MySQL 壓測工具 sysbench 安裝及使用

sysbench是一款開源的多線程性能測試工具，能夠執行CPU/內存/線程/IO/數據庫等方面的性能測試。數據庫目前支持MySQL/Oracle/PostgreSQL，後續的版本oltp測試主要結合了lua腳本，不須要修改源碼，經過自定義lua腳本就能夠實現不一樣業務類型的測試；

總結起來sysbench的缺點就是，模擬的表結構太簡單，不像tpcc-mysql那樣完整的事務系統。但對於性能壓測對比仍是頗有用的，由於sysbench使用的環境參數限制是同樣的。

安裝

經過git上的源碼進行編譯安裝過程（須要聯網）

yum install -y git

yum install -y gcc gcc-c++ automake make libtool

克隆sysbench源碼

OLTP測試
對於mysql的OLTP測試，和file同樣，一樣須要經歷prepare,run,cleanup三個階段。prepare階段會在數據庫中指定張和指定行數的表，默認表在sbtest架構下，表名爲sbtestN，數據庫sbtest須要手動在數據庫中建立不然會報錯。
經過調用不一樣的lua腳本測試不一樣業務模式下的數據庫性能，也可自定義lua腳本進行測試。
