一,问题描述:
MysqlERROR1698(28000)解决,新装了mysql-server-5.7,登录为这一问题,普通用户不能进mysql,只有root用户才能进,并且不需要任何密码。

~$ mysql -u root -p Enter password : ERROR 1698 (28000): Access denied for user 'root' @ 'localhost' |
二,解决步骤:
停止mysql服务
1
|
~$ sudo service mysql stop |
以安全模式启动MySQL
1
|
~$ sudo mysqld_safe --skip-grant-tables & |
MySQL启动之后就可以不用密码登陆了

~$ mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.10 MySQL Community Server (GPL) |
查看一下user表,错误的起因就是在这里, root的plugin被修改成了auth_socket,用密码登陆的plugin应该是mysql_native_password。

mysql> select user , plugin from mysql. user ; + -----------+-----------------------+ | user | plugin | + -----------+-----------------------+ | root | auth_socket | | mysql.sys | mysql_native_password | | dev | mysql_native_password | + -----------+-----------------------+ <strong>3</strong> rows in set (<strong>0.01</strong> sec) |
关于auth_socket,在官方有说明: https://dev.mysql.com/doc/mysql-security-excerpt/5.5/en/socket-authentication-plugin.html ,反正现在暂时不用它, 那就把这里改了。
