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/"'

六、同理安装centos5
