cobbler无人值守装机
作者：互联网
工作原理
1、环境
cat /etc/redhat-release uname -r getenforce systemctl status firewalld.service hostname -I
2、部署Cobbler
一、安装相关依赖包
yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web
二、启动相关服务
systemctl start httpd systemctl start cobblerd systemctl enable cobblerd systemctl enable httpd
三、通过cobbler check 核对当前设置是否有问题
cobbler check
四、修改/etc/cobbler/settings配置文件
sed -i 's/^server: 127.0.0.1/server: 10.0.0.42/' /etc/cobbler/settings sed -i 's/^next_server: 127.0.0.1/next_server: 10.0.0.42/' /etc/cobbler/settings
vim /etc/xinetd.d/tftp disable = no # yes修改为no
cobbler get-loaders
五、添加rsync到自启动并启动rsync
systemctl enable rsyncd systemctl start rsyncd
六、修改密码为123456 ，salt后面是常用的方式加密
[root@ c7-42 ~]# openssl passwd -1 -salt '123456' '123456' $1$123456$wOSEtcyiP2N/IfIl15W6Z0 [root@ c7-42 ~]# vim /etc/cobbler/settings # 修改settings配置文件中下面位置，把新生成的密码加进去 default_password_crypted: "$1$123456$wOSEtcyiP2N/IfIl15W6Z0"
再次执行cobbler check
[root@ c7-42 ~]# cobbler check
七、配置cobbler-DHCP
[root@ c7-42 ~]# vim /etc/cobbler/settings manage_dhcp: 1
修改dhcp.templates配置文件
subnet 10.0.0.0 netmask 255.255.255.0 {
option routers 10.0.0.42; #本机ip
option domain-name-servers 10.0.0.42; #本机ip
option subnet-mask 255.255.255.0;
range dynamic-bootp 10.0.0.100 10.0.0.254; #新建的虚拟机ip范围
default-lease-time 21600;
max-lease-time 43200;
重启服务并同步配置，改完dhcp必须要sync同步配置
[root@ c7-42 ~]# systemctl restart cobblerd.service [root@ c7-42 ~]# cobbler sync task started: 2020-05-04_181138_sync task started (id=Sync, time=Mon May 4 18:11:38 2020) running pre-sync triggers cleaning trees removing: /var/lib/tftpboot/grub/images copying bootloaders trying hardlink /var/lib/cobbler/loaders/pxelinux.0 -> /var/lib/tftpboot/pxelinux.0 trying hardlink /var/lib/cobbler/loaders/menu.c32 -> /var/lib/tftpboot/menu.c32 trying hardlink /var/lib/cobbler/loaders/yaboot -> /var/lib/tftpboot/yaboot trying hardlink /usr/share/syslinux/memdisk -> /var/lib/tftpboot/memdisk trying hardlink /var/lib/cobbler/loaders/grub-x86.efi -> /var/lib/tftpboot/grub/grub-x86.efi trying hardlink /var/lib/cobbler/loaders/grub-x86_64.efi -> /var/lib/tftpboot/grub/grub-x86_64.efi copying distros to tftpboot copying images generating PXE configuration files generating PXE menu structure rendering DHCP files generating /etc/dhcp/dhcpd.conf rendering TFTPD files generating /etc/xinetd.d/tftp 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/* running python triggers from /var/lib/cobbler/triggers/change/* running python trigger cobbler.modules.manage_genders running python trigger cobbler.modules.scm_track running shell triggers from /var/lib/cobbler/triggers/change/* *** TASK COMPLETE ***
检查dhcp
[root@ c7-42 ~]# netstat -lnup|grep dhcp udp 0 0 0.0.0.0:67 0.0.0.0:* 3265/dhcpd
3、导入CentOs-7的镜像
一、挂载光盘镜像
[root@ c7-42 ~]# mount /dev/cdrom /mnt mount: /dev/sr0 is write-protected, mounting read-only
二、cobbler导入镜像
[root@ c7-42 ~]# cobbler import --path=/mnt --name=Centos-7.7 --arch=x86_64 task started: 2020-05-04_181209_import task started (id=Media import, time=Mon May 4 18:12:09 2020) Found a candidate signature: breed=redhat, version=rhel6 Found a candidate signature: breed=redhat, version=rhel7 Found a matching signature: breed=redhat, version=rhel7 Adding distros from path /var/www/cobbler/ks_mirror/Centos-7.7-x86_64: creating new distro: Centos-7.7-x86_64 trying symlink: /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 -> /var/www/cobbler/links/Centos-7.7-x86_64 creating new profile: Centos-7.7-x86_64 associating repos checking for rsync repo(s) checking for rhn repo(s) checking for yum repo(s) starting descent into /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 for Centos-7.7-x86_64 processing repo at : /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 need to process repo/comps: /var/www/cobbler/ks_mirror/Centos-7.7-x86_64 looking for /var/www/cobbler/ks_mirror/Centos-7.7-x86_64/repodata/*comps*.xml Keeping repodata as-is :/var/www/cobbler/ks_mirror/Centos-7.7-x86_64/repodata *** TASK COMPLETE *** # --path 镜像路径 # --name 为安装源定义一个名字 # --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64 # 安装源的唯一标示就是根据name参数来定义，本例导入成功后，安装源的唯一标示就是：CentOS-7.1-x86_64，如果重复，系统会提示导入失败
三、导入完镜像以后，那么就使查看下cobbler
[root@ c7-42 ~]# cobbler list distros: Centos-7.7-x86_64 profiles: Centos-7.7-x86_64 systems: repos: images: mgmtclasses: packages: files:
四、配置ks
[root@ c7-42 ~]# cd /var/lib/cobbler/kickstarts [root@ c7-42 kickstarts]# cp sample_end.ks CentOS7.7-x86_64.ks
[root@ c7-42 kickstarts]# cobbler profile list Centos-7.7-x86_64
[root@ c7-42 kickstarts]# cobbler profile edit --name Centos-7.7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS7.7-x86_64.ks
[root@ c7-42 kickstarts]# cobbler profile edit --name Centos-7.7-x86_64 --kopts='net.ifnames=0 biosdevname=0'
