7实现PXE支持centos6和7的系统安装
注意：
1 改成独立的网段vnnet12，非桥接，dhcp功能禁用
2 禁用iptables和selinux
1 yum install httpd dhcp tftp-server syslinux
2 cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
subnet 192.168.37.0 netmask 255.255.255.0 {
range 192.168.37.10 192.168.37.100;
next-server 192.168.37.107;
filename "pxelinux.0";
}
systemctl start dhcpd
systemctl enable dhcpd
3 systemctl enable tftp
systemctl start tftp
4 systemctl enable httpd
systemctl start httpd

cobbler安装（基于epel源）：
·设置开机启动systemctl enable httpd tftp cobblerd（安装cobbler之后有cobbler这个服务需要启动）
启动服务 systemctl start httpd tftp cobblerd
·vim /etc/obbler/settings (编辑cobbler配置文件，在server，next_server，default_password_crypted行修改，1.自己服务器ip，2.tftp的ip（本机是TFTP服务就是本机ip）,3.默认密码)
·cp /usr/share/syslinux/{pxelinux.0,menu.c32} /var/lib/tftpboot/
·vim /etc/cobbler/dhcp.template (修改网络ip地址和地址段)
·cobbler sync（修改完执行，自动导入到dhcp配置文件里）
·cobbler import --path=/misc/cd/ --name=centos7.3 --arch=x86_64(导入系统光盘到cobbler，--path为光盘路径|cobbler distro list命令查看导入的系统！可以导入多个，指定多个多个光盘路径)
#·/var/www/cobbler/ks_mirror(上一步导入，导入到当前目录下)
#·自己制定ks.cfg（应答文件）文件时指定特定路径(url --url=$tree)
·添加启动菜单项：
--name为启动时的菜单选项
--distro为cobbler distro list的选项（yum源选项）
--kickstart应答文件存放路径必须为此路径
·启动菜单选项删除：
·
基于web的cobbler：
·yum install cobbler-web
·添加用户首次添加需要加上-c选项，之后添加就不需要。
·第二种添加用户
useradd –s /sbin/nologin xxx1
echo xxx2 | passwd –stdin xxx1
vim /etc/cobbler/user.conf
