cobbler批量部署(centos5-7)

我的博客已迁移到xdoujiang.com请去那边和我交流
Cobbler is an install server; batteries are included
Cobbler is a Linux installation server that allows for rapid setup of network installation environments.
It glues together and automates many associated Linux tasks so you do not have to hop between lots of 
various commands and applications when rolling out new systems, and, in some cases, changing existing ones.
With a simple series of commands, network installs can be configured for PXE, reinstallations, 
media-based net-installs, and virtualized installs (supporting Xen, qemu, KVM, and some variants of VMware). 
Cobbler uses a helper program called koan (which interacts with Cobbler) for reinstallation and virtualization support.   
Cobbler is a small and lightweight application (about 15k lines of Python code). It tries to be extremely 
simple to use both for very small and very large installations -- as well as easy to work on, extend, and hack. 
It avoids being "enterprisey" (as in complicated) whenever possible, but is highly useful in all sorts of 
enterprises by having a lot of advanced features and doing small things to save a large amount of time in repeated tasks.
Cobbler can also optionally help with managing DHCP, DNS, and yum package mirroring infrastructure -- in this regard, 
it is a more generalized automation app, rather than just dealing specifically with installations. 
There is also a lightweight built-in configuration management system, as well as support for integrating 
with configuration management systems like Puppet.  Cobbler has a command line interface, a web interface
and also several API access options.  That sounds like a lot, but it is really pretty simple. 
New users may like to start with the web app after doing the initial setup steps on the command line 
(cobbler check; cobbler import) as it will give them a good idea of all of the features available.
Advanced features do not have to be understood all at once, they can be incorporated over time as the need for them arises.

一、基础环境
1、角色、ip、版本、内核
serverA 192.168.1.30 3.10.0-229.el7.x86_64 CentOS Linux release 7.1.1503 (Core) cobbler dnsmasq httpd tftp-server
cobbler-2.6.9-1
dnsmasq-2.66-14
httpd-2.4.6-31
tftp-server-5.2-11
CentOS-5.9-x86_64-bin-DVD-1of1.iso
CentOS-5.9-x86_64-bin-DVD-2of2.iso
CentOS-6.7-x86_64-bin-DVD1.iso
CentOS-6.7-x86_64-bin-DVD2.iso
CentOS-7-x86_64-Everything-1503-01.iso

2、关闭防火墙和selinux
1)查看到当前已经关闭防火墙了
systemctl status firewalld.service
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
   Active: inactive (dead)
2)查看到selinux还开着
getenforce 
Enforcing
3)关闭selinux
sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/selinux/config
setenforce 0

二、安装cobbler(serverA)
1、安装所需要的包
yum -y install cobbler pykickstart openssl fence-agents dnsmasq syslinux

2、设置开机启动
1)设置http服务开机启动
systemctl enable httpd.service
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
2)设置dnsmasq服务开机启动
systemctl enable dnsmasq.service
ln -s '/usr/lib/systemd/system/dnsmasq.service' '/etc/systemd/system/multi-user.target.wants/dnsmasq.service'
3)设置cobblerd服务开机启动
systemctl enable cobblerd.service
ln -s '/usr/lib/systemd/system/cobblerd.service' '/etc/systemd/system/multi-user.target.wants/cobblerd.service'

3、确认cobbler已经正常启动
1)查看cobbler端口
netstat -tupnl |grep python
tcp        0      0 127.0.0.1:25151         0.0.0.0:*               LISTEN      2033/python2
2)查看cobbler进程
ps -ef |grep cobbler
root       2033      1  0 10:37 ?        00:00:00 /usr/bin/python2 /usr/bin/cobblerd -F

4、执行cobbler检查
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 : file /etc/xinetd.d/rsync does not exist
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
Restart cobblerd and then run 'cobbler sync' to apply changes.

5、解决以上问题
1)备份配置
cp /etc/cobbler/settings /etc/cobbler/settings.bak
2)生成root密码为redhat
openssl passwd -1 -salt 'root' 'redhat'
$1$root$M1uN9dLHipbORRwJW/xR3/
3)修改配置
sed -i 's/^server:.*/server: 192.168.1.30/' /etc/cobbler/settings
sed -i 's/^next_server:.*/next_server: 192.168.1.30/' /etc/cobbler/settings
sed -i '/default_password_crypted/c\default_password_crypted:\ "$1$root$M1uN9dLHipbORRwJW/xR3/"' /etc/cobbler/settings
sed -i 's/^manage_dhcp:.*/manage_dhcp: 1/' /etc/cobbler/settings
sed -i 's/^manage_dns:.*/manage_dns: 1/' /etc/cobbler/settings
sed -i 's/^manage_tftpd:.*/manage_tftpd: 1/' /etc/cobbler/settings
sed -i 's/^restart_dhcp:.*/restart_dhcp: 1/' /etc/cobbler/settings
sed -i 's/^restart_dns:.*/restart_dns: 1/' /etc/cobbler/settings
sed -i 's/^pxe_just_once:.*/pxe_just_once: 1/' /etc/cobbler/settings
PS:debmirror包在源里已经去除 第6条可以无视
4)下载pxelinux.0和menu.c32等文件

3)修改默认的模板为centos模板
cobbler profile edit --name=CentOS6.7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos6.7x86_64.cfg
4)查看到现在已经在使用centos6.7x86_64.cfg配置文件了

11、重启全部服务
systemctl restart cobblerd.service
systemctl restart dnsmasq.service
systemctl restart httpd.service
systemctl restart xinetd.service

12、查看进程
root      11120  1.1  6.2 363472 30216 ?        Ss   13:07   0:00 /usr/bin/python2 /usr/bin/cobblerd -F

13、查看端口是否都开放了(53 67 69 80)
netstat -tupnl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

三、测试
1、客户端安装的时候按F12网络引导就OK了,这里选择centos6安装

四、配置安装centos7
1、挂载并导入dvd iso
1)挂载dvd
cd /opt && mount -o loop CentOS-7-x86_64-Everything-1503-01.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only
2)导入

3)卸载
umount /mnt

2、查看到已经有centos6.7和centos7了
cobbler profile list
   CentOS6.7-x86_64
   centos7-x86_64

3、看到default文件里已经有centos6.7和centos7了
cat /var/lib/tftpboot/pxelinux.cfg/default

        ipappend 2
MENU end

4、可以修改或复制之前的kictstart模板
cp /var/lib/cobbler/kickstarts/centos6.7x86_64.cfg /var/lib/cobbler/kickstarts/centos7x86_64.cfg

5、修改centos7使用centos7x86_64.cfg模板
cobbler profile edit --name=CentOS7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7x86_64.cfg

6、最后看下报告

五、继续测试
1、客户端安装的时候按F12网络引导就OK了,这里选择centos7安装

六、同理安装centos5
