一、關閉selinux
1、修改配置
vim /etc/selinux/config
SELINUX=enforcing
SELINUXTYPE=targeted
SELINUX=disabled
2、配置生效
setenforce 0
二、關閉防火墻
systemctl stop firewalld
systemctl disable firewalld
三、安裝Cobbler
1.安裝最新的epel庫
rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm
rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
2.安裝Cobbler以及相關的包
yum install cobbler cobbler-web pykickstart xinetd dhcp dnsmasq syslinux -y
yum install cobbler cobbler-web pykickstart xinetd dhcp httpd tftp -y
3.啟動Cobbler及其他服務
systemctl enable cobblerd
systemctl start cobblerd
systemctl enable httpd
systemctl start httpd
systemctl enable xinetd
systemctl start xinetd
Cobbler-Web提供了一個網站管理服務，默認用戶名和密碼都是"cobbler",Web瀏覽地址可以通過以下鏈接： https://172.18.50.30/cobbler_web //注意是https
四、配置Cobbler
1、設置文件里的default_password_crypted控制在kickstart過程中的新系統的超級用戶口令
openssl passwd -1
生成系統的root用戶密碼
$1$Ve0a/FjX$GmL.ZpJYdvFPoYdpT1Zqb1
2、修改/etc/cobbler/settings配置
vim /etc/cobbler/settings
default_password_crypted: "$1$Ve0a/FjX$GmL.ZpJYdvFPoYdpT1Zqb1"
manage_dhcp: 1
manage_dns: 1
next_server: 172.168.50.30（主機名）
pxe_just_once: 1
server: 172.168.50.30（主機名）
3、修改/etc/xinetd.d/tftp配置
vim /etc/xinetd.d/tftp
disable = no
4、修改/etc/cobbler/dhcp.template配置
subnet 172.18.50.0 netmask 255.255.255.0 {
option routers 172.18.50.254; #網關
option domain-name-servers 61.139.2.69; #DNS
option subnet-mask 255.255.255.0; #子網掩碼
range dynamic-bootp 172.18.50.35 172.18.50.39; #ip范圍
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
class "pxeclients" {
match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
if option pxe-system-type = 00:02 {
filename "ia64/elilo.efi";
} else if option pxe-system-type = 00:06 {
filename "grub/grub-x86.efi";
} else if option pxe-system-type = 00:07 {
filename "grub/grub-x86_64.efi";
} else {
filename "pxelinux.0";
}
}
}
5、修改/etc/cobbler/dnsmasq.template配置一個簡單的DHCP server
vim /etc/cobbler/dnsmasq.template
...
...
read-ethers
addn-hosts = /var/lib/cobbler/cobbler_hosts
dhcp-range=172.18.50.35,172.18.50.39
dhcp-option=3,$next_server
dhcp-lease-max=1000
dhcp-authoritative
dhcp-boot=pxelinux.0
dhcp-boot=net:normalarch,pxelinux.0
dhcp-boot=net:ia64,$elilo
$insert_cobbler_system_definitions
6、檢查及同步Cobbler
systemctl restart cobblerd
cobbler check (這個命令幫助檢測Cobbler配置目前仍然存在的問題，根據提示修改這些問題，然后重啟cobbler即可)
注：這里cobbler check 遇到的有:
1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
https://github.com/cobbler/cobbler/wiki/Selinux
2 : named is not installed and/or in path
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 : enable and start rsyncd.service with systemctl
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
解決：
1、關閉selinux，前面已經改過，先忽略
2、yum install bind -y
3、cobbler get-loaders
4、systemctl enable rsyncd
systemctl start rsyncd
5、rpm -Uvh ftp://rpmfind.net/linux/epel/6/x86_64/debmirror-2.14-2.el6.noarch.rpm --nodeps --force
修改debmirror配置/etc/debmirror.conf
vim /etc/debmirror.conf
#@dists="sid"; #注釋
#@arches="i386"; #注釋
6、yum install fence-agents -y
systemctl restart cobblerd
cobbler sync
五、導入Distribution
mkdir /mnt/iso
mount -o loop /dev/cdrom /mnt/iso #也可以掛載iso文件
cobbler import --arch=x86_64 --path=/mnt/iso --name=CentOS-7
cobbler distro list
cobbler profile list
cobbler distro report --name=CentOS-7-x86_64 #顯示詳細信息
六、刪除導入的系統
cobbler profile find --distro=CentOS-7-x86_64 #查看配置是否存在
cobbler profile remove --name=CentOS-7-x86_64 #刪除配置文件
cobbler distro remove --name=CentOS-7-x86_64 #刪除distro
cobbler profile find --distro=CentOS-7-x86_64 #再查看配置已無
