<一,openStack img 制作>
tips:制作大部分cloud platforms img准备工作.
<1,>
一台linux系统(最好centOS6 根据当前cloud platform and linux OS compatibility)的机器,作为制作镜像的机器.
1,安装底层支持软件包
yum groupinstall Virtualization libvirt virt-install qemu-kvm;
2,某种类型 的iso文件准备
3,启动libvirtd
<2,>开始制作镜像
qemu-img create -f qcow2 ruiyCentOS-openStack.qcow2 30G
chown qemu:qemu *.qcow2 -R
virt-install -n RuiyCnetOSimg -r 4096 --cpu host -c /images/Centos-*iso --disk path=*.qcow2,device=disk,bus=virtio,size=30,format=qcow2 --vnc --vncport=5978 --vnclisten=0.0.0.0 -v
为openStack的镜像而打磨一下我们刚装好的系统
virsh start/destroy/undefine VMInames;
1,delete /etc/udev/rules.d/70-persistent-net.rules (删除以生成的网络设备规则!)
2,删除ifcfg-eth0的HWADDR一行
/etc/sysconfig/network-scripts/ifcfg-eth0内容如下:
DEVICE="eth0"
BOOTPROTO="dhcp"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
3,关闭firewall和selinux/config
sed -i s/^SELINUX=.*/SELINUX=disabled/g /etc/selinux/config
service iptables stop && chkconfig iptables off;
设置系统能自动获取openstack指定的hostname和ssh-key
使用vim编辑/etc/rc.local文件
然后将以下内容输入进去，放在”touch /var/lock/subsys/local”之前
| if [ ! -d /root/.ssh ]; then mkdir -p /root/.ssh chmod 700 /root/.ssh fi # Fetch public key using HTTP ATTEMPTS=30 FAILED=0 while [ ! -f /root/.ssh/authorized_keys ]; do curl -f http://169.254.169.254/latest/meta-data/hostname > /tmp/metadata-hostname 2>/dev/null else |
1,quick guide to creating a OpenStack bootable image;
1.1 wget os iso
wget http://releases.ubuntu.com/14.04/ubuntu-14.04-server-adm64.iso
1.2 create disk image:
qemu-img create -f qcow2 ubuntu-14.04-server.qcow2 30G
1.3 using KVM,launch an instance using iso and disk image (4096Mb ram and 2 processors)
kvm -hda ubuntu-14.04-server.qcow2 -cdrom ubuntu-14.04-server-adm64.iso -m 4096 -smp 2
1.4 upload the image to glance:
glance image-create --name ubuntu-14.04-server --disk-format=qcow2 --container-format=bare --is-public=True < ubuntu-14.04-server.qcow2
1.5 boot
nova boot --image ubuntu-14.04-server --flavor 3 VMI001
(Tips:delete /etc/udev/rules.d/70-persistent-net.rules (beforce uploading the image to glance))
in order for the nic interface ordering to start at eth0,otherwise it will start eth1.... which might not automatically start a dhcp-client on the interface.
