kicistart 部署linux（實驗失敗，待排錯）

實驗環境：
    centos7.1
    vmware worksation 11

實驗設備：
    kick.test.com 服務端（kickstart+dhcp+dns+vsftp+tftp）

    client 客戶端（1G內存）
        注意內存最小1G，否則回報out of memory的錯誤。

所需服務:
    1.DHCP
    2.tftp-server
    2.VSFTP
    3.DNS

所需文件：
    1.vmlinuz
    2.initrd
    3.ks.cfg kickstart 應答文件
    4.pxelinux.0文件
    5.系統光盤鏡像



部署過程：
    假設服務器所在網段爲192.168.225.0 255.255.255.0，服務器ip地址爲192.168.225.3，主機名爲kick.test.com

    1.安裝配置dhcp
        #yum install dhcp -y
        #cat /usr/share/doc/dhcp-xxx/dhcpd.conf.example > /etc/dhcp/dhcpd.conf
        #vim /etc/dhcp/dhcpd.conf
            subnet 192.168.225.0 netmask 255.255.255.0{
                range 192.168.225.100 192.168.225.150;
                option domain-name-servers 192.168.225.3;
                option domain-name "test.com";
                option routers 192.168.225.3;
                option broadcast-address 192.168.225.255;
                default-lease-time 600;
                max-lease-time 7200;
                filename "/pxelinux.0";  指定pxelinux.0文件在ftp上的位置。
                next-server 192.168.225.3; 指定ftp服務器的ip地址
            }
        #systemctl start dhcpd

    2.安裝配置tftp
        #yum install tftp-server -y
        #vim /etc/xinetd.d/tftp
            service tftpd{
                ...
                disable = no
            }

        #systemctl restart xinted
        #netstat -ntupl|grep :69
       
        #mkdir /var/lib/tftpboot/pxelinux.cfg 創建tftpd服務配置文件目錄，必須爲此名字，不能修改。

        #cp /isofile/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinu.cfg/default

        #vim /var/lib/tftpboot/pxelinu.cfg/default
        default linux  指定默認使用的lable
        lable linux
        ...
        append ...  ks=ftp://192.168.225.3/ks.cfg 指定ks.cfg的位置

        #cp /iso/isolinux/boot.msg /var/lib/tftpboot/pxelinu.cfg/boot.msg 複製歡迎信息

        #vim /var/lib/tftpboot/pxelinu.cfg/boot.msg
        可以使用

        #chmod u+x /var/lib/tftpboot/pxelinu.cfg/default
        #chmod u+x /var/lib/tftpboot/pxelinu.cfg/boot.msg



    3.複製文件到tftp根目錄下
        #yum -y install syslinux
        #rpm -ql syslinux|grep  pxelinux.0
        #cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

        #cp /isofile/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/

    4.安裝ftp並複製光盤文件到ftp根目錄下：
        #yum install vsftpd -y
        #systemctl start vsftpd
        #mkdir /var/ftp/iso
        #cp -a /isofile/* /var/ftp/iso/


    5.配置DNS（可選，主要作用是提供主機名）
        #yum install bind -y
        #vim /etc/named.conf
            options {
                listen-on port 53 { any; };
                ...
                allow-query     { any; };

            zone "test.com" IN {
                type master ;
                file 'test.com'
            };

            zone "30.168.192.in-addr.arpa" IN {
                type master;
                file "192.168.225.zone"
            };

        #cd /etc/named/
        #cp -a /var/named/named.localhost test.com
        #vim test.com
            $TTL 86400
            $GENERATE 100-150 system$ A 192.168.225.$
            @ IN SOA test.com. (
                1
                1D
                1H
                1W
                3H
            )
            NS kick.test.com.
            kick A 192.168.225.3

        #cp -a test.com 192.168.225.zone

        #vim 192.168.225.zone
            $TTL 86400
            $GENERATE 100-150 system$ PTR system$.test.com.
            @ IN SOA test.com (
                1
                1D
                1H
                1W
                3H
            )
            NS kick.test.com.
            3 PTR kick.test.com.

        #rndc-confgen -r /dev/urandom -a
        #vim /etc/resovle.conf
            nameserver 127.0.0.1

        #systemctl start named



    6.應答文件
        #yum install system-config-kickstart -y
        #system-config-kickstart &

        #cp ks.cfg /var/ftp/
