ROOT is a superuser account in UNIX systems, such as AIX, BSD, and UNIX-like systems like Linux (including Debian, Red Hat, Ubuntu, and Arch Linux). In Linux distributions and the Android system, it's the only superuser, similar to the SYSTEM user in older Windows versions or TrustedInstaller in Vista and later. This user has full control over the system, allowing actions like starting or stopping processes, adding or removing users, and managing hardware.
As the sole administrator, the root user holds complete authority over the system. Some applications require root access, such as ad-blocking tools. However, due to its power, improper use of root can lead to severe damage, potentially rendering the system unusable. Therefore, it's generally not recommended to use the root account unless absolutely necessary. Instead, it's safer to create a regular user for daily tasks.
MySQL is a relational database management system (RDBMS) developed by MySQL AB in Sweden and now owned by Oracle. It's one of the most popular RDBMS solutions, especially for web applications. MySQL organizes data into multiple tables rather than storing everything in a single repository, which improves performance and flexibility.
The SQL language used by MySQL is standardized and widely adopted for database access. MySQL offers both a community and a commercial version. Its small size, speed, and open-source nature make it a popular choice for small and medium-sized websites.
**Changing the Root Password in MySQL**
There are several methods to change the root password in MySQL, depending on your situation:
**Method 1: Use the SET PASSWORD Command**
Log in to MySQL using `mysql -u root` and then run:
`SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');`
**Method 2: Use mysqladmin**
If you know the current password:
`mysqladmin -u root password 'newpass'`
If you need to change an existing password:
`mysqladmin -u root -p oldpass password 'newpass'`
**Method 3: Edit the User Table Directly with UPDATE**
Log in to MySQL and execute:
`use mysql;`
`UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';`
`FLUSH PRIVILEGES;`
**Method 4: Reset Password When Forgotten**
Stop the MySQL service, start it with `--skip-grant-tables`, log in without a password, and update the password:
`UPDATE user SET password=PASSWORD('newpass') WHERE user='root';`
Then run `FLUSH PRIVILEGES;` and restart the service.
**How to Modify the MySQL Root Password on Windows**
MySQL is a powerful RDBMS often used with PHP and Apache for web development. Many users may need to change their root password due to forgotten passwords or weak security. Here are the steps for Windows:
**Tools Required:**
- Windows OS
- MySQL installed
**Method 1: Using the SET PASSWORD Command**
Open the command prompt (`Win + R` > `cmd`) and run:
`mysql -u root -p`
Then enter:
`SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpassword');`
**Method 2: Using mysqladmin**
Run:
`mysqladmin -uroot -p oldpassword password newpassword`
**Method 3: Updating the User Table**
Log in to MySQL, switch to the `mysql` database, and run:
`UPDATE user SET password = PASSWORD('newpass') WHERE user = 'root';`
Then:
`FLUSH PRIVILEGES;`
**Method 4: Resetting the Password if Forgotten**
Stop the MySQL service, start it with `--skip-grant-tables`, log in, and update the password:
`UPDATE user SET password = PASSWORD('newpass') WHERE user = 'root';`
Then:
`FLUSH PRIVILEGES;`
Always remember to restart the MySQL service after making changes. If commands don’t work, ensure that the MySQL bin directory is added to your system’s PATH variable.
