1)安装epel源和cobbler [root@cobbler~]#yum-yinstallhttp://mirrors.163.com/centos/7/extras/x86_64/Packages/epel-release-7-9.noarch.rpm[root@cobbler~]#yuminstallcobblercobbler-webdhcptftp-serverpykickstarthttpdxinetd-y[root@cobbler~]#sys

1)安装epel源和cobbler

[root@cobbler ~]# yum -y install http://mirrors.163.com/centos/7/extras/x86_64/Packages/epel-release-7-9.noarch.rpm [root@cobbler ~]# yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd xinetd -y [root@cobbler ~]# systemctl start xinetd.service [root@cobbler ~]# systemctl enable xinetd.service [root@cobbler ~]# systemctl start httpd [root@cobbler ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@cobbler ~]# systemctl start cobblerd.service [root@cobbler ~]# systemctl enable cobblerd.service Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.

2)配置cobbler

检查cobbler: [root@cobbler ~]# cobbler check The 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.

修改cobbler的配置文件:

[root@cobbler ~]# vim /etc/cobbler/settings # if you do not set this correctly, this will be manifested in TFTP open timeouts. 将“next_server: 127.0.0.1”修改为“next_server: 10.10.10.222” 将“server: 127.0.0.1”修改为“server: 10.10.10.222” # set to 1 to enable Cobbler's DHCP management features. # the choice of DHCP management engine is in /etc/cobbler/modules.conf 将“manage_dhcp: 0”修改为“manage_dhcp: 1”

修改cobbler默认的密码:

将“default_password_crypted: "$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."”修改为“default_password_crypted: "$1$wanwan$K9lP0CajD0pbFaxI0if84/"” 随机生成一个密码: [root@cobbler ~]# openssl passwd -1 -salt 'wanwan' 'redhat12345' $1$wanwan$K9lP0CajD0pbFaxI0if84/ [root@cobbler ~]# vim /etc/xinetd.d/tftp 将“disable                 = yes”修改为“disable                 = no”

重启rsync服务:

[root@cobbler ~]# systemctl start rsyncd.service [root@cobbler ~]# systemctl enable rsyncd.service Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

客户端设置从网卡启动:

CentOS7下利用cobbler部署CentOS_Linux

安装完的CentOS6:

CentOS7下利用cobbler部署CentOS_cobbler_02

cobbler的图形化管理界面(默认用户名cobbler,默认密码cobbler):

CentOS7下利用cobbler部署CentOS_Linux_03

CentOS7下利用cobbler部署CentOS_cobbler_04

CentOS7下利用cobbler部署CentOS_Linux_05

CentOS7下利用cobbler部署CentOS_Linux_06

CentOS7下利用cobbler部署CentOS_Linux_07

补充下,如果重启cobbler后发现dhcpd服务不能正常使用,很有可能是因为没设置自动启动

 [root@cobbler ~]# systemctl start dhcpd.service  [root@cobbler ~]# systemctl enable dhcpd.serviceCreated symlink from /etc/systemd/system/multi-user.target.wants/dhcpd.service to /usr/lib/systemd/system/dhcpd.service.
