1）安装epel源和cobbler
[[email protected] ~]# yum -y install http://mirrors.163.com/centos/7/extras/x86_64/Packages/epel-release-7-9.noarch.rpm [[email protected] ~]# yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd xinetd -y [[email protected] ~]# systemctl start xinetd.service [[email protected] ~]# systemctl enable xinetd.service [[email protected] ~]# systemctl start httpd [[email protected] ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [[email protected] ~]# systemctl start cobblerd.service [[email protected] ~]# 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： [[email protected] ~]# 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：
[[email protected] ~]# 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： [[email protected] ~]# openssl passwd -1 -salt ‘wanwan‘ ‘redhat12345‘ $1$wanwan$K9lP0CajD0pbFaxI0if84/ [[email protected] ~]# vim /etc/xinetd.d/tftp 将“disable = yes”修改为“disable = no”
重启rsync服务：
[[email protected] ~]# systemctl start rsyncd.service [[email protected] ~]# systemctl enable rsyncd.service Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

}
}
