安装 Percona XtraDB 集群 FOR CentOS
简介
Percona Server 是 MySQL 的衍生版，专注于 Linux/BSD 下 MySQL 数据库服务器的改进，
在功能和性能上较 MySQL 有着显著的提升。Percona Server 的使用和 MySQL 完全一致，你
完全可以把它当成是 MySQL 来使用。
Prerequisites
This tutorial will show how to install the Percona XtraDB Cluster on three CentOS
7.0 servers (CentOS 7.0 x86_64), using the packages from Percona repositories.
This cluster will be assembled of three servers/nodes:
node #1
hostname: demo001
IP: 9.110.187.80
node #2
hostname: demo002
IP: 9.110.187.81
node #3
hostname: demo003
IP: 9.110.187.82
All three nodes have a CentOS 7.0 installation.
Firewall has been set up to allow connecting to ports 3306, 4444,
4567 and 4568
SELinux is disabled
in order for Percona XtraDB Cluster to work correctly firewall has to be set up
to allow connections on the following ports: 3306, 4444, 4567 and
4568. Percona XtraDB Cluster currently doesn’t work
with SELinux or apparmor so they should be disabled, otherwise individual
nodes won’t be able to communicate and form the cluster.
