一、簡介

Cobbler是紅帽開發的批次部署系統的工具，對RHEL、CentOS支援完美，對其他發行版的linux部分支援，也不是很完美，本文介紹的是基於CentOS 7上安裝Cobbler 2.6的文件。參照了網上的一些教學和官方文件，加上自己的實踐，特別是分割區部分，偵錯了數十次才算完美了。

二、安裝CentOS 7 調整設定及安裝相關軟體

1、調整設定

安裝完成後關閉selinux或參照cobbler官方文件設定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  

重新啟動伺服器

關閉iptables以及取消開機啟動，centos7 minimal沒有安裝ipables

關閉firewall或放行80 67 68 69 443 埠

80 443是cobbler web管理介面埠

67 68 是DHCP埠

69是TFTP埠

[root@cobbler-server ~]# systemctl stop firewalld

[root@cobbler-server ~]# systemctl disable firewalld

2、安裝 epel 包

[root@cobbler-server ~]# yum install epel-release

[root@cobbler-server ~]# yum makecache

3、安裝cobbler、cobbler-web 以及相關依賴軟體

[root@cobbler-server ~]# yum install cobbler cobbler-web xinetd pykickstart cman dhcp -y

4、設定開機啟動

[root@cobbler-server ~]# systemctl enable httpd

[root@cobbler-server ~]# systemctl enable dhcpd 

[root@cobbler-server ~]# systemctl enable cobblerd

三、Cobbler、tftp、dhcp、rsync設定

1、TFTP設定

設定tftp綠色著色為修改後的值

[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、設定rsync

[root@cobbler-server ~]# systemctl enable rsyncd

CentOS7上安裝cobbler 對於rsync無需額外設定

3、設定/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就應該為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;

        #end if

        #if $iface.hostname:

        option host-name "$iface.hostname";

        #end if

        #if $iface.netmask:

        option subnet-mask $iface.netmask;

        #end if

        #if $iface.gateway:

        option routers $iface.gateway;

        #end if

        #if $iface.enable_gpxe:

        if exists user-class and option user-class = "gPXE" {

            filename "http://$cobbler_server/cblr/svc/op/gpxe/system/$iface.owner";

        } else if exists user-class and option user-class = "iPXE" {

            filename "http://$cobbler_server/cblr/svc/op/gpxe/system/$iface.owner";

        } else {

            filename "undionly.kpxe";

        }

        #else

        filename "$iface.filename";

        #end if

        ## 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、重新啟動cobbler httpd服務

[root@cobbler-server ~]# systemctl restart cobblerd

[root@cobbler-server ~]# systemctl restart httpd
