部署安装cobbler,实现批量安装CentOS7、Ubuntu17.04、Ubuntu18.04（快捷版）

一.部署安装cobbler

yum安装cobbler

[root@localhost ~]# yum install -y net-tools

[root@localhost ~]# yum install -y httpd dhcp tftp  cobbler   cobbler-web
[root@localhost ~]# yum install xinetd

[root@localhost ~]# systemctl start httpd
[root@localhost ~]# systemctl enable httpd

[root@localhost ~]# systemctl start cobblerd
[root@localhost ~]# systemctl enable  cobblerd

1.编辑cobbler配置文件

[root@localhost ~]# vim /etc/cobbler/settings
....................
server: 192.168.4.15

next_server: 192.168.4.15
....................
virt_auto_boot: 1
....................

2.持续安装所需文件

[root@localhost ~]# cobbler get-loaders

3.配置tftp

[root@localhost ~]# vim /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

[root@localhost ~]# systemctl enable rsyncd
[root@localhost ~]# systemctl start  rsyncd

启动xinetd

[root@localhost ~]# systemctl  restart   xinetd
[root@localhost ~]# systemctl  enable   xinetd

4.安装pykickstart

[root@localhost ~]# yum install  pykickstart  -y

5.设置密码

设置密码、随机值123456 密码123456

[root@localhost ~]# openssl passwd -1 -salt '123456' '123456'
$1$123456$wOSEtcyiP2N/IfIl15W6Z0

更改默认密码为：

[root@localhost ~]# vim  /etc/cobbler/settings
default_password_crypted: "$1$123456$wOSEtcyiP2N/IfIl15W6Z0"
[root@localhost ~]# systemctl restart cobblerd

6.cobbler管理DHCP

[root@localhost ~]# vim /etc/cobbler/settings
manage_dhcp: 1

第一次修改模板文件。修改模板文件，生成dhcp配置文件。大致更改的地方有

[root@localhost ~]# vim /etc/cobbler/dhcp.template

subnet 192.168.4.0 netmask 255.255.255.0 {
     option routers             192.168.4.2;
     option domain-name-servers 192.168.4.2;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.4.100 192.168.4.254;
...................

重启cobblerd

[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# cobbler sync

7.编辑启动应用服务脚本

[root@localhost ~]# vim start.sh
#!/bin/bash
systemctl restart httpd
systemctl restart dhcpd
systemctl restart tftp
systemctl restart cobblerd
systemctl restart xinetd
systemctl restart rsyncd

二、镜像导入以及自动化文件必读须知

preseed文件参考网址如下：

• 模板位置：http://www.debian.org/releases/wheezy/example-preseed.txt
• 官方的安装手册：http://www.debian.org/releases/wheezy/i386/

live、desktop的ubuntu18.04镜像不能使用cobller做为iso导入。请使用server-amd64。附带下载连接地址如下：

• http://cdimage.ubuntu.com/releases/

cobbler+ubuntu不能使用kickstart的cfg文件的格式，做为自动化菜单安装的实现文件。ubuntu操作系统使用ks.cfg文件会被强制转为preseed文件内容实现。所以，附带以下ubuntu.seed文件内容跟，参考。

1.Centos7自动化操作系统安装

上传iso镜像，挂载/mnt下，导入文件内容到cobbler中

[root@localhost ~]# mount ubuntu-18.04.5-server-amd64.iso   /mnt/
[root@localhost ~]# cobbler  import --path=/mnt/  --name=Ubuntu-18.04.3  --arch=x86_64  --kickstart=/var/lib/cobbler/kickstarts/ubuntu18.seed

查看cobbler的相关信息，发现ubuntu18.04导入是两个Ubuntu-18.04.3-x86_64、Ubuntu-18.04.3-hwe-x86_64

查看镜像相关的seed或cfg自动化引导安装文件

以下有此两个信息检查信息提示，不必在意

The following are potential configuration items that you may want to fix:

1 : One or more repos need to be processed by cobbler reposync for the first time before kickstarting against them: Ubuntu-18.04.3-x86_64, Ubuntu-18.04.3-hwe-x86_64
2 : 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.
