openstack nova 关机 openstack

OpenStack
准备两台虚拟机设置两个节点分别为10节点和20 节点
10节点修改名称

[root@localhost ~]# hostnamectl set-hostname controller
[root@localhost ~]# bash

20节点

[root@localhost ~]# hostnamectl set-hostname computer
[root@localhost ~]# bash

配置网络

vi /etc/sysconfig/network-scripts/ifcfg-eno16777736两个节点的两个网卡都要配置

配置yum源
1挂载10节点

[root@controller ~]# mv /etc/yum.repos.d/C* /media/
[root@controller ~]# mkdir /opt/centos
[root@controller ~]# mkdir /opt/iaas
[root@controller ~]# mount -o loop CentOS-7-x86_64-DVD-1511.iso  /opt/centos
mount: /dev/loop0 is write-protected, mounting read-only
[root@controller ~]# mount -o loop XianDian-IaaS-v2.2.iso   /opt/iaas
mount: /dev/loop1 is write-protected, mounting read-only

2.配置

[root@controller ~]# vi /etc/yum.repos.d/local.repo
[centos]
name=centos
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[iaas]
name=iaas
baseurl=file:///ope/iaas/iaas-repo
gpgcheck=0
enabled=1

20节点
[root@computer ~]# vi /etc/yum.repos.d/ftp.repo
[centos]
