你可以查看mysql根密码，好吧，我已经在mysql 5.5上尝试过了，所以不知道其他新版本是否工作良好

nano ~/.my.cnf

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>

去phpMyAdmin > config.inc.php > $cfg['Servers'][$i]['password'] = ";

你找不到它。它存储在一个数据库中，您需要根密码才能访问该数据库，即使您以某种方式获得了访问权限，它也会使用单向散列进行散列。您可以重置:如何重置Root用户密码

在你的“主机名”中。在MySQL工作的数据文件夹中的err文件中，尝试寻找以以下开头的字符串:

“为roor@localhost生成临时密码”

你可以使用

less /mysql/data/dir/hostname.err 

然后使用斜杠命令，后面跟着要查找的字符串

/"A temporary password"

然后按n，进入下一个结果。

mysql服务器安装后的默认密码是:mysql
