所以我有一台新电脑，我正在尝试为一些项目设置一切。
当我尝试导入某些数据库时，在 phpmyadmin 中导入失败后收到此消息：
Missing expression. (near "ON" at position 25)
SET FOREIGN_KEY_CHECKS = ON;
MySQL error 2006: mysql server has gone away
我从 phpmyadmin 注销了，尽管导入只需要几秒钟。
我已经阅读了一些提示并且我已经这样做了：
- 设置 my.cnf 值，例如：
[mysql]
max_allowed_packet=512M
[mysqld]
max_allowed_packet=512M
wait_timeout=600
interactive_timeout = 86400
- 并将我的 php.ini 调整为：
max_execution_time = 500
max_input_time = 500
memory_limit = 512M
post_max_size = 512M
upload_max_filesize = 256M
- 尝试通过命令行导入：
mysql -u USER -p database < import.sql
命令行给我这个错误：
ERROR 2013 (HY000) at line 12042: Lost connection to MySQL server during query
显然这不仅仅是一些 php 的东西。
导入好像失败了。我尝试了多个数据库。有些是 10MB，有些是 120MB。如果我启动一个新的 Web 应用程序或 WordPress 实例，一切都会正常工作并且根本没有错误。但失败的数据库也应该可以正常工作。至少在制作、舞台和我以前的工作机器上是这样。
所以我在这里有点迷失了。
以下是当前版本：
Ubuntu 20.04
mysql Ver 8.0.27-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))
PHP 7.4.25 (cli) (built: Oct 22 2021 12:34:33) ( NTS )
phpmyadmin 4:4.9.5+dfsg1-2
Update:我查看了mysql的error.log：

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

也许有人遇到过这个？
