【中文标题】phpmyadmin：无法登录

【英文标题】：phpmyadmin: Can't login

【发布时间】：2018-02-10 14:49:24

【问题描述】：

我在Linode 服务器中安装了phpmyadmin。

我设置了mysql 密码，但是当我尝试通过 phpmyadmin 界面登录时，我收到消息：

 #1045 - Access denied for user 'root'@'localhost' (using password: YES)

我也通过终端尝试过： mysql -u 根目录 -p 根

然后我收到以下消息：

#1045 - Access denied for user 'root'@'localhost' (using password: YES)

我的config.inc.php 文件是：

<?php
/**
 * Debian local configuration file
 *
 * This file overrides the settings made by phpMyAdmin interactive setup
 * utility.
 *
 * For example configuration see
 *   /usr/share/doc/phpmyadmin/examples/config.sample.inc.php
 * or
 *   /usr/share/doc/phpmyadmin/examples/config.manyhosts.inc.php
 *
 * NOTE: do not add security sensitive data to this file (like passwords)
 * unless you really know what you're doing. If you do, any user that can
 * run PHP or CGI on your webserver will be able to read them. If you still
 * want to do this, make sure to properly secure the access to this file
 * (also on the filesystem level).

【问题讨论】：

@YanetPedraza 我试过了，但还是没有成功。

@YanetPedraza 是的，我编辑了我的问题。

如果使用 $cfg['Servers'][$i]['AllowNoPassword'] = false; 修改文件怎么办？并重启服务器

@YanetPedraza 不，错误仍然存​​在。

为什么不在配置文件中创建：$cfg['Servers'][$i]['user'] = 'username'; $cfg['Servers'][$i]['password'] = 'password';

【参考方案1】：

注意在某些情况下可能需要转义的特殊字符。

使用命令行工具时，-p后面不要有空格：

$ mysql -u root -proot
                  ^

如果您没有正确的 root 密码，请阅读有关如何使用--skip-grant-tables 无需密码即可进入的文档。

【讨论】：

不幸的是，问题仍然存在。我可以在不登录mysql的情况下创建一个新用户到mysql吗？

就是这样！谢谢！您可以在这里找到解决方案：support.rackspace.com/how-to/…。如果 '/var/run/mysqld' for UNIX socket file don't exists. 只需写 mkdir -p /var/run/mysqld 和下一个 'chown mysql:mysql /var/run/mysqld. In case you get Unknown column 'password' in 'field list'` 去这里：***.com/questions/30692812/… .
