cobbler自动安装centos｛7，8｝

1,安装cobbler以及相关服务，安装cobbler需要epel源

[root@localhost yum.repos.d]#yum install cobbler dhcp -y
[root@localhost yum.repos.d]#systemctl enable --now cobblerd httpd tftp dhcpd
[root@localhost yum.repos.d]# cat /etc/yum.repos.d/tence.repo 
[tt]
name=11
baseurl=https://mirrors.cloud.tencent.com/epel/7/x86_64/
enabled=1
gpgcheck=0

2，修改配置

[root@localhost yum.repos.d]#openssl passwd -1 '123' #生成加密密码
$1$1spuisnh$j34LNmyTQWs3l6xKxCZY60

#根据以上提示，只需要做1，2，8这三项即可，修改下面四行
[root@localhost yum.repos.d]#vim /etc/cobbler/settings
default_password_crypted: "$1$1spuisnh$j34LNmyTQWs3l6xKxCZY60"
next_server：< tftp服务器的 IP 地址> #本机
server：<cobbler服务器的 IP 地址> #本机
manage_dhcp：1 #设置为1，表示通过cobbler生成dhcpd.conf配置文件

3，修改DHCP模板文件

#修改dhcp的模版文件下面的行，用来生成dhcp的配置文件
[root@localhost yum.repos.d]#vim /etc/cobbler/dhcp.template
#你的网段
subnet 192.168.100.0 netmask 255.255.255.0 {  
#网关
option routers 192.168.100.1;
#域名服务器
option domain-name-servers 180.76.76.76,223.6.6.6;
#掩码
option subnet-mask 255.255.255.0;
#分配网段
range dynamic-bootp 192.168.100.1 192.168.100.200;

[root@localhost yum.repos.d]#cobbler sync
[root@localhost yum.repos.d]#systemctl start dhcpd #可查看dhcp配置文件验证

4，下载启动文件

[root@localhost yum.repos.d]# cobbler get-loaders --force 
task started: 2021-05-20_234359_get_loaders
task started (id=Download Bootloader Content, time=Thu May 20 23:43:59 2021)
downloading https://cobbler.github.io/loaders/README to /var/lib/cobbler/loaders/README

#报错，执行下列操作
#网上查的依然报错
[root@localhost yum.repos.d]# cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/
[root@localhost yum.repos.d]#  cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
[root@localhost yum.repos.d]# systemctl restart cobblerd
[root@localhost yum.repos.d]# cobbler check #没办法做check 根据报错提示安装了以下包

[root@localhost yum.repos.d]# yum install -y rsync；systemctl enable --now rsyncd
[root@localhost yum.repos.d]#yum install -y fence-agents
[root@localhost yum.repos.d]# yum install -y debmirror
[root@localhost ~]# vim /etc/debmirror.conf #注释了一些信息
#@dists="sid";
@sections="main,main/debian-installer,contrib,non-free";
#@arches="i386";
#下是报错提示
The following are potential configuration items that you may want to fix:

1 : 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.
2 : comment out 'dists' on /etc/debmirror.conf for proper debian support
3 : comment out 'arches' on /etc/debmirror.conf for proper debian support
#做完上述操作后
[root@localhost ~]#systemctl restart cobblerd
[root@localhost ~]#scobbler get-loaders 
[root@localhost yum.repos.d]#  cobbler get-loaders

5，同步后查看启动文件是否完整

[root@centos7 ~]#cobbler sync
[root@localhost yum.repos.d]# tree /var/lib/tftpboot/
/var/lib/tftpboot/
├── boot
│   └── grub
│       └── menu.lst

10 directories, 10 files

6,修改模板信息

[root@localhost yum.repos.d]# vim /etc/cobbler/pxe/pxedefault.template
MENU TITLE Cobbler | http://123.com/
[root@localhost yum.repos.d]# cobbler sync

7,导入CentOS系统的安装文件，生成相应的YUM源

[root@localhost yum.repos.d]# mount /dev/sr0 /mnt/c7/
mount: /dev/sr0 is write-protected, mounting read-only
[root@localhost yum.repos.d]# mount /dev/sr1 /mnt/c8/
mount: /dev/sr1 is write-protected, mounting read-only
[root@localhost yum.repos.d]# ll !$
ll /mnt/c8/

#生成cobbler镜像 
[root@localhost yum.repos.d]# cobbler import --name=centos-8.1-x86_64 --path=/mnt/c8/ --arch=x86_64 #centos7，8大概需要十多个g注意保持磁盘空间充裕
[root@localhost yum.repos.d]#  cobbler import --name=centos-7.7-x86_64 --path=/mnt/c7/ -- arch=x86_64 #结尾*** TASK COMPLETE ***

8，准备 kickstart文件,并关联至指定的YUM源，kickstart的文件建议用生成之前的镜像安装后的anaconda-ks.cfg 不然可能会报错，这里只准备centos7,url配置：url --url=$tree

root@localhost ~]# vim /var/lib/cobbler/kickstarts/centos7.cfg

[root@localhost ~]# cobbler profile remove --name=centos-8.1-x86_64
[root@localhost ~]# cobbler profile list
   CentOS-7.1_test
   CentOS-8.1_test

9，同步，重启，查看报告

[root@localhost ~]# cobbler sync
[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# cobbler report

10,测试
