阿里云centos mysql数据库远程链接

1.  阿里云安全组端口开通 mysql port

2. 数据库用户默认host是localhost， 修改%

mysql> select user, host from mysql.user;
+------------------+-----------+
| user             | host      |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| root             | localhost |
+------------------+-----------+
4 rows in set (0.00 sec)
mysql> update mysql.user set host='%' where user = 'root' and host='localhost';

mysql> FLUSH PRIVILEGES;

3. 可能须要这一步：

firewall-cmd --permanent --zone=public --add-port=3306/tcp
firewall-cmd --reload

 

作个记录，省得忘记。
