A MySQL installation
sudo apt-get update
sudo apt-get install mysql-server
Two password problem
When prompted to set a password to install 1
This situation no problem, log on MySQL by order has been given
mysql -u root -p
No password when prompted to install 2
This situation can try to use an empty password to log in
3 no password prompt and a blank password can not log installation
I encountered no password prompt and empty password is invalid when you install MySQL, the following error message:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
Three solutions (can also be used to forget the root password)
Ubuntu creates one for users when installing MySQL Debian-SYS-main t we can be set by the user this user
1 View debian-sys-maint password
sudo cat /etc/mysql/debian.cnf
2 Log debian-sys-maint user
mysql -u debian-sys-maint -p
Note: At this point just found the password for the password
Now we have to log in to the MySQL
3 Set the root password
use mysql;
update mysql.user set authentication_string=password('你的密码') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password";
flush privileges;
quit;
OK! Problem solved
