1.数据库配置
(1).yum安装mysql
# yum -y install mysql mysql-server
(2).启动数据库，设置开机启动
# service mysqld start
# chkconfig mysqld on
(3).设置数据库密码
# mysqladmin -uroot password 'passwd'
(4).创建keystone、glance、nova、glance数据库
# 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
# 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
# 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
# yum -y install wget parted ntpdate
(4).磁盘分区，用于gluster存储
# parted /dev/vda
GNU Parted 2.1
使用 /dev/vda

2.2.安装配置Gluster
(1).设置gluster源
# wget -P /etc/yum.repos.d http://download.gluster.org/pub/gluster/glusterfs/LATEST/CentOS/glusterfs-epel.repo
(2).yum安装gluster
# yum -y install glusterfs-server glusterfs
(3).启动gluster服务，设置开机启动
# service glusterd start
# chkconfig glusterd on
(4).添加存储节点
# gluster peer probe controller02
# gluster peer probe controller01
(5).查看节点状态
# gluster peer status
(6).创建volume并启动
# gluster volume create vol-storage replica 2 controller01:/data/gluster controller02:/data/gluster
# gluster volume start vol-storage
(7).关闭gluster的nfs属性
# gluster volume set vol-storage nfs.disable on
(8).挂载volume
# mkdir -p /openstack
# mount -t glusterfs controller01:/vol-storage /openstack
# echo "controller01:/vol-storage /openstack glusterfs defaults,_netdev 0 0" >> /etc/fstab
# mount -t glusterfs controller02:/vol-storage /openstack
# echo "controller02:/vol-storage /openstack glusterfs defaults,_netdev 0 0" >> /etc/fstab
2.3.安装配置haproxy,keepalived
(1).修改sysctl.conf配置文件
# vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.ip_nonlocal_bind = 1
net.ipv4.conf.all.rp_filter = 0
net.ipv4.conf.default.rp_filter = 0
# sysctl -p
(2).yum安装haproxy,keepalived
# yum -y install keepalived haproxy
(3).配置keepalived
# cp -av /etc/keepalived/keepalived.conf/etc/keepalived/keepalived.conf_bak
# echo "" > /etc/keepalived/keepalived.conf
# vi /etc/keepalived/keepalived.conf
