rhel6上的cobbler部署

看了别人的cobbler文章想试试，突发奇想在rhel6上做了一下。与rhel5相比还是小有区别的，写出来大家看看。

默认的yum源里找不到cobbler何其相关软件，先安装rpmforge这个第三方源。

在rhel6下rpmforge软件少点，还得从网上单独下载cobbler的rpm包。

rhel61上安装的是2.0.11的版本。

服务端用到的软件包如下：

rpmforge-release-0.5.2-2.el6.rf.i686.rpm

cobbler （rpmforge提供）

python-cheetah （rpmforge提供）

python-yaml （rpmforge提供）

libyaml （rpmforge提供）

dhcp

xinetd

tftp-server

createrepo

mod_wsgi

python-devel

deltarpm

python-deltarpm

genisoimage

客户端用到的软件包：

koan （rpmforge提供）

1. 部署方法：

安装上述软件，不会装的到这里不用看了。

2. 检查cobbler配置：

#service cobblerd start ; service httpd start #需要先启动这两个服务才能检查。

1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.

2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.

3 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.

4 : change 'disable' to 'no' in /etc/xinetd.d/tftp

5 : change 'disable' to 'no' in /etc/xinetd.d/rsync

6 : debmirror package is not installed, it will be required to manage debian deployments and repositories

7 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one

8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

处理上述问题。这个和老版本有些许区别，有的功能我们是不需要的，不要纠结全部解决。

3. 导入：

#mount /dev/cdrom /media

#cobbler import --path=/media/ --name=rhel61 --arch=i386

4. 修改DHCP和kickstart配置模板：

#vi /var/lib/cobbler/kickstarts/default.ks

#cat /etc/cobbler/dhcp.template > /etc/dhcp/dhcpd.conf

注意nextserver和filename；本服务器的IP地址要和dhcp配置的subnet一个网段，否则会启动失败。

5. 同步配置：

#cobbler sync

6. 启动有关服务：
