cobbler无人值守安装
环境
[root@localhost ~]# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core)
[root@localhost ~]# systemctl stopt firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# hostname -I
::1 127.0.0.1
安装cobbler
yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django
[root@localhost ~]# cobbler check
cobblerd does not appear to be running/accessible: error(111, 'Connection refused')
解决办法
[root@ localhost ~]# systemctl start httpd
[root@ localhost ~]# systemctl start cobblerd
继续执行cobbler会出现
[root@ localhost ~]# 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 otherthan 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' todownload 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 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
7 : ksvalidator was not found, install pykickstart
8 : 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
9 : 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.

配置dhcp
修改cobbler的dhcp配置模板
不要修改本身dhcp配置文件，cobbler会覆盖掉
[root@ localhost ~]# vim /etc/cobbler/dhcp.template：
subnet 10.0.0.41 netmask 255.255.255.0 {
option routers 10.0.0.5;
option domain-name-servers 10.0.0.1;
option subnet-mask 255.255.255.0;
range dynamic-bootp 10.0.0.100 10.0.0.254;
[root@ localhost ~]# sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings --是用cobbler管理dhcp的

需要一台centos系统（但是不需要选择镜像）
内存需要2GB 内存过小导致无法操作
耐心等待安装出现下图就表示已经安装成功了
