服务器评测
Cobbler是一个快速安装Linux系统的网络安装服务套件，集成了PXE、DHCP、DNS/Kickstart服务管理和yum仓库管理工具，通过PXE网络引导安装，配置简单。
部署准备：
关闭防火墙：service iptablesstop
关闭selinux：setenforce 0
安装epel源：rpm -ivh http://download.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
1、安装相关软件
[root@localhost ~]# yum install -y cobbler tftp dhcp httpdcman pykickstart
2、配置tftp-server和rsync
[root@localhost ~]# vi /etc/xinetd.d/tftp
disable = no #开启
[root@localhost ~]# vi /etc/xinetd.d/rsync
disable = no
[root@localhost ~]# /etc/init.d/xinetd restart
3、配置DHCP
[root@localhost ~]# vi /etc/dhcp/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 192.168.0.0 netmask 255.255.255.0 {
range dynamic-bootp192.168.0.200 192.168.0.210;
optionbroadcast-address 192.168.0.254;
option routers192.168.0.1;
optiondomain-name-servers 192.168.0.1;
default-lease-time600;
max-lease-time 7200;
filename “pxelinux.0”;
next-server192.168.0.202;
}
[root@localhost ~]# /etc/init.d/dhcpd restart
4、执行检查，修改提示问题
1>.修改/etc/cobbler/settings里cobbler server地址
2>.修改/etc/cobbler/settings里next_server地址
3>.执行cobbler get-loaders，下载loader程序
4>.提示没有安装debmirror，如果不是debian类的系统可忽略
5>.修改cobbler用户默认密码，然后替换/etc/cobbler/settings中的密码
生成密码：openssl passwd -1-salt ‘1234.com’ ‘123.com’
#1234.com是干扰码，用于加在密文中。123.com是安装新系统root密码
替换密文：default_password_crypted:”$1$1234.com$P8CiR10xiKXSQKJwofdsh0″
6>.执行cobbler sync命令，让cobbler接管服务,应用配置
[root@localhost ~]# /etc/init.d/cobblerd restart
5、修改cobbler配置文件让cobbler来管理相关服务
[root@localhost ~]# vi /etc/cobbler/settings
manage_dhcp: 1
manage_tftpd: 1
manage_rsync: 1
pxe_just_once: 1
6、导入CentOS系统
先可以挂载iso镜像，从光驱中导入cobbler：
[root@localhost ~]# mount -o loop RHEL-server-6.0-i386-dvd.iso /media
[root@localhost ~]# cobbler import -path=/media –name=rhel6
7、通过cobbler list查看现在的镜像，通过测试机开机设置网络启动，实现无人值守安装
