二、实验目的

准备好openstack组件安装前所需要的其他软件，如MariaDB，RabbitMQ等。

三、操作步骤

1. 修改所有节点/etc/hosts文件
   
   如果hosts文件中有将主机名解析到127.0.0.1的配置段，将其注销
2. 所有节点关闭NetworkManager
   [[email protected] ~]# systemctl stop NetworkManager.service
   [[email protected] ~]# systemctl disable NetworkManager.service
3. 所有节点添加openstack需要的yum源
   [[email protected] ~]# vim /etc/yum.repo.d/OpenStack-Queens.repo

   [OpenStack-Queens]
   name=OpenStack-Queens
   baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-queens/
   enable=1
   gpgcheck=0

4. 安装NTP服务
   controller节点进行以下操作：
   [[email protected] ~]# yum install chrony
   [[email protected] ~]# vim /etc/chrony.conf

   allow 172.16.80.0/24

   [[email protected] ~]# systemctl enable chronyd.service
   [[email protected] ~]# systemctl start chronyd.service
   [[email protected] ~]# chronyc sources
   
   其他节点进行以下操作：
   [[email protected] ~]# yum install chrony
   [[email protected] ~]# vim /etc/chrony.conf

   server controller iburst

   [[email protected] ~]# systemctl enable chronyd.service
   [[email protected] ~]# systemctl start chronyd.service
   [[email protected] ~]# chronyc sources
