Percona provides .rpm packages for 64-bit versions
of Red Hat Enterprise Linux 6 (Santiago) and 7 (Maipo),
including its derivatives that claim full binary compatibility,
for example: CentOS, Oracle Linux, Amazon Linux AMI, and so on.
Note
Percona XtraDB Cluster should work on other RPM-based distributions, but it is tested only on RHEL and CentOS versions 6 and 7.
The packages are available in the official Percona software repository
and on the download page.
It is recommended to intall Percona XtraDB Cluster from the official repository
using yum.
Note
You need to have root access on the node
where you will be installing Percona XtraDB Cluster
(either logged in as a user with root privileges
or be able to run commands with sudo).
Note
Make sure that the following ports are not blocked by firewall or used by other software. Percona XtraDB Cluster requires them for communication.
Note
The SELinux security module
can constrain access to data for Percona XtraDB Cluster.
The best solution is to change the mode
from enforcing to permissive by running the following command:
setenforce 0
This only changes the mode at runtime.
To run SELinux in permissive mode after a reboot,
set SELINUX=permissive in the /etc/selinux/config
configuration file.
Configure Percona repositories as described in Percona Software Repositories Documentation.
Install the Percona XtraDB Cluster packages:
$ sudo yum install Percona-XtraDB-Cluster-57
Note
Alternatively you can install
the Percona-XtraDB-Cluster-full-57 meta package,
which contains the following additional packages:
Percona-XtraDB-Cluster-devel-57Percona-XtraDB-Cluster-test-57Percona-XtraDB-Cluster-debuginfo-57Percona-XtraDB-Cluster-galera-3-debuginfoPercona-XtraDB-Cluster-shared-57Start the Percona XtraDB Cluster server:
$ sudo service mysql start
Copy the automatically generated temporary password for the superuser account:
$ sudo grep 'temporary password' /var/log/mysqld.log
Use this password to log in as root:
$ mysql -u root -p
Change the password for the superuser account and log out. For example:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'rootPass';
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
Stop the mysql service:
$ sudo service mysql stop
After you install Percona XtraDB Cluster and change the superuser account password, configure the node according to the procedure described in Configuring Nodes for Write-Set Replication.
