1. 首先要查詢到mysql的安裝地址
show variables like 'datadir';

+---------------+-----------------+
| Variable_name | Value |
+---------------+-----------------+
| datadir | /var/lib/mysql/ |
+---------------+-----------------+
1 row in set (0.00 sec)

//然後通過mysql生成一個uuid進行記錄等會用於修改
select uuid()

+--------------------------------------+
| uuid() |
+--------------------------------------+
| 2674149f-5083-11e8-be4b-080027a1f331 |
+--------------------------------------+


2. 然後進入datadir目錄
cd /var/lib/mysql/
vi auto.cnf
//修改server-uuid
