CentOS7 使用RDO部署单节点Train版OpenStack
| IP地址 | 主机名 | 节点 |
| 192.168.200.135 | openstack | All-in-One |
(1)创建一台虚拟机，节点为192.168.200.135，更改主机名为openstack
[root@localhost ~]# hostnamectl set-hostname openstack
[root@localhost ~]# bash
[root@openstack ~]#(2)禁用防火墙与SELinux
[root@openstack ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@openstack ~]# systemctl stop firewalld
[root@openstack ~]# vi /etc/selinux/config
SELINUX=disabled
[root@openstack ~]# setenforce 0注意：未禁用SELinux会导致部署openstack时systemctl start httpd失败报错
(3)停用与OpenStack组件有冲突的NetworkManager服务，使用network服务
[root@openstack ~]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.
Removed symlink /etc/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
[root@openstack ~]# systemctl stop NetworkManager
[root@openstack ~]# systemctl enable network
network.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig network on
[root@openstack ~]# systemctl start network(4)修改hosts配置文件
[root@openstack ~]# vi /etc/hosts
192.168.200.135 openstack(5)配置使用阿里源
[root@openstack ~]# mkdir /root/old_repo
[root@openstack ~]# mv /etc/yum.repos.d/* /root/old_repo
[root@openstack ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo(6) 设置时间同步
[root@openstack ~]# yum install -y chrony
[root@openstack ~]# vi /etc/chrony.conf
server ntp1.aliyun.com iburst //增加使用阿里云网络授时NTP服务器
[root@openstack ~]# timedatectl set-timezone "Asia/Shanghai" //修改时区(7) 设置OpenStack-train库，因为CentOS官方源停止维护，将下载下来的repo文件中的官方源手动修改为阿里源
[root@openstack ~]# yum -y install centos-release-openstack-train或者直接将/etc/yum.repos.d/中相对应的repo文件手动替换
https://download.csdn.net/download/m0_75102488/92265954
https://download.csdn.net/download/m0_75102488/92265954
(8) 安装Packstack安装器
[root@openstack ~]# yum -y install openstack-packstack
[root@openstack ~]# yum install -y python2-qpid-proton-0.26.0-2.el7.x86_64
[root@openstack ~]# packstack --gen-answer-file=/root/openstack-train-answer-file.txt //产生应答文件模板
Packstack changed given value to required value /root/.ssh/id_rsa.pub
Additional information:* Parameter CONFIG_NEUTRON_L2_AGENT: You have chosen OVN Neutron backend. Note that this backend does not support the VPNaaS or FWaaS services. Geneve will be used as the encapsulation method for tenant networks[root@openstack ~]# vi /root/openstack-train-answer-file.txt
# Specify 'y' to provision for demo usage and testing. ['y', 'n']
CONFIG_PROVISION_DEMO=n注意：需要将应答文件中下载DEMO的选项关闭，未关闭会导致部署openstack时在Applying 192.168.200.135_controller.pp中提示下载超时
(9) 运行Packstack安装Openstack
[root@openstack ~]# packstack --answer-file=/root/openstack-train-answer-file.txtWelcome to the Packstack setup utility
