一、Cobbler介绍
1.1 关于Cobbler
Cobbler是一个快速网络安装linux的服务,而且在经过调整也可以支持网络安装windows。该工具使用python开发,小巧轻便(才15k行python代码),使用简单的命令即可完成PXE网络安装环境的配置,同时还可以管理DHCP、DNS、以及yum仓库、构造系统ISO镜像。Cobbler支持命令行管理,web界面管理,还提供了API接口,可以方便二次开发使用。Cobbler客户端Koan支持虚拟机安装和操作系统重新安装,使重装系统更便捷。 Cobbler提供以下服务集成:* PXE服务支持* DHCP服务管理* DNS服务管理* 电源管理* Kickstart服务支持* yum仓库管理1.2 谁在使用Cobbler

1.3 系统版本支持
Cobbler最初是支持系统版本Fedora, Red Hat和衍生版本,如CentOS 和Scientific Linux.现在对Debian 和Ubuntu SuSE支持也相当强。还支持FreeBSD、ESXI等。koan 在Fedora, Red Hat Enterprise Linux, or CentOS工作正常,其他Linux版本应该也不错。1.4 Cobbler 模型

3.3 配置Cobbler
vim /etc/cobbler/settings #Cobbler主配置文件 sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings sed -i 's/manage_rsync: 0/manage_rsync: 1/g' /etc/cobbler/settings
配置前后内容对比 diff /etc/cobbler/settings /etc/cobbler/settings_2013-03-10 218c218 <manage_dhcp: 1 #启用cobbler管理DHCP功能 --- > manage_dhcp: 0 237c237 <manage_rsync: 1 #启用cobbler管理rsync功能 --- > manage_rsync: 0 248c248 <next_server: 172.17.10.14 # DHCP服务地址 --- > next_server: 127.0.0.1 360c360 <server: 172.17.10.14 # cobbler服务地址 --- > server: 127.0.0.13.4 检查、关闭SELinux、iptables
getsebool getsebool: SELinux is disabled service iptables stop Flushing firewall rules: [ OK ] Setting chains to policy ACCEPT: filter [ OK ] Unloading iptables modules: [ OK ] chkconfig iptables off
3.5 配置tftp、rsync
设置 'disable' 为 'no'
sed -i '/disable/c\\tdisable\t\t\t= no' /etc/xinetd.d/tftp
sed -i 's/\=\ yes/\=\ no/g' /etc/xinetd.d/rsync
3.6 启用wsgi模块
sed -i 's@#LoadModule@LoadModule@g' /etc/httpd/conf.d/wsgi.conf
3.7 生成Cobbler安装系统root初始密码
这里生成密钥和配置默认密钥,ks文件引用 openssl passwd -1 -salt 'random-phrase-here' 'hexun' $1$random-p$Q1IN9LaNg7yhRKJuY50fV1s 加入cobbler配置 vim /etc/cobbler/settings grep default_password_crypted /etc/cobbler/settings#修改为如下配置 default_password_crypted: "$1$random-p$Q1IN9LaNg7yhRKJuY50fV1s"
3.8配置DHCP
cp /etc/cobbler/dhcp.template /etc/cobbler/dhcp.template.$(date +%F) #备份 vim /etc/cobbler/dhcp.template dhcp.template dhcp.template.2013-03-10 vim /etc/cobbler/dhcp.template #编辑 diff /etc/cobbler/dhcp.template /etc/cobbler/dhcp.template.2013-03-10 |grep '<' #配置前后差异对比 < subnet 172.17.0.0 netmask 255.255.0.0 { < option routers 172.17.10.119; < option domain-name"sys.hexun"; < option domain-name-servers 172.17.10.2; < option subnet-mask 255.255.0.0; < range dynamic-bootp 172.17.188.60 172.17.188.120; < default-lease-time 600; < max-lease-time 1200;
3.9 配置相关服务开机自启动
/sbin/service httpd start /sbin/service dhcpd start /sbin/service xinetd start /sbin/service cobblerd start /sbin/chkconfig httpd on /sbin/chkconfig dhcpd on /sbin/chkconfig xinetd on /sbin/chkconfig tftp on /sbin/chkconfig cobblerd on
3.10 下载引导操作系统文件
cobbler get-loaders
3.11 配置debmiror
yum -y install debmirror 修改 /etc/debmirror.conf 配置文件,注释掉 @dists 和 @arches 两行 sed -i 's|@dists=.*|#@dists=|' /etc/debmirror.conf sed -i 's|@arches=.*|#@arches=|' /etc/debmirror.conf
3.12 检查Cobbler 配置
cobbler check No configuration problems found. All systems go. #出现此提示即正常 cobblerd does not appear to be running/accessible #此提示是因为cobbler服务没启动cobbler check出现的相关报错处理请看http://dreamway.blog.51cto.com/blog/1281816/1167078
