OpenStack云计算平台部署(单节点)

环境配置

虚拟机（centos7 、内存8G、硬盘300G、处理器4核并开启intel vt-x，网络模式设置为NAT，虚拟机网络一定要设置好，并可以ping通baidu，不然有中途掉IP的情况发生）

关闭防火墙和selinux

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
vi /etc/selinux/config
修改SELINUX=disabled

关闭Network管理服务

systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl start network
systemctl enable network
reboot

删除所有的yum源并重新下载yum源，并更新yum源

cd /etc/yum.repos.d/
ls
rm -rf *
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
ls
yum clean all
yum makecache
yum -y update

安装ntp时间同步服务器，并同步时间及写入计划任务

yum -y install ntpdate
ntpdate ntp.aliyun.com
crontab -e
写入：*/2 * * * * /usr/sbin/ntpdate ntp.aliyun.com >> /var/log/ntpdate.log
crontab -l
systemctl restart crond
systemctl enable crond
#安装openstack-train版本
yum -y install centos-release-openstack-train.noarch
#或安装openstack queens版本
yum install -y centos-release-openstack-queens

安装openstack-packstack软件包

yum -y install openstack-packstack

执行packstack --allinone命令进行安装

packstack --allinone 或 packstack -d --allinone
#执行结果如下：
