sysbench壓測自裝MySQL資料庫

阿新 • • 發佈：2020-02-16

壓測準備

測試機器

  • 2vCPUs | 4GB | s6.large.2 CentOS 7.6 64bit

    建立測試庫

create database test_db 
character set utf8mb4 collate utf8mb4_bin;

下載sysbench

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
sudo yum -y install sysbench
sysbench --version
sysbench 1.0.19

準備測試表

sysbench 
//基於mysql的驅動去連線mysql資料庫
--db-driver=mysql 
//連續訪問300秒
--time=300 
//10個執行緒模擬併發訪問
--threads=10 
//每隔1秒輸出一下壓測情況
--report-interval=1 
//本機
--mysql-host=127.0.0.1 
//埠號：3306
--mysql-port=3306 
//測試使用者
--mysql-user=root 
//測試密碼
--mysql-password=******* 
//測試資料庫
--mysql-db=test_db 
//模擬新建20個表
--tables=20 
//100萬條資料 執行oltp資料庫的讀寫測試
--table_size=1000000 oltp_read_write 
//參照這個命令的設定去構造出來我們需要的資料庫裡的資料
//自動建立20個測試表，每個表裡建立100萬條測試資料
--db-ps-mode=disable prepare

執行命令之後：
