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
cobbler sync
7、导入光盘镜像文件
cobbler import --path=/mnt/cdrom --name=c75 --arch=x86_64
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
%packages @^minimal @compat-libraries @core @development bash-completion vim net-tools bind-utils 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
$pxe_menu_items
MENU end
cobbler system add --name=default --profile=c75-x86_64
cobbler sync
systemctl restart dhcpd systemctl restart xinetd systemctl restart httpd systemctl restart cobblerd
3、配置IP信息及主机名
cobbler system add --name=lbmaster --profile=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75.ks
--interface=eth0 --static=1 --mac=00:50:56:20:38:C8 --ip-address=192.168.100.10 --subnet=255.255.255.0 --gateway=192.168.100.1
--name-servers="192.168.100.100" --hostname=lbmaster.stu.com
4、配置YUM仓库
(1)同步网络YUM仓库 cobbler repo add --name=openstack --mirror=https://mirrors.aliyun.com/centos/7.5.1804/cloud/x86_64/openstack-ocata/ --arch=x86_64 --breed=yum cobbler repo add --name=zabbix --mirror=https://mirrors.aliyun.com/zabbix/zabbix/3.5/rhel/7/x86_64/ --arch=x86_64 --breed=yum
cobbler reposync
cobbler profile edit --name=c75-x86_64 --kickstart=/var/lib/cobbler/kickstarts/c75-cobbler.ks --repos="openstack" crontab -e cobbler reposync --tries=3 --no-fail
(2)修改默认YUM仓库配置文件
vim /var/www/cobbler/ks_mirror/config/c75-x86_64.repo
[core-0] name=core-0 baseurl=http://@@http_server@@/cobbler/ks_mirror/c75-x86_64 enabled=1 gpgcheck=0 priority=$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
