红帽全球峰会第 2 章 Using MySQL
MySQL server is a high-performance, open source relational database management system (RDBMS). It offers an SQL interface for data access and includes advanced features, such as support for multiple storage engines.
Learn how to install and configure MySQL on a RHEL system, how to back up MySQL data, how to migrate from an earlier MySQL version, and how to replicate a MySQL database.
2.1. Installing MySQL
RHEL 10 provides MySQL 8.4 as the initial version of the Application Stream, which can install as an RPM package. Additional MySQL versions are provided as modules with a shorter life cycle in minor releases of RHEL 10.
By design, you can install only one version (stream) of the same module and, because of conflicting RPM packages, you cannot install MariaDB and MySQL on the same host. As an alternative, you can run the database server services in a container. See Using containers to run multiple MariaDB and MySQL instances on a single host.
Procedure
Install MySQL server packages:
# dnf install mysql8.4-serverEnable and start the
mysqldservice:# systemctl enable --now mysqld.serviceImprove the security after the installation:
$ mysql_secure_installationThe command launches a fully interactive script, which prompts for each step in the process. The script enables you to improve security in the following ways:
- Setting a password for root accounts
- Removing anonymous users
- Disallowing remote root logins (outside the local host)
