Hi @armstrong hao 

Create a New Database in MySQL & connect with Confluence (Remove the confluence.cfg.xml File in Home directory and restart the Application)

Reference here

https://confluence.atlassian.com/doc/database-setup-for-mysql-128747.html

(Remember to download the driver)

If you are running MySQL 5.6 or 5.7

CREATE USER 'confuser'@'%' IDENTIFIED BY 'Admin1234.';
CREATE DATABASE confdb CHARACTER SET utf8 COLLATE utf8_bin;
GRANT ALL ON confdb.* TO 'confuser'@'%';

If you are running MySQL 8

CREATE USER 'confuser'@'%' IDENTIFIED BY 'Admin1234.';
CREATE DATABASE confdb CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
GRANT ALL ON confdb.* TO 'confuser'@'%';

Let me know if this works for you

Thanks,
Pramodh
