Question

背景

我有一个基本的Laravel应用程序，运行正常。我在上面运行了php artisan make:auth，进行了迁移，注册了新用户并能够登录和查看home.blade.php。我正在使用代客服务服务该网站，并将其停放在目录中。

我不使用Homestead，而只是使用本地计算机。

导致问题的原因

我运行了brew update / brew upgrade，现在根本无法登录到该应用程序。

预期结果

登录到应用程序并查看home.blade.php

引发错误

PDOException (2006) SQLSTATE[HY000] [2006] MySQL server has gone away在浏览器中显示。

PDOException(code: 0): PDO::__construct(): Unexpected server respose while doing caching_sha2 auth: 109显示在Laravel日志中。

我怀疑与MySQL的用户权限有关，尽管我在这里处于停滞状态，所以我认为我应该把它扔给Obi-Wan的计算机世界。

有效的方法

我仍然可以在浏览器中查看welcome.blade.php，并且对服务器执行ping操作会返回响应，这样就可以了。

我可以通过终端以root身份登录MySQL没问题。

mysql -u root -p

mysql> SELECT user, host FROM mysql.user;
+------------------+-----------+

| mysql.sys        | localhost |
| root             | localhost |

我的数据库存在

我一直在尝试什么：

mysql> GRANT ALL PRIVILEGES ON digitalchef.* TO 'root'@'localhost'; 但没有骰子。
我已经重新启动了nginx，php，mysql。
我看了这个答案：Set modes in the database.php
并尝试执行以下步骤：Create a new user and grant privileges
我一直在这里PHP Bug 76651上读书，看来这是一个问题使用PHP 7.2.8。

我不想不必回滚到7.2.7，但是如果这是唯一的选择，那么我想我正处于困境和困境之间，别无选择。

任何帮助都会很棒。如果您需要有关任何内容的更多信息，请问一下，我会回答。提前非常感谢您！

Answer 1

这对我有用。我使用以下命令使用新的身份验证插件更新密码。您现在可以使用MySQL 8。玩得开心。

ALTER USER `username`@`localhost` IDENTIFIED WITH caching_sha2_password BY 'password';

如果上述方法不起作用，请改用此方法。

ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Answer 2

安装mysql和卸载mysql / maria db无法解决该问题。发生这种情况可能有多种原因。

这通常表示MySQL服务器连接问题或超时。

您可以通过调整my.cnf和wait_timeout来调整max_allowed_packet中的设置。

尝试将其设置为更高的值，继续调整设置，直到正确为止。进行这些更改后，请确保重新启动mysql。

wait_timeout = 28800

max_allowed_packet = 8M

以下是您需要更改的很好的说明

解决了这个问题！哇！再次感谢大家提供的所有建议，我非常感谢您的帮助。

我如何解决：

深入研究这个问题，我发现我安装了2个MySQL版本-5.7和8.0。

我通过自制软件卸载了mysql@5.7
- brew uninstall mysql@5.7
链接了正确的版本
- brew link mysql@8.0
我更新了我的$ PATH
- sudo nano ~/.bash_profile
- 并在5.7处添加了以下行：
- export PATH="/usr/local/opt/mysql@8.0/bin:$PATH"
我遵循@poohbear 's answer here来更改mysql用户
然后，我从mysql提示符处截断了Laravel数据库上的用户表
- mysql -u root -p
- mysql> USE digitalchef;
- mysql> TRUNCATE TABLE users;

我不知道事后是否完成了任何事情，但是我确保在事后运行php artisan config:cache，只是为了很好。

希望这可以帮助正在为此苦苦挣扎的人！再次感谢大家的支持，@ poohbear的回答值得为之疯狂。

如果msyql客户端正常，则只有php7脚本有问题，您可以检查php.ini（mysqlnd.net_read_timeout）

Answer 5

您可能已经重新启动了mysql，但如果没有，请尝试执行

万一它不起作用，请尝试将其卸载：

brew uninstall mysql

并安装mariadb，它将类似于mysql：

brew install mariadb

然后，您仍然可以mysql -uroot来管理数据库

Laravel 5.6 MySQL Server已经消失
