MySQL 5.7.11 mysql_secure_installation 不工作

Question

Linux 版本:Ubuntu 14.04.1 LTS服务器版本:5.7.11 MySQL Community Server (GPL)从以下链接下载: http://dev.mysql.com/downloads/repo/apt/

当我尝试运行 mysql_secure_installation我设置密码并重新加载所有已完成的任务。但是当我尝试登录 mysql 时，它不需要 root 用户的密码。

>>>mysql 


mysql> select * from user;

不需要任何密码？

不知道为什么？

Answer 1

我认为问题出在plugin列的mysql.user，变量名是auth_socket。

https://dev.mysql.com/doc/refman/5.7/en/pluggable-authentication.html https://dev.mysql.com/doc/mysql-security-excerpt/5.5/en/socket-authentication-plugin.html

如果要更改mysql用户的身份验证，请按照以下步骤操作:

ALTER USER 'root'@'localhost' IDENTIFIED with mysql_native_password;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

这应该有效。
