mysql安裝過程中出現錯誤ERROR 1820 (HY000): You must SET PASSWORD before executing this statement解決 最近新裝好的mysql在進入mysql工具時，總是有錯誤提示: # mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) 或者 # mysql -u root -p password 'newpassword' Enter password: mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: YES)' 現在終於找到解決方法了。本來准備重裝的，現在不必了。 方法操作很簡單，如下： # /etc/init.d/mysql stop # mysqld_safe --user=mysql --skip-grant-tables --skip-networking & # mysql -u root mysql mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root' and host='root' or host='localhost';//把空的用戶密碼都修改成非空的密碼就行了。 mysql> FLUSH PRIVILEGES; mysql> quit # /etc/init.d/mysqld restart # mysql -uroot -p Enter password: <輸入新設的密碼newpassword> MySql5.6操作時報錯：You must SET PASSWORD before executing this statement解決 mysql> SET PASSWORD = PASSWORD('123456'); Query OK, 0 rows affected (0.03 sec) mysql> create database roger; Query OK, 1 row affected (0.00 sec) 也就是用mysql> SET PASSWORD = PASSWORD('123456');這句話重新設置一次密碼！
