系统环境配置,软件包安装 centos7
yum update -y
sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/sysconfig/selinux
# the file in some versions of the system are in /etc/selinux/config
setenforce 0
service iptables stop #or systemctl stop firewalld
hostnamectl set-hostname cobbler
echo "cobbler 192.168.10.250" >>/etc/hosts
yum install -y chrony.x86_64 && systemctl start chronyd && systemctl enable chronyd
timedatectl set-ntp 0
timedatectl set-timezone Asia/Shanghai
yum install bash-completion epel-release.noarch -y
yum makecache
reboot
service install
服务安装,启动
yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web
systemctl start cobblerd
systemctl enable cobblerd
systemctl start httpd
systemctl enable httpd
systemctl start rsyncd
systemctl enable rsyncd
cobbler check
[root@cobbler ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it.
2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network.
3 : change 'disable' to 'no' in /etc/xinetd.d/tftp
4 : 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.
5 : debmirror package is not installed, it will be required to manage debian deployments and repositories
6 : ksvalidator was not found, install pykickstart
7 : 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
8 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
Restart cobblerd and then run 'cobbler sync' to apply changes.
- 根据提示1.2,修改serverip为内网IP
sed -i 's/^server: 127.0.0.1/server: 192.168.10.250/' /etc/cobbler/settings
sed -i 's/^next_server: 127.0.0.1/next_server: 192.168.10.250/' /etc/cobbler/settings
- 修改3,tftp配置
vi /etc/xinetd.d/tftp
disable = no
- 下载4,cobbler-loaders
cobbler get-loaders
- 安装6.8,pykickstart
yum install -y pykickstart fence-agents
- 设置7,默认密码加密方式和默认密码加入配置文件
openssl passwd -1 -salt "abcdef" "1234567890"
$1$abcdef$MgVBnksOqk99cgXuJlRJS0
vi /etc/cobbler/settings
default_password_crypted $1$abcdef$MgVBnksOqk99cgXuJlRJS0
此时重启服务器.让修改都生效第5项是deb的包管理工具.我用的centos7所以不管
manage dhcp
- 启用dhcp功能
cat /etc/cobbler/settings|grep manage
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings
- 修改 dhcp 配置
vi /etc/cobbler/dhcp.template
subnet 192.168.10.0 netmask 255.255.255.0 {
option routers 192.168.10.1;
option domain-name-servers 192.168.10.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.10.120 192.168.10.199;
systemctl restart cobblerd.service
cobbler sync
cat /etc/dhcp/dhcpd.conf #检查dhcp配置是否正确
systemctl start dhcpd
systemctl enable dhcpd

distro,profile管理
cobbler distro copy --name xxx --newname yyy
cobbler profile copy --name xxx --newname yyy
其它add copy edit 同理.看看help
kickstart配置
yum install system-config-kickstart -y
system-config-kickstart #安装x11可以图形化设置生成ks文件
cobbler-web
htdigest /etc/cobbler/users.digest "Cobbler" cobbler #改密码
htdigest /etc/cobbler/users.digest "Cobbler" sylar #新建用户
https://192.168.10.250/cobbler_web #注意必须使用https
cobbler-dhcp冲突
如果在一个局域网中有多个dhcp服务器的,开启cobbler上的dhcp服务会干扰目前正在运行的dhcp服务器的话,只需把cobbler上的dhcp的range网络段给注释掉即可,就是变成只能指定分配ip.同时使用不同的网段
cobbler system add --name=network --ip=172.16.0.0/16 --profile=net-x86_64
