MySQL is a widely used relational database management system. This article will introduce how to install MySQL through rpm on CentOS system.

Select the appropriate version of the MySQL software package to download from the MySQL official website. Here, MySQL Community Server 8.0.25 is taken as an example. The download address is https://dev.mysql.com/downloads/mysql/.

According to the number of bits configured in the system (32-bit or 64-bit), select the corresponding compressed package to download. Here we choose the rpm package of CentOS 7 64-bit version.

After execution, you will be asked to enter the initial password. If this is the first installation, the MySQL administrator account does not have a password, just press Enter.

You will then need to enter a new password. Require strong passwords and avoid simple passwords. Please follow the prompts and set a password of at least 8 characters.

Next, you need to answer some security questions:

• Do you want to prohibit root remote login? Enter y for forbidden.
• Delete the test database? Enter y for delete.

After setting up, restart the MySQL service to make the changes take effect:
