8、手动创建Openstack Centos虚拟机

1、安装环境

yum install -y qemu-kvm libvirt

yum install -y virt-install

systemctl enable libvirtd

systemctl start libvirtd

 

2、创建一个虚拟机磁盘

qemu-img create -f qcow2 /tmp/centos7.2.qcow2 10G

 

3、安装一台虚拟机

virt-install --virt-type kvm --name centos --ram 1024 \
  --disk /tmp/centos7.2.qcow2,format=qcow2 \
  --network network=default \
  --graphics vnc,listen=0.0.0.0 --noautoconsole \
  --os-type=linux --os-variant=centos7.0 \
  --location=/tmp/CentOS-7-x86_64-DVD-1511.iso

4、启动

virsh list --all

virsh start centos7.2

5、安装默认需要的软件

net-tools   tree scree wget  git   vim salt-minion zabbix-agent  lrzsz

6、修改网卡

TYPE=Ethernet
BOOTPROTO=dhcp
IPV4_FAILURE_FATAL=no
NAME=eth0
DEVICE=eth0
ONBOOT=yes

7、关闭防火墙、NetworkManager、selinux、postfix

systemctl stop firewalld
systemctl disable firewalld
systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl stop postfix
systemctl disable postfix

vim /etc/sysconfig/

SELINUX=disable

8、上传开启配置脚本

scp init-v1.sh 192.168.122.221:/tmp

9、编辑脚本

echo  "GATEWAY=192.168.90.1" >> $NET_FILE

10、拷贝rc.local文件

cp /etc/rc.d/rc.local /tmp

11、设置开机启动并赋予执行权限

vim /etc/rc.local

/bin/bash /tmp/init-v1.sh

chmod +x /tmp/init-v1.sh

chomod +x /etc/rc.d/rc.local

12、关机上传镜像到glance

openstack image create "CentOS-7.4-x86_64" \
  --file /tmp/centos7.4.qcow2 \
  --disk-format qcow2 --container-format bare \
  --public

13、在控制台选择镜像创建虚拟机
