php7.4 mysqli与"gone away"超时. [英] php7.4 mysqli times out with "gone away"

问题描述

我刚刚安装了php7.4，看起来一切正常，但是当我尝试使用phpmyadmin时，我无法: 注意在此安装之前在php7.3中工作正常

I have just installed php7.4, everything seems ok but when I try to go on my phpmyadmin, I can't : Note works fine in php7.3 before this installation

错误是:

mysqli_real_connect(): Unexpected server response while doing caching_sha2 auth: 109
 mysqli_real_connect(): (HY000/2006): MySQL server has gone away

寻找我的php mysql库:php7.4-mysql.已安装.

looking my php mysql library :php7.4-mysql. it's installed.

忘记什么? 谢谢.

推荐答案

我也遇到了同样的问题，但是PHP7.4-mysql-pdo不能使用mysql_native_password，即使在my.cnf中进行设置时也无法使用mysql_native_password

I had the same issue, but using mysql_native_password was not possible with PHP7.4-mysql-pdo, even on setting in my.cnf as it worked on PHP7.3-mysql-pdo.

我必须使用以下查询更改每个用户:

I had to alter every user with this query:

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

其中username是数据库用户名，password是数据库用户的密码.

where username is the database username and password is the password of the database user.
