一.简介
Cobbler 可以用来快速建立 Linux 网络安装环境，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会。（~..~）
二.安装环境以及资源
系统：centos 6.5 IP：192.168.30.158/24
自动安装镜像：CentOS-6.5-x86_64-bin-DVD1.iso
三.安装步骤
安装epel源：
[root@cobbler ~]# rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
安装DHCP、tftp，rsync，xinetd，httpd（这些都是所需要的，如果有则不需要安装。）
[root@cobbler ~]#yum-yinstalldhcp tftp rsync xinetd httpd
安装cobbler
[root@cobbler ~]# wgethttp://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
[root@cobbler ~]# rpm -ivh rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
[root@cobbler ~]# yum install cobbler
安装cobbler完成后，重启cobblerd。还暂时不能使用，我们可以运行一下这个命令，检查一下。可以看到的错误信息
[root@cobbler ~]# cobbler checkThe following are potential configuration items that you may want to fix:
1: The'server'fieldin/etc/cobbler/settings must be set to something other than localhost,or kickstarting features will not work. This should be a resolvablehostnameor IPforthe boot server as reachable by all machines that will use it.
2: For PXE to be functional,thenext_serverin/etc/cobbler/settings must be set to something other than127.0.0.1,and should match the IP of the boot server on the PXE network.
3: changedisable'tono'in/etc/xinetd.d/tftp
4: some network boot-loaders are missing from /var/lib/cobbler/loaders,you may runcobbler get-loaders'to download them,or,ifyou 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. Filesinthis directory,should you want to support all architectures,should include pxelinux.0,menu.c32,elilo.efi,and yaboot. The'command is the easiest way to resolve these requirements.
5: changein/etc/xinetd.d/rsync
6: comment outdists'on /etc/debmirror.confforproper debian support7: comment outarches8: The default password used by the sample templatesfornewly installed machines (default_password_cryptedin/etc/cobbler/settings) is still set tocobbler'and should be changed,try:"openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'"to generate new oneRestart cobblerd andthenruncobbler sync'to apply changes.
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.
上面提示需要修改cobbler服务器的ip地址。配置文件是/etc/cobbler/settings.找到[root@cobbler ~]# vim /etc/cobbler/settingsserver:192.168.30.158next_server:30.158
2 : change 'disable' to 'no' in /etc/xinetd.d/tftp 修改disable 为 no
[root@cobbler ~]#vi/etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivialfiletransfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations,download configuration files to network-aware printers,\
# and to start the installation processforsome operating systems.
service tftp{
socket_type = dgram
protocol = udp
wait= yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable =no
per_source =11
cps =1002
flags = IPv4
}
3 : some network boot-loaders are missing from /var/lib/cobbler/loaders,you may run 'cobbler get-loaders' to download them,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 include pxelinux.0,and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.

4 : 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
[root@cobbler ~]# opensslpasswd-1-salt222222999999'
$1$222222$D38AxheCTHf/nVAzlN0.z0
此处按提示操作，最后一个生成的“999999”密码，是cobbler客户端安装完系统后的root密码。生成后的密码$1$222222$D38AxheCTHf/nVAzlN0.z0需要写入下面的文件内：/etc/cobbler/settings内
[root@cobbler ~]# vim /etc/cobbler/settings
default_password_crypted:$1$222222$D38AxheCTHf/nVAzlN0.z0"
5 : comment out 'dists' on /etc/debmirror.conf for proper debian support；comment out 'arches' on /etc/debmirror.conf for proper debian support
[root@cobbler ~]# vim /etc/debmirror.conf#@dists=sid";#@arches=i386";
找到以上两行，并注释掉这两句。
6: change 'disable' to 'no' in /etc/xinetd.d/rsync 修改disable 为 no
[root@cobbler ~]#vi/etc/xinetd.d/rsync
# default: off
# description: The rsync server is a good addition to anftpserver,as it \
# allows crc checksumming etc.
service rsync
{
disableno
flags = IPv6
socket_type = stream
wait= no
user = root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
7：将上述错误修改完毕后，重启下cobblerd服务，再次运行cobbler check检查，出现以下便表示前面几条的提示已经被解决了。
[root@cobbler ~]# service cobblerd restart
Stopping cobbler daemon: [ OK ]
Starting cobbler daemon: [ OK ]
[root@cobbler ~]# cobbler checkNo configuration problems found. All systems go.
[root@cobbler ~]#vi/etc/cobbler/settingsmanage_dhcp:1
9：修改DHCP配置模板，修改成如下配置（根据自己的网络环境配置）
[root@cobbler ~]#vi/etc/cobbler/dhcp.template
subnet30.0netmask255.255.255.0{
option routers30.1;
option domain-name-servers30.1;
option subnet-mask255.0;
range dynamic-bootp30.10030.254;
default-lease-time21600;
max-lease-43200;
next-server $next_server;
10：安装光盘已经放在光驱里了，现在需要创建文件，然后挂载到电脑上。
[root@cobbler ~]#mkdir-p /cobbler/ISO
[root@cobbler /]#mount/dev/cdrom /cobbler/ISO/
mount: block device /dev/sr0 iswrite-protected,mounting read-only
之后导入安装镜像。
[root@cobbler ~]# cobbler import --path=/cobbler/ISO/ --name=CentOS-6.5_86x64
