openstack制作centos6镜像

Posted 2020-10-06

 

 

做好系统后：

1.配置yum源：

yum -y install wget

cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.$(date +%F)
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

 

 

2.关闭SeLinux

sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config
grep SELINUX=disabled /etc/selinux/config
setenforce 0
或者直接编辑/etc/sysconfig/selinux,修改成SELINUX=disabled

 

3.使nova console-log 能将实例启动过程输出到实例启动日志中，就要在文件/boot/grub/menu.lst 中kernel参数中增加下面的内容：

kernel ...（省略n个参数）... console=tty0 console=ttyS0,115200n8

 

如下：

[[email protected] yum.repos.d]# cat /boot/grub/menu.lst 
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/vda2
#          initrd /initrd-[generic-]version.img
#boot=/dev/vda
default=0
timeout=1
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.32-431.el6.x86_64)
    root (hd0,0)
    kernel /vmlinuz-2.6.32-431.el6.x86_64 ro root=UUID=f0a5d467-5101-4a63-bc26-48682cac231b rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto LANG=zh_CN.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet console=tty0 console=ttyS0,115200n8
    initrd /initramfs-2.6.32-431.el6.x86_64.img

 

4.修改网络信息 /etc/sysconfig/network-scripts/ifcfg-eth0 （删掉mac信息)如下:

TYPE=Ethernet
 DEVICE=eth0
 ONBOOT=yes
 BOOTPROTO=dhcp
 NM_CONTROLLED=no 

做完后，重启网络服务

service network restart

 

5.   增加一行到/etc/sysconfig/network ：

NOZERCONF=yes

 

6、增加epel源

yum -y install epel-release

 

7.安装ACPI服务，能让宿主机对虚拟机进行开关机等电源管理操作
yum install acpid
chkconfig acpid on

yum install acpid  -y
chkconfig acpid on
service acpid start

8.安装和配置qemu-guest-agent

安装：

yum -y install qemu-guest-agent

配置：

8.1 编辑/etc/sysconfig/qemu-ga

TRANSPORT_METHOD="virtio-serial"

DEVPATH="/dev/virtio-ports/org.qemu.guest_agent.0"

LOGFILE="/var/log/qemu-ga/qemu-ga.log"               

PIDFILE="/var/run/qemu-ga.pid"

BLACKLIST_RPC=""

FSFREEZE_HOOK_ENABLE=0

8.2 将虚拟机关机，在虚拟机配置文件libvirt.xml中的<devices>下面添加下述配置，并重新启动虚拟机

用这条命令编辑

virsh edit centos6-raw

添加如下条目：

<channel type=‘unix‘>
  <source mode=‘bind‘ path=‘/var/lib/libvirt/qemu/org.qemu.guest_agent.0.centos6-raw.sock‘/>
  <target type=‘virtio‘ name=‘org.qemu.guest_agent.0‘/>
  <address type=‘virtio-serial‘ controller=‘0‘ bus=‘0‘ port=‘1‘/>
</channel>
<channel type=‘spicevmc‘>
  <target type=‘virtio‘ name=‘com.redhat.spice.0‘/>
  <address type=‘virtio-serial‘ controller=‘0‘ bus=‘0‘ port=‘2‘/>
</channel>

修改完后保存配置

 

8.3 启动qemu-ga

[[email protected] ~]# service qemu-ga restart
Stopping qemu-ga:                                          [  OK  ]
Starting qemu-ga:                                          [  OK  ]
[[email protected] ~]# chkconfig qemu-ga on
[[email protected] ~]# chkconfig --list|grep qemu-ga
qemu-ga         0:off   1:off   2:on    3:on    4:on    5:on    6:off

测试：

这个需要在开启状态下测试

 

8.关机

init 0

9.清理信息

virt-sysprep -d centos6-raw

 

10、上传镜像

glance image-create --name "centos6-raw" --file ./centos6-raw --disk-format raw --container-format bare --property hw_qemu_guest_agent=yes --visibility public --progress
