Cobbler无人值守安装系统安装

1.Cobbler安装

1.1设置下主机名（我的IP是10.0.0.48）

[root@ cobbler48 ~]# hostnamectl set-hostname cobbler48

1.2 安装启动

[root@ cobbler48 ~]# yum -y install cobbler cobbler-webtftp-server pykickstart httpd dhc xinetd debmirror

[root@ cobbler48 ~]# systemctl start httpd cobblerd
[root@ cobbler48 ~]# systemctl enable httpd cobblerd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/sys徐娅 temd/system/httpd.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.

安装的组件的作用：

cobbler //程序包
cobbler-web //web 界面包
tftp-server //支持tftp服务
pykickstart // 检查kickstart 语法错误
httpd //apache
dhcp //dhcp服务
xinetd // 超级守护进程

1.3 配置Cobbler

[root@ cobbler48 ~]# cobbler check //检查 看需要修改那些地方
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 : comment out 'dists' on /etc/debmirror.conf for proper debian support
7 : comment out 'arches' on /etc/debmirror.conf for proper debian support
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.

在更改上卖弄的问题前，需要设置为可以动态设置

[root@ cobbler48 ~]# sed -ri '/allow_dynamic_settings:/c\allow_dynamic_settings: 1' /etc/cobbler/settings
[root@ cobbler48 ~]# grep allow_dynamic_settings /etc/cobbler/settings
allow_dynamic_settings: 1
[root@ cobbler48 ~]# systemctl restart cobblerd

1.3.1

解决第一个问题配置server地址　(1: /etc/cobbler/settings中的'server'字段必须设置为本地主机以外的其他内容，否则启动功能将不起作用。这应该是一个可解析的主机名或引导服务器的IP，所有使用它的机器都可以访问它。) /

[root@ cobbler48 ~]# cobbler setting edit --name=server--value=10.0.0.48

1.3.2

第二个问题配置next_server地址（2:为了使PXE起作用，“next_server”字段inuld匹配PXE网络上启动服务器的IP）

[root@ cobbler48 ~]# cobbler setting edit --name=next_server --value=10.0.0.48

1.3.3

第三个问题配置xinetd管理tftp （3:将/etc/xinetd.d/tftp中的“disable”改为“no”）

[root@ cobbler48 ~]# sed -ri '/disable/c\disable = no' /etc/xinetd.d/tftp
[root@ cobbler48 ~]# systemctl enable xinetd
[root@ cobbler48 ~]# systemctl restart xinetd

1.3.4

第四个问题（4:在/var/lib/cobbler/loaders中缺少一些网络引导加载程序，您可以运行'cobbler get-loaders'来下载它们，或者，如果您只想处理x86/x86_64网络引导，您可以确保您已经安装了一个*最新*版本的syslinux包，可以完全忽略这个消息。如果您希望支持所有架构，那么这个目录中的文件应该包括pxelinux。0,菜单。c32 elilo。efi, yaboot。'cobbler get-loaders'命令是解决这些需求的最简单方法。）

[root@ cobbler48 ~]# cobbler get-loaders // 可能会有点慢，千万不要断开

*** TASK COMPLETE ***

1.3.5

第五个问题（5:启用并启动rsyncd。服务与systemctl）

[root@ cobbler48 ~]# systemctl start rsyncd
[root@ cobbler48 ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

1.3.6

第六个问题（6：注释掉/etc/debmirr .conf上的“用户”，以获得适当的debian支持）

[root@ cobbler48 ~]#  sed -i 's#@dists="sid";#\#@dists="sid";#gp' /etc/debmirror.conf

1.3.7

第七个问题（7：注释掉/etc/debmirr .conf上的“拱门”以获得适当的debian支持）

[root@ cobbler48 ~]# sed -i 's#@arches="i386";#\#@arches="i386";#g' /etc/debmirror.conf

1.3.8

第八个问题（8:新安装机器的示例模板使用的默认密码(default_password_crypted in /etc/cobbler/settings)仍然设置为“补鞋匠”，应该更改，请尝试:“openssl passwd -1 -salt‘random-phrase-here’‘your-password-here’”以生成新密码）

[root@ cobbler48 ~]#  openssl passwd -1 -salt `openssl rand -hex 4` '123456'
$1$1a34d2f0$laBUxra8f0mUlyliQ0P/u0
[root@ cobbler48 ~]# cobbler setting edit --name=default_password_crypted --value='$1$1a34d2f0$laBUxra8f0mUlyliQ0P/u0'

1.3.9第九个问题（9:没有找到击剑工具，需要使用(可选的)电源管理功能。安装cman或栅栏代理来使用它们）

[root@ cobbler48 ~]# yum -y install fence-agents

1.3 重启服务检查所有的错误是否都解决了

1.6 创建一台新的虚拟机

文件 ——> 新建虚拟机 ——>下一步——>选择稍后安装操作系统——>下一步——>下一步——>选择路径然后一直下一步

1.7 开启虚拟机以后，需要关掉光盘连接（右键断开连接）重启出现蓝色界面成功

2 安装centos6.1

2.1 上传镜像（也可以上传其它Centos6的版本）

2.2 创建目录挂载（挂载成功可以到创建的目录下查看）

[root@ cobbler48 ~]# mkdir /centos6.1
[root@ cobbler48 ~]#  mount -o loop CentOS-6.10-x86_64-bin-DVD1.iso /centos6.1

2.3 导入镜像（这一步操作会有些慢稍安勿躁）

[root@ cobbler48 centos6.1]# cobbler import --path=/centos6.1 --name=centos6.1 --arch=x86_64

--path 镜像路径

--name 给源起一个名字

--arch 指定安装源是 32位 64位或者ia64

2.4 查看profile信息

[root@ cobbler48 centos6.1]#  cobbler distro report --name=centos6.1-x86_64

2.5 编写kickstarts 文件

[root@ cobbler48 centos6.1]# cd /var/lib/cobbler/kickstarts/
[root@ cobbler48 kickstarts]# cp sample_end.ks centos6.1.ks
[root@ cobbler48 kickstarts]# echo >centos6.1.ks
[root@ cobbler48 kickstarts]# vim centos6.1.ks
# This kickstart file should only be used with EL > 5 and/or Fedora > 7.
# For older versions please use the sample.ks kickstart file.
# Install OS instead of upgrade
install
# Use text mode install

# System keyboard

# System language

# System timezone

#Root password

# Do not configure the X Window System

# Run the Setup Agent on first boot

# Reboot after installation
reboot


%pre

# Start yum configuration

# End yum configuration

# End final steps

sed -ri "/^#UseDNS/c\UseDNS no" /etc/ssh/sshd_config
sed -ri "/^GSSAPIAuthentication/c\GSSAPIAuthentication no" /etc/ssh/sshd_config
%end

2.6 更新 kickstarts文件，验证是否修改成功，同步cobbler配置（每一次修改都要从新同步）

[root@ cobbler48 kickstarts]# cobbler profile edit --name=centos6.1-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.1.ks
[root@ cobbler48 kickstarts]# cobbler profile report --name=centos6.1-x86_64 |grep Kickstart
Kickstart                      : /var/lib/cobbler/kickstarts/centos6.1.ks
Kickstart Metadata             : {}
[root@ cobbler48 kickstarts]# cobbler sync

2.7 虚拟机自动安装

3 自动安装Centos7系统（如果本机是centos7 可以不用上传镜像）

3.1 创建镜像目录

[root@ cobbler48 ~]# mkdir centos7.3

3.2 挂载常见报错（找不到镜像）从新设置一下就好了

[root@ cobbler48 ~]# mount -o loop /dev/cdrom /centos7.3mount: /dev/sr0: failed to setup loop device: No mediumfound //报错
