sysbench 項目測試過程與分析
1、sysbench項目測試過程mysql
1.1 sysbench基準壓測 my.cnflinux
自動生成MySQL的配置文件：http://imysql.cn/my_cnf_generatorios

1.2 sysbench 測試準備sql
測試環境數據庫
主機、CPU、內存、RAID、硬盤、文件系統、內存、MySQL、sysbenchvim
2. 壓測基準值bash
多少張表，每張表多少數據量，測試腳本，測試多少時間，最大請求數多少，併發線程數，生成多大數量服務器
1.3 進行sysbench OLTP 測試-混合讀寫session
準備數據多線程

2、sysbench 其它類型測試
2.1 只讀（從庫查詢）

rndrd 隨機讀
rndwr 隨機寫
rndrw 隨機讀寫
3.1 準備 IO 測試文件：執行以下命令，生成 16 個文件，用於本次測試
