Linux 性能測試工具 sysbench 的安裝與簡單使用

一背景

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。
sysbench 支持如下幾種測試模式：mysql

一、CPU運算性能
二、內存分配及傳輸速度
三、磁盤IO性能
四、POSIX線程性能
五、互斥性測試
六、數據庫性能(OLTP基準測試)。目前sysbench主要支持 MySQL,PostgreSQL 等幾種數據庫。

二實驗環境

2.1 操做系統

[gysl@gysl-DevOps ~]$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

2.2 其餘配置

安裝EPEL，安裝方法以前的文章有介紹。git

三安裝

安裝命令以下：github

[gysl@gysl-DevOps ~]$ sudo yum -y install sysbench
