1、安装系统，Centos7镜像采用CentOS-7.0-1406-x86_64-Minimal.iso
分区/、boot、swap，然后单独拿出一个分区，供cinder使用。

2、系统环境准备工作

  1. yum install -y net-tools wget screen
  2.  
  3. [root@juno ~]# more /etc/hosts
  4. 127.0.0.1   juno localhost localhost.localdomain localhost4 localhost4.localdomain4
  5. ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  6. 192.168.3.97    juno
  7. [root@juno yum.repos.d]# more /etc/resolv.conf
  8. # Generated by NetworkManager
  9. nameserver 8.8.8.8
  10. [root@juno yum.repos.d]# cd /etc/sysconfig/network-scripts/
  11. vi ifcfg-enp3s0
  12. vi ifcfg-enp5s2
  13. [root@juno network-scripts]# more /etc/sysconfig/network
  14. # Created by anaconda
  15. NETWORKING=yes
  16. HOSTNAME=juno
  17. GATEWAY=192.168.3.1
  18.  
  19. [root@juno yum.repos.d]# systemctl disable NetworkManager
  20. rm '/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service'
  21. rm '/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service'
  22. rm '/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
  23. [root@juno yum.repos.d]# systemctl stop NetworkManager
  24.  
  25. vi /etc/selinux/config # SELINUX=enforcing SELINUX=disabled
  26. setenforce 0
  27.  
  28. yum install -y lvm2
  29.  
  30. [root@juno ~]# df -h
  31. /dev/sda2       855G  1.2G  810G    1% /
  32. devtmpfs        7.7G     0  7.7G    0% /dev
  33. tmpfs           7.7G     0  7.7G    0% /dev/shm
  34. tmpfs           7.7G  8.6M  7.7G    1% /run
  35. tmpfs           7.7G     0  7.7G    0% /sys/fs/cgroup
  36. /dev/sda5        48G   53M   46G    1% /data
  37. /dev/sda1       190M  106M   71M   61% /boot
  38. [root@juno ~]# umount /dev/sda5
  39. [root@juno ~]# pvcreate /dev/sda5
  40. Physical volume "/dev/sda5" successfully created
  41. [root@juno ~]#  vgcreate cinder-volumes /dev/sda5
  42. Volume group "cinder-volumes" successfully created
  43.  去掉/dev/sda5在/etc/fstab中的启动项

3、准备rdo安装环境

  1. yum install -y http://rdo.fedorapeople.org/openstack-juno/rdo-release-juno.rpm   #会在/etc/yum.repos.d目录增加rdo-release.repo源文件。
  2.  
  3. yum install -y openstack-packstack  
  4.  
  5. [root@juno yum.repos.d]# more /etc/redhat-release
  6. CentOS Linux release 7.0.1406 (Core)
  7. [root@juno yum.repos.d]# yum update -y  #会在/etc/yum.repos.d目录增加CentOS-fasttrack.repo源文件。
  8.  
  9. 更新完系统，执行重启
  10. reboot
  11.  
  12. [root@juno ~]# packstack --gen-answer-file=juno.txt 创建应答文件
  13. Packstack changed given value  to required value /root/.ssh/id_rsa.pub

4、修改应答文件，因为测试环境所限，我是单独节点安装所有模块测试，网络模式采用VLAN，应答文件如下

  1. [root@juno ~]# more juno.txt |grep "^\s*[^# \g].*$" |more
