cobbler批量装机系统centos 6.4下安装配置

简介: 最近笔者研究cobbler批量装机系统。 cobbler装机系统是较早前kickstart的升级版,优点比较容易配置,还自带web界面比较易于管理,不足在于中文资料较少。 这里就详细的介绍下笔者亲自经历的一次安装过程。

cobbler装机系统是较早前kickstart的升级版,优点比较容易配置,还自带web界面比较易于管理,不足在于中文资料较少。
这里就详细的介绍下笔者亲自经历的一次安装过程。
开始的时候笔者用的是centos 5.8系统,但是在安装cpbbler-web的时候报错,于是这次采用了centos6.4系统进行安装配置。

环境:
操作系统:CentOS 6.4

测试机器ip:10.0.0.128
先将iptables selinux 关掉。

/etc/init.d/iptables stop

chkconfig iptables off

setenforce 0

并修改配置文件/etc/sysconfig/selinux 将其disable
一、导入yum源,安装软件.

rpm -Uvh http://mirrors.hustunique.com/epel/6/x86_64/epel-release-6-8.noarch.rpm

yum install cobbler cobbler-web

yum install dhcp httpd

chkconfig cobblerd on

chkconfig httpd on

cobbler check

二:配置环境
1> 修改cobbler 的配置文件


Vi  /etc/cobbler/settings

修改如下地方:

next_server: 10.0.0.128

server: 10.0.0.128

manage_dhcp: 1

manage_rsync: 1

生成密码串

[root@puppet ~]# openssl passwd -1 -salt "cobber" "123456"  #举个简单例子"123456"

$1$cobber$yV9XfOuaaiVDvImopK7o.1
openssl passwd -1 -salt '
任间字符' '密码'
这个命令的用法,任意字符可以随便写,这个密码就是安装完系统root的密码了。替换配置文件里的字串。
vi  /etc/cobbler/settings
default_password_crypted: "$1$cobber$yV9XfOuaaiVDvImopK7o.1"
2>
启用tfpt rsync
vim /etc/xinetd.d/tftp
vim /etc/xinetd.d/rsync
disable的值修改成no
启动服务
/etc/init.d/xinetd restart
3>
修改dhcp的配置文件

# vi /etc/cobbler/dhcp.template

ddns-update-style interim;

allow booting;

allow bootp;

ignore client-updates;

set vendorclass = option vendor-class-identifier;

option pxe-system-type code 93 = unsigned integer 16;

subnet 10.0.0.0 netmask 255.255.255.0 {

     option routers             10.0.0.1;

     option domain-name-servers 8.8.8.8;

     option subnet-mask         255.255.255.0;

     range dynamic-bootp        10.0.0.2 10.0.0.100;

     default-lease-time         21600;

     max-lease-time             43200;

     next-server                $next_server;

   }

 

余下默认,只修改这个模板就行,cobbler 会同步到dhcp的配置。

5:客户端从网络启动后选择对应的工程文件开始自动部署


选择配置好的选项开始自动安装

完成后自动重启,可以用先前定义好的密码("123456")登陆了.

附:错误排除
# cobbler check
The following are potential configuration items that you may want to fix:
1 : Must enable a selinux boolean to enable vital web services components, run: setsebool -P httpd_can_network_connect true
2 : you need to set some SELinux content rules to ensure cobbler serves content correctly in your SELinux environment, run the following: /usr/sbin/semanage fcontext -a -t public_content_t "/tftpboot/.*" && /usr/sbin/semanage fcontext -a -t public_content_t "/var/www/cobbler"/images/.*
3 : you need to set some SELinux rules if you want to use cobbler-web (an optional package), run the following: /usr/sbin/semanage fcontext -a -t httpd_sys_content_rw_t "/var/lib/cobbler/webui_sessions/.*"
解决:关闭selinux
# vim /etc/sysconfig/selinux
SELINUX=disabled
4 : change 'disable' to 'no' in /etc/xinetd.d/tftp
解决:编辑/etc/xinetd.d/tftp文件,将文件中的disable字段的配置由yes改为no
5 : change 'disable' to 'no' in /etc/xinetd.d/rsync
解决:编辑/etc/xinetd.d/rsync文件,将文件中的disable字段的配置由yes改为no
6 : since iptables may be running, ensure 69, 80, and 25151 are unblocked
解决:在iptables中将698025151端口打开。如果仅仅只是在内部环境中使用,建议直接将防火墙关掉
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
解决:yum install debmirror
或:rpm -Uvh ftp://rpmfind.net/linux/epel/5/i386/debmirror-20090807-1.el5.noarch.rpm –nodeps –force
8 : ksvalidator was not found, install pykickstart
解决:yum install pykickstart
9 : 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
解决: 修改默认密码就OK了,然后把密码写入到/etc/cobbler/settings
# openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'
10 : comment 'dists' on /etc/debmirror.conf for proper debian support
11 : comment 'arches' on /etc/debmirror.conf for proper debian support
解决:注释/etc/debmirror.conf 下面两行
#@dists="sid";
@sections="main,main/debian-installer,contrib,non-free";
#@arches="i386";
12
fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them
解决: yum install cman
修复完成,再用 cobbler check 检查一下,确认没问题后用 cobbler sync 做同步操作:
# cobbler check
No configuration problems found. All systems go.

13. comment out 'dists' on /etc/debmirror.conf for proper debian support

comment out 'arches' on /etc/debmirror.conf for proper debian supportvim              vi /etc/debmirror.conf

#注释掉@dists="sid"@arches="i386即可

#@dists="sid";

#@arches="i386";

14. 较验cobbler check出错

Traceback (most recent call last):

 File "/usr/bin/cobbler", line 35, in ?

解决方法:此为BUG,按下方操作执行即

service cobblerd restart

cobbler get-loaders


返回这个结果就OK
