重置mysql的root賬號密碼，置mysqlroot賬號

重置mysql的root賬號密碼，置mysqlroot賬號

先停止mysql服務

/etc/init.d/mysqld stop

以安全模式啟動mysql

/usr/local/mysql/bin/mysqld_safe --skip-grant-tables --skip-networking &

/usr/local/mysql/bin/mysql

UPDATE user SET password=password('12345') WHERE user='root';

flush privileges;

授權

grant all privileges on *.* to root@'localhost' identified by '123456';

flush privileges;

有個地方要注意，/usr/local/mysql/bin/mysqld_safe 方式啟動的時侯默認是讀取/usr/local/mysql/data下的數據，如果你的data數據放在別的目錄就會出現密碼錯誤而被拒絕登陸的錯誤，

可以做個鏈接解決，(實際data目錄的地址/opt/mysql/data) ln -s /opt/mysql/data  /usr/local/mysql/
