MySQL从流读取失败 [英] MySQL Reading from stream failed

问题描述

我间歇性地遇到以下错误.通过在mysql服务器设置中使用跳过名称解析"选项可以解决该问题.

I am facing the following error intermittently. It is solved by using 'skip name resolve' option in the mysql server settings.

但是，根据网上发现的许多建议，使用127.0.0.1应该可以解决此问题.但这也无济于事，您能否建议我一种解决方法或一条SQL命令，通过它我可以检查跳过名称解析"选项.

However, as per many suggestions found on net, using 127.0.0.1 should have solved the issue. But this too didn't help can you suggest me a workaround or a SQL command through which I can check the 'skip name resolve' option.

Error 1: 0
Authentication to host '127.0.0.1' for user 'root' using method 'mysql_native_password' failed with message: Reading from the stream has failed.

推荐答案

这是在更新到MySQL Server 8. +时发生的常见错误. 默认情况下，MySQL 8使用caching_sha2_password，它是mysql_native_password之上的升级身份验证插件.

This is a common error that happens when you update to MySQL Server 8.+. By default MySQL 8 uses caching_sha2_password which is an upgraded authentication plugin over the mysql_native_password.

解决此问题的一种方法是将用户密码的插件专门设置为caching_sha2_password

A way to fix this is by either specifically setting the plugin for the user's password to caching_sha2_password

CREATE USER 'sha2user'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'password'

更新MySQL服务器以接受mysql_native_passwords.

Updating the MySQL Server to accept mysql_native_passwords.

[mysqld]
default_authentication_plugin=mysql_native_password
