cobbler系统自动化安装
准备环境：
centos7
EPEL源(sohu旧源)
连接互联网
独立网段vmnet6 （确保vmware中dhcp服务关闭）
eth0:10.0.0.200/16 vmnet6
eth1:172.20.0.7/16 vmnet0 桥接 192.168.33.131 NAT 可以上网
[root@centos7 ~]#getenforce //确保selinux已经关闭 Disabled [root@centos7 ~]#iptables -F //清防火墙
1、 安装包 [root@centos7 ~]#yum install cobbler cobbler-web dhcp [root@centos7 ~]#systemctl enable dhcpd httpd tftp cobblerd //暂且先不起dhcp, 服务尚未配置 [root@centos7 ~]#systemctl start cobblerd httpd tftp
2、检查cobbler配置存在的问题,逐一解决 [root@centos7 ~]#cobbler check
3、编辑cobbler的配置文件 [root@centos7 ~]#vim /etc/cobbler/settings server 10.0.0.200 next_server: 10.0.0.200 manage_dhcp: 1 default_password_crypted: "$1$iXvBL83y$EYkqMm9z.clIubP/kB6PC0" //用下面命令生成密码来取代默认的密码，更安全
[root@centos7 ~]#openssl passwd -1 //生成root口令 Password: Verifying - Password: $1$iXvBL83y$EYkqMm9z.clIubP/kB6PC0
执行 cobbler get-loaders 命令即可；否则，需要安装syslinux程序包，而后复制/usr/share/syslinux/{pxelinux.0,memu.c32}等文件至/var/lib/cobbler/loaders/目录中； [root@centos7 ~]#cobbler get-loaders task started: 2019-01-31_100341_get_loaders task started (id=Download Bootloader Content, time=Thu Jan 31 10:03:41 2019) downloading https://cobbler.github.io/loaders/README to /var/lib/cobbler/loaders/README downloading https://cobbler.github.io/loaders/COPYING.elilo to /var/lib/cobbler/loaders/COPYING.elilo downloading https://cobbler.github.io/loaders/COPYING.yaboot to /var/lib/cobbler/loaders/COPYING.yaboot downloading https://cobbler.github.io/loaders/COPYING.syslinux to /var/lib/cobbler/loaders/COPYING.syslinux downloading https://cobbler.github.io/loaders/elilo-3.8-ia64.efi to /var/lib/cobbler/loaders/elilo-ia64.efi downloading https://cobbler.github.io/loaders/yaboot-1.3.17 to /var/lib/cobbler/loaders/yaboot downloading https://cobbler.github.io/loaders/pxelinux.0-3.86 to /var/lib/cobbler/loaders/pxelinux.0 downloading https://cobbler.github.io/loaders/menu.c32-3.86 to /var/lib/cobbler/loaders/menu.c32 downloading https://cobbler.github.io/loaders/grub-0.97-x86.efi to /var/lib/cobbler/loaders/grub-x86.efi downloading https://cobbler.github.io/loaders/grub-0.97-x86_64.efi to /var/lib/cobbler/loaders/grub-x86_64.efi *** TASK COMPLETE ***
//查看/var/lib/cobbler/loaders/目录结构 [root@centos7 ~]#tree /var/lib/cobbler/loaders/ /var/lib/cobbler/loaders/ ├── COPYING.elilo ├── COPYING.syslinux ├── COPYING.yaboot ├── elilo-ia64.efi ├── grub-x86_64.efi ├── grub-x86.efi ├── menu.c32 ├── pxelinux.0 ├── README └── yaboot
//查看/var/lib/tftpboot/目录结构 [root@centos7 ~]#tree /var/lib/tftpboot/ /var/lib/tftpboot/ ├── boot │ └── grub │ └── menu.lst ├── etc ├── grub │ ├── efidefault │ └── images -> ../images ├── images ├── images2 ├── memdisk ├── menu.c32 ├── ppc ├── pxelinux.0 ├── pxelinux.cfg │ └── default └── s390x └── profile_list
4、修改cobbler的dhcp模版，这个模板会覆盖dhcp本身的配置文件 [root@centos7 ~]#vim /etc/cobbler/dhcp.template subnet 10.0.0.0 netmask 255.255.0.0 { option routers 10.0.0.254; option domain-name-servers 223.5.5.5; range dynamic-bootp 10.0.0.10 10.0.100.254;
**5、同步cobbler的配置，可以看到同步干了哪些事 ** [root@centos7 ~]#cobbler sync
[root@cobbler ~]# cobbler //Cobbler的命令行管理（6和7的命令是一致的） usage
cobbler <distro|profile|system|repo|p_w_picpath|mgmtclass|package|file> ... [add|edit|copy|getks*|list|remove|rename|report] [options|--help] cobbler <aclsetup|buildiso|import|list|replicate|report|reposync|sync|validateks|version|signature|get-loaders|hardlink> [options|--help] cobbler check //核对当前设置是否有问题 cobbler list //列出所有的cobbler元素cobbler report //列出元素的详细信息 cobbler sync //同步配置到数据目录,更改配置最好都要执行下 cobbler reposync //同步yum仓库 cobbler distro //查看导入的发行版系统信息 cobbler system //查看添加的系统信息cobbler profile //查看配置信息
6、导入系统源 [root@centos7 ~]#echo "- - -" > /sys/class/scsi_host/host0/scan //添加光驱，挂载光盘，通过下面步骤识别光盘
[root@centos7 ~]#df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sr0 9176232 9176232 0 100% /run/media/root/CentOS 7 x86_64 /dev/sr1 3897932 3897932 0 100% /run/media/root/CentOS_6.10_Final
[root@centos7 ~]#mount /dev/sr1 /mnt/ //临时挂载光盘
[root@centos7 mnt]# cobbler import --name=centos-6.10-x86_64 --path=/mnt --arch=x86_64 --name //为安装源定义一个名字 --path //镜像路径 --arch //指定安装源是32位、64位、ia64, 目前支持的选项有: x86 x86_64 ia64
#查看镜像列表 [root@centos7 mnt]# cobbler distro list CentOS-6.10-x86_64
[root@centos7 ~]#du -sh /var/www/cobbler/ks_mirror/ //导入文件的路径 3.8G /var/www/cobbler/ks_mirror/
[root@centos7 ~]#cat /var/lib/tftpboot/pxelinux.cfg/default DEFAULT menu PROMPT 0 MENU TITLE Cobbler | http://cobbler.github.io/ TIMEOUT 200 TOTALTIMEOUT 6000 ONTIMEOUT local
LABEL local MENU LABEL (local) MENU DEFAULT LOCALBOOT -1
LABEL centos-6.10-x86_64 kernel /images/centos-6.10-x86_64/vmlinuz MENU LABEL centos-6.10-x86_64 append initrd=/images/centos-6.10-x86_64/initrd.img ksdevice=bootif lang= kssendmac text ks=http://10.0.0.200/cblr/svc/op/ks/profile/centos-6.10-x86_64 ipappend 2 MENU end
7、 导入自定义的ks文件 [root@centos7 ~]#cobbler profile remove --name=centos-7.6-x86_64 [root@centos7 ~]#cobbler profile add --name=centos-7.6-x86_64_test --distro=centos-7.6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7_mini.cfg
