全新安裝 mysql-server 後,無法使用 mysql root -u

編輯:我相信這實際上是https://askubuntu.com/questions/766334/cant-login-as-mysql-user-root-from-normal-user-account-in-ubuntu-16-04我 的副本使用了該頁面的最佳答案,並且有效。
我剛剛安裝了一個新的 Linux Mint 18 MATE,並且正在嘗試安裝 Mysql。我這樣做如下:
sudo apt-get install mysql-server
已安裝
mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrappe
這經歷了一些提示我輸入密碼的“gui”螢幕。我只是為每個輸入,我認為這就像在說“沒有密碼”。
但現在,我想我可以用 進入它
mysql -u root
,但它說ERROR 1698 (28000): Access denied for user 'root'@'localhost'
我嘗試重新啟動以防萬一。問題是我沒有使用正確的密碼,還是更根本的問題?如果是密碼,我如何找出它是什麼/重置它?謝謝,馬克斯
編輯:在下面f35的回答之後,我做了以下事情:
sudo service mysql stop sudo mysqld_safe --skip-grant-tables & mysql -u root
然後在 mysql 中,我嘗試更改密碼,但它無法辨識欄位名稱:我做了一個 desc 以查看其中的內容:

不知道下一步該做什麼 - 另外,設置無密碼的語法是什麼?只是
set password=''
嗎?注意:我也可以使用 debian-sys-main 使用者登錄,但仍然不確定如何更改 root 使用者的密碼。
我的mysql版本是:伺服器版本:5.7.16-0ubuntu0.16.04.1(Ubuntu)
1)您可以嘗試重新配置 mysql-server :
sudo dpkg-reconfigure mysql-server
- 檢查你是否有 debian-sys-maint passwd
cat /etc/mysql/debian.cnf
並檢查:
user = debian-sys-maint password = xxxxGx0fSQxxGa
debian-sys-maint 擁有 mysql 伺服器的所有權限
3)如果不能解決問題,你可以重置密碼:
sudo service mysql stop sudo mysqld_safe --skip-grant-tables & mysql -u root mysql> use mysql; mysql> update user set password=PASSWORD("NewPasswd") where User='root'; mysql> flush privileges; mysql> quit sudo service mysql stop sudo service mysql start mysql -u root -p
