【中文标题】我更改了phpmyadmin mysql端口号，现在无法登录【英文标题】：I changed the phpmyadmin mysql port number, and now I can't log in 【发布时间】：2019-03-02 12:15:59 【问题描述】：我有一个mysql服务器在3307端口上本地运行，我可以通过命令行很好地连接到它
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，我收到一条错误消息，提示“无法登录到 mysql 服务器”。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

【问题讨论】：
@Martin 如果其他人正在使用它，他会在尝试从 CLI 连接到它时收到错误。 this answer 建议重启 Apache。 this search 显示了许多关于此错误的先前问题，可能其中一个会有所帮助。 您的网络服务器是否在监听本地主机？如果您执行telnet 127.0.0.1 80 并按回车几次，您会收到有关错误请求的 apache 消息，还是无法连接？
@TerryCarmen 几分钟后手动关闭连接时，我收到一条错误的请求消息，“您的浏览器发送了此服务器无法理解的请求”。让它自己运行会导致“连接被外国主机关闭”，仅此而已。这是预期的结果吗？
【参考方案1】：
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
打开位于XAMPP/mysql/bin/目录下的my.ini文件，找到包含数字3306的单词，eq:port = 3306，然后替换成自己的，比如3307。
【讨论】：
不幸的是，这并没有改变任何东西。 @Varma$cfg['Servers'][$i]['port'] = '3307'; 指令不能正常工作有什么原因吗？【参考方案2】：
允许您通过命令提示符登录的用户名/密码将允许您通过 phpmyadmin 登录。
它们需要写在 config.inc.php 文件中：
<?php
/**

* configuration. For easier setup you can use "setup/".

修改后，需要重启web和mysql服务器。
如果这仍然不起作用，您可以再创建一个用户并确保在 config.inc.php 文件中有以下两行：
$cfg['Servers'][$i]['user'] = 'testUser'; //mysql username here
$cfg['Servers'][$i]['password'] = 'testPassword'; //mysql password here
【讨论】：
不幸的是，这并没有改变任何东西 你重启服务器了吗？以上是关于我更改了phpmyadmin mysql端口号，现在无法登录的主要内容，如果未能解决你的问题，请参考以下文章
安装wamp后，如何更改mysql端口号？配置文件以更改且新端口号也启动了，但在加新应用时无法找到mysql连接
如果我在安装过程中更改了 MySQL 的默认端口号（3306），会不会有啥问题？
