性能測試
內存 - 功能速度測試
線程 - 線程子系統性能測試
互斥 - 互斥性能測試
OLTP - OLTP測試

命令:準備運行清理的幫助版本

下面一些例子:

sysbench期望找到sbtest數據庫,所以一定要確保和創造,首先定義你喜歡什麼樣的數據庫。
  • sysbench - 測試= OLTP幫助| grep的sbtest
    - OLTP表名= STRING測試表名稱[sbtest]
    - mysql用戶的= STRING MySQL的用戶[sbtest]
    - MYSQL-DB = STRING MySQL數據庫名稱[sbtest]

#sysbench的 - 測試= OLTP - MySQL的主機=本地主機 - MySQL的超級用戶身份 - MySQL的密碼= [<密碼HERE> - mysql的表引擎= InnoDB的準備

#sysbench的mysql的密碼 - 測試= OLTP - MySQL的主機=本地主機 - MySQL的超級用戶身份 - = <password HERE> - mysql的表引擎InnoDB的 - 號線程= 25運行

然後留意你的結果以及數據庫的測試運行。



Apache的基準和| |
WWW ::機械化::火狐

關鍵在這裡帶走的是使用這些工具進行基準測試您的應用程序和過程,不只是一個單一的架構因素。

例如,如果你期望有一個小時20000用戶填寫您的Web表單,那麼你應該基準您的應用程序來處理。 您可以使用上方的工具,模仿的職位只是一個例子,通過令牌,然後測試代碼,在您的應用程序上。 這樣的測試,然後將測試的代碼庫,並與合適的日誌記錄的地方(你也可以打開一個令牌),你可以測試以及開發人員,DBA和系統如何建。

的概念很簡單的例子:

如果你可以打開網址elinks的基準。

elinks http://www.google.com/search?ie=ISO-8859-1\&hl=en\&source=hp\&q=mysql

# ab -n 10 -c 2 http://www.google.com/search?ie=ISO-8859-1\&hl=en\&source=hp\&q=mysql 

當然,你會執行此對您的系統在一個更高的水平,以測試應用程序如何響應。
