#cobbler-web web管理

#pykickstart KS文件检查

#xinetd 守护进程

systemctl start cobblerd && systemctl enable cobblerd
systemctl start httpd && systemctl enable httpd
systemctl start xinetd && systemctl enable xinetd

/etc/cobbler/settings中几个比较重要的参数设置(根据需求设置)

manage_dhcp：1
manage_dns：1
manage_tftpd：1
restart_dhcp：1
restart_dns：1
pxe_just_once：1                 #防止安装循环配置始终从网络引导，激活此选项时机器告诉 Cobbler 安装已完成。Cobbler 将系统对象的 netboot 标志更改为 false，这会强制机器从本地磁盘引导
next_server：<服务器的 IP 地址>   #用在 DHCP 配置文件中，向机器告知提供引导文件的服务器地址
server：<服务器的 IP 地址>        #用于引用 Cobbler 服务器地址

　　

初始化cobbler

systemctl restart cobblerd
cobbler check  #检查初始化配置按提示配置即可
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 : enable and start rsyncd.service with systemctl
6 : debmirror package is not installed, it will be required to manage debian deployments and repositories
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

　　

获取启动文件

cobbler get-loaders   #下载有点慢

　　

开启TFTP服务

vim /etc/xinetd.d/tftp
        disable                 = no
systemctl restart xinetd

　　

开启rsyncd服务

systemctl start rsyncd && systemctl enable rsyncd

设置默认root密码

openssl passwd -1 -salt 'root' 'root'   #密码明文为root
$1$root$9gr5KxwuEdiI80GtIzd.U0
vim /etc/cobbler/settings
101 default_password_crypted: "$1$root$9gr5KxwuEdiI80GtIzd.U0"　

cobbler管理DHCP

vim /etc/cobbler/dhcp.template #重启cobbler后，cobbler会生成一个模板文件
subnet 192.168.100.0 netmask 255.255.255.0 {
     option routers             192.168.100.1;
     option domain-name-servers 192.168.100.1;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.100.50 192.168.100.100;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

　　

生成新的配置文件

[root@linux-node1 ~]# systemctl restart cobblerd
[root@linux-node1 ~]# cobbler sync

　　

导入镜像

mount /dev/cdrom /mnt #在光驱中加载一个完成的centos7 ISO文件
mount: /dev/sr0 is write-protected, mounting read-only
cobbler import --path=/mnt/ --name=/CentOS-7-x86_64 --arch=x86_64 #使用import导入
cobbler profile list #查看镜像目录
   CentOS-7-x86_64
cobbler profile report #查看cobbler系统仓库中的版本信息
Name                           : CentOS-7-x86_64
TFTP Boot Files                : {}
Comment                        :
DHCP Tag                       : default
Distribution                   : CentOS-7-x86_64 #版本名称
Enable gPXE?                   : 0
Enable PXE Menu?               : 1
Fetchable Files                : {}
Kernel Options                 : {} #自定义内核参数
Kernel Options (Post Install)  : {}
Kickstart                      : /var/lib/cobbler/kickstarts/sample_end.ks #这里显示此系统版本使用的是系统自带的kickstart文件

　　

制作ks文件

kickstart文件的制作非常简单。

首先安装system-config-kickstart。

yum install system-config-kickstart
system-config-kickstart  #要有桌面环境

修改默认ks文件执行system-config-kickstart启用图形界面进行配置（使用xmanager之类的连接程序）

cd /var/lib/cobbler/kickstarts/
上传自定义ks文件 CentOS-7-x86_64.cfg
cobbler profile edit --name=CentOS-7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-7-x86_64.cfg #上传完成后修改成我们自己的ks文件
cobbler profile edit --name=CentOS-7-x86_64 --kopts='net.ifnames=0 biosdevname=0' #这里我们顺便修改一下内核文件参数，让centos7初始化网卡名为“eth”
cobbler sync   #更改配置后都要执行
