HomeDatabaseMysql Tutorialxampp默认mysql数据库root密码的修改_MySQL

XAMPP

因为安装xampp后的mysql默认用户root的密码为空,而比如部署Testlink时需要提供数据库密码,此时就需要给root设定密码(网上有些方法,大同小异,但是可能都未标明关键点,未一些出上手的童鞋造成了不成功)。

如下介绍两个方法:

方法一:通过phpmyadmin

xampp也是通过phpmyadmin管理的,所以我们能登录到phpmyadmin,在浏览器地址上输入http://localhost/phpmyamdin 进入到数据库控制面板,然后选择名称为mysql数据库,如图,可从中看出 user表中,root的两个用户的密码为空。

xampp phpmyadmin

我们可以手动编辑上图数据库中的root用户的密码即可。点快速编辑,或者编辑都可以编辑密码,如密码 :123456 ,则填写 “*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9” (引号除外)

注意:不要直接写密码123456.一定要加密的,这也是好多童鞋不成功的原因。

编辑后如下图

当然也可以可以直接执行SQL 语句来修改密码,把new_password改成自己的密码即可:

1

UPDATE user SET password=password('new_password') WHERE user='root';

如:UPDATE user SET password=password('123456') WHERE user='root';

另外既然mysql的root用户密码已经修改了,那么phpmyadmin中的对应密码配置也要修改,找到配置文件,如我的是:
F:/xampp/phpMyAdmin/config.inc.php
找到如下代码

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = '';

$cfg['Servers'][$i]['extension'] = 'mysql';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

修改为

$cfg['Servers'][$i]['auth_type'] = 'config';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = '123456';

$cfg['Servers'][$i]['extension'] = 'mysql';

$cfg['Servers'][$i]['AllowNoPassword'] = true;

当然您不改这块数据库也会照常工作,只不过phpmyadmin是数据库管理程序,我们要用到它来创建管理数据库等操作,如果不修改config.inc.php文件中的内容,则phpmyadmin无法打开页面。

方法二:通过进入bin目录下,进入mysql数据库

如此搞定,exit退出命令行,并重启mysql服务(可以通过xampp pane stop与start),使用mysql -u root -p 尝试密码是否能够登录

How does MySQL handle data replication?How does MySQL handle data replication?Apr 28, 2025 am 12:25 AM

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

How can you use the EXPLAIN statement to analyze query performance?How can you use the EXPLAIN statement to analyze query performance?Apr 28, 2025 am 12:24 AM

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

What is MySQL partitioning?What is MySQL partitioning?Apr 27, 2025 am 12:23 AM

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.
