mysql - 我把phpmyadmin的mysql端口号改了，现在登不上了

Question

我有一个本地运行在 3307 端口的 mysql 服务器，我可以通过命令行连接到它

mysql -P 3307 -h 127.0.0.1 -u root -p

为了通过 phpmyadmin 访问这个数据库，我在/etc/phpMyAdmin/config.inc.php 中更改了这些设置

$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['port'] = '3307'; 

但是，当我尝试登录时，出现“无法登录到 mysql 服务器”的错误消息。这可能是 apache 阻止登录的问题吗？

我尝试使用 localhost/phpMyAdmin 和 127.0.0.1/phpMyAdmin 进行连接。

下面是我的config.inc.php文件

转到 xampp>phpMyAdmin 目录。

找到 config.inc.php 文件。

现在改变这一行:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

到

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

或

打开XAMPP/mysql/bin/目录下的my.ini文件，找到包含数字3306的单词，eq:port=3306，然后替换成你自己的，比如3307。
