1.数据库配置
(1).yum安装mysql
[root@myslserver ~]# yum -y install mysql mysql-server
(2).启动数据库，设置开机启动
[root@myslserver ~]# service mysqld start
[root@myslserver ~]# chkconfig mysqld on
(3).设置数据库密码
[root@myslserver ~]# mysqladmin -uroot password 'passwd'
(4).创建keystone、glance、nova、glance数据库
[root@myslserver ~]# mysql -u root -ppasswd
mysql> create database keystone;
mysql> grant all on keystone.* to 'keystone'@'%' identified by 'keystone';
mysql> create database glance;
mysql> grant all on glance.* to 'glance'@'%' identified by 'glance';
mysql> create database nova;
mysql> grant all on nova.* to 'nova'@'%' identified by 'nova';
mysql> create database cinder;
mysql> grant all on cinder.* to 'cinder'@'%' identified by 'cinder';
mysql> flush privileges;
mysql> quit;
2.控制节点配置
以下为Controller配置，两个节点配置基本相同，在此以controller01配置举例：
配置说明：
黑色：表示controller01,02相同配置。
蓝色：表示controller01的配置。
绿色：表示controller02的配置。
橙色：只在一个节点上执行即可。
2.1.初始化配置
(1).设置hosts文件
[root@controller01 ~]# vi /etc/hosts
192.168.20.20 controller
192.168.20.21 controller01
192.168.20.22 controller02
192.168.20.25 mysqlserver
(2).设置dns解析，便于yum更新
[root@controller01 ~]# vi /etc/resolv.conf
nameserver 202.106.0.20
nameserver 202.96.69.38
nameserver 8.8.8.8
(3).yum管理工具
[root@controller01 ~]# yum -y install wget parted ntpdate
(4).磁盘分区，用于gluster存储
[root@controller01 ~]# parted /dev/vda
