加载epel源# rpm -Uvh http://mirrors.ustc.edu.cn/epel/ ... ease-6-8.noarch.rpm
或者
# rpm -ivh http://dl.fedoraproject.org/pub/ ... ease-6-8.noarch.rpm
安装cobbler包及其组件# yum install -y cobbler rsync tftp dhcphttpd cman pykickstart debmirror tftp-server xinetd python-ctypes
# yum install -y ed patch perlperl-Compress-Zlib perl-Digest-SHA1 perl-LockFile-Simple perl-libwww-perl
设置服务开机启动# chkconfig httpd on
# chkconfig dhcpd on
# chkconfig xinetd on
# chkconfig cobblerd on
系统环境设置selinux/iptables# sed -i '/SELINUX/s/enforcing/disabled/'/etc/selinux/config
# setenforce 0
# chkconfig iptables off
# service iptables stop
修改httpd配置并启动# vim /etc/httpd/conf/httpd.conf
ServerName 127.0.0.1:80
# service httpd start
修改cobbler配置并启动设置目标系统root密码# PASSWORD=”`echo "zhangdh.com" |openssl passwd -1 -salt 'randomstr' –stdin`”
# sed -is@"^default_password_crypted.*$"@"default_password_crypted:\"$PASSWORD\""@g /etc/cobbler/settings
设置cobbler server的IP# sed -i 's/server: 127.0.0.1/server:10.240.216.1/g' /etc/cobbler/settings
设置DHCP server的IP# sed -i 's/next_server:127.0.0.1/next_server: 10.240.216.1/g' /etc/cobbler/settings
设置允许cobbler管理DHCP# sed -i 's/manage_dhcp: 0/manage_dhcp:1/g' /etc/cobbler/settings
设置允许cobbler管理rsync# sed -i 's/manage_rsync: 0/manage_rsync:1/g' /etc/cobbler/settings
设置一次安装开关（可选）# sed -i 's/pxe_just_once: 0/pxe_just_once:1/g' /etc/cobbler/settings
修改cobbler管理DHCP的模板# cat /etc/cobbler/dhcp.template
ddns-update-style interim;

allow booting;
allow bootp;

ignore client-updates;
set vendorclass = optionvendor-class-identifier;

option pxe-system-type code 93 = unsignedinteger 16;

subnet 10.240.216.0 netmask 255.255.255.0 {
    option routers            10.240.216.254;     #路由地址
    #option domain-name-servers 8.8.8.8;                            #DNSserver地址
    option subnet-mask        255.255.255.0;             #子网掩码
     #rangedynamic-bootp        10.240.216.210.240.216.200;  #分配IP地址段
    default-lease-time         21600;
    max-lease-time             43200;
    next-server               $next_server;
    filename                  "pxelinux.0";
}
subnet 10.240.217.0 netmask 255.255.255.0 {
    option routers            10.240.217.254;
    option subnet-mask        255.255.255.0;
    filename                  "/pxelinux.0";
    default-lease-time         21600;
    max-lease-time             43200;
    next-server               $next_server;
}
注：可添加很多个子网...
启动cobbler# service cobblerd start
校验cobbler安装条件# cobbler check
更新loader信息# cobbler get-loaders
修改xinetd关于tftp和rsync的配置并启动# sed -i '/disable/c\\tdisable\t\t\t= no'/etc/xinetd.d/tftp
# sed -i -e 's/\=\ yes/\=\ no/g'/etc/xinetd.d/rsync
# service xinetd start
配置dhcp server并启动# cat /etc/dhcp/dhcpd.conf
ddns-update-style interim;

allow booting;
allow bootp;

ignore client-updates;
set vendorclass = optionvendor-class-identifier;

option pxe-system-type code 93 = unsignedinteger 16;
#可以添加多子网（保持和dhcp.template一致）
subnet 10.240.216.0 netmask 255.255.255.0 {
    option routers            10.240.216.254;
    option subnet-mask        255.255.255.0;
    filename                  "/pxelinux.0";
     #rangedynamic-bootp        10.240.216.210.240.216.200;
    default-lease-time         21600;
    max-lease-time             43200;
    next-server               10.240.216.1;
}
subnet 10.240.217.0 netmask 255.255.255.0 {
    option routers            10.240.217.254;
    option subnet-mask         255.255.255.0;
    filename                  "/pxelinux.0";
    default-lease-time         21600;
    max-lease-time             43200;
    next-server               10.240.216.1;

# service dhcpd start
修改debmirror.conf去掉仅对debian系统的支持参数# sed -i "s/^@dists/#@dists/g"/etc/debmirror.conf
# sed -i "s/^@arches/#@arches/g"/etc/debmirror.conf
Cobbler配置同步# service cobblerd restart
# cobbler sync
挂载安装镜像并导入distro# mkdir /mnt/rhel6.5

将自定义的kickstart文件与镜像相关联# cobbler profile edit--name=redhat6.5-x86_64 --distro=redhat6.5-x86_64--kickstart=/var/lib/cobbler/kickstarts/rhel6.5.ks
再次同步cobbler配置# cobbler sync                         ###下面贴出完整信息，注意红色部分
