mysql服务器安装后的默认密码是:mysql

mysql服务器安装后的默认密码是:mysql

MySQL 5.7及以上版本在MySQL日志文件中保存root。

请试试这个:

sudo grep 'temporary password' /var/log/mysqld.log

在Windows系统下，请按照以下步骤重置密码

从任务管理器中停止Mysql服务 创建一个文本文件并粘贴下面的语句

MySQL 5.7.5及以前版本: SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yournewpassword');

MySQL 5.7.6及以上版本: ALTER USER 'root'@'localhost'

保存为mysql-init.txt，并将其放在“C”盘。 打开命令提示符并粘贴以下内容

C:\\ > mysqld——init-file=C:\\mysql-init.txt

系统:

中佐的Linux 7 位于华盛顿市郊1414区

过程:

Open two shell sessions, logging in to one as the Linux root user and the other as a nonroot user with access to the mysql command. In your root session, stop the normal mysqld listener and start a listener which bypasses password authentication (note: this is a significant security risk as anyone with access to the mysql command may access your databases without a password. You may want to close active shell sessions and/or disable shell access before doing this): # systemctl stop mysqld # /usr/sbin/mysqld --skip-grant-tables -u mysql & In your nonroot session, log in to mysql and set the mysql root password: $ mysql mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass'); Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> quit; In your root session, kill the passwordless instance of mysqld and restore the normal mysqld listener to service: # kill %1 # systemctl start mysqld In your nonroot session, test the new root password you configured above: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. ... mysql>

这招对我很管用:

在终端类型上执行如下操作

$ sudo mysql -u root -p

Enter password://直接按Enter
