Note : CentOS 7 prefers MariaDB, a fork of MySQL managed by the original MySQL developers and designed as a replacement for MySQL. MariaDB will generally work seamlessly in place of MySQL.

Check your current Operating System version if you are not sure.

# egrep '^(VERSION|NAME)=' /etc/os-release

For CentOS 7 / Red Hat Enterprise Linux 7 / Oracle Linux 7, first remove MariaDB library, It may create dependency issue:

# yum remove mariadb-libs

 Managing the MySQL service

let’s review some basic management commands.

Verify installed version of MySQL:

#  mysql --version

Start the MySQL service:

# systemctl start mysqld.service

Check status of the MySQL service:

# systemctl status mysqld.service

Restart the MySQL service:

# systemctl restart mysqld.service

If you want to stop MySQL service:

# systemctl stop mysqld.service

By default, MySQL service is disabled to start automatically when the server boots. If you want to enable it at startup, run:

# systemctl enable mysqld.service

Re-disable the service to start up at boot:

# systemctl disable mysqld.service

Uninstall MySQL

To completely remove MySQL from a system, you must remove the MySQL applications, the configuration files, and any directories containing data and logs.

WARNING: This process will completely remove MySQL, its configuration, and all databases. This process is not reversible, so ensure that all of your configuration and data is backed up before proceeding.

Stop the MySQL service

# systemctl stop mysqld.service

Remove any MySQL packages that previously installed.

For RHEL / CentOS/ Oracle Linux / Rocky Linux / Amazon Linux

# yum erase $(rpm -qa | grep mysql*)

Remove MySQL databases and log files.

# rm -rf /var/lib/mysql /var/log/mysql /etc/mysql /var/run/mysqld /etc/apparmor.d/abstractions/mysql
