cobbler list

列出所有的cobbler元素

cobbler report

列出元素的详细信息

cobbler sync

同步配置到数据目录,更改配置最好都要执行下

cobbler reposync

同步yum仓库

cobbler distro

查看导入的发行版系统信息

cobbler system

12.5.2. cobbler增加镜像

注意

本配置是在 cobbler安装配置 的基础上配置

如果是外接光驱挂载命令：

1[root@centos-cobbler ~]# mount /dev/cdrom /mnt/
2mount: block device /dev/sr0 is write-protected, mounting read-only

如果是把系统镜像文件传入cobbler服务器，则用：

1[root@centos-cobbler ~]# mount -o loop /data/CentOS-6.6-x86_64-bin-DVD1.iso /mnt/

把挂载的镜像加入cobbler仓库：

 1[root@centos-cobbler ~]# cobbler import --path=/mnt/ --name=CentOS-6.6-x86_64 --arch=x86_64
 2task started: 2018-10-20_165429_import

--path=PATH

必填项，镜像路径

--name

必选项，为安装源定义一个名字，是cobbler中镜像的唯一标识，不可以重复，如果重复，系统会提示导入失败。可以用参数 --rename 对已存在镜像重命名。

--arch=ARCH

非必选项，指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64

--breed=BREED

非必选项，标记系统版本。

12.5.2.1. 导入用光驱挂载的镜像

1mount /dev/cdrom /mnt/
2cobbler import --path=/mnt/ --name=CentOS-6.6-x86_64 --arch=x86_64

12.5.3. cobbler导入系统操作

删除导入的系统镜像

  • 查看导入的系统镜像

  • 删除导入的镜像

1[root@centos-cobbler ~]# cobbler distro list
2    CentOS-6.6-x86_64

12.5.4. 导入镜像配置kickstart文件

Cobbler会给镜像指定一个默认的kickstart自动安装文件在/var/lib/cobbler/kickstarts下的sample_end.ks

参考下面两个kickstart文件内容。

指定系统名称安装时使用指定的kickstart文件：

1cobbler profile edit --name=xxx --kickstart=/var/lib/cobbler/kickstarts/xxx.cfg
CentOS7控制网卡配置名称的参数：

  • net.ifnames=0

  • biosdevname=0

CentOS7安装的过程把网卡名称调整为ethx，

1cobbler profile edit --name=xxx --kopts='net.ifnames=0 biosdevname=0'

12.5.5. profile命令查看cobbler镜像所使用的参数

12.5.6. 用cobbler构建yum仓库

注意

导入镜像以后会自动构建一个对应的yum仓库：

仓库的位置： /var/www/cobbler/ks_mirror/CentOS-6.6-x86_64 其中 CentOS-6.6-x86_64 是导入的镜像名。

可以通过网页访问：http://192.168.6.10/cobbler/ks_mirror/CentOS-6.6-x86_64

cobbler自动化安装的系统会自动有一个 cobbler-config.repo 文件，这就是以cobbler服务器为yum源对应的yum源配置文件。

具体路径：

/etc/yum.repos.d/

修改yum源为cobbler的源：

cd /etc/yum.repos.d/

cp CentOS-Base.repo CentOS-Base.repo.ori

mv cobbler-config.repo CentOS-Base.repo

1cobbler repo add --name=CentOS-6-x86_64-epel --mirrro=https://mirrors.aliyun.com/epel/6/x86_64/ --arch=x86_64 --breed=yum

cobbler reposync

推送yum源到自动安装的客户机

1cobbler profile edit --name=xxx --repos="xxx"
2cobbler profile edit --name=CentOS-6.6-x86_64

12.5.7. cobbler安装时PXE界面设置

12.5.7.1. 开机启动项以及提示的链接

 1[root@centos-cobbler ~]# cat /etc/cobbler/pxe/pxedefault.template
 2DEFAULT menu
 3PROMPT 0
 4MENU TITLE Cobbler | http://cobbler.github.io
 5TIMEOUT 200
 6TOTALTIMEOUT 6000
 7ONTIMEOUT $pxe_timeout_profile
 8
 9LABEL local
10        MENU LABEL (local)
11        MENU DEFAULT
12        LOCALBOOT -1
13
14$pxe_menu_items
15
16MENU end

12.5.7.2. 调整开机启动项的顺序

如果调整开机启动项的顺序可以把上面 $pxe_timeout_profile 可以用 /var/lib/tftpboot/pxelinux.cfg/default 中的参数 LABEL 后面的参数替换。

例如 /var/lib/tftpboot/pxelinux.cfg/default ：

LABEL CentOS-6.6-x86_64

把 /etc/cobbler/pxe/pxedefault.template 中 $pxe_timeout_profile 替换为： CentOS-6.6-x86_64

12.5.7.3. PXE启动菜单加密码提示

参考文档：

https://cobbler.github.io/manuals/2.6.0/4/11_-_PXE-boot_Menu_Passwords.html

可以修改的文件包括两个：

  • 菜单密码：/etc/cobbler/pxe/pxedefault.template

  • 安装的系统引用密码：/etc/cobbler/pxe/pxeprofile.template

生成密码

1[root@centos-cobbler ~]# openssl passwd -1 -salt 123321 123
2$1$123321$KK2zXP/R/mQqLGasdNskP.

菜单密码添加到文件： /etc/cobbler/pxe/pxedefault.template

添加格式：

MENU MASTER PASSWD mypassword

在安装系统所有时都提示输入密码。需要在配置文件 /etc/cobbler/pxe/pxeprofile.template

添加格式(在 LABEL $profile_name 行下面)：

MENU PASSWD

修改后配置文件如下：

 1[root@centos-cobbler ~]# cat /etc/cobbler/pxe/pxedefault.template
 2DEFAULT menu
 3PROMPT 0
 4MENU TITLE Cobbler | http://cobbler.github.io
 5MENU MASTER PASSWD $1$123321$KK2zXP/R/mQqLGasdNskP.
 6TIMEOUT 200
 7TOTALTIMEOUT 6000
 8ONTIMEOUT $pxe_timeout_profile
 9
10LABEL local
11        MENU LABEL (local)
12        MENU DEFAULT
13        LOCALBOOT -1
14
15$pxe_menu_items
16
17MENU end
18[root@centos-cobbler ~]# cat /etc/cobbler/pxe/pxeprofile.template
19LABEL $profile_name
20        MENU PASSWD
21        kernel $kernel_path
22        $menu_label
23        $append_line
24        ipappend 2

配置后新机器通过PXE安装系统时进入下界面，然后通过方向键/tab键选择要安装的系统会提示输入密码(这个密码就是上面生成的密码123)：

../../../_images/cobbler-pxe-install001.png

12.5.8. cobbler同步所有配置项让其生效

一般如果修改了cobbler配置都需要同步配置才能使配置生效。

12.5.9. 根据mac地址让服务器自动安装对应的系统

根据mac可以有两种安装系统方式：

  • 通过命令添加mac地址对应的设备，然后自动化安装。

  • 通过python脚本，调用cobbler的api接口然后把mac对应的设备都添加到cobbler中然后自动化安装。

注意

上面两种方法都需要先知道要装系统的服务器的mac地址才可以。

12.5.9.1. 通过命令添加mac对应的设备然后装机

cobbler默认是local启动，如果需要自动安装，需要改PXE启动项，或者统计需要安装系统的服务器的mac地址，然后根据mac地址安装对应的cobbler中的系统。

具体步骤是：

服务器mac地址是： 00:0C:29:4F:FF:56

1[root@centos-cobbler ~]# cobbler system add --name=qd_web001 --hostname=qd_web001 \
2> --mac=00:50:56:3A:E0:B1 \
3> --profile=CentOS-6.6-x86_64 \
4> --ip-address=192.168.6.210 --subnet=255.255.255.0 --gateway=192.168.6.2 --interface=eth0 \
5> --static=1 --name-servers="114.114.114.114 8.8.8.8" \
6> --kickstart=/var/lib/cobbler/kickstarts/CentOS6-x86_64.ks

查看通过cobbler安装的系统的系统名称和通过上面命令指定mac地址要安装的系统名称：

1[root@centos-cobbler ~]# cobbler system list
2qd_web001

删除通过上面命令通过mac指定安装的设备，然后可以重新添加：

1[root@centos-cobbler ~]# cobbler system remove --name=qd_web001
2[root@centos-cobbler ~]# cobbler system list

12.5.9.2. 上面命令集合

1cobbler system add --name=qd_web001 --hostname=qd_web001 \
2--mac=00:50:56:3A:E0:B1 \
3--profile=CentOS-6.6-x86_64 \
4--ip-address=192.168.6.210 --subnet=255.255.255.0 --gateway=192.168.6.2 --interface=eth0 \
5--static=1 --name-servers="114.114.114.114 8.8.8.8" \
6--kickstart=/var/lib/cobbler/kickstarts/CentOS6-x86_64.ks
7
8cobbler system list
9cobbler system remove --name=qd_web001

12.5.9.3. python调用cobbler的api完成mac添加

python脚本如下：

下面的脚本名 cobbler_api.py

上传到cobbler服务器，然后执行即可：

[root@centos-cobbler ~]# python cobbler_api.py

 1#!/usr/bin/env python
 2# -*- coding: utf-8 -*-
 3
 4import xmlrpclib
 5
 6class CobblerAPI(object):
 7
 8    def __init__(self, url, user, password):
 9        self.cobbler_user = user
10        self.cobbler_pass = password
11        self.cobbler_url = url
12
13    def add_system(self, hostname, ip_add, mac_add, profile):
14
15        ret = {
16            "result": True,
17            "comment": [],
18        }
19
20        # get token
21        remote = xmlrpclib.Server(self.cobbler_url)
22        token = remote.login(self.cobbler_user, self.cobbler_pass)
23
24        # add system
25        system_id = remote.new_system(token)
26        remote.modify_system(system_id, "name", hostname, token)
27        remote.modify_system(system_id, "hostname", hostname, token)
28        remote.modify_system(system_id, "modify_interface", {
29            "macaddress-eth0": mac_add,
30            "ipaddress-eth0": ip_add,
31            "dnsname-eth0": hostname
32        }, token)
33        remote.modify_system(system_id, "profile", profile, token)
34        remote.modify_system(system_id, token)
35        try:
36            remote.sync(token)
37        except Exception as e:
38            ret['result'] = False
39            ret['comment'].append(str(e))
40        return ret
41
42def main():
43    SERVER_IP = '192.168.6.10'
44    cobbler = CobblerAPI("http://192.168.6.10/cobbler_api", "cobbler", "123")
45    #cobbler = CobblerAPI("http://{}/cobbler_api".format(SERVER_IP), "cobbler", "123")
46    ret = cobbler.add_system(hostname='cobbler-api-test', ip_add='192.168.6.20', mac_add='00:50:56:3A:E0:B1',
47                            profile='CentOS-6.6-x86_64')
48    print(ret)
49
50if __name__ == '__main__':
51    main()

测试cobbler的api：

 1#!/usr/bin/env python
 2# -*- coding: utf-8 -*-
 3
 4import xmlrpclib
 5
 6SERVER_IP = '192.168.6.10'
 7
 8remote = xmlrpclib.Server("http://192.168.6.10/cobbler_api")
 9#remote = xmlrpclib.Server("http://{}/cobbler_api".format(SERVER_IP))
10
11print(remote.get_distros())
12print(remote.get_profiles())
13print(remote.get_systems())
14print(remote.get_images())
15print(remote.get_repos())
