centos7 openstack kilo版本一键安装
最近在学习openstack的使用，由于是出于学习的目的使用的是all-in-one方式，在此记录在centos7系统是使用all-in-one方式安装openstack kilo版本的步骤。
centos7系统使用新的接口命名方式，在安装openstack前需要修改接口名称
修改接口名称：
（To restore the old naming convention, you need to edit the /etc/default/grub file and add net.ifnames=0 biosdevname=0 at the end of the GRUB_CMDLINE_LINUX variable:）
/etc/default/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.keymap=us crashkernel=auto rd.lvm.lv=centos/root vconsole.font=latarcyrheb-sun16 rhgb quiet net.ifnames=0 biosdevname=0"
# grub2-mkconfig -o /boot/grub2/grub.cfg

Update the network interface configuration file (here the initial interface name was enp2s0 and the new one is eth0):
#
在cd /etc/sysconfig/network-scripts目录下修改接口的名称，修改为eth格式
1、修改系统更新源（强烈建议更新，如果使用默认的系统源，会在安装过程中因为无法下载文件导致安装失败）
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
mv CentOS-Base.repoCentOS-Base.repo.bak
mv CentOS6-Base-163.repo CentOS-Base.repo
2、设置FQDN（使用all-in-one方式可以不做配置）
因为RDO的安装方式是通过puppet进行安装需要用到FQDN的命名方式，所以主机名要这样设置，名字可以随意取
[root@localhost~]#hostname controller
[root@localhost~]#vi /etc/hosts
10.23.21.71 controller
[root@localhost~]# hostname -f
controller
[root@localhost~]#reboot
3、关闭系统NetworkManager（In case your system is running with NetworkManager, you need to disable it.）
#systemctl stop NetworkManager
#systemctl disable NetworkManager
#systemctl enable network
4、安装openstack
Step 1: Software repositories
Update your current packages:
#sudo yum update -y
Setup the RDO repositories:
#sudo yum install -y https://rdoproject.org/repos/rdo-release.rpm
Step 2: Install Packstack Installer
#sudo yum install -y openstack-packstack
Step 3: Run Packstack to install OpenStack
Packstack takes the work out of manually setting up OpenStack. For a single node OpenStack deployment, run the following command.
#packstack --allinone
5、查看admin登录密码（安装时，admin密码是随机的）
[root@controller centos]# cat /root/keystonerc_admin
unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD=87269744dfcf4f70
export OS_AUTH_URL=http://10.23.21.71:5000/v2.0
export PS1='[\u@\h \W(keystone_admin)]\$ '
export OS_TENANT_NAME=admin
export OS_REGION_NAME=RegionOne
[root@controller centos]#
登录系统：http://$YOURIP/dashboard
