**一、cobbler：**

**1.cobbler介绍**

<table> 
 <tbody> 
 <tr> 
 <td>Cobbler是一个Linux服务器快速网络安装的服务，由python开发，小巧轻便（15k行python代码），可以通过PXE的方式来快速安装、重装物理服务器和虚拟机，同时还可以管理DHCP，DNS，TFTP、RSYNC以及yum仓库、构造系统ISO镜像。 Cobbler可以使用命令行方式管理，也提供了基于Web的界面管理工具(cobbler-web)，还提供了API接口，可以方便二次开发使用。</td> 
 </tr> 
 </tbody> 
</table>

**2.cobbler工作原理**

<table> 
 <tbody> 
 <tr> 
 <td><img src="https://img-blog.csdn.net/20180609143938200" alt=""> 1.client裸机配置了从网络启动后，开机后会广播包请求DHCP服务器 （cobbler server）发送其分配好的一个IP2.DHCP服务器（cobbler server）收到请求后发送responese，包括其ip地址 3.client裸机拿到ip后再向cobbler server发送请求IOS引导文件的请求 4.cobbler server告诉裸机OS引导文件的名字和TFTP server的ip和 port 5.client裸机通过上面告知的TFTP server地址通信，下载引导文件 6.client裸机执行执行该引导文件，确定加载信息，选择要安装的ios， 期间会再向cobbler server请求kickstart文件和ios image 7.cobbler server发送请求的kickstart和os iamge 8.client裸机加载kickstart文件 9.client裸机接收os image，安装该ios image</td> 
 </tr> 
 </tbody> 
</table>

**二、系统环境：**

**1.版本，ip**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# cat /etc/redhat-release&nbsp; CentOS Linux release 7.2.1511 (Core)&nbsp;[root@liang ~]# uname -r 3.10.0-327.el7.x86_64 [root@liang ~]# ifconfig eno16777736 eno16777736: flags=4163&lt;UP,BROADCAST,RUNNING,MULTICAST&gt; &nbsp;mtu 1500 &nbsp; &nbsp; &nbsp; &nbsp; inet 10.0.0.134 &nbsp;netmask 255.255.255.0 &nbsp;broadcast 10.0.0.255</td> 
 </tr> 
 </tbody> 
</table>

**2.关闭selinux,防火墙**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux&nbsp; [root@liang ~]# setenforce 0 [root@liang ~]# systemctl stop firewalld &nbsp; [root@liang ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service</td> 
 </tr> 
 </tbody> 
</table>

**三、安装步骤:  
1.安装epel包**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# yum install epel-release -y [root@liang ~]# yum makecache</td> 
 </tr> 
 </tbody> 
</table>

**2.安装所需的服务**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# yum install cobbler cobbler-web pykickstart dhcp xinetd tftp-server pykickstart httpd -y</td> 
 </tr> 
 </tbody> 
</table>

**3.启动httpd**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# systemctl start httpd [root@liang ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.</td> 
 </tr> 
 </tbody> 
</table>

**4.启动cobbler**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# systemctl start cobblerd [root@liang ~]# systemctl enable cobblerd Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service. </td> 
 </tr> 
 </tbody> 
</table>

**5.检查cobbler的配置（按提示将未配置的步骤配置完）**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# 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. &nbsp;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 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment: &nbsp; &nbsp; https://github.com/cobbler/cobbler/wiki/Selinux 4 : change 'disable' to 'no' in /etc/xinetd.d/tftp 5 : 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. &nbsp;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. 6 : enable and start rsyncd.service with systemctl 7 : debmirror package is not installed, it will be required to manage debian deployments and repositories 8 : 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 9 : 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. 第一步+第二步： [root@liang ~]# vim /etc/cobbler/settings server: 10.0.0.134 next_server: 10.0.0.134 manage_dhcp: 1 第三步： [root@liang ~]# vim /etc/sysconfig/selinux&nbsp; SELINUX=disabled [root@liang ~]# setenforce 0 [root@liang ~]# getenforce&nbsp; Permissive 第四步： [root@liang ~]# vim /etc/xinetd.d/tftp service tftp { &nbsp; &nbsp; &nbsp; &nbsp; socket_type &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = dgram &nbsp; &nbsp; &nbsp; &nbsp; protocol &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= udp &nbsp; &nbsp; &nbsp; &nbsp; wait &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= yes &nbsp; &nbsp; &nbsp; &nbsp; user &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= root &nbsp; &nbsp; &nbsp; &nbsp; server &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= /usr/sbin/in.tftpd &nbsp; &nbsp; &nbsp; &nbsp; server_args &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = -s /var/lib/tftpboot &nbsp; &nbsp; &nbsp; &nbsp; disable &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = no（将yes修改为no） &nbsp; &nbsp; &nbsp; &nbsp; per_source &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 11 &nbsp; &nbsp; &nbsp; &nbsp; cps &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 100 2 &nbsp; &nbsp; &nbsp; &nbsp; flags &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = IPv4 } 第五步： 下载缺少的文件 [root@liang ~]# cobbler get-loaders task started: 2018-06-08_101543_get_loaders task started (id=Download Bootloader Content, time=Fri Jun &nbsp;8 10:15:43 2018) 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 *** 第六步： [root@liang ~]# systemctl start rsyncd.service &nbsp; [root@liang ~]# systemctl enable rsyncd.service &nbsp; 第八步： [root@liang ~]# openssl passwd -1 -salt 'cobbler' '000000' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; $1$cobbler$yvUCMps1IlTa5ocamRXv1. [root@liang ~]# vim /etc/cobbler/settings default_password_crypted: "$1$cobbler$yvUCMps1IlTa5ocamRXv1." </td> 
 </tr> 
 </tbody> 
</table>

**6.重启服务**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# systemctl restart xinetd&nbsp; [root@liang ~]# systemctl restart cobblerd </td> 
 </tr> 
 </tbody> 
</table>

**7.剩下提示的步骤可以跳过**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment: &nbsp; &nbsp; https://github.com/cobbler/cobbler/wiki/Selinux 2 : debmirror package is not installed, it will be required to manage debian deployments and repositories 3 : 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.</td> 
 </tr> 
 </tbody> 
</table>

**8.配置dhcp(需要改dhcp服务的配置文件，只需要改cobbler的模板)**

<table> 
 <tbody> 
 <tr> 
 <td>[root@liang ~]# vim /etc/cobbler/dhcp.template&nbsp; subnet 10.0.0.0 netmask 255.255.255.0 { &nbsp; &nbsp; &nbsp;option routers &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 10.0.0.2; &nbsp; &nbsp; &nbsp;option domain-name-servers 10.0.0.2; &nbsp; &nbsp; &nbsp;option subnet-mask &nbsp; &nbsp; &nbsp; &nbsp; 255.255.255.0; &nbsp; &nbsp; &nbsp;range dynamic-bootp &nbsp; &nbsp; &nbsp; &nbsp;10.0.0.100 10.0.0.200; &nbsp; &nbsp; &nbsp;default-lease-time &nbsp; &nbsp; &nbsp; &nbsp; 21600; &nbsp; &nbsp; &nbsp;max-lease-time &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 43200; &nbsp; &nbsp; &nbsp;next-server &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$next_server; </td>
