操作指导： 本文主要安装L版openstack，采用yum安装方式。 只有“#”的命令行表示在所有的节点均进行操作；命令行有主机名的表示仅在该主机上进行操作。 另外，官方文档时间同步采用的是chrony，本文仍采用ntp服务。服务器部署
系统环境

[root@compute ~]# crontab -l*/5 * * * * /usr/sbin/ntpdate 192.168.1.11 >/dev/null 2>&1关闭防火墙
# systemctl stop firewalld关闭selinux
# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config //需要重启才能生效安装基础包
[root@controller ~]# yum install -y http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm[root@controller ~]# yum install -y centos-release-openstack-liberty[root@controller ~]# yum install -y python-openstackclient安装mysql

安装rabbitmq
