Xampp/ Lampp Mysql 終端訪問錯誤 1045 (28000)

Question

安裝在 Ubuntu 16.04 LTE Xampp (lampp) 一切正常它有效：

# ~ $ Sudo / opt / lampp / lampp status
Version: XAMPP for Linux 5.6.20-0
Apache is running.
MySQL is running.
ProFTPD is running.

但是我要輸入的時候，TERMINAL有mysql：

#:~$ mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
#~$ sudo mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
#~$ sudo mysql -u root -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

我沒有定義密碼，我輸入的密碼是：password

你能幫助我嗎？

Answer 1

嘗試： mysql -u root -p

會在下一行詢問密碼

Answer 2

我這樣做：

sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
mysql -uroot
use mysql;

mysql> select * from user \G

4 rows in set (0,00 sec)

如果我想這樣做：

mysql> update user set password=PASSWORD("newpw") where User='root';
ERROR 1054 (42S22): Unknown column 'password' in 'field list'
mysql> flush privileges;
Query OK, 0 rows affected (0,00 sec)

我在論壇上找到的說明：

sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
mysql -uroot
use mysql;
update user set password=PASSWORD("newpw") where User='root';
flush privileges;
quit
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

或者我可以例如完全刪除mysql，然后重新安裝終端？ 然后升級我的database.sql

Answer 3

默認的root密碼是空白（即空），而不是root。 因此，您可以僅以以下身份登錄：

mysql -u root

您顯然應該在安裝后更改root密碼

mysqladmin -u root password [newpassword]

Answer 4

我的 MySQL 也有同樣的啟動問題，它不讓我登錄。 所以我用了：

mysqladmin.exe -u root password <newpassword>

比它奏效。 所以我去了文件 config.inc,php 並更改為我剛剛設置的新密碼。 並重新啟動我的 xampp 面板：所以我使用了命令：

mysql -u root -p

並輸入我的新密碼並成功！
