这篇文章将为大家详细讲解有关Linux系统中如何安装Cobbler自动化部署，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
Cobbler是一个快速网络安装linux的服务，而且在经过调整也可以支持网络安装windows。该工具使用python开发，小巧轻便，使用简单的命令即可完成PXE网络安装环境的配置，同时还可以管理DHCP、DNS、以及yum仓库、构造系统ISO镜像。
Cobbler 服务端：CentOS Linux release 7.6.1810 Cobbler 服务端对内存的要求不高，只要能把Cobbler服务跑起来就行。 
#关闭 selinux 和防火墙[root@Jaking ~]# systemctl stop firewalld.service && systemctl disable firewalld.service && iptables -F && setenforce 0#永久关闭 selinux 执行下面命令[root@Jaking ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
首先安装 epel-release，Cobbler 和 tftp-server 在 base 源中是没有的
[root@Jaking ~]# yum install -y epel-release
安装 Cobbler 其实有一部分软件会被当做依赖进行安装上去，比如 tftp 和 httpd 服务，我们这里为了方便可以一并安装，避免后续出现相关问题。
[root@Jaking ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd
注意：必须把yum源配好，否则无法全部安装以上软件！
[root@Jaking ~]# vim /etc/yum.repos.d/CentOS-Base.repo#在CentOS-Base.repo配置文件中添加以下源[aliyun-os] name=aliyun-os baseurl=https://mirrors.aliyun.com/centos/7/os/x86_64/ enabled=1 gpgcheck=0 [aliyun-epel] name=aliyun-epel baseurl=https://mirrors.aliyun.com/epel/7/x86_64/ enabled=1 gpgcheck=0 [aliyun-extra] name=aliyun-extra baseurl=https://mirrors.aliyun.com/centos/7/extras/x86_64/ enabled=1 gpgcheck=0

首先启动 Cobbler 和 httpd 服务
[root@Jaking ~]# systemctl start cobblerd httpd
检查配置
[root@Jaking ~]# cobbler checkThe following are potential configuration items that you may want to fix: 1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it. 2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network. 3 : change 'disable' to 'no' in /etc/xinetd.d/tftp 4 : 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. 5 : enable and start rsyncd.service with systemctl 6 : debmirror package is not installed, it will be required to manage debian deployments and repositories 7 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one 8 : 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.
以上问题我们需要逐步解决。
问题 1：修改 server 地址为 192.168.1.7
[root@Jaking ~]# vim /etc/cobbler/settings改：390 server: 127.0.1 为：390 server: 192.168.1.7
问题 2：修改 next_server 地址为 192.168.1.7
[root@Jaking ~]# vim /etc/cobbler/settings改：278 next_server: 127.0.1 为：278 next_server: 192.168.1.7
问题 3：修改 tftp 服务被 xinetd 服务管理
[root@Jaking ~]# vim /etc/xinetd.d/tftp改：14 disable = yes 为：14 disable = no 顺便修改 xinetd 和 tftpd 服务开机启动 [root@Jaking ~]# systemctl start xinetd tftp && systemctl enable xinetd tftp
问题 4：下载操作系统引导文件
[root@Jaking ~]# cobbler get-loaderstask started: 2020-01-04_031204_get_loaders task started (id=Download Bootloader Content, time=Sat Jan 4 03:12:04 2020) 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 ***
问题 5：修改 rsyncd 服务为开机自启动状态并启用它。
[root@Jaking ~]# systemctl start rsyncd && systemctl enable rsyncd
问题 6：关于 debian 相关部署管理配置，忽略。
debmirror package is not installed, it will be required to manage debian deployments and repositories # debmirror 包尚未安装，需要它来管理 debian 部署和存储库
问题 7：修改操作系统默认密码
[root@Jaking ~]# openssl passwd -1 -salt 'root' '123456'$1$root$j0bp.KLPyr.u9kgQ428D10 [root@Jaking ~]# vim /etc/cobbler/settings改：101 default_password_crypted: "$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."为：101 default_password_crypted: "$1$root$j0bp.KLPyr.u9kgQ428D10"注：root 为用户描述，123456 为密码
问题 8：电源管理相关服务，忽略。
fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
修改完以上配置就可以检查 DHCP 配置了，由于 Cobbler 自动管理 DHCP 服务，我们只需要修改 Cobbler 中的模板配置文件即可。
[root@Jaking ~]# vim /etc/cobbler/dhcp.template改：22 option routers 192.168.1.5; #修改默认网关地址为：22 option routers 192.168.1.1; #以实际的网关为准改：23 option domain-name-servers 192.168.1.1; #修改 DNS 地址为：23 option domain-name-servers 114.114.114.114;
如下：
21 subnet 192.168.1.0 netmask 255.255.255.0 {
22 option routers 192.168.1.1;
23 option domain-name-servers 114.114.114.114;
24 option subnet-mask 255.255.255.0;
25 range dynamic-bootp 192.168.1.100 192.168.1.254;
26 default-lease-time 21600;
27 max-lease-time 43200;
28 next-server $next_server;注：配置默认为 192.168.1.0 网段，具体要看你的装机 vlan 划分，现在是实验环境所以保持配不变。 注：默认网关地址为 192.168.1.5，这里需要改成你自己局域网中的网关。 $next_server 为变量值为我们前面修改的主配置文件中的地址 192.168.1.7
修改 Cobbler 管理 dhcp 服务
[root@Jaking ~]# vim /etc/cobbler/settings改：242 manage_dhcp: 0 为：242 manage_dhcp: 1
同步配置文件，需要先重启 Cobblerd
[root@Jaking ~]# systemctl restart cobblerd[root@Jaking ~]# cobbler synctask started: 2020-01-04_032552_sync task started (id=Sync, time=Sat Jan 4 03:25:52 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 ***
注意观察 DHCP 服务是否启动。
重新检查，剩下 2 个可以忽略的问题。
[root@Jaking ~]# cobbler checkThe following are potential configuration items that you may want to fix: 1 : debmirror package is not installed, it will be required to manage debian deployments and repositories 2 : 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.
添加镜像
挂载光驱
[root@Jaking ~]# mount /dev/sr0 /mnt
导入镜像（时间较长）
[root@Jaking ~]# cobbler import --path=/mnt/ --name=CentOS-7.6 --arch=x86_64task started: 2020-01-04_033346_import task started (id=Media import, time=Sat Jan 4 03:33:46 2020) Found a candidate signature: breed=redhat, version=rhel6 Found a matching signature: breed=redhat, version=rhel6 Adding distros from path /var/www/cobbler/ks_mirror/CentOS-7.6-x86_64: creating new distro: CentOS-7.6-x86_64 trying symlink: /var/www/cobbler/ks_mirror/CentOS-7.6-x86_64 -> /var/www/cobbler/links/CentOS-7.6-x86_64 creating new profile: CentOS-7.6-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-7.6-x86_64 for CentOS-7.6-x86_64 processing repo at : /var/www/cobbler/ks_mirror/CentOS-7.6-x86_64 need to process repo/comps: /var/www/cobbler/ks_mirror/CentOS-7.6-x86_64 looking for /var/www/cobbler/ks_mirror/CentOS-7.6-x86_64/repodata/*comps*.xml Keeping repodata as-is :/var/www/cobbler/ks_mirror/CentOS-7.6-x86_64/repodata *** TASK COMPLETE ***
查看镜像，上面是镜像名称，下面是启动菜单。
[root@Jaking ~]# cobbler listdistros: CentOS-7.6-x86_64 profiles: CentOS-7.6-x86_64
同步 Cobbler 配置
[root@Jaking ~]# systemctl restart cobblerd[root@Jaking ~]# cobbler sync
