Step 1: Install the Percona repository
We can install Percona yum repository by running the following command.
# yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm Retrieving https://repo.percona.com/yum/percona-release-latest.noarch.rpm Preparing... ########################################### [100%] 1:percona-release ########################################### [100%]

# systemctl start mysql
Next, check the service status by running below command:
# systemctl status mysql
Stop the service by running below command:
# systemctl stop mysql
Restart the service by running by running below command:
# systemctl restart mysql
Once, service is started check the mysql root password by running below command:
# grep 'temporary password' /var/log/mysqld.log
Next reset the password to the one of your choice by logging into the mysql console.
# mysql -u root –p # ALTER USER 'root'@'localhost' IDENTIFIED BY 'StrongPassword'; # flush privileges;
