四、安装依赖包
1、安装包准备
安装光盘package目录下：perl-DBD-MySQL-4.013-3.el6.x86_64.rpm
注：在Redhat Linux下，还需要安装Mysql客户端
wget http://repo.webtatic.com/yum/el6/x86_64/libmysqlclient16-5.1.69-1.w6.x86_64.rpm
wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/socat-1.7.2.4-1.el6.rf.x86_64.rpm
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/nc-1.84-22.el6.x86_64.rpm 2、安装
rpm -ivh perl-DBD-MySQL-4.013-3.el6.x86_64.rpm socat-1.7.2.4-1.el6.rf.x86_64.rpmnc-1.84-22.el6.x86_64.rpm libmysqlclient16-5.1.69-1.w6.x86_64.rpm

五、删除原有软件包
rpm -qa | grepmysql | xargs sudo rpm -e --nodeps
六、安装

rpm -ivhpercona-xtrabackup-2.1.9-744.rhel6.x86_64.rpm
2、安装Percona-XtraDB-Cluster-galera
rpm -ivhPercona-XtraDB-Cluster-galera-3-3.5-1.216.rhel6.x86_64.rpmPercona-XtraDB-Cluster-galera-3-debuginfo-3.5-1.216.rhel6.x86_64.rpm
3、安装Percona-XtraDB-Cluster-client
rpm -ivhPercona-XtraDB-Cluster-client-56-5.6.15-25.5.759.rhel6.x86_64.rpm
4、安装Percona-XtraDB-Cluster-server
rpm -ivhPercona-XtraDB-Cluster-server-56-5.6.15-25.5.759.rhel6.x86_64.rpm

七、修改配置文件

find / -name 'my-default.cnf'
cp my-default.cnf /etc/my.cnf

八、Cluster配置
在配置文件中增加如下部分：(/etc/my.cnf)

Percona XtraDB Cluster Documentation, Release 5.6.15-25.5
[mysqld]
datadir=/var/lib/mysql
user=mysql
# Path to Galera library
wsrep_provider=/usr/lib64/libgalera_smm.so
# Cluster connection URL contains the IPs of node#1,node#2 and node#3
wsrep_cluster_address=gcomm://192.168.70.71,192.168.70.72,192.168.70.73
# In order for Galera to work correctly binlog formatshould be ROW
binlog_format=ROW
# MyISAM storage engine has only experimental support
default_storage_engine=InnoDB
# This changes how InnoDB autoincrement locks are managedand is a requirement for Galera
innodb_autoinc_lock_mode=2
# Node #1 address
wsrep_node_address=192.168.70.71 # 本机IP地址
# SST method
wsrep_sst_method=xtrabackup-v2
# Cluster name
wsrep_cluster_name=my_centos_cluster
# Authentication for SST method
wsrep_sst_auth="sstuser:s3cret"

注：其他节点配置文件同上，注意wsrep_node_address=192.168.70.71 # 本机IP地址。

在第一个节点上执行：
mysql@percona1> CREATE USER 'sstuser@'localhost'IDENTIFIED BY 's3cret';
mysql@percona1> GRANT RELOAD, LOCK TABLES, REPLICATIONCLIENT ON
*.* TO 'sstuser'@'localhost';
mysql@percona1> FLUSH PRIVILEGES;

九、启动
第一个节点：/etc/init.d/mysql bootstrap-pxc
其他节点： /etc/init.d/mysqlstart

十、更改root口令并授权从任何主机访问
登录mysql:
Mysql -u root –p
Mysql>
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY'mysql' WITH GRANT OPTION;
