cobbler 无人值守-安装

环境准备

准备两台主机，如centos6和centos7
centos7当作server服务器
关闭selinux
关闭防火墙

安装

cobbler包光盘里是没有的，要配置epel源，这里就说怎么配置epel源了，在yum.repos.d/目录下照葫芦画瓢就可，配置好后执行如下命令安装

yum install –y cobbler

#

#

安装成功后，我们发现它还安装了其他的服务

备注：我们搭建cobbler-系统部署需要用到httpd、tftp-server、dhcp服务，从图上可以看出它没有安装dhcp服务，所以我们要安装下dhcp服务

yum install –y dhcp

#

#

开启服务

http服务

systemctl start httpd

#开启服务

systemctl enable httpd

#设置开机自启动

tftp-server服务

systemctl start tftp

#开启服务

systemctl enable tftp

#开机自启动

cobbler服务

systemctl start cobblerd

#开启服务

systemctl enable cobblerd

#开机自启动

cobbler环境检查

执行

cobbler check

#

会出现如下提示，配置缺少的东西

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

OK 根据提示一步一步来解决

步骤一

1、第一个提示：在/etc/cobbler/settings 文件中server字段必须要有一个别人可访问的IP地址，来提供网络服务，那么我们是在centos7上搭建的所以是本机地址。

①编辑配置文件

vim etc/cobbler/settings

#编辑配置文件

②刷新配置文件并环境检查

systemctl restart cobblerd

#重启服务，重新读取修改的配置文件

cobbler check

#环境检查

步骤二

#环境检查后发现少了一项，那么下面接着还是从第一项开始操作

1 : 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.

2 : change 'disable' to 'no' in /etc/xinetd.d/tftp

3 : 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.

4 : enable and start rsyncd.service with systemctl

5 : debmirror package is not installed, it will be required to manage debian deployments and repositories

6 : 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

7 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

如上第一条：'next_server' 地址不应该是127.0.0.1

所以修改它的地址，这个地址也就是你tftp服务器所在的主机地址，我们把服务都安装在一台主机上了，所以和上面地址一样

①编辑配置文件

vim etc/cobbler/settings

#编辑配置文件

②重复步骤一中的②命令来重读配置文件与环境检查

步骤三

#环境检查后发现又少了一条，下面接这来...

1 : change 'disable' to 'no' in /etc/xinetd.d/tftp

2 : 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.

3 : enable and start rsyncd.service with systemctl

4 : debmirror package is not installed, it will be required to manage debian deployments and repositories

5 : 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

6 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

如上第一条：提示更改/etc/xinetd.d/tftp配置文件中'disable'状态改为‘no’说白了也就是开启tftp服务

因为我们用的是centos7不需要xinetd.d了，前面已经开启了tftp服务，这步忽略，看下一个提示

第二条：在/var/lib/cobbler/loaders目录下少了一些必要的文件，用'cobbler get-loaders' 命令来获取，这时候需要主机联网下载

我们先来看看这个目录

①生成必要文件

cobbler get-loaders

#

#

我们知道出现的这些文件是要放在/var/lib/tftpboot/这里的，我们看下这个目录的信息

用如上环境检查中给出的提示进行同步

cobbler sync

#数据同步

再次查看下/var/lib/tftpboot目录结构

②重复步骤一中的②命令

#又少了，继续

1 : enable and start rsyncd.service with systemctl

2 : debmirror package is not installed, it will be required to manage debian deployments and repositories

3 : 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

4 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

步骤四

第一条：开启rsyncd.service 服务，我们没有用这个服务，忽略

第二条：是针对debian发行版的系统配置，忽略

第三条：修改kickstart文件的默认口令

①编辑配置文件

vim /etc/cobbler/settings

#

②重复步骤一中的②命令

#少了一条

1 : enable and start rsyncd.service with systemctl

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

如上第一、二上面说了忽略，看第三条，意思说配置电源项，和硬件有关，忽略

步骤五

配置dhcp

①编辑配置文件

vim /etc/cobbler/settings

#

② 改cobbler提供的dhcp配置文件模板

vim /etc/cobbler/dhcp.template

#

我们先来看下dhcp配置文件

还是空的没有配置信息

②同步

systemctl restart cobblerd

#重启服务

cobbler sync

#数据同步

再来看dhcp配置文件

有信息了

步骤六

①开启dhcp服务

systemctl start dhcpd

#开启服务

②建立cobbler yum源-导入系统

这里我们也把centos6导入

备注：它是放在了/var/www/目录下，同时生成了一个和系统同名的kickstart文件，

自带的kickstart文件是满足不了我们的需求的，所以我们使用自己的kickstart文件，之前生成过，直接拿来用。

步骤七

①编辑ks.cfg文件（前几篇提到过怎么创建改文件）

②把ks.cfg文件放在/var/lib/cobbler/kickstarts/下

③创建启动菜单

cobbler profile add --name=Centos-7.5-x86_64-Auto --distro=Centos-7.5-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks.cfg

#

cobbler profile add --name=Centos-6.9-x86_64-Auto --distro=Centos-6.9-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks6.cfg

#

④查看启动文件default是不是有了我们创建的自定义启动项

cat /var/lib/tftpboot/pxelinux.cfg/default

#查看启动菜单

备注：也可删除不需要的启动菜单

cobbler profile remove --name=Centos-6.9-x86_64

#

OK现在就可以用准备好的另一台主机测试了

备注：确保 http tftp dhcp 服务已开启防火墙以关闭 selinux以关闭

成功界面

cobbler-web管理

1、首先安装包

yum install -y cobbler-web

#

2、访问

https://192.168.43.7/cobbler_web

默认账号：cobbler

默认密码：cobbler

附带过程中出现的问题

问题一：出现如下提示：

解决方案：http：改为https:访问

问题二：安装新系统的时候，出现TFTP open timeout！

解决方案：关闭防火墙

#systemctl stop firewalld.service

#iptables –L

问题三：check环境检查的时在cobbler 候出现如下

解决方案：这是ip分配错误的提示，检查配置文件IP分配段

每个人遇到的问题可能不一样，查看日志检查，tailf -10 /var/log/messages
