管理distro安装一个空壳centos8的虚拟机,不需要给镜像
进来后就发现可以自动获取ip选择我们刚才上传的镜像

正在安装包

安装完成,登录查看ip


cobbler部署

Please review the following wiki page for details on ensuring Cobbler works correctly in your SELinux environment:     https://github.com/cobbler/cobbler/wiki/Selinux 2: 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. 3: reposync is not installed, install yum-utils or dnf-plugins-core 4: yumdownloader is not installed, install yum-utils or dnf-plugins-core 5: debmirror package is not installed, it will be required to manage debian deployments and repositories 6: 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1解决办法: [root@localhost ~]# yum -y install syslinux* [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  #问题2和问题三的解决办法: [root@localhost ~]# yum -y install yum-utils  #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  #配置DHCP模板文件 [root@localhost ~]# vim /etc/cobbler/dhcp.template  23 subnet 192.168.111.0 netmask 255.255.255.0 {  24      option routers             192.168.111.255;  25      option domain-name-servers 8.8.8.8;  26      option subnet-mask         255.255.255.0;  27      range dynamic-bootp        192.168.111.100 192.168.111.110;  28      default-lease-time         21600;  29      max-lease-time             43200;  30      next-server                $next_server;  #同步cobbler配置 [root@localhost ~]# systemctl restart httpd cobblerd [root@localhost ~]# cobbler sync task started: 2022-09-24_163754_sync task started (id=Sync, time=Sat Sep 24 16:37:54 2022) running python triggers from /var/lib/cobbler/triggers/task/sync/pre/* running shell triggers from /var/lib/cobbler/triggers/task/sync/pre/* shell triggers finished successfully running pre-sync triggers cleaning trees removing: /var/lib/tftpboot/grub/system removing: /var/lib/tftpboot/grub/system_link removing: /var/lib/tftpboot/grub/images copying bootloaders running: ['rsync', '-rpt', '--copy-links', '--exclude=.cobbler_postun_cleanup', '/var/lib/cobbler/loaders/', '/var/lib/tftpboot'] received on stdout:  received on stderr:  running: ['rsync', '-rpt', '--copy-links', '--exclude=README.grubconfig', '/var/lib/cobbler/grub_config/', '/var/lib/tftpboot'] received on stdout:  received on stderr:  copying distros to tftpboot copying images generating PXE configuration files generating PXE menu structure rendering DHCP files generating /etc/dhcp/dhcpd.conf cleaning link caches running post-sync triggers running python triggers from /var/lib/cobbler/triggers/sync/post/* running python trigger cobbler.modules.sync_post_restart_services running: dhcpd -t -q received on stdout:  received on stderr:  running: service dhcpd restart received on stdout:  received on stderr: Redirecting to /bin/systemctl restart dhcpd.service  running shell triggers from /var/lib/cobbler/triggers/sync/post/* shell triggers finished successfully running python triggers from /var/lib/cobbler/triggers/change/* running python trigger cobbler.modules.scm_track running python trigger cobbler.modules.managers.genders running shell triggers from /var/lib/cobbler/triggers/change/* shell triggers finished successfully *** TASK COMPLETE ***
