一、简介
Cobbler是红帽开发的批量部署系统的工具，对RHEL、CentOS支持完美，对其他发行版的linux部分支持，也不是很完美，本文介绍的是基于CentOS 7上安装Cobbler 2.6的文档。参照了网上的一些教程和官方文档，加上自己的实践，特别是分区部分，调试了数十次才算完美了。
二、安装CentOS 7 调整配置及安装相关软件
1、调整配置
安装完成后关闭selinux或参照cobbler官方文档设置selinux，http://cobbler.github.io/manuals/2.6.0/4/2_-_SELinux.html
[root@cobbler-server ~]# sed -i ‘/SELINUX/s/enforcing/disabled/’ /etc/selinux/config
重启服务器
关闭iptables以及取消开机启动，centos7 minimal没有安装ipables
关闭firewall或放行80 67 68 69 443 端口
80 443是cobbler web管理界面端口
67 68 是DHCP端口
69是TFTP端口
[root@cobbler-server ~]# systemctl stop firewalld
[root@cobbler-server ~]# systemctl disable firewalld
2、安装 epel 包
[root@cobbler-server ~]# yum install epel-release
[root@cobbler-server ~]# yum makecache
3、安装cobbler、cobbler-web 以及相关依赖软件
[root@cobbler-server ~]# yum install cobbler cobbler-web xinetd pykickstart cman dhcp -y
4、设置开机启动
[root@cobbler-server ~]# systemctl enable httpd
[root@cobbler-server ~]# systemctl enable dhcpd
[root@cobbler-server ~]# systemctl enable cobblerd
三、Cobbler、tftp、dhcp、rsync配置
1、TFTP配置
配置tftp绿色着色为修改后的值
[root@cobbler-server ~]# vim /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some 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 = 100 2
flags = IPv4
}
2、配置rsync
[root@cobbler-server ~]# systemctl enable rsyncd
CentOS7上安装cobbler 对于rsync无需额外配置
3、配置/etc/cobbler/settings
[root@cobbler-server ~]# cat /etc/cobbler/settings |grep ‘^[^#]’

4、修改/etc/cobbler/modules.conf
[root@cobbler-server ~]# cat /etc/cobbler/modules.conf |grep ‘^[^#]’
[authentication]
module = authn_configfile
[authorization]
module = authz_allowall
[dns]
module = manage_bind
[dhcp]
module = manage_isc #如果是dnsmasq就应该为manage_dnsmasq
[tftpd]
module = manage_in_tftpd
5、修改/etc/cobbler/dhcp.template
[root@localhost cobbler]# cat /etc/cobbler/dhcp.template |grep ‘^[^#]’
ddns-update-style interim;
allow booting;
allow bootp;
ignore client-updates;
set vendorclass = option vendor-class-identifier;
option pxe-system-type code 93 = unsigned integer 16;
subnet 192.168.11.0 netmask 255.255.255.0 {
option routers 192.168.11.252;
option domain-name-servers 192.168.11.252;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.11.100 192.168.11.200;
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
class “pxeclients” {
match if substring (option vendor-class-identifier, 0, 9) = “PXEClient”;
if option pxe-system-type = 00:02 {
filename “ia64/elilo.efi”;
} else if option pxe-system-type = 00:06 {
filename “grub/grub-x86.efi”;
} else if option pxe-system-type = 00:07 {
filename “grub/grub-x86_64.efi”;
} else {
filename “pxelinux.0”;
}
}
}
## group could be subnet if your dhcp tags line up with your subnets
## or really any valid dhcpd.conf construct … if you only use the
## default dhcp tag in cobbler, the group block can be deleted for a
## flat configuration
group {
#for mac in $dhcp_tags[$dhcp_tag].keys():
#set iface = $dhcp_tags[$dhcp_tag][$mac]
host $iface.name {
hardware ethernet $mac;
#if $iface.ip_address:
fixed-address $iface.ip_address;

## Cobbler defaults to $next_server, but some users
## may like to use $iface.system.server for proxied setups
next-server $next_server;
## next-server $iface.next_server;
}
#end for
}
6、重启cobbler httpd服务
[root@cobbler-server ~]# systemctl restart cobblerd
[root@cobbler-server ~]# systemctl restart httpd
更多详情见请继续阅读下一页的精彩内容： http://www.linuxidc.com/Linux/2017-10/147731p2.htm
四、检查cobbler配置
[root@cobbler-server ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : 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
Restart cobblerd and then run ‘cobbler sync’ to apply changes.
以上两点都可以忽略
第二点是修改部署系统默认的root密码
若提示enabled rsyncd or use systemctl to start rsyncd.service
是叫你把rsync加到开机启动
[root@cobbler-server ~]# systemctl enable rsyncd
执行以上命令后就不会出现这个提示了
五、导入镜像并查看导入情况
1、导入镜像
[root@cobbler-server ~]# mount /dev/cdrom /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
[root@cobbler-server ~]#cobbler import –path=/mnt/cdrom/ –name=Ubuntu-12.04.5 –arch=x86_64

*** TASK COMPLETE ***
有些镜像是不支持的，不支持就会导入错误
2、查看
查看导入的镜像和使用到的kickstart文件信息
[root@cobbler-server ~]# cobbler distro list

六、编辑seed文件
1、普通分区配置
[root@cobbler-server ~]# grep “^[^#]” /var/lib/cobbler/kickstarts/sample.seed
d-i debian-installer/locale string en_US
d-i console-setup/ask_detect boolean false
d-i keyboard-configuration/layoutcode string us
d-i keyboard-configuration/variantcode string
d-i netcfg/choose_interface select auto

d-i partman-auto/method string regular
d-i partman-auto/choose_recipe select fsm
d-i partman-lvm/device_remove_lvm boolean true
d-i partman-md/device_remove_md boolean true
d-i partman-auto/expert_recipe string \
fsm :: \

d-i preseed/late_command string wget -O- \
http://$http_server/cblr/svc/op/script/$what/$name/?script=preseed_late_default | \
chroot /target /bin/sh -s
2、lvm分区配置
绿色标记部分是最重要的，定制分区的配置，以上是普通分区方式
如果是lvm分区方式，用以下配置
d-i partman-auto/disk string /dev/sda#指定磁盘
d-i partman-auto/method string lvm#分区格式lvm还是普通分区还是raid
d-i partman-auto/choose_recipe select fsm
d-i partman-lvm/device_remove_lvm boolean true
d-i partman-md/device_remove_md boolean true
d-i partman-auto-lvm/no_boot boolean true
d-i partman-auto-lvm/new_vg_name string vg0
d-i partman-auto/expert_recipe string \
fsm :: \
1024 100% 1024 linux-swap method{ swap } \
format{ } $lvmok{ } lv_name{ swap } \
. \
2048 2048 2048 ext4 method{ lvm } \
$lvmok{ } mountpoint{ /home } lv_name{ home } \
format{ } use_filesystem{ } filesystem{ ext4 } \
. \
10240 10240 10240 ext4 method{ lvm } \
$lvmok{ } mountpoint{ / } lv_name{ root } \
format{ } use_filesystem{ } filesystem{ ext4 } \
options/relatime{ relatime } \
. \
768 1024 1024 ext4 method{ lvm } \
$lvmok{ } mountpoint{ /tmp } lv_name{ tmp } \
format{ } use_filesystem{ } filesystem{ ext4 } \
options/relatime{ relatime } \
. \
1 2048 1000000000 ext4 method{ lvm } \
$lvmok{ } mountpoint{ /www } lv_name{ www } \
format{ } use_filesystem{ } filesystem{ ext4 } \
options/relatime{ relatime } \
.
d-i partman-lvm/confirm_nooverwrite boolean true
d-i partman-lvm/confirm boolean true
d-i partman-partitioning/confirm_write_new_label boolean true
d-i partman/confirm_nooverwrite boolean true
d-i partman/confirm boolean true
d-i partman/choose_partition \
select Finish partitioning and write changes to disk #保存分区
注：
$lvmok{ }必须存在，不然安装会报错无法继续
不存在这个选项cobbler又会报错
{‘code’: u’VFFSL(SL,”lvmok”,True)’,
‘exc_val’: NotFound(u”cannot find ‘lvmok'”,),
‘lineCol’: (60, 11),
‘rawCode’: u’$lvmok’,
‘time’: ‘Sun Oct 9 23:43:14 2016’}]
不知道是不是cobbler的bug
七、注意事项
1、1 2048 1000000000 ext4 method{ lvm } \ 这三个数字分别代表最少1M ，权重，最多1000000000M
如果把剩余的都分配就用三个-1，即-1 -1 -1 ext4 method{ lvm } \
2、d-i partman-auto/choose_recipe select fsm：fsm随意命名，但必须和d-i partman-auto/expert_recipe string fsm :: 这个fsm对应
3、seed文件中不能有中文哪怕是注释，不然会报错
4、每次修改/etc/cobbler/setting配置后需要执行cobbler sync进行同步
5、对于esxi的支持，默认不支持esxi6，但是可以用esxi5的kickstart文件，部分不兼容，但仍能全自动安装
