##1.1 Cobbler简介 Cobbler 可以用来快速建立 Linux 网络安装环境，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会。
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。 #####摘自百度百科 网络安装服务器套件 Cobbler(补鞋匠)从前，我们一直在做装机民工这份很有前途的职业。自打若干年前 Red Hat 推出了 Kickstart，此后我们顿觉身价倍增。不再需要刻了光盘一台一台地安装 Linux，只要搞定 PXE、DHCP、TFTP，还有那满屏眼花缭乱不知所云的 Kickstart 脚本，我们就可以像哈里波特一样，轻点魔棒，瞬间安装上百台服务器。这一堆花里胡哨的东西可不是一般人都能整明白的，没有大专以上学历，通不过英语四级， 根本别想玩转。总而言之，这是一份多么有前途，多么有技术含量的工作啊。很不幸，Red Hat 最新（Cobbler项目最初在2008年左右发布）发布了网络安装服务器套件 Cobbler(补鞋匠)，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会。对于我们这些在装机领域浸淫多年，经验丰富，老骥伏枥，志在千里的民工兄弟们来说，不为一个晴天霹雳。 ##1.2 环境准备
1. 查看系统版本 [root@linux-node1 ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core) 2. 内核版本 [root@linux-node1 ~]# uname -a Linux linux-node1 3.10.0-327.18.2.el7.x86_64 #1 SMP Thu May 12 11:03:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux 3. 确保selinux关闭 [root@linux-node1 ~]# getenforce Disabled 4. iptables 关闭 [root@linux-node1 ~]# iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination 5. 主机名 [root@linux-node1 ~]# hostname linux-node1 6. hosts本地解析 [root@linux-node1 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.56.11 linux-node1 linux-node1.example.com 192.168.56.12 linux-node2 linux-node2.example.com 7. 安装yum源 [root@linux-node1 ~]# rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
##1.3 安装Cobbler
[root@linux-node1 ~]# yum install cobbler cobbler-web pykickstart httpd dhcp tftp xinetd -y 包说明： cobbler #Cobbler程序包 cobbler-web #Cobbler的web服务包 pykickstart #Cobbler检查kickstart语法错误 httpd #Apache web服务 dhcp #Dhcp服务 tftp #Tftp服务
##1.4 重要配置文件注释：
[root@linux-node1 ~]# rpm -ql cobbler /etc/cobbler # 配置文件目录 /etc/cobbler/settings # cobbler主配置文件，这个文件是YAML格式，Cobbler是python写的程序。 /etc/cobbler/dhcp.template # DHCP服务的配置模板 /etc/cobbler/tftpd.template # tftp服务的配置模板 /etc/cobbler/rsync.template # rsync服务的配置模板 /etc/cobbler/iso # iso模板配置文件目录 /etc/cobbler/pxe # pxe模板文件目录 /etc/cobbler/power # 电源的配置文件目录 /etc/cobbler/users.conf # Web服务授权配置文件 /etc/cobbler/users.digest # 用于web访问的用户名密码配置文件 /etc/cobbler/dnsmasq.template # DNS服务的配置模板 /etc/cobbler/modules.conf # Cobbler模块配置文件 /var/lib/cobbler # Cobbler数据目录 /var/lib/cobbler/config # 配置文件 /var/lib/cobbler/kickstarts # 默认存放kickstart文件 /var/lib/cobbler/loaders # 存放的各种引导程序 /var/www/cobbler # 系统安装镜像目录 /var/www/cobbler/ks_mirror # 导入的系统镜像列表 /var/www/cobbler/images # 导入的系统镜像启动文件 /var/www/cobbler/repo_mirror # yum源存储目录 /var/log/cobbler # 日志目录 /var/log/cobbler/install.log # 客户端系统安装日志 /var/log/cobbler/cobbler.log # cobbler日志
##1.5 启动服务
cobbler的运行依赖于dhcp、tftp、rsync及dns服务。 [root@linux-node1 ~]# systemctl start httpd [root@linux-node1 ~]# systemctl start cobblerd [root@linux-node1 ~]# netstat -lntup Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 3182/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1879/master tcp 0 0 127.0.0.1:25151 0.0.0.0:* LISTEN 4707/python2 tcp6 0 0 :::80 :::* LISTEN 4678/httpd tcp6 0 0 :::22 :::* LISTEN 3182/sshd tcp6 0 0 ::1:25 :::* LISTEN 1879/master tcp6 0 0 :::443 :::* LISTEN 4678/httpd udp 0 0 0.0.0.0:35847 0.0.0.0:* 4122/dhclient udp 0 0 0.0.0.0:68 0.0.0.0:* 4122/dhclient udp6 0 0 :::11445 :::* 4122/dhclient
##1.6 检查Cobbler的配置，如果看不到下面的结果，再次执行systemctl start cobblerd
[root@linux-node1 ~]# 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. 针对上方问题的逐一解决： 1. 修改/etc/cobbler/settings文件中的server参数的值为提供cobbler服务的主机相应的IP地址或主机名"如server: 10.0.0.101"; 此命令可以更改两个参数解决 1，2问题。 sed -i 's/server: 127.0.0.1/server: 192.168.56.11/' /etc/cobbler/settings 检查: [root@linux-node1 ~]# grep 192.168.56.11 /etc/cobbler/settings next_server: 192.168.56.11 server: 192.168.56.11 2. 见上条命令结果检查; 3. 修改/etc/xinetd.d/tftp中的disable的参数修改为"disable = no"; 4. 按照提示执行"cobbler get-loaders"下载loaders; [root@linux-node1 ~]# cobbler get-loaders task started: 2016-06-02_223401_get_loaders 查看下载的内容： [root@linux-node1 ~]# ls /var/lib/cobbler/loaders/ COPYING.elilo COPYING.syslinux COPYING.yaboot elilo-ia64.efi grub-x86_64.efi grub-x86.efi menu.c32 pxelinux.0 README yaboot 5. 安装提示执行 "systemctl enable rsyncd"; [root@linux-node1 ~]# systemctl enable rsyncd 6. 待定; 7. 创建默认系统用户及密码： [root@linux-node1 ~]# openssl passwd -1 -salt 'root' 'password' $1$root$1fvaXuILgb4rdRlHdQ80N/ 修改密码为创建的加密码： [root@linux-node1 ~]# grep default_password /etc/cobbler/settings default_password_crypted: "$1$root$1fvaXuILgb4rdRlHdQ80N/" 8. 待定; 重启cobblerd后再做检查： 还差两项，一个为debian系统相关，一个为电源管理设备相关，此处暂不做调整; [root@linux-node1 ~]# systemctl restart cobblerd [root@linux-node1 ~]# 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.
##1.7 配置DHCP
此参数为1时表示使用，cobbler管理dhcp
[root@linux-node1 ~]# sed -i 's#manage_dhcp: 0#manage_dhcp: 1#g' /etc/cobbler/settings
[root@linux-node1 ~]# vim /etc/cobbler/dhcp.template
\#仅列出修改过的部分
\......
subnet 192.168.56.0 netmask 255.255.255.0 {
option routers 192.168.56.2;
option domain-name-servers 192.168.56.2;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.56.200 192.168.56.254;
\......
##1.8 同步Cobbler配置
\#同步最新cobbler配置，它会根据配置自动修改dhcp等服务。 [root@linux-node1 ~]# systemctl restart xinetd [root@linux-node1 ~]# systemctl restart cobblerd [root@linux-node1 ~]# cobbler sync task started: 2016-06-02_231553_sync task started (id=Sync, time=Thu Jun 2 23:15:53 2016) running pre-sync triggers cleaning trees removing: /var/lib/tftpboot/grub/images copying bootloaders trying hardlink /var/lib/cobbler/loaders/pxelinux.0 -> /var/lib/tftpboot/pxelinux.0 trying hardlink /var/lib/cobbler/loaders/menu.c32 -> /var/lib/tftpboot/menu.c32 trying hardlink /var/lib/cobbler/loaders/yaboot -> /var/lib/tftpboot/yaboot trying hardlink /usr/share/syslinux/memdisk -> /var/lib/tftpboot/memdisk trying hardlink /var/lib/cobbler/loaders/grub-x86.efi -> /var/lib/tftpboot/grub/grub-x86.efi trying hardlink /var/lib/cobbler/loaders/grub-x86_64.efi -> /var/lib/tftpboot/grub/grub-x86_64.efi copying distros to tftpboot copying images generating PXE configuration files generating PXE menu structure rendering DHCP files generating /etc/dhcp/dhcpd.conf rendering TFTPD files generating /etc/xinetd.d/tftp cleaning link caches running post-sync triggers running python triggers from /var/lib/cobbler/triggers/sync/post/* running python trigger cobbler.modules.sync_post_restart_services running: dhcpd -t -q received on stdout: received on stderr: running: service dhcpd restart received on stdout: received on stderr: Redirecting to /bin/systemctl restart dhcpd.service running shell triggers from /var/lib/cobbler/triggers/sync/post/* running python triggers from /var/lib/cobbler/triggers/change/* running python trigger cobbler.modules.scm_track running shell triggers from /var/lib/cobbler/triggers/change/* *** TASK COMPLETE *** #查看dhcp配置文件的标注开头证明自己由Cobbler管理 [root@linux-node1 ~]# less /etc/dhcp/dhcpd.conf \# ****************************************************************** \# Cobbler managed dhcpd.conf file \# generated from cobbler dhcp.conf template (Thu Jun 2 15:15:54 2016) \# Do NOT make changes to /etc/dhcpd.conf.

##1.10导入镜像文件
- 挂载系统光盘
[root@linux-node1 ~]# mount /dev/cdrom /mnt mount: /dev/sr0 写保护，将以只读方式挂载
- 导入操作系统来自于/mnt下
[root@linux-node1 ~]# cobbler import --path=/mnt/ --name=CentOS-7.2-x86_64 --arch=x86_64 task started: 2016-06-03_102402_import task started (id=Media import, time=Fri Jun 3 10:24:02 2016) Found a candidate signature: breed=redhat, version=rhel6 Found a candidate signature: breed=redhat, version=rhel7 Found a matching signature: breed=redhat, version=rhel7 Adding distros from path /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64: creating new distro: CentOS-7.2-x86_64 trying symlink: /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64 -> /var/www/cobbler/links/CentOS-7.2-x86_64 creating new profile: CentOS-7.2-x86_64 associating repos checking for rsync repo(s) checking for rhn repo(s) checking for yum repo(s) starting descent into /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64 for CentOS-7.2-x86_64 processing repo at : /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64 need to process repo/comps: /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64 looking for /var/www/cobbler/ks_mirror/CentOS-7.2-x86_64/repodata/*comps*.xml Keeping repodata as-is :/var/www/cobbler/ks_mirror/CentOS-7.2-x86_64/repodata *** TASK COMPLETE *** #参数注释： # --path 镜像路径 # --name 为安装源定义一个名字 # --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64 # 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-7.2-x86_64，如果重复，系统会提示导入失败。 #镜像存放目录，cobbler会将镜像中的所有安装文件拷贝到本地一份，放在/var/www/cobbler/ks_mirror下的CentOS-7.2-x86_64-distro-x86_64目录下。因此/var/www/cobbler目录必须具有足够容纳安装文件的空间。
- 区分多样化，在导入一份CentOS-6.6操作系统
[root@linux-node1 ~]# cobbler import --path=/mnt/ --name=CentOS-6.6-x86_64 --arch=x86_64
- 查看镜像列表：
[root@linux-node1 ~]# cobbler distro list CentOS-6.6-x86_64 CentOS-7.2-x86_64
- 镜像文件所在位置：
[root@linux-node1 ~]# ls /var/www/cobbler/ks_mirror/ CentOS-6.6-x86_64 CentOS-7.2-x86_64 config
- 删除指定的镜像文件img
[root@linux-node1 ~]# cobbler distro remove --name=CentOS-7xxx
##1.11指定ks.cfg文件调整内核参数
Cobbler使用ks.cfg文件来制定所需要的安装配置，分区，网络，主机名等开机优化操作，还可以指定系统安装相应的软件。
Cobbler-CentOS-7.2-x86_64.cfg
Cobbler-CentOS-6.6-x86_64.cfg
配置文件上传至至附件，见文章底部；
- Cobbler的默认ks.cfg文件存放位置；
[root@linux-node1 ~]# ls /var/lib/cobbler/kickstarts/ default.ks esxi5-ks.cfg legacy.ks sample_autoyast.xml sample_esx4.ks sample_esxi5.ks sample_old.seed esxi4-ks.cfg install_profiles pxerescue.ks sample_end.ks（默认使用的ks文件） sample_esxi4.ks sample.ks
- 上传准备好的cfg 文件到/var/lib/cobbler/kickstarts/路径，并修改distro list镜像对应的cfg文件；
[root@linux-node1 kickstarts]# cobbler profile edit --name=CentOS-7.2-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-7.2-x86_64.cfg [root@linux-node1 kickstarts]# cobbler profile edit --name=CentOS-6.6-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS-6.6-x86_64.cfg
- CentOS7系统网卡名变成eno…这种，为了运维标准化，我们需要修改为我们常用的eth0，使用下面的参数。但要注意是CentOS7才需要下面的步骤，CentOS6不需要。
[root@linux-node1 kickstarts]# cobbler profile edit --name=CentOS-7.2-x86_64 --kopts='net.ifnames=0 biosdevname=0'
- 查看安装img镜像文件信息

##1.12部署操作系统
- 新建一台机器，通过网络启动即可。
- 选择从Centos7.2安装系统。
- 登陆操作系统检查配置
##1.13定制化安装
-
Cobbler支持设备的物理MAC地址来区分设备，针对不同设备安装操作系统
-
查看虚拟机的MAC地址方法
-
Cobbler可以自定义配置网络接口，通过system来固定机器的IP、掩码、网关、DNS、主机名、等等实现基础环境标准化
[root@linux-node1 ~]# cobbler system add --name=linux-Centos7.2-test --mac=00:50:56:38:F3:C5 --profile=CentOS-7.2-x86_64 \ --ip-address=192.168.56.13 --subnet=255.255.255.0 --gateway=192.168.56.2 --interface=eth0 \ --static=1 --hostname=linux-node2.com --name-servers="192.168.56.2" \ --kickstart=/var/lib/cobbler/kickstarts/CentOS-7.2-x86_64.cfg \#--name 自定义，但不能重复
- 查看定义的列表
[root@linux-node1 ~]# cobbler system list linux-Centos7.2-test
- 打开MAC地址为"00:50:56:38:F3:C5"的机器发现会自动安装预选的操作系统
- 检查新安装的设备，IP、掩码、网关、DNS、主机名、等等配置
##1.14指定设备系统重装
- 有些需要重新安装的系统希望reboot后自动重装
- 在需要重装的机器上面！！！安装koan注意yum源
[root@linux-node2 ~]# rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm [root@linux-node2 ~]# yum install -y koan
- 检查在Cobbler上面有可选择的img
[root@linux-node2 ~]# koan --server=192.168.56.11 --list=profiles \- looking for Cobbler at http://192.168.56.11:80/cobbler_api CentOS-6.6-x86_64 CentOS-7.2-x86_64
