之前MySQL服务端本机上使用密码登陆root账号是没有问题的,但是今天不知道是因为动了哪里,登陆失败并有这个错误代码:
~$ mysql -u root -p Enter password: ERROR 1698 (28000): Access denied for user ‘root‘@‘localhost‘
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 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 | +-----------+-----------------------+ 3 rows in set (0.01 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, 1 row affected, 1 warning (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 1 mysql> flush privileges; Query OK, 0 rows affected (0.00 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 -p Enter password: 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)
