HomeDatabaseMysql Tutorialubuntu下root用户名进不去mysql,如何查看用户名和密码,如何修_MySQL

Ubuntu

mysql -u root -p 按回车,输入密码后提示access denied......ues password YES/NO的错误。

第一步:

这时你需要进入/etc/mysql目录下,然后sudo vim/vi debian.cnf查看里面的用户名和密码,然后使用这个文件中的用户名和密码进入mysql,假如debian.cnf中的用户名为debian-sys-maint,则:

mysql -u debian-sys-maint -p按回车,这时需要你输入密码,复制debian.cnf中的密码(不要手动输入,因为容易产生错误)。

此时你能进入到mysql里面了。


第二步:

修改人root密码

根据上一步登录mysql客户端
mysql> use mysql;
Database changed
mysql> update user set password=password('new password') where user='root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4  Changed: 4  Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> quit


第三步:

用新改的root和密码登录查看。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3.
