Install on Red Hat 8

RHEL 8 and other EL8 systems enable the MySQL module by default. This module hides the Percona-provided packages and the module must be disabled to make these packages visible. The following command disables the module:

sudo yum module disable mysql

sudo yum install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
sudo percona-release setup pxc-84-lts
sudo yum install percona-xtradb-cluster

After installation

After the installation, start the mysql service and use the grep command to find the temporary password.

sudo service mysql start
sudo grep 'temporary password' /var/log/mysqld.log

Use the temporary password to log into the server:

mysql -u root -p

Run an ALTER USER statement to change the temporary password, exit the client, and stop the service.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'rootPass';
exit
sudo service mysql stop

Install on Red Hat 9 or later

RHEL 9 and subsequent versions use the dnf package manager and its module system. The default mysql module must be disabled to prevent conflicts with Percona’s packages.

sudo dnf module disable mysql

Next, install the Percona repository and the cluster.

sudo dnf install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
sudo percona-release setup pxc-84-lts
sudo dnf install percona-xtradb-cluster

After installation

After installation, start the mysqld service and locate the temporary password.

sudo systemctl start mysqld
sudo grep 'temporary password' /var/log/mysqld.log

Use the temporary password to log in, and then run an ALTER USER statement to change it.

mysql -u root -p

Enter the temporary password.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'rootPass';

For security, exit the client and stop the service.

exit

sudo systemctl stop mysqld
