一、cobbler安装部署
1、修改YUM仓库
vim /etc/yum.repos.d/my.repo
[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/
enabled=1
gpgcheck=0
2、安装cobbler
yum install dhcp httpd xinetd tftp cobbler cobbler-web -y
3、修改cobbler配置文件
生成加密密码：openssl passwd -1 -salt bw.com 123456
vim /etc/cobbler/settings
server: 192.168.100.100
next_server: 192.168.100.100
default_password_crypted: "$1$stu.com$Pp0HQwZhSF...mXIxjJAH." #root管理员密码
4、配置DHCP
vim /etc/dhcpd/dhcp.conf
option domain-name "stu.com";
option domain-name-servers 192.168.100.100;
default-lease-time 36000;
max-lease-time 72000;
log-facility local7;
subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.110 192.168.100.150;
option routers 192.168.100.1;
option broadcast-address 192.168.100.255;
next-server 192.168.100.100;
filename "pxelinux.0";
}
systemctl start dhcpd
systemctl enable dhcpd
5、配置tftp
vim /etc/xinetd.d/tftp
disable= no
systemctl start xinetd
systemctl enable xinetd
6、下载启动引导文件
systemctl start httpd
systemctl enable httpd
cobbler get-loaders
centos7.5+cobbler2.8.4实战图文攻略--2019持续更新
cobbler sync
7、导入光盘镜像文件
cobbler import --path=/mnt/cdrom --name=c75 --arch=x86_64
centos7.5+cobbler2.8.4实战图文攻略--2019持续更新
8、生成自动应答文件
vim /var/lib/cobbler/kickstarts/c75.ks
#platform=x86, AMD64, Intel EM64T
#version=DEVEL
#Install OS instead of upgrade
install
#Keyboard layouts
keyboard 'us'
#Root password
rootpw --iscrypted $default_password_crypted #见第3步
#System timezone
timezone Asia/Shanghai
#Use network installation
url --url=$tree
#System language
lang en_US.UTF-8
#Firewall configuration
firewall --disabled
#System authorization information
auth --useshadow --enablemd5
#Use graphical install
text
firstboot --disable
#SELinux configuration
selinux --disabled
#Reboot after installation
reboot
#System bootloader configuration
bootloader --location=mbr
#Clear the Master Boot Record
zerombr
#Partition clearing information
clearpart --all --initlabel
#Disk partitioning information
part /boot --fstype="xfs" --size=256
part swap --fstype="swap" --size=1024
part / --fstype="xfs" --ondisk=sda --size=1 --grow #使用全部剩余空间
#Network information
$SNIPPET('network_config')
%pre
$SNIPPET('log_ks_pre')
$SNIPPET('kickstart_start')
$SNIPPET('pre_install_network_config')
#Enable installation monitoring
$SNIPPET('pre_anamon')
%end
%packagesbr/>@^minimalbr/>@compat-librariesbr/>@core
@development
bash-completion
vim
net-tools

tree
lrzsz
wget
telnet
-postfix
%end
%addon com_redhat_kdump --disable --reserve-mb='auto'
%end
%post
#Start yum configuration
$yum_config_stanza
#End yum configuration
%end
%post
sed -i "1s/5/0/" /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
rm -f /etc/yum.repos.d/CentOS*
yum remove NetworkManager -y
%end
二、cobbler配置
1、编辑profile
cobbler profile edit --name=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75.ks
cobbler profile edit --name=c75-x86_64 --kopts='net.ifnames=0 biosdevname=0 ipv6.disable=1'
2、客户端默认local启动
vim /etc/cobbler/pxe/pxedefault.template
DEFAULT menu
PROMPT 0
MENU TITLE Cobbler | http://cobbler.github.io/
TIMEOUT 1
TOTALTIMEOUT 6000
ONTIMEOUT $pxe_timeout_profile
LABEL local
MENU LABEL (local)
MENU DEFAULT
LOCALBOOT -1
$pxe_menu_items
MENU end
cobbler system add --name=default --profile=c75-x86_64
cobbler sync
systemctl restart dhcpd
systemctl restart xinetd
systemctl restart httpd
systemctl restart cobblerd
3、配置IP信息及主机名
cobbler system add --name=lbmaster --profile=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75.ks \
--interface=eth0 --static=1 --mac=00:50:56:20:38:C8 --ip-address=192.168.100.10 --subnet=255.255.255.0 --gateway=192.168.100.1 \
--name-servers="192.168.100.100" --hostname=lbmaster.stu.com
4、配置YUM仓库
（1）同步网络YUM仓库
cobbler repo add --name=openstack --mirror=https://mirrors.aliyun.com/centos/7.5.1804/cloud/x86_64/openstack-ocata/ --arch=x86_64 --breed=yum
cobbler repo add --name=zabbix --mirror=https://mirrors.aliyun.com/zabbix/zabbix/3.5/rhel/7/x86_64/ --arch=x86_64 --breed=yum
cobbler reposync
cobbler profile edit --name=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75-cobbler.ks --repos="openstack"
crontab -e
cobbler reposync --tries=3 --no-fail
（2）修改默认YUM仓库配置文件
vim /var/www/cobbler/ks_mirror/config/c75-x86_64.repo
[core-0]br/>name=core-0br/>baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64
enabled=1
gpgcheck=0
priority=$yum_distro_priority
[epel]
names=epel
baseurl=https://mirrors.aliyun.com/epel/7Server/x86_64/
enabled=1
gpgcheck=0
systemctl start cobblerd
systemctl enable cobblerd
cobbler sync
