1.cobbler服务端部署
1.1安装Cobbler及相关软件包
注：必须使用CentOS官方源
#安装epel
[root@localhost ~]# yum install epel-release rsync rsync-daemon -y
#
[root@localhost ~]# yum module list | grep cobbler
cobbler 3 default [d] Versa
tile Linux deployment server
cobbler 3.3 default Versa
tile Linux deployment server
#cobbler直接开启会失败因为有两个 指定cobbler：3 开启
[root@localhost ~]# dnf module enable cobbler:3 -y
#此时查看已经有了cobbler可以通过yum安装了
[root@localhost ~]# yum list all | grep cobbler
cobbler.noarch 3.2.2-11.module_el8+14161+f12890f2 epel-modular
cobbler-tests.noarch 3.2.2-11.module_el8+14161+f12890f2 epel-modular
cobbler-web.noarch 3.2.2-11.module_el8+14161+f12890f2 epel-modular
[root@localhost ~]# yum install httpd dhcp* tftp tftp-server cobbler cobbler-web pykickstart -y
1.2配置服务
#开启httpd和cobbler
[root@localhost ~]# systemctl enable --now httpd
[root@localhost ~]# systemctl enable --now cobblerd
[root@localhost ~]# systemctl enable --now rsyncd
[root@localhost ~]# systemctl enable --now tftp
#关闭防火墙和selinux
[root@localhost ~]# setenforce 0
[root@localhost ~]# getenforce
Permissive
[root@localhost ~]# grep 'SELINUX=disabled' /etc/selinux/config
SELINUX=disabled
1.3配置Cobbler
[root@localhost ~]# sed -i 's/^server: 127.0.0.1/server: 192.168.220.5/' /etc/cobbler/settings.yaml
[root@localhost ~]# grep "^server: " /etc/cobbler/settings.yaml
server: 192.168.220.5 //此处修改为本机ip
[root@localhost ~]# sed -i "s#next_server: 127.0.0.1#next_server: 192.168.220.5#" /etc/cobbler/settings.yaml
[root@localhost ~]# grep "^next_server: " /etc/cobbler/settings.yaml
next_server: 192.168.220.5 //此处修改为本机ip
#生成密码
[root@localhost ~]# openssl passwd -1 -salt "$RANDOM" '123456789'
$1$20982$uHkwNZPwK6e4cbNUT8uZR0
# 修改 /etc/cobbler/settings 文件中的 default_password_crypted 参数的值为上面生成的密码串
[root@localhost ~]# grep 'default_password_crypted:' /etc/cobbler/settings.yaml
default_password_crypted: "$1$20982$uHkwNZPwK6e4cbNUT8uZR0" //此处修改为生成的密码
#dhcp功能打开
[root@localhost ~]# sed -i "s#manage_dhcp: false#manage_dhcp: true#" /etc/cobbler/settings.yaml
[root@localhost ~]# grep 'manage_dhcp:' /etc/cobbler/settings.yaml
manage_dhcp: true
# 核对当前设置是否有问题
[root@localhost ~]# cobbler check
The following are potential configuration items that you may want to fix:
1: some network boot-loaders are missing from /var/lib/cobbler/loaders. 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, and yaboot.
2: reposync is not installed, install yum-utils or dnf-plugins-core
3: yumdownloader is not installed, install yum-utils or dnf-plugins-core
4: debmirror package is not installed, it will be required to manage debian deployments and repositories
5: 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.
# 问题2和问题3：
[root@localhost ~]# yum install yum-utils -y
# 问题4和问题5可以忽略
#因为是debian系统才需要解决显示使用的是CentOS8
#debian系统解决办法安装 fence-agents
#问题1：
[root@localhost ~]# yum install syslinux* -y
[root@localhost ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
[root@localhost ~]# cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/
[root@localhost ~]# ls /var/lib/cobbler/loaders/
menu.c32 pxelinux.0
1.4配置DHCP模板文件
[root@localhost ~]# vim /etc/cobbler/dhcp.template //列出修改过的相关字段
subnet 192.168.220.0 netmask 255.255.255.0 { //网段
option routers 192.168.220.2; //网关
option domain-name-servers 114.114.114.114; //dns
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.220.200 192.168.220.210; //地址池
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
1.5同步Cobbler配置

*** TASK COMPLETE ***
# 重启所有相关服务
[root@localhost ~]# systemctl restart httpd cobblerd rsyncd dhcpd
2.安装系统
2.1手动安装
注：内存必须为2G以上
新建一个不带镜像的虚拟机 然后启动
#此时使用新虚拟机去安装系统并不会成功 需要做如下操作
[root@localhost ~]# ls /usr/share/cobbler/bin/
migrate-data-v2-to-v3.py mkgrub.sh
migrate-settings.sh settings-migration-v1-to-v2.sh
[root@localhost ~]# bash /usr/share/cobbler/bin/mkgrub.sh //执行时会有报错 但不影响
[root@localhost ~]# ll /var/lib/cobbler/loaders/ //此时此目录会新增两个文件
总用量 72
drwxr-xr-x 2 root root 79 8月 12 05:53 grub //新增文件 开机会需要
lrwxrwxrwx 1 root root 31 8月 12 05:53 ldlinux.c32 -> /usr/share/syslinux/ldlinux.c32 //新增文件
-rw-r--r-- 1 root root 26272 8月 12 04:33 menu.c32
-rw-r--r-- 1 root root 42376 8月 12 04:32 pxelinux.0
[root@localhost ~]# cobbler sync //因为文件做出改变 所以需要同步下
再次启动就会跳转到这个界面选择Centos-8-x86_64回车，然后等待一段时间
注：安装过程需要一段时间
此项需要手动选择
看到这样的 就是正在安装软件包
等待安装结束后就可以看到正常虚拟机的启动过程
用户为root密码为之前生成的密码
2.2自动安装
使用https访问到cobbler的网页
账号密码都为cobbler
创建系统
生成mac地址
创建虚拟机时生成mac地址
其他未选项默认即可
点击sace保存
保存完成后会生成一个系统
同步
同步完成后右上角会显示同步日志点击就可以查看
同步日志
启动新创建的虚拟机（生成mac在网页绑定的那台）
会自动选择不需要要手动操作
等待安装结束后
用户root密码和之前的一样
网卡是指定的eth0
ip也是指定的192.168.220.200
