MySql Error 1698(28000)問題的解決方法
一,問題描述:
MysqlERROR1698(28000)解決,新裝了mysql-server-5.7,登錄為這一問題,普通用戶不能進mysql,只有root用戶才能進,并且不需要任何密碼。
~$ mysql -u root -p Enter password: ERROR 1698 (28000): Access denied for user 'root'@'localhost'
二,解決步驟:
停止mysql服務
~$ sudo service mysql stop
以安全模式啟動MySQL
~$ sudo mysqld_safe --skip-grant-tables &
MySQL啟動之后就可以不用密碼登陸了
~$ 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,錯誤的起因就是在這里, root的plugin被修改成了auth_socket,用密碼登陸的plugin應該是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)
關(guān)于auth_socket,在官方有說明: https://dev.mysql.com/doc/mysql-security-excerpt/5.5/en/socket-authentication-plugin.html ,反正現(xiàn)在暫時不用它, 那就把這里改了。
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)
重啟服務,問題就解決了
~$ 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)
