CentOS-5.5-x86_64 cobbler 自动化部署配置

CnetOS 5.5安装cobbler

 参考网上的一下教程，整理一下便于日后用

 

一、安装第三方rpmforge包

下载网址：http://www.rpmfind.net/linux/rpm2html/search.php?query=rpmforge-release

shell>wget http://www.rpmfind.net/linux/rpm2html/search.php?query=rpmforge-release
wget ftp://195.220.108.108/linux/dag/redhat/el5/en/x86_64/dag/RPMS/rpmforge-release-0.5.3-1.el5.rf.x86_64.rpm  

shell>rpm –ivh rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

 

(Centos5 64位: rpm -Uvh
http://mirrors.ustc.edu.cn/fedora/epel/5/x86_64/epel-release-5-4.noarch.rpm)  
二、安装cobblerhttpd rsync tftp-server xinetd dhcp服务

shell>yum install –y install cobbler httpdrsync tftp-server xinetd dhcp -y

 

检查syslinux是否已经安装

shell>yum install syslinux –y

 

三、手动开启wsgi模块

vim /etc/httpd/conf.d/wsgi.conf

#LoadModule wsgi_module modules/mod_wsgi.so 前面#去掉即可

 

四、启动相关服务

shell>service cobblerd restart

shell>service httpd restart

 

设置服务开机自启动，开启服务，如果在chkconfig –list中没有的服务，需要手动添加

chkconfig –list   查看相关服务有没有列出来，如dhcpd没有在列表中，则执行下一下命令：

chkconfig –add dhcpd

chkconfig –level 345 dhcpd on

 

确保服务开机自启动

chkconfig httpd on

chkconfig dhcpd on

chkconfig xinetd on

chkconfig cobblerd on

chkconfig rsync on

 

service httpd start

 

挂载镜像文件到mnt文件目录

shell> mount -o loop /data/iso/CentOS-5.5-x86_64-bin-DVD-1of2/mnt/cdrom/ #挂载光盘镜像

在虚拟机中可以设置：可移动设备->cd/dvd(sata)->连接(先设置iso文件)，然后执行命令

mount /dev/cdrom /mnt -r   #挂载cdrom下的光盘镜像到/mnt 下

接着执行命令cobblerdistro list查看是否有导入的文件

导入OS镜像：

mkdir /mnt/centos_iso

mount -o loop ./iso/CentOS-6.5-x86_64-minimal.iso /mnt/centos_iso

cobbler import --arch=x86_64 --path=/mnt/centos_iso--name=CentOS-6.5

 

再次同步修改：

cobbler sync

 

 

制作cobbler启动菜单

shell> cobbler import --path=/data/iso/ --name=CentOS-5.5-x86_64

 

五、修改配置文件

修改rsync配置文件修改

#vi /etc/xinetd.d/rsync

disable = yes 改成no     //开启rsync

 

修改tftp配置文件

#vi /etc/xinetd.d/tftp

disable = yes 改成no     //开启tfpt

 

修改cobbler配置文件

vi /etc/cobbler/settings

next_server: '127.0.0.1'  //改成本机IP：192.168.1.102

server: '127.0.0.1'           //改成本机IP：192.168.1.102

manage_dhcp: 0               //改成1 //开启管理DHCP服务

manage_tftpd: 0               //改成1 //开启管理DHCP服务

default_password_crypted:"$1$mF86/UHC$WvcIcX2t6crBz2onWxyac."    //root用户密码，可以用命令行得到加密的密码，具体用法如下：

shell> openssl passwd -apr1 -salt 'openssl rand -hex 4'

Password: #输入密码

$apr1$openssl $aA7bNBhsYJPhUH8z6mKS3/

 

 

修改 dhcp的配置

#vi /etc/cobbler/dhcp.template

ddns-update-style interim;

allow booting;

allow bootp;

ignore client-updates;

set vendorclass = option vendor-class-identifier;

subnet 192.168.1.0 netmask 255.255.255.0 {

#option routers 192.168.1.1;

#option domain-name-server 192.168.0.100;

option subnet-mask 255.255.255.0;

range dynamic-bootp 192.168.1.2 192.168.1.200;

filename "/pxelinux.0";

default-lease-time 21600;

max-lease-time 43200;

next-server $next_server;

}

……………………

 

编辑ks文件 
模板文件位置位于/var/lib/cobbler/kickstarts/目录下

vi /etc/cobbler/default.ks

……

 

六、同步cobbler配置使之生效

shell> service cobblerd restart

shell> service httpd restart

shell> service xinetd restart

shell> cobbler sync

shell> service dhcpd restart

 

 

至此服务器的配置工作完成客户端开机

 

在检查cobbler中，发现一下错误：

shell>cobbler check

 

错误：

1 : 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 youhave installed a *recent* version of the syslinux package
installed and canignore this message entirely.  Files inthis directory, should you want to support all architectures, should includepxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' commandis the easiest way to resolve these requirements.

2 : debmirror package is not installed, it will be required tomanage debian deployments and repositories

3 : ksvalidator was not found, install pykickstart

4 : The default password used by the sample templates for newlyinstalled machines (default_password_crypted in /etc/cobbler/settings) is stillset to 'cobbler' and should be changed, try: "openssl passwd -1 -salt'random-phrase-here' 'your-password-here'"
to generate new one

5 : fencing tools were not found, and are required to use the(optional) power management features. install cman or fence-agents to use them

 

第1个问题解决办法：执行命令cobblerget-loaders或者到/usr/share/syslinux/目录中复制相应的文件到/var/lib/cobbler/loaders/即可。

 

第2个问题解决办法：debian 安装用，暂时可以不管;如果需要安装，下载地址为：http://rpmfind.net/linux/rpm2html/search.php?query=debmirror

 

 

第3个问题解决办法：安装pykickstart软件，yum install pykickstart –y

 

第4个问题解决办法：对root密码修改

shell>openssl passwd -apr1 -salt 'openssl rand -hex 4'

Password: #输入密码

$apr1$openssl $/vGgWVz8WEUqzbz6kBoVb0

shell>vim/etc/cobbler/setting

default_password_crypted: "$/vGgWVz8WEUqzbz6kBoVb0"        //将引号中的内容替换成上面的字符串

 

第5个问题解决办法：执行命令# yuminstall cman fence-agents –y

 

 

安装完之后再次启动cobblerd服务，并用cobblersync命令进行同步，再检查

cobbler check

 

 

 

安装cobbler的WEB管理

yum -y cobbler-web

vim /etc/cobbler/modules.conf

[authentication]

         module = authn_pam

 

添加cobbler用户添加cobbler密码

>useradd cobbleradmin

>passwd cobbleradmin

 

 

编辑/etc/cobbler/users.conf配置文件

[admins]

admin = “cobbleradmin”

Cobbler = “”

 

重启cobblerd

service cobblerd restart

重启一下httpd

service  httpd restart
