一、描述

漏掃發現MySQL有低風險漏洞，自己寫方案、自己做測試、自己更新。

版本：MySQL 5.7.25 更新到MySQL 5.7.28最新版本。

架構：主從架構

二、更新流程

1、下載下傳最新版資料庫軟體MySQL 5.7.28

2、上傳到指定目錄

3、備份資料庫軟體、資料庫資料目錄、my.cnf

4、解壓縮資料庫軟體到指定路徑

5、關閉備庫

6、使用新版軟體啟動備庫，mysqld_safe &

7、登入備庫，發現版本已更新，使用mysql_upgrade指令更新系統資料庫

8、無報錯的話，重新開機備庫。

9、主庫按照備庫流程走一遍

10、最後确認主備庫是否一緻
