本文介绍了LINUX实操：CentOS7下利用Cobbler安装部署CentOS，希望对您有用。如果有疑问，可以联系我们。

CentOS7下应用Cobbler安装部署CentOS

Cobbler是一款快速的网络系统部署工具,其最大的特点是集合了所有系统部署所需服务,如DHCP、DNS、TFTP,这样你在部署一台操作系统的时候不需要在各个服务之前协调切换,Cobbler都可以替你来管理,Cobbler内部集成了一个镜像版本仓库,你可以自定义相关配置文件,实现不同系统不同安装需求的选择；当然,Cobbler还提供了包含yum源管理、Web界面管理、API接口、电源管理等功能,方便你自定义开发管理.

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)设置装备摆设cobbler

反省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.

改动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”改动为“next_server: 10.10.10.222”
将“server: 127.0.0.1”改动为“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”改动为“manage_dhcp: 1”

修改cobbler默认的暗码：

将“default_password_crypted: "$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."”修改为“default_password_crypted: "$1$wanwan$K9lP0CajD0pbFaxI0if84/"”
随机生成一个暗码：
[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.
