最近工作忙,好久没写博客,现在正好有空介绍一下我这里使用私有云的经验。

现在分享一下如何使用oz自动化制作openstack镜像,下面有我自己制作centos 6.4 6.5 6.7 7.2与ubuntu 12.04.5与14.04.4的模板,模板也存放到github里,地址是https://github.com/dl528888/oz_create_openstack_image_templates。

之前使用镜像要不使用别人做好的,要不是自己制作,但很麻烦,现在使用oz可以简化操作,定制一个模板(类似cobbler)的就可以自动化制作了,十分方便。

官方地址是 https://github.com/clalancette/oz/

下面是介绍如何安装

1、安装epel源

rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm yum install -y oz

如果还是没有生效,可以使用下面的配置在安装

[epel] name=Extra Packages for Enterprise linux 6 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch baseurl=http://mirrors.sohu.com/fedora-epel/6/$basearch ##mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

2、启动虚拟网络

virsh net-start default

如果出现下面错误

错误:开始网络 default 失败 错误:internal error Child process (/usr/sbin/dnsmasq --strict-order --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --bind-interfaces --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override --dhcp-hostsfile=/var/lib/libvirt/dnsmasq/default.hostsfile --addn-hosts=/var/lib/libvirt/dnsmasq/default.addnhosts) unexpected exit status 2: dnsmasq: failed to set SO_REUSE{ADDR|PORT} on DHCP socket: Protocol not available

查看一下dnsmasq的版本,如果是2.48就升级

14:12:07 # rpm -qa|grep dnsmasq dnsmasq-2.48-16.el6_7.x86_64

升级方法如下

yum install -y gcc wget http://www.thekelleys.org.uk/dnsmasq/dnsmasq-2.75.tar.gz tar zxvf dnsmasq-2.75.tar.gz cd dnsmasq-2.75 make V=s mv /usr/sbin/dnsmasq /usr/sbin/dnsmasq_back cp src/dnsmasq /usr/sbin/ service dnsmasq stop virsh net-start default

再查看应该有个桥接网卡virbr0启动,ip是192.168.122.1

如果遇到下面错误

01:56:22 # virsh net-start default error: Failed to reconnect to the hypervisor error: no valid connection error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory

解决的方法是

service libvirtd start

3、上传或下载镜像

如果当前已有下载好的镜像,可以使用上传到oz所在服务器里,如果没有可以在线下载,下面是介绍如果下降镜像到服务器里。

rsync -avz --progress mirror.nsc.liu.se::centos-store/6.5/isos/x86_64/CentOS-6.5-x86_64-bin-DVD1.iso /mnt/iso/

默认国内是只有最新的版本,旧版本只能从国外下载或通过bt下载

4、编写模板

模板我都写完了,大家可以直接使用或在我模板上修改

所有模板都在存放到/etc/oz/conf里

A、制作centos 6.4 x86_64系统的

centos64.tdl配置

<template> <name>CentOS-6.4-x86_64</name> <disk> <size>20</size> </disk> <os> <name>CentOS-6</name> <version>4</version> <arch>x86_64</arch> <install type='iso'> <iso>file:///mnt/iso/CentOS-6.4-x86_64-bin-DVD1.iso</iso> </install> </os> <description>CentOS 6.4 x86_64</description> <commands> <command name='update'> sed -i '/^HWADDR/d' /etc/sysconfig/network-scripts/ifcfg-eth0 sed -i '/UUID/d' /etc/sysconfig/network-scripts/ifcfg-eth0 echo -n > /etc/udev/rules.d/70-persistent-net.rules </command> </commands> </template>

centos64.ks配置

install text key --skip keyboard us lang en_US.UTF-8 skipx network --device eth0 --bootproto dhcp rootpw denglei2016 firewall --disabled authconfig --enableshadow --enablemd5 selinux --disabled timezone --utc Asia/Chongqing bootloader --location=mbr --append="console=tty0 console=ttyS0,115200" zerombr yes clearpart --all part / --fstype ext4 --size=19768 --grow reboot %post rm -rf /etc/yum.repos.d/* cat <<EOL > /etc/yum.repos.d/CentOS6.repo # CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.

This is a soft error so we'll continue" fi rm -f /tmp/metadata-hostname sed -i '/instance_init/d' /etc/rc.d/rc.local rm -rf /usr/local/bin/instance_init.sh else FAILED=\$((\$FAILED + 1)) if [ \$FAILED -ge \$ATTEMPTS ]; then echo "Failed to retrieve public key from instance metadata after \$FAILED attempts, quitting" break fi echo "Could not retrieve public key from instance metadata (attempt #\$FAILED/\$ATTEMPTS), retrying in 5 seconds..." sleep 5 fi done EOF rm -rf /var/log/yum.log rm -rf /var/lib/yum/* rm -rf /root/install.log rm -rf /root/install.log.syslog rm -rf /root/anaconda-ks.cfg rm -rf /var/log/anaconda* rm -rf /tmp/yum.log rm -rf /tmp/ks-script-* %packages --nobase --excludedocs openssh-server openssh-clients python acpid wget vim

默认的root密码是denglei2016。

下面是自动化制作

命令如下

oz-install -p -u -d3 -a centos64.ks centos64.tdl -x /tmp/centos64.xml

下面是运行结果

[[email protected] finish]# ll /var/lib/libvirt/images/CentOS-6.4-x86_64.qcow2 -rw-rw-rw-. 1 root root 1219493888 Jul 20 10:58 /var/lib/libvirt/images/CentOS-6.4-x86_64.qcow2 [[email protected] finish]# du -sh /var/lib/libvirt/images/CentOS-6.4-x86_64.qcow2 1.2G /var/lib/libvirt/images/CentOS-6.4-x86_64.qcow2

当前是1.2G,下面压缩一下

压缩命令是

qemu-img convert -c /var/lib/libvirt/images/CentOS-6.4-x86_64.qcow2 -O qcow2 /tmp/CentOS-6.4-x86_64.qcow2

运行结果

[[email protected] finish]# ll /tmp/CentOS-6.4-x86_64.qcow2 -rw-r--r--. 1 root root 268037120 Jul 20 11:00 /tmp/CentOS-6.4-x86_64.qcow2 [[email protected] finish]# du -sh /tmp/CentOS-6.4-x86_64.qcow2 256M /tmp/CentOS-6.4-x86_64.qcow2

可以看到从1.2G压缩到了256M,压缩了差不多4/5.

B.制作centos6.5 x86_64

下面是模板配置

centos65.tdl配置

<template> <name>CentOS-6.5-x86_64</name> <disk> <size>20</size> </disk> <os> <name>CentOS-6</name> <version>5</version> <arch>x86_64</arch> <install type='iso'> <iso>file:///mnt/iso/CentOS-6.5-x86_64-bin-DVD1.iso</iso> </install> </os> <description>CentOS 6.5 x86_64</description> <commands> <command name='update'> sed -i '/^HWADDR/d' /etc/sysconfig/network-scripts/ifcfg-eth0 sed -i '/UUID/d' /etc/sysconfig/network-scripts/ifcfg-eth0 echo -n > /etc/udev/rules.d/70-persistent-net.rules </command> </commands> </template>

下面是centos65.ks配置

制作命令

oz-install -p -u -d3 -a ubuntu_12.04.5.ks ubuntu_12.04.5.tdl -x /tmp/ubuntu12.04.5.xml -t 3000

请注意制作ubuntu镜像需要把超时时间延迟,默认是1200s,由于安装库太多,默认超时时间不足,会导致制作失败,需要延长到3000s。
