MySQL允许来自多个IP地址的远程连接

Question

我知道命令

GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

这将允许来自ip 1.2.3.4的远程连接，但如果我想允许来自1.2.3.4和5.6.7.8的连接怎么办？

它看起来像这样吗？

GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4, 5.6.7.8' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

或者这是不允许的？

Answer 1

您可以多次运行上述命令以从多个IP进行GRANT访问。

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'5.6.7.8' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

到所有ips

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

Answer 2

使用MySQL通配符。 而不是使用有限的数字，您可以实现通配符。这可以通过添加＆＃39;％＆＃39;来完成。而不是数字。
