一,问题描述:
mysql/' target='_blank'>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 -pEnter password: ERROR 1698 (28000): Access denied for user 'root'@'localhost'
二,解决步骤:
停止mysql服务
~$ sudo service mysql stop
以安全模式启动MySQL
~$ sudo mysqld_safe --skip-grant-tables &
MySQL启动之后就可以不用密码登陆了
~$ mysql -u rootWelcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 2Server 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。
mysql> update mysql.user set authentication_string=PASSWORD('newPwd'), plugin='mysql_native_password' where user='root';Query OK, <strong>1</strong> row affected, <strong>1</strong> warning (<strong>0.00</strong> sec)Rows matched: <strong>1</strong> Changed: <strong>1</strong> Warnings: <strong>1</strong>mysql> flush privileges;Query OK, <strong>0</strong> rows affected (<strong>0.00</strong> sec)
重启服务,问题就解决了
~$ sudo service mysql stop... * MySQL Community Server 5.7.10 is stopped~$ sudo service mysql start.. * MySQL Community Server 5.7.10 is started~$ mysql -u root -pEnter password: Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.7.10 MySQL Community Server (GPL)
