1.1 cobbler简介

  Cobbler是一个Linux服务器安装的服务,可以通过网络启动(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等。

  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。

  Cobbler是较早前的kickstart的升级版,优点是比较容易配置,还自带web界面比较易于管理。

  Cobbler内置了一个轻量级配置管理系统,但它也支持和其它配置管理系统集成,如Puppet,暂时不支持SaltStack。

  Cobbler官网http://cobbler.github.io

  在使用cobbler之前需要了解kickstart的使用: http://www.cnblogs.com/clsn/p/7833333.html

1.1.1 cobbler集成的服务

    PXE服务支持

    DHCP服务管理

    DNS服务管理(可选bind,dnsmasq)

    电源管理

    Kickstart服务支持

    YUM仓库管理

    TFTP(PXE启动时需要)

    Apache(提供kickstart的安装源,并提供定制化的kickstart配置)

1.2 安装cobbler

1.2.1 环境说明

[root@Cobbler ~]# cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

[root@Cobbler ~]# uname -r
3.10.0-693.el7.x86_64

[root@Cobbler ~]# getenforce
Disabled

[root@Cobbler ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

[root@Cobbler ~]# hostname -I
10.0.0.202 172.16.1.202

yum源说明:

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

1.2.2 使用yum安装cobbler

yum -y install cobbler cobbler-web dhcp tftp-server pykickstart httpd

   说明:cobbler是依赖与epel源下载

1.2.3 cobbler语法检查前先启动http与cobbler

systemctl start httpd.service
systemctl start cobblerd.service
cobbler check

1.2.4 进行语法检查

[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.

1.2.5 解决当中的报错

命令集

sed -i s/server: 127.0.0.1/server: 172.16.1.202/ /etc/cobbler/settings

详解

解决1、2

cp /etc/cobbler/settings{,.ori}
sed -i s/server: 127.0.0.1/server: 172.16.1.202/ /etc/cobbler/settings
sed -i s/next_server: 127.0.0.1/next_server: 172.16.1.202/ /etc/cobbler/settings

问题3

sed s#yes#no#g /etc/xinetd.d/tftp -i

4下载包所需的软件包

[root@Cobbler ~]# cobbler get-loaders
[root@Cobbler ~]# ls  /var/lib/cobbler/loaders
COPYING.elilo     elilo-ia64.efi   menu.c32    yaboot
COPYING.syslinux  grub-x86_64.efi  pxelinux.0
COPYING.yaboot    grub-x86.efi     README

5启动rsync服务

[root@Cobbler ~]# systemctl start rsyncd.service
[root@Cobbler ~]# systemctl enable rsyncd.service

6 debian相关无需修改

7、修改安装完成后的root密码

openssl passwd -1 -salt random-phrase-here your-password-here
random-phrase-here  随机字符串
your-password-here 密码

示例

[root@Cobbler ~]# openssl passwd -1 -salt ‘CLSN‘ ‘123456‘
$1$CLSN$LpJk4x1cplibx3q/O4O/K/

管理dhcp

sed -i s/manage_dhcp: 0/manage_dhcp: 1/ /etc/cobbler/settings

防止重装

sed -i s/pxe_just_once: 0/pxe_just_once: 1/ /etc/cobbler/settings

修改dhcp模板

sed -i.ori s#192.168.1#172.16.1#g;22d;23d /etc/cobbler/dhcp.template

cobbler组配置文件位置

/etc/cobbler/settings

注意:修改完成之后要使用cobbler sync 进行同步,否则不生效。

1.2.6 修改之后

再次检查语法:

[root@Cobbler ~]# cobbler check
The following are potential configuration items that you may want to fix:

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

重启所有服务

systemctl restart httpd.service
systemctl restart cobblerd.service
systemctl restart dhcpd.service
systemctl restart rsyncd.service
systemctl restart tftp.socket

到此cobbler就安装完成,下面进行web界面的操作。

1.3 cobbler的web及界面操作

浏览器访问https://10.0.0.202/cobbler_web

   注意CentOS7中cobbler只支持https访问。

1.3.1 浏览器报500错误的解决方法

  
[root@localhost /]# rpm -qa | grep "python2-django"
python2-django-1.11.13-4.el7.noarch
这个包只要在1.8以上,就有问题
TEMPLATE_CONTEXT_PROCESSORS was deprecated in Django 1.8 and removed in Django 1.10. Its not possible to import it anymore.

解决方法
1、rpm -e --nodeps python2-django
2、yum install python2-pip
3、pip install --upgrade pip
4、pip install Django==1.8.17

 

   账号密码默认均为cobbler

1.3.1 操作说明--导入镜像

1)在虚拟机上添加上镜像

技术图片 

2)挂载上镜像

[root@Cobbler ~]# mount /dev/cdrom  /mnt/
mount: /dev/sr0 is write-protected, mounting read-only

[root@Cobbler ~]# df -h |grep mnt
/dev/sr0        4.3G  4.3G     0 100% /mnt

   3)进行导入镜像

 方式一:

   选择Import DVD  输入Prefix(文件前缀),Arch(版本),Breed(品牌),Path(要从什么地方导入)

   在导入镜像的时候要注意路径,防止循环导入。

   信息配置好后,点击run,即可进行导入。

 技术图片

导入过程使用rsync进行导入,三个进程消失表示导入完毕

[root@Cobbler mnt]# ps -ef |grep rsync
root   12026      1  0 19:04 ?   00:00:00 /usr/bin/rsync --daemon --no-detach
root  13554  11778 12 19:51 ?    00:00:06 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress
root   13555  13554  0 19:51 ?     00:00:00 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress
root   13556  13555 33 19:51 ?        00:00:17 rsync -a /mnt/ /var/www/cobbler/ks_mirror/CentOS7.4-x86_64 --progress
root   13590  10759  0 19:52 pts/1    00:00:00 grep --color=auto rsync

查看日志可以发现右running进程

      日志位于 Events

技术图片 

方式二:  

  1. cobbler import --path=/mnt/ --name=CentOS-7.1-x86_64 --arch=x86_64
  2. # --path 镜像路径
  3. # --name 为安装源定义一个名字
  4. # --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
  5. # 安装源的唯一标示就是根据name参数来定义,本例导入成功后,安装源的唯一标示就是:CentOS-7.1-x86_64,如果重复,系统会提示导入失败。

导入完成后生成的文件夹

[root@Cobbler ks_mirror]# pwd
/var/www/cobbler/ks_mirror

[root@Cobbler ks_mirror]# ls
CentOS7.4-x86_64  config

cd /var/lib/cobbler/kickstarts/

选择CentOS7.4即可进行安装,安装过程与光盘安装一致,这里就不在复述。

1.4 定制化安装操作系统

1.4.1 添加内核参数

1)查看导入的镜像,点击edit

   出现这个错误的原因是虚拟机的内存不足2G,

   将内存调为2G即可(这个错误只会出现在CentOS7.3之上)
