我已经成功安装了 phpmyadmin这里。
在重新启动机器之前，我可以毫无问题地登录。
重新启动机器后，当我要localhost/phpmyadmin输入用户（root）及其密码（123456）时，它让我：
500 Internal Server Error
我不知道那有什么问题！
任何帮助，将不胜感激。

答案1
该错误Internal Server Error可能意味着服务器端存在任何问题。从您的链接判断，您使用 Apache2 作为 Web 服务器。请检查目录中的日志文件/var/log/apache2/，尤其是日志文件/var/log/apache2/error.log以获取更多信息。
根据我的经验，我会说阿帕奇拥有错误的权限PHPMyAdmin文件夹。检查apache user该文件夹是否有读取权限/usr/share/phpmyadmin/。
另请记住，通过运行service apache2 restart或更改其配置后，您需要重新启动 apache web 服务器sudo service apache2 restart。
编辑：
.htpasswd您没有在配置中更改文件的路径，这就是为什么日志文件中出现此错误的原因：
Could not open password file: /path/to/passwords/.htpasswd
仔细阅读您再次使用的指南，并根据您的需要更改路径。
我建议你将该.htpasswd文件移动到与 相同的目录中.htaccess。在终端中输入
sudo mv ~/phpmyadmin_password/.htpasswd /usr/share/phpmyadmin/.htaccess
之后更新您的/usr/share/phpmyadmin/.htaccess文件使其看起来像这样：
AuthType Basic
AuthName "Restricted Files"
AuthUserFile /usr/share/phpmyadmin/.htpasswd
Require valid-user
还要检查两个文件的文件所有权和权限。 apache 用户应该能够读取这两个文件。
