1. Machine information
2. Preparation
2.1 , close the NetworkManager service
2.2 , upload the repo file
2.3 . Do time synchronization on each machine
2.4 、Close the selinux service and configure the firewall on each machine
2.5 , configure the hosts file on each machine
3. Deploy O+G environment
3.1 、Install gfs components on each machine
3.2 . Install packstack on YUN 21 and deploy openstack
3.3 , create a gfs volume and mount it
3.4 , enter dash , upload image, create network, modify quota
3.5 . Create glance and cinder volumes and mount them
4. System optimization
1. Machine information
hostname NIC inet addr
YUN 21 eth1 10.0.0.21
eth2 192.168.0.121

Installed the desktop version of the centos6.5 system
(The reason for installing the desktop version of the system is that the identification of hardware by different physical machines requires differences in software package support. For example, in one case, after installing a system with a desktop on a Lenovo physical machine, it does not need to install additional drivers. The intel 10 Gigabit network card on the physical machine , which does not exist on the system without the desktop).
2. Preparation
2.1. Close the NetworkManager service
如果不关闭的话，都无法PING通其他机器，在最简版的centos系统中不需要考虑这个服务。
每个机器上都做下面操作
# service NetworkManager stop
# chkconfig NetworkManager off
2.2、上传repo文件
每个机器上操作
# yum makecache
2.3、在每个机器上做时间同步
# yum install -y ntp ntpdate ntp-doc
配置NTP
# vi /etc/ntp.conf
把下面的内容加以注释，使其失效
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
restrict 127.0.0.1
restrict -6 ::1
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
添加一行
server 192.168.0.100
# service ntpd start
# chkconfig ntpd on
# ntpdate -u 192.168.0.124
（IP地址是192.168.0.124的物理机是配置好的NTP服务器端）
2.4、每台机器上关闭selinux服务、配置防火墙
# setenforce 0
# vi /etc/sysconfig/selinux
SELINUX=disabled
# vi /etc/sysconfig/iptables
在ssh规则下添加
-A INPUT -p tcp -m multiport --dports 24007:24047 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 111 -j ACCEPT
-A INPUT -p udp -m udp --dport 111 -j ACCEPT
-A INPUT -p tcp -m multiport --dports 38465:38485 -j ACCEPT
-A INPUT -p tcp -m multiport --dports 49152:49216 -j ACCEPT
-A INPUT -p tcp -m multiport --dports 16509 -j ACCEPT
# service iptables restart
2.5、每台机器上配置hosts文件
# vi /etc/hosts
添加
192.168.0.121 YUN21
192.168.0.122 YUN22
192.168.0.123 YUN23
192.168.0.124 YUN24
